Tyres Burst

Both tires on my bike burst. I think it may be cause by the concrete strip that separate the grass from the tarred surface. Replacement of the tires cost $12. It is inconvenient to send to the shop and then pick it back up. I am glad it did not cost too much to repair. Cycling is a fairly low cost exercise compared to yoga or gym. Thrift is a virtue. I will always look for economic ways to achieving my aims and minimise damage to our Mother Earth.
