A well styled, strong and capable e-bike

Stylish all-rounder. The Trek Powerfly 4 ebike is the entry level mountain bike in the Trek e-mountain range. It benefits from the deign and innovation invested in the Powerfly platform with the bonus of an especially designed hydroformed frame to integrate the Bosch Performance CX motor and 500Wh battery. To keep things easy to use and to ensure versatility Trek have ensured that the battery charging is easy to access and have included mounts for a rear rack. This model is also pre-wired to enable lights to be added should you wish.

A unique feature of the Powerfly 4 ebike model is the 148/110 boost wheels. Wider dropouts (110mm at front, 148mm at rear) offer the stiffness of a 27.5" wheel and the benefits of a 29" wheel.  Boost 148 at the back lets you run wider tyres and a larger chain ring without affecting balance and handling. Therefore, depending on the size of the rider you can run either 27.5" or 29" wheels. 

The Powerfly 4 ebike has a handy 100mm travel in its front suspension and runs on dependable 9-speed Shimano gearing system. Tektro hydraulic disc brakes provide reliable braking, and Trek's unique Motor Armour protects the motor from stone flicks and damage.
