A new era of urban mobility - TERN BYB
B ring You our B ike | exploring | every day | everywhere | on the train | to work | in the trunk | on the subway | on the flight.
A premium folding bike with an innovative folding concept and incredible handling characteristics. The folding bike world has been waiting for this little speedster.
Folds small, slim fit: 30% smaller than previous Tern 20-inch models. Slim enough to fit comfortably in lockers, closets, or tight spaces.
Small footprint: When folded, the BYB has a very small footprint. This makes it much easier to handle on crowded trains and buses or when navigating busy subway stations.
Ready to Roll: The BYB stands on its luggage rack, and thanks to the built-in spinner wheels, you can steer the bike with one hand and hold your coffee with the other.
Pop, Cover, Roll: Most folding bike covers are either too complicated or too time-consuming to use multiple times a day. The BYB is not only easy to fold and transport, it's also extremely easy to cover. Simply pull the PopCover over and you're ready to go.
Mix It Up: The BYB is designed for mixed-mode commuters who want to travel part of their daily journey by train or bus, or take a taxi home on a rainy day.
Bring your stuff: A commuter bike should allow you to carry your stuff, whether it's a change of clothes, workout gear, or your laptop bag. Add panniers, bags, racks, and baskets to customize your ride.
Theft insurance : When you lock your bike outside, do you look out the window every five minutes to check if it's still there? The BYB folds up small enough for you to bring it indoors and store it in your closet, behind the counter, or under your desk.
Share your ride: The best things in life are shared, including your commuter bike. The BYB features a low-step frame and adjusts in seconds—no tools required—to fit riders between 147 and 195 cm, so you can share the bike with everyone in your family.
Easy storage: Small apartments and commuter bikes don't usually mix. Great news! The sleek little BYB fits almost anywhere—behind doors, under desks, in your closet. In fact, the BYB fits perfectly with standard cabinets.
Ready to Go : Ever wished you could take your own bike on vacation? With the BYB, you can go from folded to packed in 60 seconds. Flying is much easier with the BYB. Quickly fold the bike and fit it into its own, specially designed AirPorter Slim suitcase—no disassembly required.
MORE HIGHLIGHTS:
TriFold Technology: TriFold technology is a new patented method for folding a bike even smaller while still ensuring a high-quality ride.
TFL Joint: With an organically designed shape optimized for strength, the TFL joint is Tern's most advanced joint yet and incorporates several relevant new technologies. The innovative folding principle of the two joints: one is responsible for folding halfway to the rear, the other for the front wheel and the front wheel. Priority: smooth, intuitive folding.
Physis RF: Besides the frame, the Physis RF – a new 3D-forged handlebar post – is the most important component that contributes to the BYB's stiff and responsive handling.
Adjustable Andros stem: Tool-free adjustment of the driving position.
Metro Transit Rack: Roll your BYB like a trolley and maneuver the bike in crowded train or bus stations. Allows the BYB to stand vertically.
Anchor Bolt: It securely locks the BYB frame halves together when you want to roll or carry the bike. Press the lever, and the clever release mechanism releases the anchor bolt, making unfolding easier.
DoubleDeck frame: The BYB inherits key technologies—twin-tube frame design and voluminous trapezoidal tubing—from the Tern GSD to provide additional rigidity and durability.
Combo Mount : The same robust mount found on the cargo-oriented GSD. The Combo Mount lets you attach a variety of different racks, mounts, bags, and baskets to your BYB, so you can carry all your essentials.
Kinetix Pro X wheels: The Kinetix Pro X wheels are light, fast, and strong. They feature custom hubs and Sapim Aero spokes with a straight-head, paired spoke design.
The final folding size, the secure cohesion of the folding package, the reliability and durability of all elements, the optimal accessories for many user applications, the driving fun factor: the TERN BYB impresses on all levels and leaves nothing to be desired!
