Thanks for the help. Perhaps a bit more information... The standard wind Bafang G020 that I am happy with is a 48w 500w geared hub motor. It is mated to a KT 22a controller and a 17.5ah battery. (original Bafang controller was 18a) Even though the motor was taken out of a 26" wheel, it works...

This is what I understand, and is the reason I want to do this. Since there is very little difference between a 22A and a 25A, I probably should just get which ever is least expensive.

I am happy with the G020 I have on trike No 1. It tops out around 20mph which is as fast as I go, and it climbs great. Since this is the case, I will just build another duplicate wheel for trike no 2. Going through all of these posts and the research I did only seems to validate that as the...

Neptronix, thank you for your help. From your last post and playing around with the simulator tool, I have drawn a few conclusions: 1) With the same motor, performance with a fast wind/20" wheel is more or less the same as a std wind/26" wheel. The major difference (at least for me) is the...

My 500w Bafang hub motor came with an 18 +/- 1A controller. I upgraded that to a 22 +/- 1A KT square wave controller. I am now looking at a KT sine wave controller rated at 24 +/- 1A. I assume this will be ok since my battery has a 30A BMS. I also have the option of sticking with a KT sine...

Thanks for the responses. I did play around with the simulator before posting this. I found that differences between the std and fast wind can be significant different depending on the motor. I will go back and play with it some more. neptronix, can you explain this statement to the...

It is my understanding that 26” wheels normally use a standard wind motor, but 20” wheels normally take a fast wind motor. I have a Bafang G020 geared hub motor with a standard wind that came off of a 26" wheel. I am using it on smaller 20” wheel, and it seems to work fine. With the smaller...

I know just enough about the winding of hub motors to be dangerous. It is my understanding that 26” wheels normally use a standard wind motor, but 20” wheels normally take a fast wind motor. The G020 motor seems to work fine with the smaller 20” wheel. With the smaller wheel, the top speed is...

Thanks for the comments, all very informative. Both of my controllers are square wave KT controllers. A sign wave KT controller is more difficult to find and quite a bit more expensive. Would a sign wave controller be that much quieter? Also would the square wave and sign wave controllers be...

I have two trikes, both with Bafang 500w geared hub motors. One has a model G060, and the other has a older CST motor that I purchased used. The 060 is very quiet, and I have no problems with it. The CST motor is noticeably louder. It makes an audible whine when running. This whine gets...

I guess there is no such thing as a decent quality moderately priced battery. I may have to rethink even doing this project.

I have pretty much settled on this battery from UPP's Amazon store: https://www.amazon.com/gp/product/B09MCW6WPJ/ref=ox_sc_act_title_1?smid=A1RAY93OUH65CI&th=1 A few of the reasons are: (1) It uses LG LG 21700 cells. (2) At 19.2Ah, it is slightly larger than my current 17.5Ah battery. (3)...

I found the UPP store on both eBay and Amazon. I also found other sellers offering UPP batteries, but I'm not sure I would trust them. I'd rather go right to the source. For $305 I can get a 17.5Ah built with Samsung 3500 cells, or $369 for a 20Ah built with LG 21700 cells. Either would have...

It does not have to be Amazon, it's just that I've had good luck with them in the past. I'm looking for a 48v battery. I did find UPP on Amazon. I was concentrating on the batteries they claimed have LG or Samsung cells. They are more expensive, but I do not want something unknown just to...

I am adding a rear hub motor and battery to another recumbent trike. The kit I used on the first trike came with a 17.2Ah shark battery. Having learned a lot from the first build, this time I am not using a kit but building it from scratch. This trike will be used for casual rides in a hilly...
