Step 1

To begin the process of installing training wheels, you need to first use the adjustable wrench to loosen the bolt on one side of the rear wheel. While doing this, hold the bolt on the opposite side with the other wrench so as prevent the wheel from spinning. After the nut is out, place it on the ground taking note of the direction the bolt was facing on the hub.

Step 2

Align the training wheel hole with the central bracket where you removed the bolt before ensuring that it fits well. Also, ensure that the axle end has enough space to fit both the training wheel and the bolt when tightening back.

Step 3

Slowly attach the bolt again and using your hand to ensure that the thread fits well. This will make it easy for you to do further tightening using a wrench.

You can estimate this measurement by placing shims under the two wheels. This will ensure that they are equally raised from the ground. The shim can be objects such as a piece of wood, stone block or a book. This is provided that the two pieces have the same thickness.

Step 6

Once you achieve the right height for each training wheel, you should use the wrench to fully tighten the bolt into place. Secure the wheels by putting the right amount of torque on the bolts.


After installing training wheels, it is important to perform periodic inspections from time to time. At least once every month, you should ensure that the bolt on the back axle in place is tight and secure. And the training wheel clearance from the ground must be the same on the both sides.

  • Unwind the nut on the rear axle and set the right ground clearance on both training wheels
  • Finish by tightening the axle wheels.
  • As the child grows, you should increase the height between the training wheel and the ground. This should however be based on the kid’s skills in balancing and turning.
