Finding the right children's bike: What you should look out for when buying

In this guide, we answer the most important questions about buying a children's bike and offer you valuable tips to help you make the best decision for your child

The decision to buy your child's first bike or a new one is an important step. A suitable children's bike not only promotes motor development, but also boosts your child's self-confidence and makes family outings together possible. But with so many options to choose from, it can be overwhelming.

Why is the right bike size so important?

A bike of the right size is crucial for your child's safety and riding comfort. A bike that is too big can overwhelm your child and increase the risk of accidents, while a bike that is too small restricts freedom of movement and makes riding less fun. It is therefore essential to carefully determine the right size.

How do I determine the right bike size for my child?

The bike size is mainly indicated by the wheel size in inches. However, instead of relying solely on age or body size, you measure from the ground to the crotch and use these measurements to determine the right wheel size.

Why the customs declaration alone is not enough

The inch specification of a children's bike only refers to the wheel size and says nothing about the frame height, saddle height or the required crotch length. Your child's crotch length is the decisive factor in ensuring that the bike really fits.

While 12-inch and 14-inch bikes are ideal for beginners, while 16-inch to 20-inch models often offer more features. Larger bikes from 24 inches are already similar to adult bikes.

As a general rule: It is better to choose a slightly smaller bike so that your child can ride safely, rather than a model that is too big and difficult to control.

What role does stride length play when buying a bike?

The crotch length determines whether your child can safely reach the ground with their feet, which is essential for stopping and starting. A bike that allows your child to stand with both feet flat on the ground offers maximum safety and control

How can I ensure that the bike moves with my child?

Make sure that the saddle and handlebars are height-adjustable. This allows you to adapt the bike to your child's growth and extend its useful life.

Differences between children's city bikes and children's mountain bikes

Children's city bikes: Are ideal for everyday use in the city and short bike rides, as they offer a comfortable riding position, curved handlebars and often hub gears. They are characterized by comfort, good lighting and easy handling, which makes them the best choice for riding on paved roads.

Children's mountain bikes: Are designed for sporty off-road riding, with a sportier riding position, angled handlebars and derailleur gears for steep climbs. If your child enjoys being out in nature and wants to master challenging routes, a mountain bike is the better choice

What other factors should be considered when buying a children's bike?

In addition to the size, you should pay attention to the following aspects:

Weight of the bike: A lightweight bike is easier for children to handle and control.
Brakes: Reliable and easy-to-use brakes increase safety.
Frame geometry: A low entry makes it easier to get on and off the bike.
Adjustability: The saddle and handlebars should be height-adjustable to grow with your child.

Is a lighter bike always better for my child?

Yes, a lighter bike makes it easier for your child to ride, steer and stop. It reduces the force required and makes riding more fun. Models such as the 16-inch Kokua LiketoBike S Ocean children's bike weigh just 6.8 kg and are therefore particularly recommended.

Should my child learn to ride with or without training wheels?

Wheels can provide safety in the short term, but they prevent children from learning to balance. A better approach is to start with a balance bike and then switch to a bike without stabilizers. For example, with one of our RoyalBaby bikes.

How important are the gears on a children's bike?

Bikes without gears are recommended for younger children, as they can concentrate on riding. older children benefit from gears, especially when riding on hilly terrain. Models such as the Mustang Fury 24 have 8-speed gears and a suspension fork, which guarantee lots of riding fun even off the beaten track.

What safety equipment should a children's bike have?

A safe children's bike should be equipped with:

Reflectors: Front, rear and on the pedals for better visibility.
Lighting: Front and rear lights, ideally battery-operated or with dynamo.
Bell: So that your child can make themselves noticed.
Chain guard: Prevents clothing or body parts from getting caught in the chain.
