This bike will be built with parts on hand and other less expensive parts. This bike will be used mainly to pick up groceries and similar. no need to get into the triple digits on cost, so spinergy is kinda out. It I will see how wheelchair wheels fit my design and check on ebay for some good deals.

I don't plan on using a differential. It's going to be similar to how a go Kart rear end is set up. Simple yet works great.

I might use a 3 speed crank if I decide I need some gearing.
