FAQs

Is this compatible with axles larger than 12mm?

No, this unit is engineered specifically for 12mm axles and will not fit larger or smaller dimensions.

Does this include a speedometer cable?

No, the package includes the odometer transmission unit only. You should reuse your existing compatible speedometer cable.

What is the primary function of the flat drive plate?

The flat drive plate is designed to provide enhanced stability during rotation, which helps reduce vibration and wear.

How do I maintain the transmission?

Keep the unit clean from road debris and ensure the swivel nut connection remains tight during routine maintenance checks.

Why is the square drive 29mm?

The 29mm height is optimized to ensure deep, precise engagement with the speedometer cable drive for consistent data transmission.

Troubleshooting

Speedometer needle fluctuates

Check that the speedometer cable is fully seated and that the square drive is properly engaged in the transmission.

Transmission will not slide onto the axle

Verify your axle diameter is exactly 12mm and remove any rust or debris from the axle surface before reattempting.

No speed reading

Inspect the internal square drive for damage and ensure the speedometer cable has not snapped.

Setup, Compatibility & Care

To install this component, you must first remove the front wheel of your scooter to access the axle. Ensure the 12mm axle is clean and free of rust before sliding the transmission into place. The swivel nut should be tightened by hand until snug to avoid cross-threading. For ongoing care, periodically check that the speedometer cable connection remains tight and free from moisture. Compatibility is limited strictly to 12mm axles; please verify your specific scooter manufacturer's axle diameter before purchase. Do not force the square drive if it does not seat correctly, as this may indicate an incompatible cable interface or improper alignment.
