Question Step-Through MotoPed*?

would a "girl bike" (no top tube) frame be strong enough to make a motorized step-through?

heh... upon closer inspection, the old piece of rust i bought today appears to be a girls bike with a top tube half-a**edly welded on no wonder i'd never seen a frame quite like that!

the bike has horizontal drop-outs and a coaster brake. i could put a 5-speed hub on there pretty cheap, i think, and be done with the derailler when it comes time for the Pablo and Ghost jackshaft kit...

thanks, fairracing! that engine sits pretty high, huh? the bike i bought today is a rusty old Murray which has the two down tubes like that one, but they're curved in such a way that the engine would sit lower.

i think this old bike might make for an interesting build if i got rid of that top tube that was so crappily stuck on it, but i'm still wondering about the strength of the girl bike frame geometry; seems like a triangle missing a leg. wonder if the chances of sudden catastrophic frame failure would be in any higher than on a men's frame if i bolt on a little Morini?

My first build was on a 24" schwinn girls bike. I called it the sissy schwin. I used a broom stick for a top bar to mount the gastank on. Was a nice little bike and i ran it a lot of miles before I decided to go for a bigger bike.

Check out the bottom picture on my blog it is the sissy schwinn with broom handle

thanks, deacon! a broom handle, huh? you should just go ahead and build a wooden bike

yeah, that looks more like the frame i've got, except this one does have 26" wheels. very rusty wheels, but 26" nonetheless. i wish my camera was working

i think i'll call her The Defiant, since i'll need a little attitude if i'm gonna be riding a girly bike
