Kids mountain biking is an exciting sport that is becoming increasingly popular in the UK. If your son or daughter is chatting constantly about bunny hops, grunts, kick-outs and nose wheelies, it’s probably time you start thinking about investing in proper mountain bike gear for them. With the right gear they will be able to get much more out of the sport and will be much safer in doing so.

If you’re worried about their safety out on the trails you could sign them up for an introductory kids mountain bike course to teach them everything they need to know to get them started in their pursuit to be a top mountain biker.

Or if you are in doubt whether your child will fall in love with mountain biking or if it will just be a passing phase, hire a mountain bike for the day and take them to one of the UK’s mountain bike parks to let them try it out and see how they take to it.

When choosing a mountain bike for your son or daughter, you’ll need to pick one with a slightly smaller frame than you would if you were buying a road or hybrid bike.

How To: Fitting a Kids Bike

Kids bikes tend to be categorised by wheel size rather than frame size ( 6-9 yrs = 18", 8-12 yrs = 20" and youth = 24")

However, on a mountain bike your child will need maximum clearance and so may require a smaller frame size than normal. If possible take your child to a bike shop to try out a few mountain bikes for size. Straddling the bike with their feet flat on the ground they should be able to clear the crossbar. For a road bike you would want there to be about an inch of clearance but for a mountain bike two or three inches would be better.

As a general guide, a child between 152-158cm in height will require a mountain bike with a 13-14inch frame. If you’re unsure which size bike your child will require, it’s always best to take them to a shop for a proper fitting.

Kids mountain bikes can be bought from most shops that sell adult mountain bikes including Halfords, Pearson Cycles and Evans Cycles. They can also be bought online if you’re certain of what size your son or daughter needs. Great online retailers include Wiggle, Trek and Cycle Store.

Everything You Need to Know About Buying A Second Hand Kids Bike

If you’d prefer to purchase a second hand kids mountain bike there are lots of great bargains to be found on eBay. Just remember that whenever possible it’s a great idea to arrange to view and test ride a second hand bike before committing to purchase.


Like any cycling discipline, mountain biking can be dangerous and so it is vital that you kit your kids out with the right gear. The most important item on the gear list has to be a top of the range helmet. This is one item that you don’t want to skimp on as it really could save your child’s life.

How To: Fit A Kids Helmet

Choose between a regular helmet or a full face one depending which you and your child feel would be safer for them. If they are planning on doing lots of jumps and tricks and advanced mountain bike trails a full face one would be the best choice. But if they just want a mountain bike to do some gentle off-road trails a regular shaped helmet is likely to be sufficient.


After the actual bike and the helmet the next thing to consider is whether your child will need proper mountain bike clothing and gear. If they are wishing to head out on trails and play around at mountain bike parks they’re likely to need at least the following basic kit:

  • eye protection
  • gloves
  • a wicking jersey
  • shoes
  • padded shorts or tights
  • cycling socks
  • a buff, bandana or skull cap
  • arm and leg warmers

All of this kit is easy to come by. Freestyle Xtreme has a great range of mountain bike specific gear and clothing and all of the major cycling websites and shops have a range of kids bike jerseys and clothing.
