Trek Powerfly 7 Women's 27.5" E-Mountain Bike 2019

Trek's Powerfly 7 Women's 27.5" E-Mountain Bike is a performance trail bike with the added benefit of a Bosch Performance CX motor to help you up the climbs and make your riding even more enjoyable. The long-range Bosch PowerTube 500Wh battery has a RIB (Removable Integrated Battery) design that makes it easy to install, remove, transport and charge.

The frame is constructed from Alpha Platinum aluminium that's strong, light and durable, and the Women's Specific Design means that the geometry and finishing kit are all designed to provide better control, stability, power and comfort. With an Armour protection shield, the motor is well protected from damage caused by rocks and other trail debris.

A 1x Shimano drivetrain and hydraulic disc brakes offer plenty of range for climbing and descending, and no matter the conditions you can rest assured of powerful stopping. Rolling on Bontrager Kovee 23 wheels and XR3 Team issue tyres, your setup can easily be converted to tubeless for faster rolling and reduced punctures.


  • Alpha Platinum premium aluminium for strength and low weight
  • Trek's WSD (Women's Specific Design)
  • Bosch Performance CX for rugged off-road use, with a maximum torque of up to 75Nm
  • Trek's Removable Integrated Battery (RIB) system looks great and is super user-friendly; it fully hides the battery in the frame for protection, makes it easy to remove the battery without tools and lets you mount a water bottle cage
  • Bosch Purion display features a fully-functional speedometer with a backlit display, service interval indicator and battery range indicator
  • The dropper post upgrade makes Powerfly 7 even more capable
  • It rides like a trail bike because it is one: Powerfly is built according to Trek's trail heritage with mountain bike tech developed over decades of innovation
  • This bike expands boundaries: the Bosch system is equally suited to commuting, recreation and a ridiculously fun time on the trails
  • This bike is built for the long-haul: it comes with a 500 Wh battery, the longest-range available from Bosch
  • Motor Armour - Unique protection shield made of light but robust aluminium
  • Internally wired to accept additional lights
  • Mounts for racks
