The part that came was the controller . I lost two previous keys ?? very easy. I don't like putting things together but this was too easy. If I can put a picture I will.

Fixes the issue

Definitely a great scooter and good value for money.
Very powerful and actually pretty easy to ride when using self-control and not overstepping your own ability, as this scooter will accelerate to virtually any speed you want.
It is essential to use self-control to keep yourself safe. Having said that, the other side of the coin is that the power this scooter possesses also makes it safer because you can zip away from traffic coming up behind and quickly duck into a safe hiding place on the side of the road, out of the way from cars speeding up from behind.
I prefer the thumb throttle and would also recommend mounting a rear vision mirror, as well as wearing gloves, enclosed footwear, a hi-viz vest and a full-face visored helmet. Overall: Great and comfortable scooter, fantastic feeling riding it.

Exelente me lleg mi pedido super ahora puedo pasar feliz muchas gracias

Needed the repair to repair a scooter. My only complaint is there is no way to tell what plug goes into the throttle and what plug goes into the harness. Ive toasted one display accidentally swapping them.

I have a D4 3.0. After just a few weeks, about 50 miles, it simply would not turn on. Key switch indicated full voltage. I ordered a new display and three button switch. The new display fixed the problem.

Great product, i will recommended it

It went well. I would recommend having more online resources for troubleshooting and repairs. For many individuals there are not any repair shops nearby and they must repair them themselves. By having access to different information on your scooters they can order the correct parts without having to spend hours searching the internet for answers.
