Full Carbon Integrated Design
The SIERRA's full carbon frame is manufactured using state-of-the-art aerospace technologies and integrates its battery, motor, wires, cables and electrical components perfectly. Its lightweight carbon frame allows for great manoeuvrability, enhanced range and optimal comfort.
Powerful BOFEILI Mid-Motor
With over 500W peak power, the SIERRA's high-performance torque-sensing BOFEILI 250W mid-motor feels exactly how much pressure you are applying to the pedals and reacts accordingly. It provides you with so much power that you feel like a record-breaking Olympic athlete.
We assemble the SIERRA's removable Lithium-ion battery with the best cells available on the market, the same as those used in the Tesla Model S. The result is an incredibly lightweight and compact 375Wh (or 500Wh) battery.
Onboard Computer and Backlit LCD Display
See how fast you're going, how far you've ridden, your live battery capacity, average velocity and current power consumption. Choose between 5 pedal assist power modes: transform your SIERRA to a classic mountain bike or a full power all-terrain machine at the touch of a button. The walk assist mode gets you a solid initial boost of 6km/h and makes your high gear starts smoother.
Hydraulic Disk Brakes
We equipped the ultimate mountain ebike with the ultimate stopping system. Shimano M315 Hydraulic Disk Brakes provide long-lasting and powerful braking for the most agressive riders in the most extreme conditions.
18 Speeds Shimano Gears
The SIERRA's powerful mid-motor is connected to 18 Shimano gears distributed through 2 Shimano chainrings and 9-speed Shimano gears. This leads to outstanding torque control, range, speed and hill climbing.
