1 Pair EBike Throttle Grip, Universal Electric Bicycle Scooter Twist Handlebar with LCD Battery Voltage Display Key Knock, 12V-84V Electric Bike Throttle Grip for Motorbike Motorcycle E-Bike

Our kids bike speed sensor part that rotates on handle broke so this speed sensor fit the bill. I had to modify some wire since they weren’t an exact plug and play, but it worked just like the original once installed. It looks nice even though it was red and the original was just black, but for the price it is a great value and nice quality. It was a slow process matching the wires but once you figure it out, it worked perfectly.

I haven't used it yet but I did install it on the handlebars. It looks great, seems to be very good quality, definitely an excellent value if it works as it's supposed to which I assume it will.

Throttle accelerated by itself had to turn off key switch to stop e-bike. It was very dangerous. Then the throttle no longer worked. Lasted 2 months.

I installed this throttle with LED display on my Razor MX650 and it works perfectly, but figuring out the wiring was tricky. My original throttle had a 6-wire harness, and this one has only 5 wires—with color codes that don’t match up exactly.To ensure I understood the factory wiring diagram, I checked the version number of my MX650 using this site: Electric Scooter Parts – Razor MX650 Parts.I compared that wiring to a Facebook (Google “ razor mx650 throttle wiring Michael Kwok”). He shows a photo with the words “blue,” “yellow,” and “match” that made it all make sense. This shows exactly how to match up the wires between the OEM wiring and new throttle (that photo is also attached here).The LED display is a nice upgrade and the throttle response feels solid. Just be prepared to do the above research and you’ll be good.

Throttle works great. I'm a little disappointed that the led voltage doesn't work. I could tell by the way the wires were wrapped that this had been returned before. After cutting and soldering this into my scooter, I'm not going to replace it due to a bad led readout as my scoot has a battery gauge on the main screen. If this has been returned before, and it surely has you would think it would at least be tested to be sure it is in working order.

Works very well the hub motor i have and display the voltage proficiently, its a must buy item.

They really dress a bike up and I love being able to see my battery fuel gauge in bolts whenever I need to check it. I build my bikes from scratch and it’s the only instrumentation I really have. I don’t bother with Speedometer. - wise man troubles with your appropriate speed based on his surroundings and the traffic moving with him other than that, you’re usually going as fast as the biking allow that’s all I need to know hah. I think they make fair statement for the protection my bike was stolen once and the guy that brought it to a bike shop near here so they needed to get a key for it even though I hadn’t connected it yet and it worked fine without the key if you knew what buttons to press. Luckily, I had an apple tracker in the bike and got it back.. It’s not a total deterrent, but I think it does make the bike look like more of a pain in the ass to steal. The three in one nature of this makes it a great value and again they look great.

Really good quality and worked exactly how i wanted it to!
