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...
