Compatibility, Size and Fit
Fit is the main decision point for this product. The bicycle needs to be one of the listed wheel sizes, use a single-speed setup, and have enough rear axle extension for installation. The rear axle extension is stated to need to exceed 0.4 inch.
After installation, the bottom of each training wheel is stated to sit within 1 inch of the ground. That clearance is part of the setup check, so the bike should be measured before purchase if fit is a concern.
What Else You May Need
A compatible bicycle with a single-speed setup is required. If the bike has derailleurs or the rear axle does not extend far enough, this set is not the right match.
Before You Decide
Confirm the bike’s wheel size, single-speed setup, and rear axle extension before choosing an offer. Also check the 80 pound rider limit and the ground-clearance requirement so the fit matches the bicycle.
