Faster - Stronger - Better

Includes all the parts you need to convert your bicycle to a motorised bike from only $235. Why settle for less?


Our 50cc engine provides the looks and reliability you expect from ZBox.  It is our budget product providing good fuel economy with awsome looks for $235 + shipping (with NT carburettor show).

This engine has all the features of our 80cc, however, the smaller capacity engine still packs a punch.

It has the same quality paint, Alan key bolts, quality bearings, single piece crank, and a raft of other features and it is backed by industry leading warranty.

Carburetor Options

The Taipan 50cc bicycle engine kit is supplied with an NT carburettor as standard.  Upgrading to the Taipan AC carburettor is recommended (an additional $15).  The AC Carb improves torque throughout the rev range, and provides easier starting.  The Taipan AC carb is a more sophisticated design and looks great with the conical, easy clean sports air filter.  

I have been using tuned ZBox engines for years. They guys provide great service and really know how to make these engine fly. I love to restore and motorise classic bicycles and used a lot of other brands before I found ZBox. Their engines have the finish, power and reliability that I couldn't find anywhere else.
