Trek Powerfly+ 4 Gen 5 (2025)

It's right for you if...

You think a weekend of cruising over miles of smooth singletrack and mountain trails sounds better with a big boost. You're looking for a capable e-MTB that's got plenty of power, parts you can count on and just enough suspension to keep you comfortable when things get a little rough.

The tech you get

An Alpha Platinum Aluminium hardtail frame with a RockShox Recon Silver RL fork with Solo Air spring and a Motion Control damper. A powerful Bosch Performance Line CX motor (85 Nm, 250 W), with an 800 Wh PowerTube RIB 2.0 removable integrated battery and Purion 200 controller. A 12-speed Shimano Deore and XT blend drivetrain, Tubeless Ready Bontrager wheels, a Bontrager Line dropper post, 4-piston Shimano hydraulic disc brakes and plenty of mounts for bags and racks.

The final word

Get ready to explore with the Powerfly+ 6. This confident electric hardtail gives you plenty of boost wherever you roll, with just enough suspension to smooth out rough trails, mounts for bags and racks, and a 12-speed drivetrain that delivers plenty of gears for all the ups and downs ahead of you.
