Re: Broken rear pulley
Caused by jamming more power through it than it was designed to handle.

Definitely too much damage for Hello Kitty bandage. Better use two.
On the plus side, great excuse for a ZX conversion?

when it broke I was taking off into traffic. It made a rattling noise.
I pulled over to see what was wrong and noticed the rear pulley wobbling.
I continued to ride home at a slower pace (40mph)
two miles later the belt snapped
I pushed the scooter the remaining 1/4 mile or so.
