    2 Stroke Kits


    The HT engine is a 2 Stroke engine with an NT carby. This is the most popular setup for motorizing a bicycle and generally the cheapest option too. 2 Stroke kits require oil to be added to the gas tank.

You do not need to mix oil into the fuel for instance and they are a lot quieter. This is just an introduction post so we wont go in to details here about which kit is the best. You can find plenty more information on the forum.
