NBPOWER USA FreeShipping !High Power e Bike kit 52v 2000W Electric Bike Conversion kit with KT 40A Sine Wave Controller,KT LCD8H Color Display, 7 Speed flywheel

Kit works well and is extremely powerful, especially with a 80a continuous battery. When I combined this kit with a 72v 80a continuous 35ah battery, unloaded wheel spun to 120kmh (74.5mph) on level 5. The different levels spin to different speeds and are well space out depending on how fast your want to go. I'm 6'3" tall and 260lbs, bike weighs a total of 78lbs and if not careful with throttle, this kit will cause the bike to pop a big wheelie which is awesome if you are an experienced rider but scary if you are a novice rider. I highly recommend dual torque arms and good hydraulic brakes as this kit is capable of taking your bike to motorcycle speeds. This kit seems well made. The wheel with hub was double layered and thick spokes used for strength. It is heavy duty and strong. Wheel appears fairly true as well. Wheel truing will be necessary at some point depending on riding conditions later on with the power this motor churns out. Controller and wiring is color coded for easy installation. I opted to not install the PAS because I didn't want the bike to get a power surge while pedaling. Assembly is easy. Make sure you keep the wiring from the hub away from your disc rotor to avoid rubbing and ensure all connections are solid. Many connections are optional depending on what you want to run. The only connections absolutely necessary to run from the controller on your bike are 2 to the front for the display and throttle and 4 to the rear hub for your hall sensor and motor. Two hall sensors are included, only one needs to be connected. If not using e-brake shutoff, ensure you are capable of shutting off the battery another way via installing a switch, turning it off through controller, or unplugging your battery in case of a runaway motor (rare). All in all a very fun kit and well worth the price paid. The cost to charge the battery is minimal (12cents to fully charge) and the savings from not having to purchase as much gas will turn out to a big win. Anne is very helpful and fast to answer any questions you have. I recommend this kit to anyone who wants a powerful e-bike.

If you build it right it can go 35-40mph and when my controller died they sent me another as soon as possible. This is a great brand and a great wheel would definitely buy again.

Originally I ordered the wrong rim for my style bike (an old Mongoose XR 200 that apparently no one else has put a rear hub drive on). Anne recommended the correct kit for my bike and refunded me the difference on top of that. It's a 48V1500W rear hub drive and I love it. Almost as fast as my 52V2000W. About 34mph and I'm a big guy(240lbs)with a 52V20ah Battery. The best thing about this kit was the wiring comes out at an angle instead of through the center like other kits. No removing pins from the connector. What a joy. I'm recommending this kit to all my biking friends. Anne is a beautiful person. A slight language barrier in the beginning but, that was my fault lol. Thanx Anne.

Mine broke on my second ride. She sent me a new controller but it shorted out as well.

This kit is very impressive and fast I would highly recommend it . If you want speed this is it . With this kit depending on your weight it can reach pretty close to 40 mph .

My girlfriend and I both ordered nbpower ebike kits...I received my yesterday. I been working on a build I'm doing waiting for this kit...well I got to tell you this is a quality kit and Anne is the best...she knows what she's talking about too...I highly recommend get a kit through them...I'll be ordering again...

I do like it, although I have not used it much yet but it works great.

The kit comes very well packed in its box. The kit is very powerful and fast. Ann is very polite and on top of your questions.
