Powerfly LT 4 is an electric mountain bike with long travel front and rear suspension for especially technical terrain. It's made for real-deal mountain bikers who get rowdy on rugged trails with 150 mm of travel, a 160 mm fork, mid-fat 27.5+ tyres, a powerful Bosch motor that helps you sustain speeds of up to 15.5 mph and a durable trail bike spec.
It's right for you if...
Standard suspension doesn't cut it for the trails you ride. You're most likely to be found on technical trails with big drops and hits, so your e-MTB needs longer travel, a durable parts spec and a pedal-assist system that can keep up.
The tech you get
A durable Alpha Aluminium frame, a semi-integrated 500 Wh battery, a Bosch Performance CX motor and a Purion controller. Plus, 150 mm rear travel, a 160 mm SR Suntour Aion 35 fork, mid-fat 27.5+ tyres for traction and stability, a dropper post, 10-speed Shimano drivetrain and 4-piston hydraulic brakes for extra stopping power.
The final word
With Powerfly LT 4, you're getting a great frame with a powerful Bosch system that will take your riding to places that you've only imagined. But it's the longer travel suspension and mid-fat 27.5+ tyres that give Powerfly LT 4 extra capability on rugged terrain, sketchy trails and steep descents.
Why you'll love it
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 rides like a mountain bike because it is one: it has the same frame and suspension tech that we've refined in our decades-long trail heritage
The long-range battery is secure while you ride and easy to remove for charging in any household electrical socket
