Review: Best deal for your money - 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.
Review: Really good product. GREAT service! - 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.

## Questions & Answers

**Q: will a 52v 13ah battery work well with this kit?**
A: It should work, the only thing it will drain your battery faster and you'll have a bit less torque than you will with a 72v battery

**Q: Why is it advertised as a 2000w kit when 72vX45A=3240 watts?**
A: The 2000w is the continuous wattage the motor can handle without burning up, the 3240 is the peak wattage, this is the wattage the motor will use when you start moving or are going up a steep hill.

**Q: Will a 72V 17Ah battery work with 2000w kit? How far will it go?**

Your battery can work with this 2000W Ebike kit;the cycling distance is related to the speed and battery capacity;
