For a long time, the rule for e-bikes was simple: if you wanted more power, you had to accept more bulk. Full-power became synonymous with heavy.

We didn’t want to dial back the motor; we wanted to change how a high-performance e-bike actually feels under you. The Alterra is our answer. It packs a massive 130Nm of torque (150Nm in boost) and a long-range 800Wh battery into a silhouette that looks—and rides—like a traditional trail bike.

This isn’t just a frame adapted to a motor. We designed this carbon platform in-house from scratch around the new Avinox M2 and M2S systems. Our goal was simple: give you all the power, with none of the e-bike penalties.

The Alterra starts at 20.5kg—defying the bulk you’d normally expect from the numbers. It’s designed for massive days in the saddle while remaining light and responsive enough to feel natural underneath you. It’s simply more bike, and less machine.

A Different Approach to Suspension

We used a four-bar suspension design with an inverted linkage. Why? It’s not for the sake of doing something different, but because it solves real packaging challenges. It keeps the centre of gravity low, shock neatly tucked away and clears out the front triangle so you can actually fit a full-size water bottle. Because even on an e-bike, that still matters.
