Bicycle Engine Kits

2 cycle Engine Kits Get Great Gas Mileage

We have top quality bicycle engine kits. Here you'll find our 2 cycle engine kit, and a list of all the pieces of our engine kit.

The Bicycle Engine Kit

These kits are the same as the famous ZBOX kits, which have been sold for many years in Australia. We stand behind these kits completely. Please call us direct at 512-762-7196 with any questions.

Kit Contents

All parts seen below are part of our top-quality kits. There is everything you need to have to convert your bicycle to a motored bike!

Spare Parts

All engine pieces are available as spare parts. We carry all spare parts seen here, both individually and in bulk. Please contact us with questions.

Below: Inclined Head Kit

This is a new design on the market for late 2008 -- the Inclined Head kit. This kit allows a tight fit on your bicycle frame because the spark plug lays at an incline rather than straight up and down. This brand new kit design will fit more bicycles than the other kits available.

Below: A 66cc installed kit

Note that it uses an old-style head, not the inclined head as pictured above. The inclined head is only available on the 48cc engines.
