I need an engineering expert for the best possible design of a gear box for my front wheel drive bike project. Cad cam expertise is a must as well. I need to lock down the two 90 degree bevel gears at the hub of a bicycle wheel with a simple working design around my drive shaft and gear exiting the right side front 1.25" front fork and meshing with gear attached at the hub axle. A clamp around the hub axle like the motorcycles use that also clamps the extra bearing located beneath the bottom drive shaft gear is how I envision the solution. No square boxes please. Something round that looks good and also act as a cover of both spinning gears.
