hi all
im in the end stages of a motorized bike build.
i used a 1960's murray beachcrusier frame (the engine front mount fits!) an 80 cc "raw" engine.
i made a rear engine mount (see pic.) and a bearing mounting plate for the jackshaft.,,,
jackshaft: engine side 30 tooth sproket.
pedal side 16 tooth freewheel
rear wheel drive cog 10 tooth
rear hub: sturmey archer 8 speed with drum brake with 25 tooth cog
front hub: sturmey archer with drum brake
it is the best motorized bike i have ever had (my third)
