EX DEMO ELECTRIC BIKE. ONLY DONE 11 MILES. FOR FURTHER DETAILS PLEASE EMAIL sales@allterraincycles.co.uk 

eBikes by their very nature can in the future require aftermarket updates and support. This cannot be supplied by All Terrain Cycles at distance; if required the work would have to be obtained from your local Brand Dealership, possibly at extra cost to yourself.

Your eBike will be delivered built, set up and updated.

Minimum personal assembly is required.

Powerfly 4 is our most affordable electric mountain bike. It's built with parts that hold up, like a smooth-shifting Shimano drive train, and a powerful Bosch motor. Plus, it features our user-friendly Removable Integrated Battery (RIB) system that's fully encased in the frame yet doesn't require tools for removal. This bike expands your boundaries and lets you travel to destinations that you never thought you'd reach on a mountain bike.

Key Features:

• 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 remove the battery without tools and lets you mount a water bottle cage
• This bike expands boundaries: the top-notch Bosch system is equally suited to commuting, recreation and a ridiculously fun time on the trails
• The Purion controller has Walk Assist and an intelligent eMTB mode that automatically delivers the right amount of power based on your terrain
• It's equipped with an external charging port for easy charging on or off the bike
• You can boost your Powerfly’s utility by adding a rack and mudguards, plus built-in wiring lets you easily install lights powered by the motor
