Choosing Your Bicycle

Choosing a Bicycle for a Child
Choose a bike to suit your child's height and build now, not one they will grow into. If it is too small they will quickly become tired but if it is too big they will not be able to dismount correctly and risk falling or crashing.

Younger children don't need gears but many manufacturers fit them anyway. Look for a bike that is simple to operate making it easy to jump and ride. Introduce children to geared bikes from around the age of six or seven.

The bike should be small enough so the child's feet touch the ground when sitting on the saddle. This gives kids confidence and is opposite to the advice given for adult cycles. Unlike adult bikes, children's bikes normally come in wheel sizes, not frame sizes.

Look out for cheap brakes and brake levers. Plastic levers for example are fitted to reduce costs and often fail.

Use the table below to find the right size for your child:

Age Inside Leg Height Frame Size Wheel Size
3-5 yrs 13.5" - 16" Under 90cms 8.5" 12"
4-7 yrs 15" - 17.5" 90 - 115cms 9" 14"
5-7 yrs 17" - 20.5" 105 - 120cms 10" 16"
7-11 yrs 20" - 23" 115 - 140cms 11" 20"
7-11 yrs 21" - 24.5" 115 - 140cms 12" 20"
11-14 yrs 23" - 26.5" Over 135cms 13" 24"
11-14 yrs 23.5" - 27" Over 135cms 14" 24"

Choosing a Bicycle for an Adult
The bicycle you choose will depend on it's purpose and your budget. From mountain crossing to just plain fun there are a huge variety of bikes available including multi-purpose for simply going to work but also going out at the weekend. Ask in your local bike shop for advice and don't forget to check out some of the links on our cycling page.

Sizing a bicycle for an adult is the opposite to choosing one for a child - both your feet should not reach the ground when sat in the saddle. You must not feel stretched or hunched over to reach the handlebars either.

Legs must be slightly bent when pedalling to get the most power but if you can touch the ground with both feet when you’re sat in the saddle, the bike is too small for you or the saddle needs to be raised higher up.
Adult bikes are normally sized by frame. Don't be afraid to try out a bicycle in your local shop, they should happily let you sit on it and try it out.
