Decathlon BTWIN - First Section: Riding Position and Safety; Setting Riding Position and Safety

FIRST SECTION
I Setting the riding position and safety
1. Ensure that the bicycle is the right size
A bicycle that is too big or too small for riding is difficult to control and may be
uncomfortable.
Size of the frame (one inch = 25,4mm):
To check if the size of the bicycle is correct, just get on it and put your hands on
the handlebars. If your crotch touches the frame, the bicycle is too big for you.
There should be about one and two inches between your crotch and the frame.
