Encoder Wheel w/ Knob & Arm

Will only work if their bike already has a pig tail which is supposed to be any bike made after 2020. 

Just because the SKU sheets says it will work for an EX1 or EX3, does not make it so, they bike still has to come with a pig tail in side of it. 

Currently the Interchangeable Parts sheet does not say it will work for an EX5s series (03/16/2026).
I am not sure why, again as long as the bike has a pigtail it will work for the bike.
We are working to get this sheet updated.
