Last year, I rode about 1000 miles between the two Chinabike kits, about 300 with the current front mount bike (see my avatar).

I rode the big Suzuki somewhere over 2000 miles and my little Yamaha Vino 50cc scooter got about 1000 miles of use.

Every time someone stopped by the shop, guess what they wanted to "take out for a spin"?

So proportionately the Chinabikes got a lot of riding...
