I guess this could be considered a Motorized Bicycle..I have a question on gearing drive train setup..
These Safti-Cycles were made in Wisconsin..In the first pic you will see what I purchased a couple weeks back for a somewhat rat build you could call it I guess. Secone pic is where I am at with it....It is more less a glorified Bicycle with a motor..They came with Clinton engines.. I am putting a Honda GC190 in it..All the plastic and such will be stripped from it.. I will be putting a kickstarter on it.
Anyway I have some questions regarding drivetrain.. The Honda Engine is a 6.2 HP.. The wheels are actual Mpotorcycle wheels and are 23 inches tall with tires mounted.... It will have functioning front and rear drum brakes..I am hoping to get maybe around 40MPH plus out of it..
My first thought to try is just a centrifugal 10T clutch and around a 60 tooth rear sprocket.. But I do not know the feasibility of that simple setup..May work, may not.. Next option I think would be a Belt clutch off the engine to a jackshaft then a chain to the rear sprocket..Want to stay as simple as possible, but will do what I need to to get there..This thing will probably approach 140 pounds when fully assembled..
Knowing the tire size, engine HP and weight..What kind of setup might you suggest I try? I am not good at figuring ratios and such on something like this at all.. Any help would sure be greatly appreciated..
Any a couple pics..My engine should be here tomorrow.
