Sizing and Safety
You need to be able to move the bike around underneath you without bruising your thighs, and to have the confidence to take a fall without any serious injury.

Crotch Clearance
For off-road riding, have at least 3-4 in (8 to 10 cm) clearance from the crotch to the top tube.

















Too Big
A high top tube is fine for town riding and smooth road touring, but you will still need at least 1 in (2.5 cm) of clearance. A top tube that fits too snugly might lead to a painful accident.












Too Small
A very low top tube means that it is easier to perform stunts and tricks on the bike. However, unless you are small, the reach wil be too short, and the ride very uncomfortable.














Think Small
Many first-time mountain-bike riders feel more comfortable on a frame that is actually larger than they need. Smaller frames are much more manoeuvrable, lighter, and safer. Select the smallest frame that gives you a good averall fit.
