About The Powerfly:

Totally re-designed for 2020, the Trek Powerfly has really come of age and become the go-to e-bike for all round mountain biking and general riding.

Let's start with the frame. The new Powerfly is built around the Removeable Integrated Battery (RIB), a clever system that hides a 500WH Bosch battery in the downtube. It's so neat, you'll barely notice this bike has added power. The frame itself encases the battery and motor using Trek's Alpha Platinum aluminium - a strong and light material - with sleek features like internal cable routing and armour around high impact areas. With a modern geometry and reduced offset fork, the handling is spot on for general off road riding and allows you to ride hard on all but the toughest trails. This women's model features a curved top tube for greater standover height and comfort.

The star of this show though is the Bosch motor. 250W of extra power really take the sting out of climbs and allow you to travel further and in more comfort. 4 power modes ensure you can prioritise speed or distance to best meet your needs. The battery can be charged in the bike or easily removed for convenience. With Bosch's legendary reliability and support, this is a brilliant design and one that is designed for many seasons of hard use.

Up front a 120mm suspension fork kees your wheel tracking where you want it and smooths out the terrain. Chunky 2.3" tyres really hold momentum over rough ground and, due to the extra volume and width, provide increased grip and traction. The women's Powerfly has different sized wheel to match the size of frame - S & XS get 27.5" wheels while M & L get 29". This creates a more proportioned fit for each rider and creates a better handling bike for each size.

The Powerfly is finished with a stylish finishing kit and powerful hydraulic disc brakes which are well suited to keeping the Powerfly under control, even on loose terrain. A wide ranging single-ring drivetrain is easy to operate, smooth and reliable - in other words, it works so well you won't even notice it.

If you're looking for an e-bike for off road and all roads use, the Powerfly should be top of your list. It's clever design makes it easy to live with day-by-day yet it's performance both on and off road is what separates it from the rest. A true all rounder for the rider who wants electric assistance in a reliable and fun package.

Powerfly 4 Features:

  • Aluminium frame with integrated battery and motor are designed for off road and all road riding, as well as every day practicality.
  • Women's design makes for more room for standiing over the bike.
  • The Bosch electric system provides smooth and consistent power while the large battery means you get a long run time. It's a brilliant performer for all round riding.
  • The wide ranging Shimano Altus drivetrain is simple to operate, durable and offers enough gear choice for almost any terrain.
  • Hydraulic disc brakes work well in all conditions and ensure you have control at all times.
  • Bontrager rims are strong and light, and coupled with the 2.3" Bontrager XR3 tyres roll quickly and hold momentum. It's a great all round combo for mixed riding.
  • Smart Wheel Sizing means getting the right diameter wheel to suit your height. S & XS frames get 27.5" while M & L get 29" so the bike is better proportioned for each rider.
  •  An all round e-bike, ready for anything
