The only way to accomplish top speed adjustability would be to install a variable speed throttle and controller along with a throttle top speed adjuster which we carry. The cost for all of these parts would be around $45 through $50.
If you are interested in making the scooter variable speed with a top speed adjuster then please let us know and we can figure out and let you know what parts would be needed.
If you are interested in a plug-and-play kit then please let us know the version number for the E100 scooter so we can design it for that version.
The version number is located on the ID tag which may be found on the battery charger, battery box, handlebar stem, bottom of the scooter, or other areas. ID Tag Locator
So I made the mistake of just purchasing the item # THR-ADJUSTER thinking I could use it by itself, but based on what I just read in this thread, it appears I may need the Plug-and-Play kit you described to make it variable speed.
If I send you the number off the Razor can you assemble one of those for my scooter??
They are not difficult to install, however, installation requires replacing both the throttle and brake lever so it is not a 5-minute job either. One person who installed two of the kits told us that it took one hour to install the first kit and half an hour to install the second kit. So the amount of time it takes to install the kit depends mostly on the installer.
Here are links to the kits:
Thanks for your request. We went ahead and made variable speed kits for the Razor E100 Version 1-7 electric scooters.

We have this one. Razor 13111260 E100 Electric Scooter (Red) https://www.amazon.com/dp/B000BYCC0G I didn’t know there are different versions. I ordered the 16+ a couple days ago. Is this the right one?
The chances are extremely high that it is a version 16+ since it is a brand new scooter. You can confirm that it is a version 16+ by looking at its ID tag and reading the two numbers between the dashes. These two numbers are the version number.
You may want to try wrapping the extra lengths of wire together with zip ties to make it more compact and to keep it in place while the footplate is being installed.
We now have variable speed conversion kits for Razor E100 electric scooters (version 16 and up). They are available both with and without throttle top speed limiters.
I'm trying to slow down an E100 electric scooter with some sort of variable speed controller. We bought the scooter for my daughter but it seems to be a little fast for her at the moment so I figured that if there was some sort of variable speed controller with a dial I can increase the speed a little at a time as she gets more comfortable.
the kickstart feature doesn't bother me so I really don't want to change the throttle unless I have to.
