The Dirtlab Paratu CP Frame: A revolutionary e-bike frame kit with our latest G-Volve geometry and K-Volve kinematics, S-Volve sizing & fitted with the new Maxon Bikedrive Air S engine system for more power and range:
-
- G-Volve geometry is long, not too low, and slack. A 63.5-degree Head angle paired with a 77.8 seat tube angle.
- K-Volve kinematics here we switched from traditional Horst link to a concentric pivot, ruling out brake chatter disturbances to optimize the bottomless feel we are known for. low position when you use 29" F&R, High when you want a mullet setup 29F 27.5R.
- S-Volve sizing has become even better, as each frame now offers sizes within its range. We utilize a RA (Reach Adjust) headset system, allowing you to start in the 0 position, travel down your fork 10mm and use the shorter -5 position, or fork up 10mm and use the longer +5 position. The same thing works for people who are between our sizes, they can use the longer frame and start short or the smaller frame and start long.
- Driven by the new Maxon Bikedrive AIR S drive system: 88Nm, 650W, 400Wh internal battery, and an optional 250Wh. range extender.

Collaboration with Maxon: From 2020 to 2022, we worked closely with Maxon to integrate and refine the frame and engine system, ensuring a top-notch e-bike that rides like a dream. This resulted in the Maxon Bikedrive Air systems a 2x you system. Since then, the market has evolved, and more power was needed, so we embarked on the second phase of the Air S system, which resulted in increased power and range. We maintained the original smoothness and almost zero drag feeling in the engine, meaning that you can ride it analog if you switch off the modes, so the gears retract from the driveshaft.
