[Durability]: Exway Wave Hub vs Belt

Hey guys,

Been riding my Exway Wave Hub for a few years. Overall very happy with the board but my hub motors have picked up rust along the way and I can feel that they're nearing the end of their lifespan.

Question for you all: If my main concern/wish is durability, am I better off with another hub - or belt? I read the belt drives are more maintenance. That I don't mind too much but if that also means that they are more prone to breaking down in general, it'd be a No.

My main gripes with the hub version so far: The sleeves ride down very quickly so have had those replaced a few times (with expensive shipping from China), and the motors have definitely taken on some rust (never rode in the rain, but going over the occasional puddle did it probably).

I don't care about torque, the hub is plenty for me. But also read the belt can be more easily replaced. So which version would you go with??

thanks!
