12V-72V E-Bike Universal Thumb Throttle LED Digital Display Voltage

We have these installed on 2 upgraded scooters and they work great. Durable and precise with their power management. The wiring was not plug and play for our scooters, but I was not expecting it to be when I bought them as I was upgrading the battery, motor and controller on our Razor e300 scooters to be the fastest scooters in the neighborhood. Success and smiles!

Pretty cool, got to say the cord is long enough for multiple different scenarios, functions as described

Zero stars, bought to fix my child's gocart before there birthday. Didn't arrive in time for one, and was doa for second. Had a replacement sent, next day got it. Same as the one I had dog, no signal for one, sensor bad throttle wide open on the other. Do not buy, its 0 for 2. Will not buy again.

Worked for me. I had to switch the red and green cables to match my harness. Works as expected. Quality doesn't seem great but it's to be expected for the price. Will update this post if it fails.

EASILY helps me hit 37mph on my homemade electric mountain bike! Plus it lets me keep a way more accurate eye on my remaining battery amperage via voltage gauge (fully charged my battery sits at 58.2V 30Ah, bike starts to slow down hours later when I reach 50V). It's also a lot lighter and less fragile than the old twist throttle that originally came with my control unit. In addition, it also lets me turn off the throttle with the flip of a switch which then let's me safely recharge the battery slightly while stopping (my controller allows for the recharge feature, the switch on the throttle just makes sure I never give it gas by mistake).

Are you kidding me, how can this cheapy China plastico dare ship without a single bit of usable information on how to connect it. Why even install a connector when a good portion of users will need to remove the connector and hard solder the thin threadlike wires to their existing controller... Hey have they considered adapter plugs.... Could save us hours of aggravation! How about wire clams or screw downs with suggested tips on what wires we are trying to hood up to and what the wires are actually for. Heck they do not "do" standardized colors in China, so you would think that it would be consider extra important to indicate what the wire is for and where you should be attempting to connect it to.... If you know the colors may NOT match, SAY SO! Then use A B C D E F or the throttle, switch and display, and use 1,2,3,4,5,6,7,8,9, etc for the controller, maybe mention what colors they could be or most likely are, then tell us how we are to USE the device correctly and confidently making the connections. Goodness Gracious! MarkMannM2

It caught fire. The throttle never worked I got second and it worked great

wish it came with a wiring diagram, but we got it figured out.

Good product works great and is very useful
