Sturdy Material: Kids bike training wheels are made of high quality ABS wheels and high quality metal. Bicycle auxiliary wheels are durable, non-slip, wear-resistant, provide stability, help children ride bicycles, and let children enjoy the fun of cycling.

SAFETY AND ASSISTANCE: Your child's safety is our top priority. Heavy-duty training wheels help beginners maintain balance and provide greater safety and stability until they learn how to ride a bike. No need to hold the saddle, you will keep your child safe.

UNIVERSAL SIZES: Our Kids Bike Universal Assist Wheels fit 12 14 16 18 20 inch kids bikes and meet the needs of kids learning to ride when they grow up. Please check if these wheels are compatible with your bike.

Flash Design: Our toddler training wheels are non-slip and noiseless. Especially with the flash function, children are more interested in night riding. Bicycle stabilization wheels are a great help for your child's first cycling lesson.

EASY TO INSTALL: The 20" training wheel kit includes two shoulder bolts, two nuts, two washers, spacers, two vertical support arms and two wheels. Mount the training wheel on the rear wheel of the child's bike with two wrenches to adjust the distance from the vertical stand to the ground.
