So, we got this in the mail today. Took about an hour to get everything hooked up. Hardest part was getting the grip and the throttle onto the handle bars. It was extremely tight. Had to use a hammer and some WD-40 to force them on. Other than that, everything snapped together and my son was off and running. He's thrilled with the variable speed throttle, and the battery charge indicators. Now on to a funny story. When i first unpacked the controller, i was comparing it to the old controller and notice there were two single red wires missing. I was about to call up, and suggest they sent me the wrong controller. My son (12 years old) was asking me what those connected to. I said they connect to the power switch on the bottom. He goes, oh, we don't need that anymore, cuz we have the key which turns it on and off. Haha, 12 year old debugging my stupidity.Read full review

The throttle is not a throttle, it is an on and off switch. Its' full power or no power, so it is excessively jerky to ride, impossible to ride comfortably along with someone on a bicycle I have to just jerk along and coast jerk coast jerk coast. Penny wise and pound foolish, they probably could have added a veritable speed throttle for another $5 in production costs. This foolish oversight ruined an otherwise quality product.

The best thing about the kit is it adds actual throttle control. Technically a variable speed motor controller. Makes it a lot easier to ride. It give the scooter a true "throttle". It is easy to install with a screwdriver, a pair of pliers and an allen wrench kit. The wiring is plug and play. It really couldn't be much easier. The new throttle is smooth and linear. I opted for the keyed "ignition" switch. Love the LED power monitor. If you have a Razor E-300, you need one of these! 10/18/19 I have had this kit for going on two years. I have it in a 3 wheel conversion E300. I constantly use it on job sites and shopping. A 9 year old boy and 10 year old girl ride it around the shop all the time, sometimes both at once. Performance has been flawless. Do not hesitate to use this kit!!! I am powering it with 24 volt Kobalt drill batteries. (two 4ah in parallel) Much better than the stock 7ah stock batteriesRead full review

Razor makes a great scooter but for some reason they only offer a throttle that is either on or off. The scooter is nice but you don't always want to go full speed. I saw a few different model Throttles available but decided to go with this one. This Throttle not only allows you to easily control your speed but it also lets you know how much battery life is left. Before having this Throttle you would have to guess how much time you had left but now it lets you know when the battery is going low. There is only one improvement I would like to see and that is instructions, there are none. That being said, it is simple installing this. All you have to do is: 1. Take off the running board. 2. Disconnect all the connections that go into the controller (the silver box) and on off switch (if you got the key ignition which I would suggest, great feature) 3. Remove the existing Throttle (using a Allen wrench to loosen the throttle) and slide the new Throttle on. When you remove the Throttle cable and install the new one, there is a split gasket that will allow you to easily remove the old cable and run the new one through it. 4. Connect all the wires to the new controller box (all the connectors are the same as the original so there is no guess work). 5. Put the running board back on and you are ready to go. This only takes 20 minutes to do the entire install and is pretty easy. I would buy this product again.Read full review

Was a very tight fit and no instructions included (only online) but worked well. A little creative imagination is useful to help with re routing of the throttle cable. Will need Nylon Ties (not included). Fit is a bit of a struggle with the batteries and cables. Can not use mounting screw or brackets. I put some rubber inner tube on top of everything so when I closed the hood nothing would rattle. It was good idea. The manufacturer (Razor) should be shamed for selling something like this (Throttle totally on or off). This Scooter E300 should come stock with this new variable speed setup.
