It's hardly been ridden and always stored indoors and at proper charge level for the batteries. 

Also note that they're 500W motors, which is higher than what's road legal in NZ. Despite that we have had customers install that sort of power range for other conversion kits. 

It was purchased outside of my company so they don't come with any warranty or spare parts, but they're at a very good price for what they're worth.
