If you buy our complete system less the engine component, we supply all the mounts and controls.

We even include drive arbors worth over $100 dollars. Free! Then choose direct drive or automatic. While we can't fit many of the Chinese engines, we do fit almost all of the DIN rated engine products. Designed to fit engines with otherwise 78mm clutch shoes.

Start by laying out all your parts.

Tools needed. One 1/4" allen wrench, one 1/2 inch wrench.

Start by installing the strut suspension to the engine mount.

Use 4 Shoulder bolts ($16) to attach the arms first, then the support body. Stainless/steel washers to outside, with the white nylon washer inbetween the aluminum parts. Then snug up the bolts as shown. The strut is pivoting for and aft, but not loose.

Now drill two holes into the support body as shown.

Insert turned eye bolt onto engine mount.

Slip yellow zinc spring through turned eyebolt and hook into forward hole drilled into support body. Install rear spring later.

Now attach your engine and tranny to the mount. Mounts are made differently for direct drive, vs. centrifugal operated systems to accommodate different bolt patterns for different engines.

Below are different mounts that attach to your new "shift on the fly" engine mount. This is a legal form of bike motorization.

Choose from different bike mounts, as this engine/tranny mount is universal in its ability to raise and lower while riding. SO below are additional parts you may need. We offer a complete package at a reduced price at
