This kit is the best. You couldn’t get much better than this. Other controllers I have used and motors I had would frequently burn up regardless of what I did to help cool them down. This controller and motor run so smooth and do not overheat at all. I have about 5 miles on it so far and have not had one issue yet. The controller is fully programmable through the lcd display and is very easy to understand. The wiring is very easy to understand as most all of the connections only have 1 possible connector they go to. Can’t really mess it up. As for the power, oh boy. This baby moves. With myself and batteries on this aluminum frame 26” mountain bike at approximately 250 lbs, I can easily do 33mph the entire time. The battery size and amperage output does play a big part in power and speed of the motor so make sure you have the correct battery. The more AH capacity, the faster you go. Now for the customer service. Anne has been a huge help. She was very fast to reply to emails and then to messages on what’s app. If I had any questions she always provided me with as much information and help as she could and was always so friendly. I haven’t dealt with someone so pleasant is so long, it was very enjoyable, refreshing, and just made me feel appreciated. If your looking for a project or parts, this is the place to get them from. The shipping times don’t always reflect the actual ship time. I got my kit in about 1 week. When you make your order, Anne will get ahold of you and verify your exact parts and anything else that you may need so when you get the kit, it is a direct bolt up with as little to no modification needed. You really couldn’t make it any easier. Thank you very much Anne for all of your help and I look forward to being able to work with you again in the future. Update time!!! It’s been 2 riding seasons now, after battling some battery issues and increasing battery capacity, I have found that this set up will actually do close to 45 mph without pedaling!!! Which is insane on a bike and makes you want more. I am still super satisfied with the capability of this motor and controller. It works so well it leaves me wanting more. However to much more and I’m afraid I may burn it up. Always keep power ratings at their rated level and don’t try to over run the system. If you want to go faster get the higher rated system. I have close to 600 miles on this system so far and am planning on building a side car to take my son with me to work during the spring and summer. I plan on running this set up for many years and if anything ever happens to it, I wouldn’t hesitate to buy another, however next time I may buy the higher rated system and really see what it can do. Remember however, these are bicycle parts. Most bicycles aren’t built to go that fast constantly. Take care of your bikes and make sure they are safe to travel at those speeds. ... show more

    • Good kit, great company
Color: 27.5inch Rear
Review Image by Jesse Jesse
The media could not be loaded. It's a good kit by a great company. I had some issues with a couple of the parts in my kit. However, the customer service was excellent and I got speedy replacements. I installed the kit to a Giant Talon XL Aluminum mountain bike with disk brakes. I added a few things such as 12V converter for automotive grade LED lights, a rack to mount my battery, a full frame bag, and different sprockets. I put a 52 tooth front, and 34-11 tooth rear freewheel on it. This allows low gear to pedal uphill with no electric assist, and also pedal along at a comfortable cadence up to 45 MPH. Just keep in mind you need a compatible rear derailleur and a few extra links in your chain. I would recommend similar upgrades if doing long commutes and night riding. The power is great and on the higher settings will try to wheelie if you're not careful. I paired mine with a Unit Pack Power 72V 40Ah battery. That battery is very big and heavy, makes the bike awkward to maneuver when I'm not on top of it, and required a beefy custom mount. Not the battery I'd recommend for everyone, but I wanted lots of range and it was cheap. The range is 40 to 120 miles. I'm a tall and heavy rider, so me on the bike with battery, tools, lunch, work clothes and water comes out to 330 lbs. I have lots of steep hills and it's been windy lately. Even so, a charged battery gets up to 45 MPH on a slight incline very quickly with no pedaling. This style of riding averages 40 MPH will result in only about 1 mile per Ah. If I pedal along with it and average 35 MPH, it uses 11Ah to go 20 miles on those same hills, so the range is nearly doubled this way. Now a note here, I adjusted my amperage down from 40 to 20 Amps. There was only a slight uphill acceleration loss, but the efficiency went up, and the heat buildup went way down. I tried various set points, and I recommend 20-25 Amps. I think the motor and controller will last a lot longer this way(84V for charged 72V nominal battery X 40 Amps = 3360 Watts!, way over the 2000 Watt advertised rating), and I can confirm the range for 20 Amps is improved at the same speeds. Also note, that if you intend to use this kit over 25 MPH, I strongly suggest you have disk brakes and wear protective gear. I also recommend getting your wheels trued up perfect. if they're wobbling and bouncing it's going to be really bad at high speed. I recommend this kit to anyone with a little mechanical knowledge and OK with putting in some work to get a great end result. As a motorcyclist who also cycles for exercise (since my knees aren't the best when I run a lot), this kit is a perfect in-between which lets me commute to work, get my exercise, and have fun all at the same time. ... show more

    • Really good product. GREAT service!
Color: 26inch Rear
Besides a little tweaking to an older frame, motor and components went on easy enough. Engine rated for 72v battery but I opted for the 52v Hailong. I know a lot of people will say go for the bigger battery but I promise 52 was enough. Plenty of power and speed. 32mph was my top before I ran out of road Customer service was great. When I first messaged the company about some questions with the settings, I expected at least a week before hearing back..try about an hour! With the time change I was pretty surprised. Super helpful. One note I would say, when you get the large rim, look for any sharp points inside where the tube will sit. Try filing them down. Also run a couple of strips of electrical tape to help out the liner. First day I rode my bike I got a flat. ... show more

    • Wheel is good, but the controller is junk.
Color: 20inch Rear
Ok got the wheel, controller, and all. The first problem is the controller, it cooked after 118 miles. It shorted after a few MOSFETs brunt. Tried to have them send me a new one and they started with the 50 million questions on how do I know if it is bad? Well let's see, it stopped working for one, two it blows the inline fuse from the battery to the controller, three I tested the controller and looked inside and there are bad Mosfets on the blue leg. They never really offer to replace it until I said I would leave a bad review. Will they never replace it and made sure to keep me jumping thru do this and do that one too many times. So I will just cut my losses and use some other controller. Never trust anything from China with a so-called warranty. If they say it will take 72v be very weary. ... show more

More power than I thought a 2000watt motor would have/ easy to install I would like it better if it had a higher top end (speed)
