Re: Yet another n00b...
I saw those in the store (walmart) today. They look interesting, but you've got your work cut out for you to motorize that. All the usual stuff. (check your hubs with real cone wrenches, reinforce the fenders with real steel brackets or ditch them, replace the coaster brake strap, add a front brake, find the mounting hardware for the engine if it's a china kit. Try googling it or searching here, see the reviews by people that motorized them. Probably it has been done already.
