You can ride a bike of any size – heck, look at circus clowns – but that doesn’t mean it will be easy, comfortable or fun. For your everyday needs, a bike that is the right size for your body is going to provide you with the most enjoyable experience. Here are a few tips on choosing the right size bike:
For Kids: Never choose a larger bike for your child thinking that he’ll “grow into it.” A bike that’s too large is difficult to handle and may make it difficult for your child to ride. This can destroy his confidence and even lead to accidents. There should be 1 to 2 inches between the top tube of the bike and your child’s crotch. Make sure your child is wearing non-heeled shoes and is standing flat-footed when you measure; for girls measure between the crotch and an imaginary top tube. If you’re buying a bike for a child who’s not present, as a gift, for example, measure the child’s inseam and subtract 1 to 2 inches – this is the correct standover height, or the height you want the bike to be from the ground to the top tube.
For Adults: Sizing bikes for adults isn’t very different from sizing them for kids. Most adult bikes have 26-inch wheels, a top tube for men and a sloped top tube for women. When measuring for a man, straddle the bike with your feet flat on the floor and check to make sure you have 1 to 3 inches of space between the top tube and your crotch. For women, straddle the bike in the same way and measure 1 to 3 inches between an imaginary top tube and your crotch. Both men and women should reach for the handlebars, making sure they are a comfortable height and distance. The handlebars shouldn’t feel too far away or too close.
Ultimately, it comes down to your comfort – how does the bike feel when you take it for a test ride? Is it comfortable? Easy to control? If so, then you’ve probably got the right fit.
