One frame. Your terrain.
From bike park to singletrack, the same CNC-machined platform is set up for how and where you ride.
See it change.
Pick travel, wheels, size and finish. The bike and its geometry update as you go.
152 to 200 mm, four configurations.
Every configuration is engineered with its own kinematics and geometry. When your riding changes, you change the setup. You keep the frame.

Raw Silver, clear e-coat. The machining is the finish.

Long and slack. Easy to lift and place.
Maxon Air S.
We chose the Air S for its natural pedalling feel, low weight and compact size. A smaller drive unit leaves us room to put the frame and suspension components where we want them.
- Torque
- 90 Nm
- Peak power
- 620 W
- Motor weight
- 2.0 kg
Adjust the assistance.
Choose between three support levels from the handlebar remote. Maxon's app lets you adjust how they respond: ask more of your legs, or use stronger support for the climb. In the film, Leo changes the settings and rides the same terrain to show the difference.
The Air S is quiet on the trail, with more motor sound as you ask it for more power. You can hear it working in the riding footage below.
Take more battery when you need it.
An optional 250 Wh range extender adds capacity for longer rides. Leave it off when you want to keep the bike lighter.

CNC-machined 7075 aluminium.
We machine the frame parts from 7075 aluminium and bond them using our own method. The pivot locations match our CAD model within ±0.05 mm.
