    • Perfect set of training wheels.
Size: Universal 50cc Bikes
Absolutely perfect for a my 5 year old daughter. If you have any mechanical inclination this is simple to install and works great. Being universal, it should fit most gas or e-bikes. I installed it on a Jetson E-dirt bike and made it work as the foot peg holes are slightly smaller than the supplied hardware, so I just used some different bolts and she was riding in no time. ... show more

    • A must have for the 12E
Size: Stacyc 12e - 16e
These training wheels are an excellent addition to the Stacyc 12E model! They fit perfectly and provide great stability, allowing my child to gain confidence while learning to ride. The wheels are sturdy and easy to install, and they help keep the bike balanced as they transition to riding on two wheels. I appreciate the smooth performance, and my child enjoys the extra support. Highly recommend for anyone with a Stacyc 12E bike! ... show more

    • Perfect for Razor Dirt Bike
Size: Razor MX Bikes
This is my second time buying this item and it fits perfectly on my kids Razor Dirt Bikes. It has great traction control and allows my 3 and 5 year old boys to ride safely with their bigger siblings.

    • Heavy Duty/Easy Installation

I tried the training wheels that were specific to the motorcycle and sent them back to purchase these. For one, these mount to the pegs instead of frame bolts; if damage occurs that's a much more desirable location. Also, the bars shape allows you to control how much the training wheels contact the ground. This was helpful for me because my kiddo was riding in rougher terrain and the back tire of the motorcycle was getting lifted off the ground. By rotating the bar I could put more load in the back tire to prevent that from happening. Overall, the set is heavy duty. The only exception and reason I didn't give it five stars would be the smaller fasteners. The ones used to clamp the bar and prevent its rotation are pretty soft and one broke as I torqued it down. ... show more

    • Nice product! Fits and mounts easy.
Size: Stacyc 12e - 16e
Nice and sturdy, easy to mount. Adjustable ground clearance. Hardest part is bending the cotter pins, would be nice if they came with hitch pins instead,
