Back on topic - yeah I have wondered if you can bolt them into your rear dropouts like a diy longtail... I also have a dead suzuki TS50 and am trying to figure work arounds on that - nice wheels, fit into a 24" frame, but then maybe the swingarm off the TS could also bolt in, then run jackshaft... floating off topic again...
The bigger question is whynot just strip the GY6 naked, and then bolt on the top part of a cruiser frame you like, to make it look like a motorised bicycle....
Just quietly though I've read the quad/atv gy6's put out to chain transmission.... now thats handy for MBrs eh?
Did you buy a 49cc? I have 2 of them. They would bog down when accelerating too and top out at 25 mph . Turns out they had electronic rpm limiters on them. Causes them to cut out repeatedly when trying to accellerate with full throttle.
I took the limiters off, and now they run like different machines. They both accellerate smoothly top out at 38mph now.
The speed limiters are the little matchbox sized device in the battery compartment with 2 wires plugged to it. Simply unplug it.
