This size is generally for front tube diameters that measure 1_1/2". Always measure! Some require reducer bushings for non-standard diameters.

The front engine mount (T-bracket) mounting component has 2 slots to adapt to any of the Chinese engine front stud spacing configurations.
Some engines have wider stud spacing for the front mount, that's why there is 2 slots on the front mount (T bracket) mounting component.

The rear engine mount (T-bracket) mounting component has 1 hole and 1 slot.
This is because the drive sprocket is very close to one of the mounting studs on the rear mount application.
So the rear (T-bracket) mounting component that has the hole will mount on the stud nearest to the drive sprocket.

SELECT FRONT OR REAR IN OPTIONS WHEN ORDERING! To be sure you get the proper (T-bracket) mounting component!
The frame clamps are interchangeable

Compatible with all Chinese motors that have 1-1/2 - 2" stud spacing's

Benefits:

  • Easy, fast, secure, engine installation.

  • Eliminates, annoying, broken fasteners.

  • Designed and CNC machined to match your engine and bicycle frame geometry.
