Re: a couple mods I would like to try ....
Great, helpful answers all.
I did manage to complete my freewheeling sprocket adaption today with out thinking at all that I would not be able to bump start. I will have to try to add this pin lock idea tomorrow when I (was) to test drive. I will post all if I end up with anything noteworthy. (or is there any other way to start one of these things?, rope start adaptation?)
I will take the advice and buy a drum brake from Ginny. Not having ever done this change out, is the idea that things are standard and I will be able to use the same spokes that are on the wheel now? (new schwinn point beach 26x2.125) I will at least get in the first big workout for my truing stand and spoke wrench! Wish me luck.
