The Trek Powerfly+ 4 Gen 5 is a dependable electric hardtail designed for riders who want the confidence of a full-power Bosch system without pushing into premium territory. At its heart is the Bosch Performance Line CX motor, delivering up to 85Nm of torque for tackling steep climbs and headwinds with ease. Controlled by the compact Purion 200 display, this smart system lets you fine-tune support modes and integrate app-based features for added ride customisation.
The 600Wh Bosch PowerTube battery sits securely in Trek’s RIB 2.0 (Removable Integrated Battery) system, no tools required for removal and is rattle-free when riding. There’s even PowerMore booster battery compatibility, or you can upgrade to 800Wh if you're planning to go further afield.
The Alpha Platinum Aluminium frame is tough and thoughtfully designed, with guided internal cable routing, Motor Armour, and mounting points for lights, a kickstand, rack, or mudguards, making it as suitable for weekday commutes as it is for weekend trail rides. The frame's geometry gives a confident feel on loose ground while keeping things comfortable on longer outings.
Up front, the SR Suntour XCR 34 fork with 120mm of travel uses an air spring and hydraulic lockout to provide bump absorption on rocky tracks and smoother handling when cruising fireroads. The Shimano CUES 10-speed drivetrain is built around the durable LINKGLIDE system, offering long-lasting, reliable shifting and a wide 11–48T cassette for mixed elevation terrain.
Stopping is handled by Tektro hydraulic disc brakes, which offer solid power and modulation for year-round control. The 29" Bontrager wheels and 2.4" XT3 Comp tyres give plenty of traction and cushioning, whether you’re climbing forest tracks or rolling along canal paths.
If you’re looking for a value-packed e-MTB that blends trail-ready performance with everyday versatility, the Powerfly+ 4 Gen 5 is an excellent all-rounder. Confident, capable, and ready to ride wherever your next route takes you.
