When working on a new project its always a good idea to plan ahead, its easier to build around parts you have then to find parts that will fit what you have built.

This is a preliminary list of components for the mechanical aspect of the Medicycle and where to find them.

Chain tensioners 15mm for Pit Bike

Sunstar 32T Steel Rear Sprocket Kawasaki KLX110 03-09 (Jawzy’s PowerSports Inc., 1515 West 130th St STE A, Hinckley, CH 44233-9169 330-273-6161 USA)

Sprocket needs to be for 420 chain size basically.

You can get alloy sprockets but as sprocket smallish in relation to wheel (so lots of pull on it from gear motor via the chain) we preferred to get a steel one.

420 pitch chain:

Welding gear:

Nothing sophisticated here:

Basic hobby MIG welder with disposable CO2 cylinders will be fine.

Box and round section steel in lots of sizes. At each stage consider the weight of the machine, need to keep total weight under control but keep very strong where required. Our wheel/motor frame is probably over-strong right now and area around hinges also very strong to avoid twisting. Our steel came from hardware store – an expensive way to buy it but then we do not need large amounts. You can also get steel box section etc on ebay delivered to your house if you prefer.

Alloy would be better for a commercial machine but advantage of steel is it is easy to saw off and change something, also project has to be capable of being built to a basic working standard by a hobbyist.
