Trek Powerfly LT 4 G2 Electric Mountain Bike 2020
The Trek Powerfly LT 4 G2 Electric Mountain Bike will take you places you've never been before, with a smile on your face. The trails that seemed off-limits are open now, thanks to the powerful 250 Watt Bosch motor. Power up the toughest inclines and enjoy the descent with the dual suspension soaking up the bumps and ruts.
Rolling on a set of purpose-built wheels, you'll enjoy the reliable Bontrager alloy hubs and lightweight Alex MD35 clincher rims. The gearset is specced to provide uphill support, so you can ride any trail or singletrack, whatever the gradient.
- Longer travel suspension and 27.5+ mid-fat tyres are the perfect combination for traction, stability and capability on rough trails
- For e-MTB, full suspension is a game-changer: It soaks up rugged terrain, so you can ride the Bosch pedal-assist system to its full potential
- It's equipped with an external charging port for easy charging on or off the bike
- It rides like a mountain bike because it is one: it has the same frame and suspension tech that Trek refined in their trail heritage
- The Purion controller has Walk Assist and an intelligent eMTB mode that automatically delivers the right amount of power based on your terrain
