It’s 30% smaller than traditional 20” folding bikes, and folds small enough to fit into lockers and narrow spaces"],"attrs_boilerpipe_text":"Meet the BYB\nWanna go everywhere with your bike, but held back by cumbersome logistics? Say hello to the BYB! This ultra-compact folding bike travels unassumingly small to fit whatever mode of transportation you choose, but delivers an impressively bigger ride. So Bring Your Bike, and answer wherever the paved road may call.\nThe BYB is 30% smaller than traditional 20” folding bikes, and folds small and slim enough to fit into any narrow space such as behind doors or in lockers for handy, worry-free storage.\nWith limited apartment space no longer an issue for the small, slim BYB, the question now is what you want to get done with your bike. The BYB S11 and P8 are geared towards urban intermodal commuters who could use a little extra help when weaving through busy transit stations with their bike, while the BYB P10 is a lighter, sportier option for those who want to maximize their riding experience within precious free time.\nThe BYB is designed for commuting, but doesn’t just stop there. It also lets you bring your stuff, whether that’s a change of clothes, workout gear, or your laptop bag. Plus, the Metro Transit Rack on the BYB S11 and P8 further provides you options aplenty—add panniers, bags, racks, and baskets from Ortlieb and KlickFix to customize your ride.\nThe BYB is perfect for mixed-mode commuters who do a stretch of their daily journey on a train or bus, or might grab a taxi home on a rainy day. Folded, the BYB fits anywhere so all your transport options are always open.\nWhen equipped with the Metro Transit Rack, the folded BYB stands upright with one of the smallest footprints of any folding bike—and the rack’s built-in spinner wheels let you trolley the compactly folded bike through busy transit stations and onto crowded trains and buses with one hand while the other holds your coffee.\nThe best things in life are shared, including your folding bike. The BYB has a low-step frame design and resizes in seconds—no tools required—to fit riders between 147 and 195 cm (4’10” – 6’5”), so you can share the bike with anyone in your family.\nThe new BYB P10 includes everything that makes the BYB tons of fun to ride, while trading in commuter-focused features like the fenders, rear rack, and chainguard for a lighter, sportier bike. But make no mistake—it’s just as compact and ready to accompany you on all your free-time adventures.\nNo matter how small or fast a bike folds, it needs to be a bike you want to ride in your hard-earned free time. The BYB champions the weekend warrior in you with a frame engineered for stiffness, 20” wheels, and performance components. All that’s needed is the desire to get out and ride!\nTaking your bike on vacation? With accessories like the lightweight PopCover and padded Stow Bag designed for storing and transporting the BYB, you can go from riding to packed bike in 60 seconds. Even air travel is made a whole lot simpler: just pop the folded BYB into the AirPorter Slim suitcase—no disassembly required.\nTriFold technology is a patented new way to fold a bike small while delivering a quality ride.\nWith an organically curved form optimized for strength, the TFL Joint is our most advanced yet and includes a number of critical new technologies.\nNext to the frame, the Physis RF—our new 3D-forged handlepost—is the most important component contributing to the BYB’s stiff and responsive ride.\nThe Andros is our tool-free adjustable stem—it lets you adjust your riding position by setting your handlebars exactly where you want.\nRoll the BYB like a spinner suitcase and easily maneuver the folded bike in crowded rail or bus stations. The Metro Transit Rack carries up to 20 kg (44 lb) and allows the BYB to stand vertically. Equipped on the BYB S11 and BYB P8.\nSecurely locks the sections of the\nBYB\ntogether when rolling or carrying the bike. Depress the lever and the clever release mechanism ejects the Anchor Bolt, making it easier to unfold.\nThe BYB inherits important technology—DoubleDeck frame design and the burly trapezoidal tubing—from the Tern GSD, ensuring extra stiffness and durability.\nThe same robust mount found on our cargo-focused GSD. The Combo Mount lets you install a variety of different racks, bags, and baskets to your BYB so you can also bring your stuff.\nLight, fast, and strong, Kinetix Pro and Pro X Wheels are hand-built with custom hubs and feature Rolf® Paired Spoke Technology.\nClose the lever and a metal deadbolt slides smoothly into place, locking the hinge. Once you close the TFL, it stays locked in place.\nEnsures that your properly adjusted lever always stays at the proper tension, even after thousands of cycles of folding and unfolding.\nWhereas most other folding bikes weld a simple tube to a plate, the TFL Joint features precision-machined inserts at the tube junction, ensuring more consistent welding and more material at the most highly stressed areas.\nSliding bearings between the moving parts make sure that the folding action is always smooth and friction-free. These bearings are serviceable so if after a few years of hard use the bearings have worn down, your dealer can easily swap them out to refresh your bike.","attrs_markdown":"[Skip to main content](https:\/\/www.ternbicycles.com\/us\/bikes\/471\/byb#main-content)\n\n- [Bikes](https:\/\/www.ternbicycles.com\/us\/bikes)\n  \n  Toggle submenu\n  -

Say hello to the BYB! This ultra-compact folding bike travels unassumingly small to fit whatever mode of transportation you choose, but delivers an impressively bigger ride. So Bring Your Bike, and answer wherever the paved road may call.\n\n[See the models](https:\/\/www.ternbicycles.com\/us\/bikes\/471\/byb#bike-models)\n\n![BYB: Fast Folding Bike](https:\/\/www.ternbicycles.com\/sites\/default\/files\/images\/bikes\/keybike\/byb\/TN-byb-folding-stop-motion.gif)\n\n![BYB: ultra slim folding bike](https:\/\/www.ternbicycles.com\/sites\/default\/files\/images\/bikes\/keybike\/byb\/TN-byb-g1-slimfold.jpg)\n\n## Easy Storage & Safekeeping\nThe BYB is 30% smaller than traditional 20” folding bikes, and folds small and slim enough to fit into any narrow space such as behind doors or in lockers for handy, worry-free storage.\n\n![BYB ultra compact folding bike - urban](https:\/\/www.ternbicycles.com\/sites\/default\/files\/2023-04\/byb-urban.jpg)\n\n## Urban or Sporty?\nWith limited apartment space no longer an issue for the small, slim BYB, the question now is what you want to get done with your bike. The BYB S11 and P8 are geared towards urban intermodal commuters who could use a little extra help when weaving through busy transit stations with their bike, while the BYB P10 is a lighter, sportier option for those who want to maximize their riding experience within precious free time.\n\n![BYB ultra compact folding bike - sporty](https:\/\/www.ternbicycles.com\/sites\/default\/files\/2023-04\/byb-sporty.jpg)\n\n## All-round Commuter\nThe BYB is designed for commuting, but doesn’t just stop there. It also lets you bring your stuff, whether that’s a change of clothes, workout gear, or your laptop bag. Plus, the Metro Transit Rack on the BYB S11 and P8 further provides you options aplenty—add panniers, bags, racks, and baskets from Ortlieb and KlickFix to customize your ride.\n\n![BYB: Carry More on Your Folding Bike](https:\/\/www.ternbicycles.com\/sites\/default\/files\/images\/bikes\/keybike\/byb\/TN-byb-s11-carrymore.gif)\n\n![BYB: Multimodal commuter](https:\/\/www.ternbicycles.com\/sites\/default\/files\/2023-04\/byb-mixitup.jpg)\n\n## Mix It Up\nThe BYB is perfect for mixed-mode commuters who do a stretch of their daily journey on a train or bus, or might grab a taxi home on a rainy day. Folded, the BYB fits anywhere so all your transport options are always open.\n\n![BYB: Ready to roll folding bike](https:\/\/www.ternbicycles.com\/sites\/default\/files\/images\/bikes\/keybike\/byb\/TN-byb-g1-readytoroll.jpg)\n\n## Compact and Ready to Roll\nWhen equipped with the Metro Transit Rack, the folded BYB stands upright with one of the smallest footprints of any folding bike—and the rack’s built-in spinner wheels let you trolley the compactly folded bike through busy transit stations and onto crowded trains and buses with one hand while the other holds your coffee.\n\n## Share Your Ride\nThe best things in life are shared, including your folding bike. The BYB has a low-step frame design and resizes in seconds—no tools required—to fit riders between 147 and 195 cm (4’10” – 6’5”), so you can share the bike with anyone in your family.\n\n![BYB: Fits the Entire Fmaily](https:\/\/www.ternbicycles.com\/sites\/default\/files\/images\/bikes\/keybike\/byb\/TN-byb-g1-onesize.png)\n\n## The New BYB P10: Your Sidekick for Free-Time Adventures\nThe new BYB P10 includes everything that makes the BYB tons of fun to ride, while trading in commuter-focused features like the fenders, rear rack, and chainguard for a lighter, sportier bike. But make no mistake—it’s just as compact and ready to accompany you on all your free-time adventures.\n\n![BYB: Folding bike](https:\/\/www.ternbicycles.com\/sites\/default\/files\/2023-05\/TN-photo-BYB_P10-00-satin-red-web.jpg)\n\n![BYB: A folding bike for the weekend warrior](https:\/\/www.ternbicycles.com\/sites\/default\/files\/2023-04\/byb-weekendwarrior.jpg)\n\n## Weekend Warrior Ready\nNo matter how small or fast a bike folds, it needs to be a bike you want to ride in your hard-earned free time. The BYB champions the weekend warrior in you with a frame engineered for stiffness, 20” wheels, and performance components. All that’s needed is the desire to get out and ride\\!\n\n![BYB: How to Store a Folding Bike](https:\/\/www.ternbicycles.com\/sites\/default\/files\/images\/bikes\/keybike\/byb\/TN-byb-storage-animation.gif)\n\n## Ready for Departure\nTaking your bike on vacation? With accessories like the lightweight PopCover and padded Stow Bag designed for storing and transporting the BYB, you can go from riding to packed bike in 60 seconds. Even air travel is made a whole lot simpler: just pop the folded BYB into the AirPorter Slim suitcase—no disassembly required.\n\n![BYB in an Airporter Slim](https:\/\/www.ternbicycles.com\/sites\/default\/files\/images\/bikes\/keybike\/byb\/TN-byb-airporterslim-airport.jpg)\n\n## A stylish premium folding bike with an innovative and intuitive folding concept\n[Watch](http:\/\/www.radfahren.de\/test-teile\/tern-byb-s11-test)\n\n### \\- aktiv Radfahren\n\n## Why the BYB?\n![BYB-trifold](https:\/\/www.ternbicycles.com\/sites\/default\/files\/images\/bikes\/keybike\/byb\/TN-byb-g1-tech-trifold.jpg)\n\n## TriFold Technology\nTriFold technology is a patented new way to fold a bike small while delivering a quality ride.\n\n![BYB-TFL-joint](https:\/\/www.ternbicycles.com\/sites\/default\/files\/images\/bikes\/keybike\/byb\/TN-byb-g1-tech-tfl.jpg)\n\n## TFL Joint\nWith an organically curved form optimized for strength, the TFL Joint is our most advanced yet and includes a number of critical new technologies.\n\n![BYB-physis-rf](https:\/\/www.ternbicycles.com\/sites\/default\/files\/images\/bikes\/keybike\/byb\/TN-byb-g1-tech-physis-rf.jpg)\n\n## Physis RF\nNext to the frame, the Physis RF—our new 3D-forged handlepost—is the most important component contributing to the BYB’s stiff and responsive ride.\n\n![BYB-andros](https:\/\/www.ternbicycles.com\/sites\/default\/files\/images\/bikes\/keybike\/byb\/TN-byb-g1-tech-andros.jpg)\n\n## Andros Stem\nThe Andros is our tool-free adjustable stem—it lets you adjust your riding position by setting your handlebars exactly where you want.\n\n![BYB-metro-transit](https:\/\/www.ternbicycles.com\/sites\/default\/files\/images\/bikes\/keybike\/byb\/TN-byb-g1-tech-metro-transit.jpg)\n\n## Metro Transit Rack\nRoll the BYB like a spinner suitcase and easily maneuver the folded bike in crowded rail or bus stations. The Metro Transit Rack carries up to 20 kg (44 lb) and allows the BYB to stand vertically. Equipped on the BYB S11 and BYB P8.\n\n![BYB-anchor-bolt](https:\/\/www.ternbicycles.com\/sites\/default\/files\/images\/bikes\/keybike\/byb\/TN-byb-g1-tech-anchor-bolt.jpg)\n\n## Anchor Bolt\nSecurely locks the sections of the BYB together when rolling or carrying the bike. Depress the lever and the clever release mechanism ejects the Anchor Bolt, making it easier to unfold.\n\n![BYB-GSDna](https:\/\/www.ternbicycles.com\/sites\/default\/files\/images\/bikes\/keybike\/byb\/TN-byb-g1-tech-gsdna.jpg)\n\n## DoubleDeck Frame\nThe BYB inherits important technology—DoubleDeck frame design and the burly trapezoidal tubing—from the Tern GSD, ensuring extra stiffness and durability.\n\n![BYB-combo-mount](https:\/\/www.ternbicycles.com\/sites\/default\/files\/images\/bikes\/keybike\/byb\/TN-byb-g1-tech-combo-mount.jpg)\n\n## Combo Mount\nThe same robust mount found on our cargo-focused GSD. The Combo Mount lets you install a variety of different racks, bags, and baskets to your BYB so you can also bring your stuff.\n\n![BYB-kinetixProXWheels](https:\/\/www.ternbicycles.com\/sites\/default\/files\/images\/bikes\/keybike\/byb\/TN-byb-g1-tech-KxPro-wheel.jpg)\n\n## Kinetix Pro X Wheels\nLight, fast, and strong, Kinetix Pro and Pro X Wheels are hand-built with custom hubs and feature Rolf® Paired Spoke Technology.\n\n## A Closer Look at the TFL Joint\n![BYB-tfl](https:\/\/www.ternbicycles.com\/sites\/default\/files\/images\/bikes\/keybike\/byb\/TN-byb-g1-tfl2.jpg)\n\n1DeadBolt Design\n\nClose the lever and a metal deadbolt slides smoothly into place, locking the hinge. Once you close the TFL, it stays locked in place.\n\n2SpringLock Technology\n\nEnsures that your properly adjusted lever always stays at the proper tension, even after thousands of cycles of folding and unfolding.\n\n![BYB-tfl](https:\/\/www.ternbicycles.com\/sites\/default\/files\/images\/bikes\/keybike\/byb\/TN-byb-g1-tfl1.jpg)\n\n33D Interface\n\nWhereas most other folding bikes weld a simple tube to a plate, the TFL Joint features precision-machined inserts at the tube junction, ensuring more consistent welding and more material at the most highly stressed areas.\n\n4Igus® bearings\n\nSliding bearings between the moving parts make sure that the folding action is always smooth and friction-free. These bearings are serviceable so if after a few years of hard use the bearings have worn down, your dealer can easily swap them out to refresh your bike.\n\n## Select Your Model\n##\n[![BYB P8:

Say hello to the BYB! This ultra-compact folding bike travels unassumingly small to fit whatever mode of transportation you choose, but delivers an impressively bigger ride. So Bring Your Bike, and answer wherever the paved road may call. [See the models](https://www.ternbicycles.com/us/bikes/471/byb#bike-models) ![BYB: Fast Folding Bike](https://www.ternbicycles.com/sites/default/files/images/bikes/keybike/byb/TN-byb-folding-stop-motion.gif) ![BYB: ultra slim folding bike](https://www.ternbicycles.com/sites/default/files/images/bikes/keybike/byb/TN-byb-g1-slimfold.jpg) ## Easy Storage & Safekeeping The BYB is 30% smaller than traditional 20” folding bikes, and folds small and slim enough to fit into any narrow space such as behind doors or in lockers for handy, worry-free storage. ![BYB ultra compact folding bike - urban](https://www.ternbicycles.com/sites/default/files/2023-04/byb-urban.jpg) ## Urban or Sporty? With limited apartment space no longer an issue for the small, slim BYB, the question now is what you want to get done with your bike. The BYB S11 and P8 are geared towards urban intermodal commuters who could use a little extra help when weaving through busy transit stations with their bike, while the BYB P10 is a lighter, sportier option for those who want to maximize their riding experience within precious free time. ![BYB ultra compact folding bike - sporty](https://www.ternbicycles.com/sites/default/files/2023-04/byb-sporty.jpg) ## All-round Commuter The BYB is designed for commuting, but doesn’t just stop there. It also lets you bring your stuff, whether that’s a change of clothes, workout gear, or your laptop bag. Plus, the Metro Transit Rack on the BYB S11 and P8 further provides you options aplenty—add panniers, bags, racks, and baskets from Ortlieb and KlickFix to customize your ride. ![BYB: Carry More on Your Folding Bike](https://www.ternbicycles.com/sites/default/files/images/bikes/keybike/byb/TN-byb-s11-carrymore.gif) ![BYB: Multimodal commuter](https://www.ternbicycles.com/sites/default/files/2023-04/byb-mixitup.jpg) ## Mix It Up The BYB is perfect for mixed-mode commuters who do a stretch of their daily journey on a train or bus, or might grab a taxi home on a rainy day. Folded, the BYB fits anywhere so all your transport options are always open. ![BYB: Ready to roll folding bike](https://www.ternbicycles.com/sites/default/files/images/bikes/keybike/byb/TN-byb-g1-readytoroll.jpg) ## Compact and Ready to Roll When equipped with the Metro Transit Rack, the folded BYB stands upright with one of the smallest footprints of any folding bike—and the rack’s built-in spinner wheels let you trolley the compactly folded bike through busy transit stations and onto crowded trains and buses with one hand while the other holds your coffee. ## Share Your Ride The best things in life are shared, including your folding bike. The BYB has a low-step frame design and resizes in seconds—no tools required—to fit riders between 147 and 195 cm (4’10” – 6’5”), so you can share the bike with anyone in your family. ![BYB: Fits the Entire Fmaily](https://www.ternbicycles.com/sites/default/files/images/bikes/keybike/byb/TN-byb-g1-onesize.png) ## The New BYB P10: Your Sidekick for Free-Time Adventures The new BYB P10 includes everything that makes the BYB tons of fun to ride, while trading in commuter-focused features like the fenders, rear rack, and chainguard for a lighter, sportier bike. But make no mistake—it’s just as compact and ready to accompany you on all your free-time adventures. ![BYB: Folding bike](https://www.ternbicycles.com/sites/default/files/2023-05/TN-photo-BYB_P10-00-satin-red-web.jpg) ![BYB: A folding bike for the weekend warrior](https://www.ternbicycles.com/sites/default/files/2023-04/byb-weekendwarrior.jpg) ## Weekend Warrior Ready No matter how small or fast a bike folds, it needs to be a bike you want to ride in your hard-earned free time. The BYB champions the weekend warrior in you with a frame engineered for stiffness, 20” wheels, and performance components. All that’s needed is the desire to get out and ride\! ![BYB: How to Store a Folding Bike](https://www.ternbicycles.com/sites/default/files/images/bikes/keybike/byb/TN-byb-storage-animation.gif) ## Ready for Departure Taking your bike on vacation? With accessories like the lightweight PopCover and padded Stow Bag designed for storing and transporting the BYB, you can go from riding to packed bike in 60 seconds. Even air travel is made a whole lot simpler: just pop the folded BYB into the AirPorter Slim suitcase—no disassembly required. ![BYB in an Airporter Slim](https://www.ternbicycles.com/sites/default/files/images/bikes/keybike/byb/TN-byb-airporterslim-airport.jpg) ## A stylish premium folding bike with an innovative and intuitive folding concept [Watch](http://www.radfahren.de/test-teile/tern-byb-s11-test) ### \- aktiv Radfahren ## Why the BYB? ![BYB-trifold](https://www.ternbicycles.com/sites/default/files/images/bikes/keybike/byb/TN-byb-g1-tech-trifold.jpg) ## TriFold Technology TriFold technology is a patented new way to fold a bike small while delivering a quality ride. ![BYB-TFL-joint](https://www.ternbicycles.com/sites/default/files/images/bikes/keybike/byb/TN-byb-g1-tech-tfl.jpg) ## TFL Joint With an organically curved form optimized for strength, the TFL Joint is our most advanced yet and includes a number of critical new technologies. ![BYB-physis-rf](https://www.ternbicycles.com/sites/default/files/images/bikes/keybike/byb/TN-byb-g1-tech-physis-rf.jpg) ## Physis RF Next to the frame, the Physis RF—our new 3D-forged handlepost—is the most important component contributing to the BYB’s stiff and responsive ride. ![BYB-andros](https://www.ternbicycles.com/sites/default/files/images/bikes/keybike/byb/TN-byb-g1-tech-andros.jpg) ## Andros Stem The Andros is our tool-free adjustable stem—it lets you adjust your riding position by setting your handlebars exactly where you want. ![BYB-metro-transit](https://www.ternbicycles.com/sites/default/files/images/bikes/keybike/byb/TN-byb-g1-tech-metro-transit.jpg) ## Metro Transit Rack Roll the BYB like a spinner suitcase and easily maneuver the folded bike in crowded rail or bus stations. The Metro Transit Rack carries up to 20 kg (44 lb) and allows the BYB to stand vertically. Equipped on the BYB S11 and BYB P8. ![BYB-anchor-bolt](https://www.ternbicycles.com/sites/default/files/images/bikes/keybike/byb/TN-byb-g1-tech-anchor-bolt.jpg) ## Anchor Bolt Securely locks the sections of the BYB together when rolling or carrying the bike. Depress the lever and the clever release mechanism ejects the Anchor Bolt, making it easier to unfold. ![BYB-GSDna](https://www.ternbicycles.com/sites/default/files/images/bikes/keybike/byb/TN-byb-g1-tech-gsdna.jpg) ## DoubleDeck Frame The BYB inherits important technology—DoubleDeck frame design and the burly trapezoidal tubing—from the Tern GSD, ensuring extra stiffness and durability. ![BYB-combo-mount](https://www.ternbicycles.com/sites/default/files/images/bikes/keybike/byb/TN-byb-g1-tech-combo-mount.jpg) ## Combo Mount The same robust mount found on our cargo-focused GSD. The Combo Mount lets you install a variety of different racks, bags, and baskets to your BYB so you can also bring your stuff. ![BYB-kinetixProXWheels](https://www.ternbicycles.com/sites/default/files/images/bikes/keybike/byb/TN-byb-g1-tech-KxPro-wheel.jpg) ## Kinetix Pro X Wheels Light, fast, and strong, Kinetix Pro and Pro X Wheels are hand-built with custom hubs and feature Rolf® Paired Spoke Technology. ## A Closer Look at the TFL Joint ![BYB-tfl](https://www.ternbicycles.com/sites/default/files/images/bikes/keybike/byb/TN-byb-g1-tfl2.jpg) 1DeadBolt Design Close the lever and a metal deadbolt slides smoothly into place, locking the hinge. Once you close the TFL, it stays locked in place. 2SpringLock Technology Ensures that your properly adjusted lever always stays at the proper tension, even after thousands of cycles of folding and unfolding. ![BYB-tfl](https://www.ternbicycles.com/sites/default/files/images/bikes/keybike/byb/TN-byb-g1-tfl1.jpg) 33D Interface Whereas most other folding bikes weld a simple tube to a plate, the TFL Joint features precision-machined inserts at the tube junction, ensuring more consistent welding and more material at the most highly stressed areas. 4Igus® bearings Sliding bearings between the moving parts make sure that the folding action is always smooth and friction-free. These bearings are serviceable so if after a few years of hard use the bearings have worn down, your dealer can easily swap them out to refresh your bike. ## Select Your Model ## [![BYB P8: Compact Folding Bike for Urban Commuting](https://www.ternbicycles.com/sites/default/files/styles/small_rectangle_1x/public/images/bikes/unfolded/2019/08/byb-p8-g1-unfold-d0-silverblue_0.jpg.webp?itok=1B4ljcLY)](https://www.ternbicycles.com/us/bikes/471/byb-p8) ##

Readable Markdown	Meet the BYB Wanna go everywhere with your bike, but held back by cumbersome logistics? Say hello to the BYB! This ultra-compact folding bike travels unassumingly small to fit whatever mode of transportation you choose, but delivers an impressively bigger ride. So Bring Your Bike, and answer wherever the paved road may call. ![BYB: Fast Folding Bike](https://www.ternbicycles.com/sites/default/files/images/bikes/keybike/byb/TN-byb-folding-stop-motion.gif) ![BYB: ultra slim folding bike](https://www.ternbicycles.com/sites/default/files/images/bikes/keybike/byb/TN-byb-g1-slimfold.jpg) The BYB is 30% smaller than traditional 20” folding bikes, and folds small and slim enough to fit into any narrow space such as behind doors or in lockers for handy, worry-free storage. ![BYB ultra compact folding bike - urban](https://www.ternbicycles.com/sites/default/files/2023-04/byb-urban.jpg) With limited apartment space no longer an issue for the small, slim BYB, the question now is what you want to get done with your bike. The BYB S11 and P8 are geared towards urban intermodal commuters who could use a little extra help when weaving through busy transit stations with their bike, while the BYB P10 is a lighter, sportier option for those who want to maximize their riding experience within precious free time. ![BYB ultra compact folding bike - sporty](https://www.ternbicycles.com/sites/default/files/2023-04/byb-sporty.jpg) The BYB is designed for commuting, but doesn’t just stop there. It also lets you bring your stuff, whether that’s a change of clothes, workout gear, or your laptop bag. Plus, the Metro Transit Rack on the BYB S11 and P8 further provides you options aplenty—add panniers, bags, racks, and baskets from Ortlieb and KlickFix to customize your ride. ![BYB: Carry More on Your Folding Bike](https://www.ternbicycles.com/sites/default/files/images/bikes/keybike/byb/TN-byb-s11-carrymore.gif) ![BYB: Multimodal commuter](https://www.ternbicycles.com/sites/default/files/2023-04/byb-mixitup.jpg) The BYB is perfect for mixed-mode commuters who do a stretch of their daily journey on a train or bus, or might grab a taxi home on a rainy day. Folded, the BYB fits anywhere so all your transport options are always open. ![BYB: Ready to roll folding bike](https://www.ternbicycles.com/sites/default/files/images/bikes/keybike/byb/TN-byb-g1-readytoroll.jpg) When equipped with the Metro Transit Rack, the folded BYB stands upright with one of the smallest footprints of any folding bike—and the rack’s built-in spinner wheels let you trolley the compactly folded bike through busy transit stations and onto crowded trains and buses with one hand while the other holds your coffee. The best things in life are shared, including your folding bike. The BYB has a low-step frame design and resizes in seconds—no tools required—to fit riders between 147 and 195 cm (4’10” – 6’5”), so you can share the bike with anyone in your family. ![BYB: Fits the Entire Fmaily](https://www.ternbicycles.com/sites/default/files/images/bikes/keybike/byb/TN-byb-g1-onesize.png) The new BYB P10 includes everything that makes the BYB tons of fun to ride, while trading in commuter-focused features like the fenders, rear rack, and chainguard for a lighter, sportier bike. But make no mistake—it’s just as compact and ready to accompany you on all your free-time adventures. ![BYB: Folding bike](https://www.ternbicycles.com/sites/default/files/2023-05/TN-photo-BYB_P10-00-satin-red-web.jpg) ![BYB: A folding bike for the weekend warrior](https://www.ternbicycles.com/sites/default/files/2023-04/byb-weekendwarrior.jpg) No matter how small or fast a bike folds, it needs to be a bike you want to ride in your hard-earned free time. The BYB champions the weekend warrior in you with a frame engineered for stiffness, 20” wheels, and performance components. All that’s needed is the desire to get out and ride\! ![BYB: How to Store a Folding Bike](https://www.ternbicycles.com/sites/default/files/images/bikes/keybike/byb/TN-byb-storage-animation.gif) Taking your bike on vacation? With accessories like the lightweight PopCover and padded Stow Bag designed for storing and transporting the BYB, you can go from riding to packed bike in 60 seconds. Even air travel is made a whole lot simpler: just pop the folded BYB into the AirPorter Slim suitcase—no disassembly required. ![BYB in an Airporter Slim](https://www.ternbicycles.com/sites/default/files/images/bikes/keybike/byb/TN-byb-airporterslim-airport.jpg) ![BYB-trifold](https://www.ternbicycles.com/sites/default/files/images/bikes/keybike/byb/TN-byb-g1-tech-trifold.jpg) TriFold technology is a patented new way to fold a bike small while delivering a quality ride. ![BYB-TFL-joint](https://www.ternbicycles.com/sites/default/files/images/bikes/keybike/byb/TN-byb-g1-tech-tfl.jpg) With an organically curved form optimized for strength, the TFL Joint is our most advanced yet and includes a number of critical new technologies. ![BYB-physis-rf](https://www.ternbicycles.com/sites/default/files/images/bikes/keybike/byb/TN-byb-g1-tech-physis-rf.jpg) Next to the frame, the Physis RF—our new 3D-forged handlepost—is the most important component contributing to the BYB’s stiff and responsive ride. ![BYB-andros](https://www.ternbicycles.com/sites/default/files/images/bikes/keybike/byb/TN-byb-g1-tech-andros.jpg) The Andros is our tool-free adjustable stem—it lets you adjust your riding position by setting your handlebars exactly where you want. ![BYB-metro-transit](https://www.ternbicycles.com/sites/default/files/images/bikes/keybike/byb/TN-byb-g1-tech-metro-transit.jpg) Roll the BYB like a spinner suitcase and easily maneuver the folded bike in crowded rail or bus stations. The Metro Transit Rack carries up to 20 kg (44 lb) and allows the BYB to stand vertically. Equipped on the BYB S11 and BYB P8. ![BYB-anchor-bolt](https://www.ternbicycles.com/sites/default/files/images/bikes/keybike/byb/TN-byb-g1-tech-anchor-bolt.jpg) Securely locks the sections of the BYB together when rolling or carrying the bike. Depress the lever and the clever release mechanism ejects the Anchor Bolt, making it easier to unfold. ![BYB-GSDna](https://www.ternbicycles.com/sites/default/files/images/bikes/keybike/byb/TN-byb-g1-tech-gsdna.jpg) The BYB inherits important technology—DoubleDeck frame design and the burly trapezoidal tubing—from the Tern GSD, ensuring extra stiffness and durability. ![BYB-combo-mount](https://www.ternbicycles.com/sites/default/files/images/bikes/keybike/byb/TN-byb-g1-tech-combo-mount.jpg) The same robust mount found on our cargo-focused GSD. The Combo Mount lets you install a variety of different racks, bags, and baskets to your BYB so you can also bring your stuff. ![BYB-kinetixProXWheels](https://www.ternbicycles.com/sites/default/files/images/bikes/keybike/byb/TN-byb-g1-tech-KxPro-wheel.jpg) Light, fast, and strong, Kinetix Pro and Pro X Wheels are hand-built with custom hubs and feature Rolf® Paired Spoke Technology. ![BYB-tfl](https://www.ternbicycles.com/sites/default/files/images/bikes/keybike/byb/TN-byb-g1-tfl2.jpg) Close the lever and a metal deadbolt slides smoothly into place, locking the hinge. Once you close the TFL, it stays locked in place. Ensures that your properly adjusted lever always stays at the proper tension, even after thousands of cycles of folding and unfolding. ![BYB-tfl](https://www.ternbicycles.com/sites/default/files/images/bikes/keybike/byb/TN-byb-g1-tfl1.jpg) Whereas most other folding bikes weld a simple tube to a plate, the TFL Joint features precision-machined inserts at the tube junction, ensuring more consistent welding and more material at the most highly stressed areas. Sliding bearings between the moving parts make sure that the folding action is always smooth and friction-free. These bearings are serviceable so if after a few years of hard use the bearings have worn down, your dealer can easily swap them out to refresh your bike.
