The Most Popular 12-Inch Bikes for Kids

A bike is the ideal choice for developing your child’s agility and coordination. It also helps to increase concentration and independence. It’s also a great opportunity to spend time outdoors and enjoy the fresh air. Protecting your child should always be the focus of all these points, which is why we have provided you with an overview of important tips.

What You Should Look Out for When Buying a 12-Inch Bike

Here are some tips to consider when buying a bike for your child to make sure it is safe and reliable:

  • Size: Make sure the bike is the right size for your child. A bike that is too big can be difficult to control and a bike that is too small can be uncomfortable and difficult to ride. ᐅ Children’s bikes with 12 inches are usually suitable for a height of 95 cm or more.
  • Portability: A lighter bike is easier to handle and should also be easier for the child to ride.
  • Front and rear brakes: It is important that the bike has reliable brakes so that your child is able to brake quickly and safely. Hand brakes are therefore just as important as coaster brakes.
  • Tires: Make sure that the wheels are in good condition and have enough tread so that the bike grips well on different surfaces.
  • Seat position: The saddle should be adjustable so that your child can sit comfortably and safely.
  • Reflective features: It is important that the bike has reflective features to make it easier to see in the dark.
  • Training wheels: If your child has previously ridden a balance bike, training wheels are usually no longer so important. However, training wheels can be a huge help when your child starts cycling for the first time.
  • Children’s helmet: One of the most important things that is unfortunately often forgotten. A helmet for your child is essential and contributes enormously to safety when cycling.
