M8 x 1.25 Children’s Bike Axle Nut Adapters

The FollowMe set comes with the 5/16 and 3/8 axle nuts. The axle nuts on children’s bikes can have metric or English threads. These sizes are very close to each other making determining the right size sometimes difficult. To check the size, you can measure the inside size of the axle nut currently on the child’s bike.

This adapter has inner size: 6.7mm. Visit a bike store if you cannot measure this yourself with a caliper.
