Details

Choose between rubber traction wheels and mecanum wheels in 65–97mm sizes, all designed to mount with hex couplings.

Six wheel options cover balance, racing, off-road, and omni-directional drivetrains from micro cars to larger robot platforms.


Match the 3mm hex coupling to 3mm output-shaft motors for a secure wheel mount using the included screws.

Use the 6mm hex coupling for 6mm output-shaft motors when higher torque setups call for a larger shaft size.




Detailed size drawings help confirm wheel diameter, width, and hub fit before choosing a rubber tread style.

Compare an off-road rubber tread with a compact 65mm mecanum wheel when planning clearance and handling.


Coupling drawings include the M4 threaded hole and key dimensions to simplify motor and hub matching.

Pick a rubber wheel based on the driving style—everyday grip, faster racing response, or off-road climbing traction.

A sponge liner sits inside each rubber tire to support the tread and improve contact during turns and starts.

A 4-wheel mecanum setup enables lateral movement, diagonal travel, and tight turning for omni-directional robots.

Omni-directional motion comes from angled rollers that translate wheel rotation into forward, lateral, or diagonal movement.

Installation examples illustrate how the 3mm and 6mm couplings connect wheels to common geared motors.

Real builds demonstrate how different wheel types suit everything from grippy rubber drivetrains to mecanum maneuvering.

The set includes angled-roller mecanum wheels and treaded rubber wheels with colorful hubs for different drive setups.
