Kids Bike Size Guide
Which Kidvelo bike is right for your child ?
A Kidvelo Balance Bike is sized based on their wheel diameter, i.e. Rookie 12, Rookie 14 or Rookie 18
All our balance bikes require you to know your child’s inseam. This will allow you to select the correct size bike, while allowing some future growing room
Please bear in mind your child has to be able to sit on the bike seat, having both feet flat on the ground, with a slight bend in the knee
1. How to measure a child’s inseam
Tip! – Measure their inside leg/inseam with shoes on.
Measure your child’s INSEAM. Leg length is critical when gauging the correct size of bike. Please don’t just size a bike by the age of your child. Everyone is different!
The fit: Remember a balance bike is different to a pedal bike as children’s feet need to touch the ground. When sitting on the bike, kids this age should be able to put both feet flat on the ground. This helps children learn balance quickly and prevent tip-over accidents.
- Stand the rider straight against a wall
- Put a book between their legs
- Measure from the top of the book straight down to the floor
- That is your child’s inseam
2. Bike Weight needs to be in proportion to the rider
Experts recommend bikes shouldn’t be more than 30% of your child’s weight.
Heavy bikes over 4 kg will prove challenging to manoeuvre. Young children get frustrated easily. We often hear, “my child doesn’t like their bike,” and when we delve deeper, it is because they have a hefty steel bike with incorrect geometry or stabilisers.
Choose the lightest you can afford without eliminating all the features that make it comfortable to ride.
The Rookie 12″ is 2.89 kg and can be handled comfortably by the smallest riders. The Rookie 14” is just 4.7 kg without pedals or 6 kilograms in pedal mode. Kidvelo Bikes are made from top-quality 6061 aluminium alloy to keep the weight down.
3. Consider which size wheels you need
A 10″ wheel may allow for a lower starting seat height, but check the seat height range to get some years’ use out of it.
A quality 12″ wheeled bike may still achieve low seat positions, but the bigger wheel avoids speed wobbles.
Older children need bigger bikes, so consider a 14” or 18” bike.
If the child is a beginner, then a 2-in-1 bike is perfect as you get the benefit of learning in balance mode before converting to a bike with pedals.
4. Tyre Types
Tyres play a crucial role in the performance and comfort level of a bike
The type of tyres will determine the smoothness of the ride and the traction achieved on various surfaces. There are four types of tyres used. These include foam, air, plastic, and rubber tyres.
Pneumatic tyres give the most cushioning and traction and are considered the best all-around solution. Foam tyres are cheaper, lighter and generally puncture-proof. However, they lack traction, something we have witnessed firsthand in off-road riding. Rubber tyres are pretty solid, puncture-proof, and have better traction than foam tyres which aren’t comfortable over rough terrain. Plastic or EVA polymer is the lightest but lowest quality and typically only lasts a year. However, 12-inch pneumatics will offer longevity, far longer than a plastic 10″ wheel.
All Kidvelo Bikes come with Alloy rims and pneumatic tyres, perfect for any terrain riding. Our performance wheels are strong and very light.
5. Brakes or Not ?
Balance bikes work by using feet, safely placed on the ground, to move the bike along and to stop. There is a tendency when buying anything, to think that more features offer better value. When choosing for young children, the easier the bike is to use, the more successful they will be.
Brakes aren’t a good idea for young child as they will stop with their feet, which is intuitive and the safest method. Our experience has shown us that having lever brakes confuse young kids. They don’t know what to pull or they don’t have the finger strength to pull them so the child doesn’t stop quickly enough.
We also noticed that the reach on some brake levers isn’t adjustable enough. Worryingly, we have witnessed the kids taking their hands off the handlebars to pull the lever. For this reason, the Kidvelo 12″ balance bikes do not have brakes. Kidvelo Bikes for 3-year-olds and older do have brakes.
6. Do you need a footrest or deck ?
Our bikes come with a footrest, so feet can be placed correctly when the child is balancing. When just starting out, the child won’t be lifting their feet far from the ground. As the child gets more experienced, they start lifting their feet for long periods of time. This is when the footrest is useful. If you ride your bike, then you wouldn’t ride off a curbside or over a bump with your feet dangling in the air. You would have your feet on the pedals and take the knocks in your legs. If you have feet in the air, it’s your bottom that takes the judders and it’s painful.
A footrest allows children to place their feet when coasting and balancing. Our footrests are designed to be in the correct position to mimic where the pedals will be, and in the convertible bikes, it gets swapped out for the pedal kit. Children are learning balance in the correct position to ride a bike from the start.
7. Geometry is Important
Suitable bike geometry will work with the child to help them learn to balance and manoeuvre, whilst a bike with poor geometry will work against them.
Learning to balance is done by walking, running, and gliding. It’s natural for kids to lean forward when running. But to be able to do so, they need plenty of room.
That said, you need to consider geometry that creates more space between the handlebars and seat post—making it easier to extend the legs for a more comfortable and natural run style while striding. It also means that the handlebar reach is still correct as the child grows bigger.
Watch the step-over height. A low step-over frame is much easier for children to get on and off. On the other hand, some bikes have a very high frame exactly where the child needs to get on and off, making it more difficult. Cyclesprog explains what they love about our design.
The same balance bikes work for girls and boys. Kidvelo Bikes have a low step-over frame making them easy to mount.
All bikes in the Kidvelo range have quick-release clamps to adjust the seat height, and a scale marked on the post so you can easily fine-tune as children grow. Handlebars that you can set for near or far reach and adjust the height. Our grips are scaled for little hands to give the rider complete control.
Don’t make your purchase based on age alone. There can be a huge difference in leg sizes/inseam between children in the same age group.
Seat height-adjustability is crucial so that the bike will last a few years. When buying balance bikes, you need to check the seat height allows for a slight bend in the knee when feet are flat on the floor, allowing the bike to be walked or run along.
9. Choose the bike to match your child’s size & ability level
Don’t stress this bit. Our experience has taught us what approximate age children pick up the varying skills required to ride. Kidvelo bikes are sized correctly and consider what skills each age group can handle confidently.
Really young children should start on the Rookie 12 bike without pedals, brakes or stabilisers.
The Rookie 14 (a convertible pedal bike), has front and rear brake levers and transforms into a pedal bike by installing the included pedal kit. Ideal for those moving off their 12″ or just starting to learn at 3-years-old plus.
Older children will need the Rookie 18 version as it is bigger again.
10. Transitioning onto pedals
The rider needs to be comfortable with the weight and handling of their balance bike before transitioning to pedals. At Kidvelo, we make this process simple by giving you a larger, slightly heavier bike that you can use without pedals fitted to start. Get used to the increased weight and size and start learning how to use the brakes.
Once your child has mastered balance, our unique conversion bike converts to a pedal bike with the easy-fit pedal kit.
Why buy two bikes when you can have the next generation of kid’s bikes with the Rookie Convertible Balance to pedal bikes. (Arriving Autumn 2022). This design gives your child the best chance to learn balance without the complications of pedals.
If they aren’t ready and you need to go back a stage, you can easily remove the pedal kit again.
