As parents, we all want the same thing for our kids: a bike that provides safety, comfort, reliability and ease of use without breaking the bank. We want your child’s first riding experience to be as memorable as yours, and that’s why every child’s bike that carries the Trek name is held to the same rigorous standards as all the products that we make. The bottom line is that getting your child on a well-designed machine is more economical for you in the long run, is easier to learn to ride and ultimately more enjoyable for your child from day one.

Bikes are not toys

This may go without saying, but a bicycle is not a toy. While the prices of mass merchandise shops may seem enticing, these bikes are often poorly designed and were not assembled by certified mechanics. A bike that may seem “pretty” or “cool” standing next to the toothpaste aisle will often not retain resale value or remain functional for a younger sibling, and is ultimately a bad investment. Trek bikes are engineered and crafted by people who care about bikes and their riders. In the end, a good rule of thumb is that you should never buy a bike where you buy your cereal.

What size bike does my child need?

Kids’ bikes range in wheel size from 12-26". For simplicity’s sake, it’s easy to think about your child’s age when determining which size is best for them. Though the guidelines below are general, they go a long way in zeroing in on where to begin your search.

Kids’ bikes are optimised around these wheel sizes in terms of fit and performance level. As wheel size increases, so do the number of options to accommodate the additional skills and riding preferences of older children. While Trek offers one incredible balance bike for the youngest tots, larger wheel sizes include multiple models optimised for road, mountain or city riding.

Beyond wheel size, the factors driving your decision should be colour/style, training wheel compatibility, brake type, gearing and finally category.

What’s a balance bike?

Balance bikes have become popular in recent years as savvy parents have recognised that balance, rather than pedalling, is the most essential component of riding a bike, and should therefore be the starting point of any instruction. They allow small children to push the bike with their feet, and then place them on stationary platforms to coast and practise balancing. It’s easy to think of them as a cross between a scooter and a bicycle. Trek’s Kickster is the best option for the youngest riders, and teaching them to balance early on will make their transition to a bike with pedals much easier.

What's with these different brakes?

Most bikes designed for the youngest children feature an easy-to-use braking system where simply pedalling backwards engages the brakes. You’ll hear this system referred to as 'pedal brakes' or 'coaster brakes'. Quite simply, it is easier for the youngest children to use their feet for both acceleration and braking, allowing them to focus on more essential skills like balance as they are first learning to ride.

As with stabilisers, pedal brakes are only best for children who need them to ride confidently. Hand brakes designed for the size of a child’s hand and reach are easy to use, and are far more effective in all riding situations. This means that hand brakes are ultimately the safest choice for children able to grasp their operation. Those who fit on a 20" bike are generally old enough to use them effectively, so we introduce hand brakes at this wheel size.

Should my kid's bike have gears?

Gears are great. Gears significantly increase a bike’s versatility, and reduce fatigue so that your child can participate in longer rides with the family. As with hand brakes, some amount of gearing will be beneficial to children who are able to operate them properly. Trek dials in gearing for a child’s age and assumed strength, meaning that the range is optimised for weight and performance at each of our kids’ sizes.

Trek introduces gearing at the 20" wheel size on models designed for children who have already developed solid bike handling skills. These include the Precaliber, Rosccoe and Wahoo families. There are 6- and 7-speed options at this size, while the 24" and 26" wheel sizes include a number of 21-speed options as well.

In the end, the ideal gearing for your child depends on the type of riding they will be doing. Longer rides on more variable terrain will require a wider range of gears. Youngsters interested in exploring mountain biking or getting serious on a road bike should have more gears than a kid who will primarily be cruising the neighbourhood with friends.

What else do I need?

Remember that it takes more than just a bike for your kid to have a safe and enjoyable riding experience.

A comfortable helmet that fits properly is an absolute necessity. Your child needs to wear one every single time they step on the bike. A light such as Bontrager’s Flare R, the first rear light designed for visibility during all hours of the day and night, is another safety accessory that is just as critical as your child’s helmet.

To keep things rolling smoothly, a pump and some spare tubes are good to have around. Your child may want accessories such as a bell or horn. Once they are going on longer rides, you may want to consider cycling-specific clothing, gloves and a dedicated set of shoes/pedals.

Remember that the most important component to your child enjoying riding their bike is you. A supportive and patient teacher is the key ingredient to creating an experience for a child to develop a lifelong passion for cycling.
