2-Speed Auto Shift Rear Wheel

Looking to add some speed to your little rider's Alpha One or Alpha Two?  Our new auto-shift wheels will give your rider a 37% boost in gain ratio.

This wheel contains a two speed internal hub. At speed the hub automatically shifts into a higher gear, giving your little rider a 37% speed boost.

The kit includes an entire rear wheel.  Installation is simple: (1) remove your existing wheel, (2) swap your tire and tube from your existing wheel onto the auto-shift wheel, (3) install the auto-shift wheel.

The 2-Speed Auto Shift Wheel is not compatible with the Zulu One or Zulu Two.
