Best scooter upgrade
I love this upgrade to my grand daughter's scooter, Its very easy to install and works just like the advertisement says. It gives you more control over the speed and increases the usage time. Anyone who has a single speed scooter must buy this upgrade to get more enjoyment out of their scooter. Thank you for a great product.Read full review

great product for the money
works as described. The instructions are very easy to follow. Great addition if you are looking to control speed a little better. I also added the speed controller so i could dial it back for my 6 year old. He runs it about 7 mph max and was able to learn how to turn and take off alot easier.Read full review

Great addition to a older scooter
Put this on an old Razor 150 with some new batteries and it’s a brand new toy. My daughter loves it and the variable speed makes life easier for a younger rider.

Works as advertised and relatively easy to install
Kit installed relatively easily in the E100 scooter I bought for my grandson. The new controller was a tight fit in that it is about 50% larger than the stock controller, but it does fit. I also installed the max. speed reducer. That item was easy to install and it works, but it is very sensitive. Once you tune in the "sweet spot" on the control, a small change in the max. speed control makes a big change in the actual max. speed.
Bottom line is the kit works as advertised and is relatively easy to install.Read full review

Great kit, my son loves it
Awesome little kit. Worked exactly as described and fit perfectly, after a couple of attempts at packing it in. My son loves it. Makes the scooter much easier to control. I also installed the speed limiter to slow it down, it also works great. The instructions were clear but the install might be a bit scary for those not mechanically inclined. Fortunately, the connections are marked and there is a number to call if you need help.Read full review

Much needed after-market enhancement to the Razor scooters
We purchased the Razor electric scooter for grandkids 8 - 14 years old. All Razors seem to come only with an on-off switch that they call a throttle. The full power on position is too fast and scary for young riders. Fortunately, we found the variable speed throttle after-market product that solved that problem. The installation was straightforward, but the compartment where the electronics go is quite tight for the larger control module. I am surprised that Razor doesn't provide this type of variable throttle with their products. Read full review

Good product and son was happy!
Easy to install. It was as described.
Pictures with the instructions would have been helpful but everything was clearly labeled.

Great product and great value!
My son loves this! He complained about the factory throttle hurting his hand and this replacement did the trick!

I bought the E100 for my grandson, It was to fast and started to fast. I installed the speed controller and hand throttle works grate. Recommend watching the You tube instruction video first.

Dont be intimidated, just follow the instructions and if you are handy, you can do it.
I also used the variable speed kid and it worked exactly as expected.
