Ok, i have a project, ive been doing motored biking for a while and been doing it the fast cheap amd wrong way. That just a pain and its expensive and frustrating. So im going to do it right and i want some advice. Heres what i have 2005 mahattan cruisers aero delux 6 speed. (Currently a 5 speed, got it used and modded) Astabula crank will have to be replaced for: 4 stroke HS engine and gear reduction Sick bike parts 4 stroke shift kit Board track style wheels from custommotoredbikes.com with 11 ga spokes with a sturmy archer 3 speed igh with drum brake, front, sturmy archer drum Wald large dual basket rear rack 3 gal plastic marine gas tank on the rack later to be replaced with a cylindrical aluminum tank of similar capacity Will use a dual pull lever for the brakes, will use a locking clutch lever from a previous unsuccessful build in lieu of a twist throttle Other components will be determined as needed So, Who has the best HS 4 stroke motors and gear reductions and whats the deal with the G designation on the 4 stroke motors? 4g 5g 7g etc. Does this matter? The reason im going with such a costly wheel option is multifold: Im a heavy guy and i have had LOTS of issues with cheap trashed hubs, and broken spokes riding on the crappy roads where i live. So i opted for heavy duty wheels with the largest spokes i could find. I dont think an external gearing system would be very good with the jackshaft and i dont want to fit a new mech on the cruiser and a new shifter etc. ALL the other HD wheels i have found with IGHs have been coaster brake set ups, which i think that i should avoid at my weight and this is the only one i have found in a wheel which isnt a coaster. The drum brakes are because they are sealed and reliable from my reaseach, and they make tire changes a bit easier in my reckoning. Is my reasoning right here, or am i over reaching? Thanks to anyone who replies amd gives advice.
