About The Powerfly:

The Powerfly is Trek's best value electric bike and a firm favourite for mountain bikers, commuters and anyone who wants to ride a bit further and a bit faster.

The new Powerfly is built around the Removeable Integrated Battery (RIB), a clever system that hides the 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 250W 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.

The star of this show though is the Bosch motor. This efficient motor amplifies your pedalling input, so when you start to pedal, the motor kicks in to take some of the strain, thus allowing you to travel further and faster. The latest technology ensures power is delivered in a controlled fashion so you get a ride that feels natural. 4 power modes, controlled via the neat handlebar-mounted computer, means 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 built 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. However, the medium tread pattern works well on the road too, rolling easily and providing grip when you need it. A wide ranging drivetrain is easy to operate, smooth and reliable - in other words, it works so well you won't even notice it.

The Powerfly is finished with a stylish finishing kit including wide handlebars and comfortable saddle, and powerful hydraulic disc brakes with large diameter rotors which are well suited to keeping the Powerfly under control, even on loose terrain.

If you're looking for an e-bike for off-road and all -oads use, the Powerfly should be top of your list. The clever design makes it easy and practical to live with day-to-day yet its 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.

Product Code: BIHDSPAL0074

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.
  • The Bosch electric system is a massive leap forward in electric motors. A good range with 500WH battery and plenty of power make this a real game-changer in the e-bike world.
  • Shimano 1x10 speed drivetrain is simple to operate and supe reliable. It's another part of this bike that just works well without any fuss.
  • Powerful hydraulic disc brakes and large rotors ensure you can stay in full control even in adverse weather.
  • 29" Bontrager Line Comp wheels 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.
  • An all round e-bike, bang-up-to-date and ready for anything

Please note: Smaller frames have a top tube that dips down as it approaches the seat tube. This design makes for a lower standover height which is good for shorter riders. The larger frames have a straight top tube.

A Note On Wheelsizes:

  • Like most of Trek's mountain bikes, size XS & S bikes come with 27.5" wheels while size M & larger come with 29" wheels. This ensures each frame size is optimised to better fit the rider.
