The Components

Put it Together, Get Ready to Ride!

You've got a lot of leeway when installing the parts and components. We suggest spending some time looking over the parts offered from suppliers and the information in our own parts section.

Seat and Mounting

You can make your own two-passenger seat as shown in fig. 1, or buy one from the parts houses. The seat will mount in the rear to a support made from the rear fork (fig. 3) that was cut off the bike frame, or fabricated yourself. A 90 degree seat post, a stock bicycle item, is needed to move the front seat mount farther forward. If this is unavailable, improvise.


You can find chromed fenders from parts suppliers, and you may mount them in an adjustable way shown in fig. 4 and fig. 1.


If you've used the bicycle frame, any standard set up handlebars should fit. You can get high rise "ape hangers" or swept back bars. It's up to you and what you can find.

Throttle Control

Parts houses sell twist-grip throttles in both 7/8" and 1" sizing. This will fit most of the handlebars you may encounter. The throttle cable should be routed to the engine and installed according to the make and model of the engine. Zip ties are great to keep the throttle cable out of the way.

Wheels, Tires, Axles

The recommended wheels and tires for this rig are the standard pneumatic 4.10 x 3.50 x 5" wheels and tires. You can also of course use 6" wheels, or four inch, it's up to you.

For the front, you can use most any hub. The rear will need a double flanged hub to accept the sprocket. See the parts page for more info.

The axles should be 5/8" or 3/4" steel, and you'll buy bearings to match. Axles are readily available from the parts houses in a variety of lengths.
