You are only buing a Twist N' Go throttle display as pictured.
 
This will work with our 'Commuter' model, the Sealup Q18 and other electric scooters but please keep in mind that it's your responsibility to check and make sure that it will work with your scooter, before buying it.
 
There are no instructions on how to fit them so if you don't know how then we suggest that you seek for professional help for it.
