How do you not lock the seat? It locks when you put pressure on it & I assume you sit on the seat at some point..I solved that problem.............!!!!!! I just never lock the seat - EVER!
Mine hung up one day when I ut my jacket & helmet under the seat and the jacket, even though mesh, too up too much room.. I had visions of a ticket because I would be riding without my helmet.. finally it popped when I turned the key.. whew !
