Want some advice on buying a cycle. I am 5.3 tall and 86 kgs . Buying a cycle basically to be fit and to cycle around . Have done 20 -30 kms 5 times last month . Can cycle upto 40 with intervals in a day . and i am also new to tokyo , so not sure about the routes . Appreciate if someone throws some light on what kind of cycle to get and from where . and i am not looking for a expensive cycle . Thanks much .
