Christmas may be the traditional time to pick up a cheap children's bike, but with summer having arrived, many of the best mountain bike brands and online retailers have loads of children's bikes for sale. 

I've been hunting around the internet and found some big discount deals on some of the best MTBs for kids. I've had my fair share of experience in selecting children's bikes and I have chosen models that I think tick the boxes in spec vs price. As parents, we all know the importance of getting the right bike in the correct size, and most importantly, in the desired color.

Gifting the magical journey of cycling to your child at any time is something seriously special, it can make many memories and start a journey in cycling that will last a lifetime. Getting your little shredders the best possible bike for the lowest price makes it even better, and who knows your boy or girl could turn out to be the next Mathieu van der Poel or Pauline Ferrand-Prévot. So read on for my best bike deal selections and I've also added some additional buying tips with some pointers that may help when it comes to choosing.

1. Rocky Mountain Reaper 26

The Rocky Mountain Reaper 26 children's bike shares many features found in the adult full-suspension mountain bikes made by Rocky Mountain. The FORM alloy frame is durable and lightweight and features 130mm of Smoothlink suspension that should make the Reaper an efficient climbing and rapid descender. RockShox Recon Gold forks are paired with the RockShox Monarch R rear shock and add to the impressive build spec on the Reaper. There are also 26-inch WTB ST i21 wheels and premium Maxxis tires and with the 25% discount currently at Backcountry, it's got to be one of the best cheap children's bike deals around.

The Specialized Jett was my daughter's first-ever pedal bike, and has lasted her for a good few years, and coped well with the growth spurts. Specialized has specifically designed the Jett to be a perfect child-specific bike and is built to grow with the development of young riders, with tweakable features like a longer seatpost and adjustable handlebars. The Jett 16 has an A1 premium butted alloy frame and fork and features internal cable routing, a single-speed drivetrain, V-brakes with tool-less adjustable-reach levers, and tires that work well on the pavement and the dirt.

How to choose kid's mountain bikes

Bikes for kids have changed a fair bit since my day when the Raleigh Burner BMX was the super-cool must-have bike of choice. Today’s options generally mirror adult models in design, equipment, and occasionally even price. If you expect to take long or skill-intensive MTB adventures with your child, ensure their bike is just as capable as your own.

There are plenty of options when it comes to selecting a child's bike, and it can be a bit of a minefield at times, but I've listed a few points that I've found handy and are worth considering when picking your child's next mountain bike.

1. Size

Buying the correct size bike for a child is more important than buying your own. An ill-fitting mountain bike can be dangerous and off-putting to a youngster. However, it's not as simple as buying an adult bike, kids are constantly growing and a bike that fitted perfectly just a few months ago could easily be badly-sized after a growth spurt.

Many of the best mountain bike brands size bikes in age ranges and having purchased a few child's bikes over the years, they are a fairly accurate guide to choosing the right size of bike. If your child is on the edge of an age range then it can be slightly more difficult, and having height and inseam length can be a better guide. Most bike brands have either online interactive size guides, or height and inseam charts, accompanied by tips for measuring your child. They can be a big help, especially when ordering online.

If you're fortunate enough to be able to actually visit a bricks and mortar bike store then getting a bike perfectly fitting is a lot easier. Trying before you buy and seeking advice from in-store staff will help if you are unsure. Generally, making sure both feet touch the ground when in the saddle will give a good pedaling position but also allows the child to stop and put their feet down when they want to. The reach is also important and be sure that your child can not only comfortably reach the handlebars with both hands, but also the brake levers and shifters.

2. Weight

As adults, we are always looking at and comparing the best lightweight mountain bikes. Obviously, children are much lighter than adults, so their bike’s comparative weight becomes super important and has a big effect on how easy the bike is to ride. We wouldn't choose to ride a heavy bike ourselves, so saddling your child with a cumbersome heavyweight bike isn't a great idea, and speaking from experience, it can create tension out on the trails.

Most of the bikes featured above are lightweight alloy-framed machines and are fairly lightweight in relation to the size and age of the child they're aimed at. Ideally, find the lightest bike that you can afford within your budget. Most weights are listed, but not always, so if you're in-store that of course is far easier to check.

3. Cost

The bikes I've chosen above are all superb options and come with great specs and builds. Handily they are all discounted so your child is getting more mountain biking bang for your buck. Again it comes down to your own budget and there is also the growth consideration and other accessories to buy like a mountain bike helmet, protection and again speaking through experience, looking cool on the trails is very important.

4. Style

The look of the bike you select will be of importance to your child or children. A lot of the time other considerations like spec, performance etc will play second fiddle to the appearance. If it doesn't look good, then there will be complaints. So be sure to let them see what's on offer before pulling the trigger or the bike could be sitting in the garage unused. A hand-me-down bike can be frowned upon too, speaking from experience once again.
