The Goldilocks of Folding E-Bikes
This fourth-generation folding e-bike delivers what most compact electrics can't—a ride that feels like a real bike. With a rigid aluminum frame that minimizes flex, dialed-in geometry, and premium Bosch Smart System power, the Vektron P5i combines exceptional ride quality with true portability. The patented fold takes under 10 seconds, transforming it into a self-rolling package that fits under desks, stands upright in corners, or tucks into car trunks.
Show full description and specs
The P5i features a whisper-quiet Gates Carbon Drive belt paired with a Shimano Nexus 5-speed internal hub—no oily chains to worry about when carrying. Bosch's Performance Line motor delivers 75 Nm of torque with pedal-assist up to 20 mph, while the 545Wh PowerPack provides up to 75 miles of range. The adjustable cockpit resizes tool-free to fit riders from 4'10" to 6'5", making it genuinely versatile for the whole household.
