The kit shipped quickly and customer service was great about answering my questions beforehand. The Kirbebike 72v battery was easy to secure to the downtube of the Ridstar, looks factory and is very solid and secure however it is not easily removed so don't plan on battery swaps. I was able to modify the Ridstar torque arms to accept the larger rear hub motor on both sides of the rear axle so we did not use the included torque arm. The controller fit where the plastic box on the Ridstar was and sits nicely in that space. All wiring was easily concealed and no problems with the connecters. The bluetooth dongle and app connects quickly and is easily updated. The display is clear and nicely laid out. Honestly this is a great kit to update a Ridstar Q20 into beast mode. The torque is fantastic and I am able to dial down the top speed through the app. The bike is super fast off the line. We ordered the "Surron" type throttle from Kirbebike but ended up re-using the "Surron" throttle my kid already had as it fit his bars better. The Kirbebike throttle was big for the bars on the bike and would not tighten properly. We did have to change the wiring order on the old throttle to match the new controller even though the connections were the same. Also be aware that there is a tarrif charge if shipping Kirbebikes throttle to the US. I still have to sort a tail light and brake light so I will be reaching back out to Kirbebikes great customer service to get that figured out. I highly recommened this kit.
Not clear that some controllers come with different and not enuff cables.
I found this Tongshen middrive easy to fit and install and works really well in use.I would have liked the display slightly brighter,as it has to be positioned carefully to be able to see it clearly and in the settings it's on maximum. For a newby,better instructions are required as they are sparse at best. Really impressed with it's operation in use,bafang needs to up it's game. Would buy another.

Poor, customer service also dire, the battery wasn’t compatible woth my kit so i asked to return it, more than happy paying postage and all that however because i had plugged it in to find out it didnt work they have stung me for £80 as a partial refund because its been “used” they are a con there are plenty of other ebike sellers out there. use them instead of these people
Thank you for your feedback. To clarify: the battery had been used for about a week. In your own earlier message you confirmed your Bafang BBS01B had been "hacked" (no longer a 15A controller), and that the battery was cutting out on the BSM while riding — which shows it was used and could not be resold as new. We offered a partial refund rather than refusing the return, which we feel is fair.
We're always willing to help our customers; please contact us directly if you'd like us to look into anything further.
So it came a week after I ordered it and all went fine with the assembly but when I started riding the bike there was a noise coming from the rear wheel so went to my local bike shop and they said a lot off the spokes were lose, got them tightened and all is good now.
Smart eBike Controller with App Programmable Settings
It is genuinely so awesome and so fast. Difficult to install and could do with some more accessories to help with it and it could have better range but other than that it’s perfect!
Working OK and quality is very good

Very happy with product
Great kit, comes with everything needed, but cannot connect with the ride power app, so the bike feels limited to standard features, I guess to keep it legal, but I’m using off-road…. Please help

Installation booklet could be written a little better. Some parts were too small for the handle bars and frame. I know it’s hard to make parts fit hundreds of bikes, but you can make parts a little larger and put spacers in. I have rode it for 20 miles, could have used more power and speed. If you want close to 40 mph go at least 2000w. I’m close to 200 pounds, when I ordered I should have took that into consideration can only get 28 mph my fault.
After discovering my controller does not work customer support helped me schedule a return in order to gain a refund
Worked fine with 72v 60a bms battery but reads over volted with cyc-a65 battery even tho it has 130a bms. I believe they are helping to find out why this happens. No point using the 100a for 72v with 60a bms unless they sold their own higher power battery supply
Ordered 2 kits bith with batteries.
Took a little longer than anticipated to arrive but did eventually. Instalation is fairly simple but just be mindful of the bike you are putting them on. We installed them on mid range trails bikes and after a few little tweaks they went on. Things to note. You WILL need to upgrade your chain to an ebike one.
Our bikes were both 12 speed and we are unable to use the first 2 or 3 gears as there is too much of a stretch on the chain so really is better suited to either 9 or 10 speed bikes.
Overall performance has been excellent, very punchy motor and hitting 100kms on a full charge exceeded our expectations so awarding 5 stars
Just put the EZ Kit on my bike, and honestly, it absolutely lives up to the name (EZ = Easy). The installation was incredibly smooth, no faff at all. The dual battery setup is spot on—easily getting around 60 miles from it, so I can just enjoy my weekend rides without constantly staring at the battery gauge. You’d think a twin-battery setup would feel bulky, but the kit is actually surprisingly lightweight, and the bike still handles as naturally and smoothly as before. Genuinely a cracking, well-made bit of kit!
