Product Details

Powerfly FS 4 is a full suspension electric mountain bike built to tackle rugged trail adventures.

The plush suspension set-up soaks up rough terrain, and the powerful Bosch electric drive system boosts your capacity to crush climbs and mile after mile of singletrack.

A durable aluminium frame that fully encases a long-range 500 Wh battery, a powerful Bosch Performance CX (250 Wh, 75 Nm) motor that helps you sustain speeds of up to 32 km/h and an ergonomic Purion controller. Plus, an SR Suntour suspension fork, 100 mm of rear travel, a 10-speed Shimano drive train, powerful hydraulic disc brakes and a dropper post

Features
  • For e-MTB, full suspension is a game-changer: it soaks up rugged terrain, so you can ride the Bosch pedal-assist system to its full potential
  • 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 to remove the battery without tools and lets you mount a water bottle cage – even on full suspension e-MTBs
  • The dropper post lets you lower your saddle on the fly so it's out of the way on descents
  • The Purion controller has Walk Assist and an intelligent eMTB mode that automatically delivers the right amount of power based on your terrain
  • The size S frame features a curved top tube that makes standing over the bike easier. Plus, Smart Wheel Sizing means you'll get the fastest wheel that fits – 29˝ wheels on larger frames, 27.5˝ wheels on smaller frames

About Trek
From small beginnings [Trek was started in a barn in Waterloo, Wisconsin, in 1976] to becoming a giant in the industry. Their range of products covers every aspect of cycling, from kids bikes to competitive race machines, commuter bikes to high-tech e-bikes.
