Ready to be released into the wild
Each part is CNC machined from 6061-T6 aluminum. The gearbox case and plate are anodized black for a stealth look. The gearbox size is optimized for good ground clearance.
The M1 drive is the first urethane gear drive to utilize a pair of hardened steel gears. The straight-cut gears are hobbed from 4140 alloy steel, then given a nitriding hardening treatment.
O-Ring Bearing Seal:
A unique o-ring bearing design has less drag than V grooves found on other gear drives. The o-ring compresses when installed to seal the drive from debris.
The wheel adapter and gear are interchangeable. Running a different style wheel is as easy as swapping the hub. Helical gears are coming in December 2020 and can be run in this gearbox with no modifications. Wheel adapters and faster 2.4 ratios will be available separately soon.
Longevity and Reliability
Gear drives exhibit “set and forget” installation. They require very low maintenance even after thousands of kilometers. The sealed design shields the gears from rocks that would destroy an open belt drive.
Performance and Efficiency
There is no belt skipping or ratcheting under hard breaking or acceleration. They can handle more torque than a 15mm belt system. Gears boast the highest drivetrain efficiency possible, having as much as 5-10% more range compared to a high performance idler belt drive.
