Trek Powerfly 5 Electric Mountain Bike 2020
The Trek Powerfly 5 Electric Mountain Bike is ideal for anyone who wishes to increase the distance, speed or ease at which they can explore off-road. The 250W Bosch Performance CX motor and 500Wh battery can offer between 60% and 340% assistance depending on the mode selected, whilst the battery itself is easy to remove from the bike for charging inside the house.
SRAM’s 12-speed, single-ring SX Eagle shifters and derailleur are simple and intuitive to use, giving quick access to the entire range of the cassette. Mud and rain hold no fear for the Tektro HD-M275 hydraulic disc brakes, which bite through any dirt to help maintain control and confidence, as does the 120mm travel RockShox Recon RL suspension fork. Traction is provided by Bontrager XR3 Team Issue 2.35” tyres which are ready to be set up tubeless if so desired, for the benefits of extra grip, puncture resistance and comfort.
