MIMIRACLEScooter Throttle, Accelerator for Niu KQi2/KQi2 Pro/KQi3/KQi3 Pro Electric Scooter - Speed Control Thumb Throttle Replacement with Waterproof Plug

Loosening the four bolts makes it easier to remove the plastic cover. This accelerator appears like the original. Works great with no issues. Great value and easy to replace.

Suddenly my NIU KQI2 scooter stopped while riding home and said error 3. After using the app found that it meant the accelerator was having issues. Was not sure what to do and googled and found Amazon had the part. Got this and it arrived quickly and I installed it and now it works perfectly again.For installing I took off the front panel (plastic and metal piece) on the front of the head unit (above light) and that exposes a hole. Using a knife I gently popped the plastic off the display (seems it is glued or stuck to it). The main display has like 3 small screws after that it came out and all the cables inside were just plug and play style. Found the one to the old throttle and unplugged it and pulled it out (take out the rubber cable plugger). You may have to cut the zip tie and take off the black thing covering all the cables. Once done I put it back and zip tied it back. Put the new throttle on and ran cable in. Once lined up with the hole on the front I pushed it through using a hex wrench (gently push; it does have to line up right). But once in pulled in some of the excess and plugged it in. It clips in easily. Put it back together (be sure to tighten the three screws holding the display board properly. If too loose the button won't work right. I put a small dab of glue on some parts of the plastic and pushed display back down (it was still pretty sticky). And put it all back together and all worked. Found some YouTube videos as well which are super useful! This saved my scooter!

Easy to install and perfect fitment

It’s about the same price but the funny thing is I contacted NIU’s customer support and ordered this at the same time. By the time they responded I had already received and installed the Amazon one 💀

This Mimiracle throttle is intended for use with NIU scooters but I adapted it to work with a generic 36 volt controller and motor. I believe the wire connector included with the throttle is proprietary (at least it is different than similar connectors I have seen) but it will work with a generic 3-pin PH2.0 (white) connector. The only drawback is the connector will make full electrical contract but it will not lock in place with the locking lever. I simply secured mine with black tape and it holds together fine. Throttle tests just fine on a multimeter and operates a 36v volt controller without any issues. I took one star off the review because, at $15, it is not a bargain priced scooter throttle. But if you need it for the intended NIU scooter then the price makes more sense since it will fit without any issues whatsoever.

No sé cuánta garantía tendrá este acelerador pero por ahora volvió a funcionar la patineta

Exact replacement for

The media could not be loaded. It took a couple of days, but it's worth it. Awesome fit. I have a NIU KQI2. I highly recommend it.
