Climb mountains while enjoying the scenery. Ride brilliant downhill routes while concentrating purely on the landscape. That's what the Overvolt AM 5.5 offers. It can cross mountains and redefine your limits. With 150 or 160 mm of clearance, you can tackle the most technical paths thanks to an electrical mountain bike developed with a centralised and lower centre of gravity. The result is a dream to ride and boundless pleasure.

All Mountain Supreme 5 aluminium frame

The OVV AM 5.5 frame is crafted from lightweight and rigid Supreme 5 aluminium. It has clearance of 150 mm thanks to the OST+ drivetrain which offers excellent traction sensitivity and comfort, and offsets the pumping effect for greater efficiency.

Yamaha system with PW-ST drive unit and integrated 500Wh battery

The Yamaha PW-ST drive unit has the benefit of 70 Nm of self-regulated power for controlled traction whatever the slope or pedalling torque. Its new difficulty-based automatic assistance management system is another plus. And the integrated 500 Wh battery in the frame will extend your playing field.

Lapierre 27.5 Alloy wheels and Maxxis "+" tubeless tyres

Specific electrically-assisted mountain bike wheels – Our Lapierre eAM+ Tubeless-compatible wheels are specially designed for electrically-assisted mountain bikes. The aluminium wheel rims were chosen for their reliability and reduced inertia. Their 27.5” diameter and 35 mm rim width are specific to wide 2.8 tyres for added comfort.
