One of our team at our Colchester Revolution Store (Thanks Dano!) recently had a chance to get hands on with Trek's Powerfly 4, he let us have his initial thoughts, we wanted to share them with you:

“First thoughts are this is a stunning looking bike. My colour of choice would be the bright orange, although it is a close run with the grey and black.
625 or 500 Watt battery with some of the colours, again choices..
Plenty of attention to detail, quality finish, through axle etc. Love the way the battery sits in the frame. Very neat.
The ride is smooth, with the power just flowing in from the CX Bosch motor. I forgot it was an Ebike during the ride. Just enjoyed the experience.
The bike is ready to go, but mudguards, rack can be easily fitted and a wiring loom is ready if lights are required.
Spec is great, but plenty of options to upgrade if you like to make it personal.


Powerfly 4 is an affordable electric mountain bike. This e-MTB is built with parts that hold up, like a dependable 9-speed Shimano drivetrain, a 100 mm suspension fork, fast-rolling wheels and a Bosch Performance CX motor that assists up to 15.5 mph. This bike expands your boundaries and lets you travel to destinations that you never thought you'd reach on a mountain bike.

  • Trek's Removable Integrated Battery (RIB) system looks great and is super user-friendly: it fully hides the battery in the frame for protection, makes it easy remove the battery without tools and lets you mount a water bottle cage
  • This bike expands boundaries: the top-notch Bosch system is equally suited to commuting, recreation and a ridiculously fun time on the trails
  • The Purion controller has Walk Assist and an intelligent eMTB mode that automatically delivers the right amount of power based on your terrain
  • It's equipped with an external charging port for easy charging on or off the bike
