Trek Powerfly+ 4 Electric Mountain Bike – Available in Small, Medium & Large

Looking for a nearly-new electric mountain bike that delivers outstanding performance without the premium price tag? This Trek Powerfly+ 4 is the perfect choice.

Less than a year old and with very low mileage, these bikes are in great condition and ready for their next adventures. Whether you're tackling challenging trail centres, exploring the South Downs, commuting in comfort or simply riding further than ever before, the Powerfly+ 4 is built to do it all.

Designed around a strong and confidence-inspiring aluminium frame, the Powerfly+ 4 combines capable trail handling with everyday practicality. Up front, the SR Suntour suspension fork smooths out rough terrain, while Shimano's dependable 10-speed CUES drivetrain delivers crisp, reliable shifting mile after mile.

At the heart of the bike is the latest Bosch Performance Line CX motor, providing effortless assistance on steep climbs and technical trails while still feeling natural and responsive. Using the Bosch eBike Flow app, you can even customise the motor's performance, increasing output to an impressive 100 Nm of torque and 750 watts of peak power to suit your riding style.

The cleverly designed RIB 2.0 removable integrated battery is easy to remove for charging, transport or storage, while remaining secure and virtually rattle-free when you're out on the trail.
