Sizing Tips

When you straddle the bicycle frame with your feet flat on the ground, as illustrated here, you should be able to clear the top tube (crossbar).

Although every manufacturer has their own sizing quirks, a bike's frame size is based on the length of the seat tube (the tube that the seatpost goes into). Please see the tables below for sizing guides

If you prefer more athletic riding, particularly mountain biking over rough terrain, you are safest with maximum clearance, so plump for the smallest possible frame - as long as you can still stretch your legs and the bike isn't so short that it cramps your riding style.

If you like to sit upright, go for the biggest frame that still allows top tube clearance.
