Trek Powerfly Sport 7 Electric Mountain Bike 2020

The Trek Powerfly Sport 7 Electric Mountain Bike assists your pedalling with a 250 watt motor so you can set out on an adventure with no worries about gradient or difficulty.

The strong aluminium frame will withstand the rigours of trail riding, while the Schwalbe tyres provide excellent off-road grip. This is a versatile option with a 12-speed gearset that has a wide range for riding up the steepest climbs and powering along flat sections.

Front suspension in the SR Suntour fork softens your ride with 100mm of plush suspension. The four-piston Shimano hydraulic disc brakes provide all the stopping power you'll ever need, and the 625 Wh battery is engineered for long adventures.


  • The new, better-than-ever Bosch motor is smaller, lighter and more efficient. It feels more natural while you’re pedalling, and has less drag when you’re not
  • 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
  • It comes equipped with lights, mudguards and a rear rack so you're ready to ride right from the start
  • The Purion controller has Walk Assist and an intelligent eMTB mode that automatically delivers the right amount of power based on your terrain
  • The size S frame features a curved top tube that makes standing over the bike easier. Plus, Smart Wheel Sizing means you'll get the fastest wheel that fits – 29˝ wheels on larger frames, 27.5˝ wheels on smaller frames
