Description
Built to carry 2 kids plus groceries—or a whole lot of cargo—and featuring dual-battery technology that's ready to ride all day, the Tern GSD S10 electric bike just might be able to replace your car.
Features
- The same length as a regular bike, the GSD S10 is incredibly easy to own and use, thanks to space-saving features like FlatFold and Vertical Parking
- With FlatFold, the handlebar and stem fold down next to the frame, and the seat post telescopes all the way down, enabling the bike to fit in larger vehicles and tight spaces
- Regular bikes take up a lot of floor space, but the GSD S10 parks vertically, so it takes up about as much space as a potted plant—perfect for city apartments and elevators
- Bosch® Cargo Line Motor provides up to 85 Nm of torque and 400% support, making it easier to tackle big hills and ride with heavy loads
- Shimano Deore shifting with Deore Shadow+ rear derailleur offers crisp, reliable changes across the wide-range 10-speed cassette
- Adjustable cockpit comfortably fits riders 4'11" to 6'5" (150 to 195 cm)
- Super tough Atlas Lockstand™ automatically locks when engaged—just press a button on the handlebar to unlock
- Heavy-duty frame-integrated rear rack and integrated lower decks offer plenty of kid and cargo capacity—this bike handles up to a 440 lb. (200 kg) Maximum Gross Vehicle Weight
- Magura® MT5 eSTOP 4-piston hydraulic disc brakes deliver powerful and responsive braking in all conditions
- Always-on RearStop™ brake light helps you signal stops
- Integrated Abus® wheel lock is keyed-alike with the battery
- Upgraded Atlas wheels feature custom CNC-machined hubs for extra strength and durability
- Integrated Tern Valo direct head light provides 150 lumens (41 lux) to help you see and be seen
- Compatible with a wide range of cargo- and passenger-carrying accessories (not included)
- Fits up to 2 Thule® Yepp Maxi seats (not included) with no adapters needed
