Trek Powerfly 5 Electric Mountain Bike 2019

Whether commuting or riding out on the trails, the Trek Powerfly 5 Electric Mountain Bike is the ideal companion. The 500 Wh Bosch CX battery gives great range and electrical assistance up to 25kph, allowing for longer rides, tougher climbs or maybe just a more pleasurable commute. The motor can be set to provide four different levels of assistance from the Purion controller, or it can be put in eMTB mode which will automatically adjust the assistance level to match the terrain, balancing power and battery life for optimal effectiveness.

The Shimano 10-42 tooth 10-speed cassette provides a very wide range of ratios when coupled with the 15 tooth front chainring, allowing plenty of options for steep hills and flat roads alike whilst the Shimano MT200 hydraulic discs give powerful, reliable stopping power in all weathers. The Trek Alpha Platinum Aluminium frame has both rack mounts and internal wiring for lights making it a very practical and versatile option.

Please note: Size 15.5” uses 27.5” wheels, sizes 17.5” and above use 29” wheels
