Repeted hard braking with a coaster brake will burn the grease and gum it up. You definately need to coast speed down and use less brake and repack the grease often.

| | How do you stop?
If you look up the history of the Whizzer their biggest fault back in the late 40's was the fact that they could go but stopping power being dependent on the coaster brake was not very reliable. It didn't stop them selling close to 200,000 units back then though. |

Hi street rider why dont you try having the axle wellded by a profesional some times the welding equipment determines the strength of the joint, and you can mount two sprokets on the axle so that you get the kick that you wanted. |

There are differentials some 3 wheelers come with and maybe you need one as the solution to breaking axles?

I was told by a local bike dealer that Schwinn still makes three wheel bikes.
Might check around your area for parts. As for the fuel milage on a 70cc it really depends how you ride, hills,wind, your weight, ect.
