hi I'm new to building motorized bicycles and this is my second build and my power house will be a 6.5 honda clone and my question is if my gear ratio is too high, as of now i received my clutch witch is 10 tooth and my rear sprocket is on its way and its going to be 60 tooth at a ratio of 6:1 and theoreticly i can hit 47mph (75kmh) with 26'' tires at 3600 rpm to me i think its kind of high because the clutch locks at 28mph (45kmh) any help would be appriciated and also I'm on a really tight budget.
