When it comes to assembling the hardware, which is, of course, our next step, the first thing we require you to do is to check if this hardware is already pre-assembled. That is, if you’re lucky, they may get delivered to you pre-built. However, if they aren’t, you don’t need to worry much about that because assembling the hardware isn’t difficult.

This question isn’t a surprising one. Most people who want to get training wheels are often skeptical about how effective they are and what they do exactly. If you have a young child that wants to learn how to pedal and stay upright on a bike without getting injured, yes, get them training wheels, and you’ll be glad you did.

However, you should know that training wheels do not train kids to ride a bicycle in the real sense. And, if this is the reason why you want to buy them, probably because of the word “training” that precedes the wheels, you may want to reconsider your decision. Reiterating just for your better comprehension, training wheels help your kids enjoy better balance while they’re in the process of learning to be great riders.

If the instructions are not available, you may contact the manufacturer directly for assistance or visit a bike shop for professional help.

Bikes with Gears

The process of installing training wheels on a bike with gears is similar to other bikes. Firstly, you will need to find the right training wheels that fit your bike’s frame and wheel size. Secondly, attach the training wheel brackets to the rear axle of the bike and ensure they are securely fastened. Thirdly, attach the training wheels to the brackets and adjust the height of the wheels as needed. Finally, check the stability of the wheels and make sure they are secure before riding the bike.

Adult Bikes

Yes, training wheels can be put on an adult bike. While training wheels are typically associated with children’s bikes, they can be used by adult riders who are new to cycling or need help balancing. However, it’s important to ensure the training wheels are compatible with the frame and wheel size of the adult bike. One of the best adult training wheels are Bike USA Stabilizer Wheels which will fit 24″ to 27″ wheels.

Mountain Bikes

There are trainer wheels that are compatible with mountain bikes, but it’s important to check if the training wheels are designed for mountain bikes, as they have specific requirements such as strength and durability to handle rough terrain. If in doubt, a bike shop can offer advice on the best training wheel options for a mountain bike.

Balance Bikes

Training wheels cannot be put on a balance bike like the one from Milazo. Balance bikes are designed to help children learn how to balance and ride a bike without the use of training wheels. The idea behind a balance bike is that a child will learn to balance by themselves without the support of training wheels, so they can transition to a regular bike more easily. The addition of training wheels would defeat the purpose of a balance bike.


At what age do kids use training wheels?

Training wheels are designed to be used by kids of different ages, and they’re available on bicycles of diverse sizes. If your child is within the range of three to eight years, you can start training them to ride a bike and introduce training wheels to make the learning experience better and more relaxed.

More so, you should endeavor to put the age peculiarity of your child into cognizance when you’re buying a bicycle for them, and the training wheels should as well be well-suited and well-installed. If your kid is a bit older, getting a nice suspension seat post would be thoughtful if they often complain of lower back pain.

Can you put training wheels on a 20-inch (50 cm) and 24-inch (60 cm) bike and how to do it?

When it comes to attaching training wheels to a 20-inch or 24-inch bike, there are some peculiarities that you must take note of. First, some 20 and 24-inch bikes require specialized training wheels, and there as well some of these bikes have a rear axle long enough to make them suitable for training wheels attachment. Several 20-24″ bikes can have training wheels attached to them, but these wheels are not attached to the axle but the frame for some bikes.

How to adjust the training wheels after they’re fitted?

Training wheels are not designed to be a one-size-fits-all kind of thing. That is, you can choose to make temporary adjustments when you feel your kid isn’t too comfortable while riding. When adjusting training wheels, you don’t even have to remove the training wheels and then start installing them all over again. You can choose to lower or raise them or any other things that work to make them more relaxed. And yes, the adjustable wrench or a correct-sized wrench will do the adjustment job.

The frame is attached to the wheels with the nuts, and you’ve to get them loosened with the wrench. Once you’ve done that, you can proceed with your adjustments and see if your kid is finally comfortable with the position this time around. Nevertheless, it would help if you did not forget to tighten the nuts again.

How should training wheels fit on a bike?

Training wheels should fit securely on the rear axle of the bike, be parallel to the ground, and not wobble after proper attachment and height adjustment. If the training wheels still won’t fit properly on the bike, consider looking for alternative training wheels, visiting a bike shop for professional help, or purchasing a different type of bike that is compatible with the training wheels. Avoid DIY training wheels to prevent any accidents and ensure safe use.

Final Thoughts

Serving to prevent accidents and maintain balance, these wheels can be attached to the rear wheel, and they’re also referred to as stabilizers. However, even though training wheels are often used for kids learning how to ride a bike, adults can also benefit from using them because adult versions are available. To include, you’ll find the training wheels to be very effective if you’re riding in a flat driveway or a wide sidewalk, and if you reside in an area with no hill, you’ll find them to be a very suitable option.

Without mincing words, knowing how to put training wheels on a bike can be very profitable, and you can always introduce these stabilizers to your kids when they’re in the bike-learning process.
