Why Choosing The Right Bike Matters  

Selecting the right bike for your child isn't just about finding a fun ride. It's a decision that can impact their enjoyment and confidence when riding.  

In this section, we'll discuss why choosing the right bike matters and how to measure your child for a bike.  

Size and Fit  

One size does not fit all when it comes to children's bikes. Proper sizing and fit are critical to ensure your child's comfort and control while riding.    

If the bike is too small, it can impede your child's growth potential, leading to discomfort and reduced control.   

Conversely, if the bike is too large, it may pose handling difficulties and increase the risk of accidents. 

When all else fails, you can read our kids bike size blog to determine what size bike your child needs. 

Safety First  

Selecting the correct bike size is paramount for your child's safety. A bike that fits well ensures they can maintain control, reach the brakes easily, and touch the ground while seated.    

Prioritizing the right size not only enhances comfort but also significantly contributes to a safer biking experience for your child.  


Kids can be rough on their bikes, and durability matters. You want a bike that can withstand the trials and tribulations of childhood, from the inevitable spills to the rugged terrain.   

The Woom 6, Frog 69, WeThePeople CRS 18, and Frog MTB 72 are built for active young riders.  

Types of Bikes   

Understanding the different types of bikes available can help you make the best choice based on your child's interests.    

Whether they're into cruising around the neighbourhood or hitting the trails we'll explore how these bikes cater to various styles. For more info on our bikes, check out our bike guide.

Questions We Get Asked About Bikes For 9 to 12 Year Old Kids  

What size bike should I get for my 9 to 12-year-old?  

When choosing a bike for a child aged 9 to 12, consider their inside leg measurement. In most cases, a bike with 24 inch or 26 inch wheels will be the best fit. Ensure they can comfortably touch the ground when seated. It’s best to find a bike based on their inside leg measurement.   

Should I choose a bike with gears for my child?   

Whether or not you should opt for a bike with gears depends on your child's riding terrain and experience. Gears are beneficial for varied landscapes and skill development. Beginners can start with a single-speed bike, while older or more experienced riders may find multi-speed bikes more versatile. You can see our blog on how to know if your child is ready for a bike with gears.   

How often should I perform maintenance on my child's bike?  

It's important to regularly inspect your child's bike. Perform basic checks such as tyre pressure, brakes, and chain lubrication before each ride.
