Season:2025

Brand:Trek

Adventure-ready electric mountain bike for all terrains.

The Powerfly+ 4 is an adventure-ready electric mountain bike that doesn't break the bank. It's designed for exploring anywhere from rugged commutes to light singletrack with a rugged aluminium frame, bump-smoothing suspension fork, and a powerful Bosch Performance Line CX motor that boosts you up and over steep climbs.

An Alpha Platinum Aluminium hardtail frame with an air-sprung SR Suntour suspension fork ensures durability and comfort. The bike features a powerful Bosch Performance Line CX motor (85 Nm, 250 W), with a 600 Wh Powertube RIB 2.0 removable integrated battery and Purion 200 controller. It also includes a durable Shimano Cues 10-speed drivetrain and Tektro hydraulic disc brakes for reliable stopping power.

The Powerfly+ delivers a full-assist ride that's as versatile as it is powerful. Bosch's Performance Line CX motor provides plenty of torque for steep climbs and is easy to control with the Purion 200 remote. The RIB 2.0 removable integrated battery is easy to remove for travel and storage, and it's virtually rattle-free while you ride.

Features:

  • Full-assist ride with versatile power.
  • Bosch Performance Line CX motor with 85 Nm torque.
  • RIB 2.0 removable integrated battery for easy travel.
  • Compatible with Bosch Powermore booster batteries.
  • Mounts for lights, mudguards, rear rack, and kickstand.
  • Bosch eBike Flow app for customization and tracking.
