Highlights Of This Electric Bike
Uses the Bosch eBike System
With a re-worked frame and frame geometry, the updated Vektron is now even better. The cockpit is longer for improved comfort for taller riders. The frame has been designed with additional forged and machined elements for additional strength without extra weight. The battery now reclines backward, keeping the center of gravity as low as possible for superior handling. And the new design allows the Vektron to stand up vertically when folded, making it even easier to roll around.
- Fits easily on buses and subways for electric multi-modal commuting
- Resizes in seconds to fit riders 4’10” – 6’5” so a single bike can be shared by the family
- Stores under a desk for convenient theft protection; no need to bring a heavy lock
- Stash a pair in the trunk of a car for weekend getaways
- German-engineered Bosch Active electric drivetrain—the industry leader in electric bike technology
- T-Tuned™ geometry for a full-sized ride and comfort
- Valo™ lighting system, with 150 lumens of power, for 24-hour visibility
