This is a 26" MTB frame with a nice long seat post and handlebars off some kid's discarded BMX bike. This is a much cheaper solution to getting a comfortable upright position than buying a stem riser for a stock bicycle...plus you get all that extra bar space to mount your gadgets on. Since it's a bike you're probably not going to spend a whole lot of time pedaling, I wouldn't worry too much about the perfect fit, as long as you're comfortable and the engine fits the frame.
Personally I'd love to have a set of 190mm cranks for my unpowered bike, but at this point I don't have $400-$500 to waste on them.
