Introducing the 2020 Powerfly 4 from TREK, the perfect e-bike solution for those wanting to expand their boundaries and achieve bigger trail adventures in a cost-effective way. A powerful combination of ultra-dependable parts and state-of-the-art technology, Powerfly 4 boasts an impressive 9-speed Shimano drive train, an unbeatable SR Suntour fork, and a high-performance Bosch Performance CX motor.

The heart of the Powerfly 4 is the user-friendly Removable Integrated Battery (RIB) system, fully encased in the frame for optimum protection yet easily removable without tools. The bike's lightweight and durable Alpha Platinum Aluminium frame further encases a long-range 500 Wh battery, adding a sleek look to the sturdy build. No distance is too far to conquer with Powerfly 4!

The bike features the intelligently designed Purion controller from Bosch which is equipped with a Walk Assist and an intelligent eMTB mode. This automatically supplies the ideal power based on your terrain. For charging convenience on or off the bike, an external charging port is provided.

Truly embodying TREK's trail heritage, the Powerfly 4 is equipped with top-end mountain bike technology developed from decades of innovation. In addition, the Smart Wheel Sizing ensures you get the fastest wheel fitting – 29? wheels for larger frames, and 27.5? wheels for the smaller ones.

Last but not least, saddle height is no longer a concern, thanks to TREK's thoughtfully designed frame sizes. S frames feature a top tube that dips down near the seat tube, allowing shorter riders to straddle their bikes with ease. In contrast, taller riders will enjoy a straight top tube on their M and ML frames, eliminating standover height issues.

With Powerfly 4, not only do you get the best of trail adventures, but also an ideal companion for commuting and leisurely rides. Set your sights on those uncharted terrains, Powerfly 4 is here for you.
