Main highlights- 【Wheels Light Up】The light will light up in the dark. Children definitely love the lights that can give them a beautiful world of children. You will see the smiles and the joy on the children's faces
- 【Thicker Bracket, Stronger and More Durable】Have you ever encountered a deformed or even broken bracket of a training wheel that caused your child to fall badly? Please don’t worry. With that in mind, we designed a heavy duty training wheel with bracket at 0.12 thickness that is 20% thicker than regular one, which exerts a stronger support capacity. Thus, it’s not easily deformed or broken. Your kid will be safer with confidence while luxuriating in learning to ride a bike
- 【Installation Prerequisites】To leave sufficient space for installing the training wheel brackets, please ensure that the visible length of the studs on both sides of your bicycle's rear wheel is at least 0.4 inches.
- 【How to Determine the Size of a Bicycle】1.Confirm the size using your online shopping records. 2.If there is a marking like "Tire Diameter" × "Tire Width" on the bicycle tire, the tire diameter corresponds to the bicycle's size. 3.If no such marking exists on the tire, you will need to measure the tire diameter to determine the bicycle's size. Please select training wheels that are 12 inches to 20 inches in size, based on your bicycle's model.
- 【Easy Installation】As shown in the video, equipped with 2 wrenches, the installation can be easily completed. The locking brace is of an assistant for securing the bracket and bicycle. Couldn’t be more simple! Meanwhile, we recommend the training wheel for boy and girl should be about 0.5 inch away from the ground when the bike is standing upright, which can benefit your kid's sense of balance in riding. If you have any issue, please feel free to let us know. We'll do our best to help you.
- 【Double Bearing and Larger Washer】After optimization, the double high carbon steel bearing of our training wheel has been tested to be silent and smooth, with longer wheel life. In addition, we have specially enlarged the washer so that it can cover the whole bearing nicely. So even after your kid has ridden for a while, you don’t have to worry about the sudden drop of the bearing, which may cause your child’s sudden falling to ground. Ride safely and grow up freely
- 【Best Gifts for Kids】This training wheels are very popular with boys and girls, that is one of the good gifts that will continue to bring joy to kids. If you want to express your love for them choose it!
