It is very important to pick up correctly the bicycle frame size as not only the comfort and convenience when driving will depend on it, but also safety. The additional complexity is represented by distinction of designations at producers – the size of the frame can be designated as in inches (""), centimeters (cm), and conventional units (XS, S, M, L, XL).
It is required to you

Instruction
1. Select the mountain or city bicycle taking into account the growth according to the table. If your growth appeared on border of two recommended sizes, pay attention whether the design provides the depreciation subsaddle pin. As it doesn't allow to lower the saddle up to the end, at its existence choose the bicycle of the smaller size.
2. For trips to the long distance buy the road bicycle, it differs in the high top pipe. At selection of the frame consider, besides growth, the size of the top and subsaddle pipe. Get up near bicycle – the distance between the groin and the top pipe has to be not less than 5-8 cm (especially it is important for men).
3. When choosing the children's bicycle consider not only growth, but also age (though if your child grows quicker than average indicators, choose the bicycle of the bigger size). It is very convenient to use bicycles with the possibility of adjustment of height of the saddle and the wheel – in that case, the technique will serve not one year. Pay attention to the frame form - the below the top pipe will be located, the driving as the child will be able to jump off from the saddle in case of loss of management will be safer.
4. For active and extreme driving choose the frame of the smaller size, than for quiet driving on the flat road as such bicycle will be more brisk and operated.
5. If you the thin physical build, take the bicycle with big size, for full it is better to select the technique one size smaller – it will be easier to drive, sit down and get down. Besides, length of hands and legs matters: if you have short hands or legs, buy the bicycle of the smaller size better, or choose the technique with the minimum carrying out of the wheel and the opportunity to lower the saddle as low as possible.
6. Upon purchase ask for permission to get on the bicycle and to pass a little. The size of the frame can nominally suit you, but you will feel discomfort when driving – in that case refuse purchase, you shouldn't count that over time you will manage to get used to the uncomfortable position.
