Product details:

From Wild Scooter Parts, this is the worlds first variable speed kit for Razor electric scooters. Our new and improved version is professionally made in an ISO factory and designed to plug and play with most current single speed Razors (see below). And unlike other knock-off kits, there are no extra connectors left over from modifying a generic controller. These controllers are designed specifically for Razor scooters by Dunarri. Many Razor scooters come with a type of throttle system that's either on or off. In other words its either at full throttle or zero throttle. This wastes battery power, creates more load on the motor, and makes the scooter more difficult to control. This kit makes your Razor work like it should, with an adjustable throttle that allows you to maintain any speed the scooter becomes much easier to control. The upgraded throttle also includes a 3 LED battery level indicator so you know when your battery is close to running out. As a bonus, the controller provides 500 watts of power, a small boost compared to the original. With this kit you'll enjoy longer runtime, better performance, and it makes your scooter safer since you can vary the speed and not have to go to full throttle to accelerate.
