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.

- The Purion controller has Walk Assist and an intelligent eMTB mode that automatically delivers the right amount of power based on your terrain
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.
This unique protection shield is lightweight yet robust, and protects the motor from rocks, logs and other trail debris.
Control Freak cable management
The lightest, quietest, most versatile cable management system allows any combination of shift, brake, lockout and dropper post lines to be routed through the frame for clean looks and the ultimate custom set-up.
Rear kickstand mount
Chainstay mounts make it easy to install a rear kickstand that stays out of your way and supports bikes of all sizes. No more laying or leaning.
