If you enjoy cycling for pleasure, doing it in London can be a shock. There are not enough lanes especially for bikes, and making your way through the traffic can be very risky. But if you have great passion, cycling in London can be exciting, and it is an inexpensive  way of keeping fit if you live there. Some cyclists don’t mind spending a lot of money on expensive bikes. However, if you just want a basic bike that is only for occasional use, there are many cheap choices. Several markets have cheap bikes on sale which may not be impressive to look at but should be satisfactory. You should buy a cycling helmet if you want to cycle in London. Wearing a cycling helmet is not compulsory in Britain, but it is a good idea to wear one for protection.
