After a year of heavy duty on my little A-bike, the middle part of the tread of the rear tyre have been worn away.


There's a crack appearing on the rear lower tube, too.


When I tried to go up a steep incline by my A-bike last week, the chain fell off from the gear suddenly. After opening the crank case, a crack has been found on the small spocket of the layshaft.

Therefore, I had to replace the following parts:

Here are the prices of the parts from MHM, the local distributor of A-bike in Hong Kong.
Rear Lower Tube: HK$500
Layshaft: HK$125
得把口, an A-bike expert in the local A-bike community, has helped me to replace those parts. We just did it openly in a park last night.



My A-bike is recovered now.
