Ride it, Fold it, Go Further
The Vektron is a best-in-class electric bike that folds in 10 seconds to go on trains, in cars, and under desks. Shorten distances and flatten the hills on your commute, or put a couple of Vektrons in the trunk of your car on your next trip, so you can explore further.
The Tern Vektron combines a serious folding commuter bike and the more powerful Bosch Active Line Plus drive system to create a bike that customers have been asking for: a folding electric bike with ample power and a ride quality that defies logic.
The Vektron Q9 brings the full-size e-bike qualities to the table in an e-folder. While it weighs less than 50 pounds and folds up to roughly the size of a skinny end table in seconds, the Tern Vektron Q9 is versatile enough to carry riders up to 6 feet 3 inches with everything you need to get to work.
By configuring the Vektron Q9 with a mid-drive motor, Tern’s designers have optimised weight distribution, giving this folding e-bike fantastically balanced agility.
Tern has developed a great folding bike for those looking for a compact and practical bike for everyday use.
Features:
- Upgraded to the Bosch Active Line Plus electric drivetrain for up to 270% assistance and 50 Nm of torque
- Hydraulic disc brakes for all-weather stopping power
- Updated frame with a reclining battery for a lower center of gravity and better ride
- Frame passed strict European safety standards for pedal-assist e-bikes, having been certified as EN15194-compliant by EFBE Prüftechnik
- Integrated Atlas V Rack™ works seamlessly with Thule Yepp Maxi and Dash® RM child seats—no adapters needed
- Resizes in seconds to fit riders 147 – 195 cm (4’10” – 6’5”) so a single bike can be shared by the family
One Size Fits Most
The Vektron 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.
