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 Platinum Aluminium frame that fully encases a long-range 500 Wh battery, a powerful Bosch Performance CX drive system that helps you sustain speeds of up to 25 km/h, and an ergonomic Purion controller. Plus, 150 mm of front and rear suspension with an SR Suntour Zeron fork and RockShox Deluxe RL shock, 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 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.

favorite_borderWhy you'll love it

  1. Longer travel suspension and 27.5+ mid-fat tyres are the perfect combination for traction, stability and capability on rough trails
  2. 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
  3. It's equipped with an external charging port for easy charging on or off the bike
  4. 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
  5. The Purion controller has Walk Assist and an intelligent eMTB mode that automatically delivers the right amount of power based on your terrain


Features

Bosch Performance Line CX

Bosch's Performance Line CX motor is made specifically for off-road use with more torque and power for better acceleration. The intelligent eMTB mode automatically adjusts the amount of assist to match the terrain. It's a set-and-forget mode that delivers just the right amount of power. You get optimum control, traction and battery life so you can focus on enjoying the ride.

Removable Integrated Battery

RIB is a one-piece battery and cover with a built-in handle that can easily be removed and re-installed in the frame with no tools and no hassle. It’s the most convenient way to remove your battery for transport, security or just easier charging.
