Kunray 24V-48V 500W 25A Brushless Controller with LCD Display E-Bike Controller Dual-Mode for Electric Bicycle Scooter

I upgraded a 350w Kukirin M4 Pro scooter with this and cannot freaking believe all the speed and acceleration I was leaving on the table before this upgrade.I came from the KT or Kunteng world of controllers and displays and thought that I'd never switch because of how durable, faithful and the performance of them. I guess they've got competition...!!

Replaced the stock controller in my Freego ES-10 scooter with this and it was nearly plug and play with most all of the connectors just hooking right up where I needed them to. Has much better torque / hill climbing then the stock controller and performed quite well for the few weeks I've had it.I did end up using my stock LCD and throttle in the end because the one provided didn't have much of a throttle range. In the first gear it worked like an on/off switch with it going 7MPH no matter where the throttle was positioned. In higher gears it with take off hard and the slowest I could go was like 15mph. Luckily the stock LCD & throttle work perfectly with the controller and it will go from 3MPH to 30MPH smoothly in the top gear. It was pure chance that it worked, and for reference the old stock LCD I had was a PH02 / S5 which they offer with some of their 350W controllers so I figured it was worth a shot.First controller I received had an issue with the headlight output, it seemed to be stuck on all the time. Also the LCD that came with the first one had a twitch throttle with it kind of jumping around as you'd accelerate. Replacement worked as expected and the throttle was better with no spots that jumped in throttle response.Even though I got a defective controller on the first round the replacement process was easy and everything works great now so I'm giving 5 stars.

Well I have to give shipping a thumbs up. I got it 2 days earlier than the order had said(ordered Dec. 16th; delivered Dec. 19th by USPS.) However, I did get exactly what's described, and in the photos. I reused their own photos to help show that the display and throttle are a single attachment, and that there is a single 5 pin connector for the entire attachment. well, the controller has a single 5 pin connector for a display of some sorts and a seperate 3 pin connector to connect a throttle on its own. The instructions did not give details about which wires to use or if the pins needed to be swapped around or left along. I tried emailing them and they are not getting back to me. I even tried (for turds and chuckles) to get assistance from Amazon's help line and was told that I'd be referred to them and thery would email me back within 2 to 3 days. Just to top that all, since wire was not connected correctly, my 48V 17Ah Hailong style battery shorted out and it did some serious damage to cells, the BMS, main leads for Hailong mount and I am now out this $90 controller with display/throttle AND A BATTERY!!!!! Kunray you seriously need to step it up and make this right. I need a refund and then some. This post will be getting updates as I go down this gnarly rabbit hole of disappointment.

Almost all kits the screen, function buttons, and throttle are 3 different things mounted in 3 different places with 3 separate wires to run. This kit those 3 things are all in one with one wire. Very simple and convenient. Seller will comunicate and help solve any issues getting the parameters setup.

I bought this worked for 2 days then it said 07 error the wheel didn't spin, I will buy one last time if this second one doesn't last , you'll know the drill , if it last I will give 5star.

I had problems using mismatched a displays/throttle and controller for my e-bike. These two work perfectly together. Take some time to learn how to program the controller for your bike and the settings you want.
