Sur-Ron Light Bee 4-Pin Jack Shaft Tool

Whether you call it a Mid Shaft, Jack Shaft, or Intermediate Shaft, if you are performing maintenance or upgrades you will first need to remove the stock castle nut. This 4-pin tool from DirtyBike works with a 3/8 ratchet to get that pesky 4-prong nut off easily.

Once removed, consider replacing the stock nut with a DirtyBike standard nut which can be easily removed with a normal socket. 

Please note the mid shaft nut on E Ride Pro bikes is not the same as Surron Light Bee. If you have an E Ride Pro, this is the tool for you.
