Hi guys i was just wondering if bigger spokes on a bicycle rim makes it stronger? and by how much? And were can i get heavy duty hubs that can handle hi speeds. i want to buy a honda 125cc motor and build a nice bike to put it on.
Wow a honda 125cc? That is a whole new ball game compared to these little 49-66cc engines. I've ridden plenty of honda's and Kawasakis, yamaha's etc and the first thing that comes to mind is a bicycle exploding under that kind of power! My old yz80 was putting out nearly 22 hp (100cc kit, fmf and stuff) and there is no way a bicycle could handle that kind of power, that i know of. Maybe you have some ingenious plan but man that scares me! My little yz would stand straight up from a dead stop! That kind of torque would twist a bike frame like a pretzel if you could even get the power to the ground! I sure would like to see it if it can be done! That would be something!
Consider Husky or Worksman wheels...or custom wheels made by the Wheelmaster. I have Husky wheels with 11ga spokes. Most bicycles have 14ga standard. Most "heavy duty" wheels have 12ga...which are pretty good. That I have seen (there may be others out there) only Husky and Worksman sell wheels with 11ga spokes (Husky sometimes call them "HD-120" because they are .120 inches thick). The Wheelmaster can custom build wheels with 9ga and 10ga spokes. The Husky heavy duty steel rims are strong, but the standard for strength is probably the Worksman.
