Faster - Stronger - Better

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

Petrol Engine Kits

Bicycle Engine 80cc

80cc Sports Engine Kit

Power packed motor kits for off-road use

The 80cc engine with sport carburettor is our most popular engine kit for a number of reasons:

It is the fastest bicycle engine available.

It provides the renowned ZBox reliability

It is the highest quality engine kit – Quality paint, Alan key bolts, quality bearings, single piece crank, and a raft of other modifications that make our engines stand out from the crowd

It is backed by industry leading warranty.

The Taipan Sports Pack includes the Taipan AC carburettor which improves torque through the rev range, provides easier starting, and has a conical, easy clean sports air filter.  We can replace this carburettor for an NT carb to reduce the price by $15.

50cc Engine Kits

Entry level off-road engine kit

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).

This engine has all the features of our 80cc, however, the smaller capacity engine is designed for fuel economy rather than speed.

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.

The Taipan 50cc bicycle engine kit is supplied with an NT carburettor.  Upgrading to the Taipan AC carburettor is recommended.  The AC Carb improves torque through the rev range, provides easier starting, and has a conical, easy clean sports air filter.  This recommended upgrade will add $15.

200 Watt Engine Kit

Road Legal (refer below)*

Our 200 Watt engine is designed in Australia to comply with road rules for maximum power output.

These engines are constructed in Australia and rigorously tested to ensure that it complies with the 200 Watt power limit allowed by legislation. *

The result is an with a similar top speed to 250 watt electric engines (around 25 KPH).  There are, however, numerous advantages of a petrol engines when compared to electric:

Travel distance is not limited by a battery. A litre of fuel will take you around 100 Klm, then you simply refuel and go.  You do not have to wait 8 hours for the battery to charge.

These engine are lower cost as they do not require expensive batteries.

Engines are backed by industry leading warranty.

Every engine is tested and issued with the engineers certificate of compliance, confirming that it produces less than 200 Watts of  power.

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.
