Bullitt is a go-go.


Electric engine on a Bullitt cargo bike. This is a heavy duty piece of kit costing around £2000. This gave me the idea to do the same with my Robin 35cc petrol 4-stroke engine but run via an American, Stanton gearbox. You can find them on the net and they reduce the engine speed via cogs to 18:1. I bought and adapted a two ring chainring, 35 teeth and 56 teeth with the chain from the engine going to to the larger chanring. In this way the engine speed should be the same as my pedal speed and all the power is being transmitted to the rear wheel via the hub gear. I hope this will work!Bull
