3/8 Children’s Bike Axle Nut Adapters For FollowMe Tandem

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 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 dimension: 8.5mm. Contact us if you cannot measure this yourself with a caliper.
