About The Powerfly:

The Powerfly is Trek's most popular electric bike and a firm favourite for mountain bikers who want to ride further and faster.

The Powerfly is built around the Removeable Integrated Battery (RIB), a clever system that hides the 500WH Bosch battery in the downtube. 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 44mm 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 is the Bosch Performance CX motor that assists up to 25kmph. Combined with 500WH battery the range of the Powerfly is spot on for a day's riding while clever electronics mean that the power is delivered smoothly to mimic a natural ride. 4 power modes ensure you can prioritise speed or distance to best meet your needs, controlled by a neat colour-screen computer. 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 (80mm in XS) Suntour suspension fork keeps you in control and comfortable over rough ground. Wide 2.3" tyres are mated to Bontrager's proprietry wheelset, providing a stiff, strong and light wheelset that is ready for ultimate off-road performance. Gearing is taken care of by a 1x10 speed Shimano mix which has a wide range, light weight and great reliability.

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

The Powerfly 4 keeps a balance of fire road and light trail accessibility whilst keeping the cost affordable. If you're wanting even more off-road mountain bike capability with higher spec components, more gears and a dropper seat post, consider the Powerfly 7. But if you're after a reliable and quality set up that gets on off road and away into the countryside, then the Powerfly 4 is for you.

Product code: BIHDH4AL0053 | Colour: AZURE NAUTICAL NAVY

Powerfly 4 Features:

  • Aluminium Platinum frame with integrated battery and motor are designed for off road and all road riding, as well as every day practicality.
  • The Bosch Performance CX electric system is a massive leap forward in electric motors. A huge capacity 500WH battery and plenty of power make this a real game-changer in the e-bike world. 
  • SR Suntour fork with 80/120mm travel uses wide diameter stancions for pinpoint steering in rough terrain.
  • Shimano 1x10 speed drivetrain is light, slick and reliable.
  • Powerful hydraulic disc brakes and large 203mm rotors ensure you can stay in full control even in adverse weather.
  • 29" Bontrager wheels are strong and light, and coupled with the 2.3" Bontrager XR3 tyres roll quickly and hold momentum.
  • A proper electric mountain bike for regular off-road riding.

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.
