February 8, 201511 yr Hi folk´s, i felt a little bored and ordered in China the new small SWX02-C Motor from Bafang and from Xofo I ordered the XOFO-XFK motor Both Motor is 200rpm for 26inch and 250Watt. They look nearly similar from Outside but inside is different. I wrote two PDF-File´s for the description and make it now here in Forum public, everybody can download and see for himself Driving: the bafang runs a bit rougher as the xofo but the bafang has bit more power but just a bit (three people come´s back with the same impression) Both Motor have a bit more power as the predecessor models from this manufacturer´s Both motors is tested in the same bike with the same controller and even same tire to get a clear impression The Bafang SWX02 has a 25% higher price as the XOFO-XFKBafang SWX02 CST.pdfXofo Motor XFK.pdf Edited February 8, 201511 yr by mechaniker
February 12, 201511 yr Author I just get the technical drawing for the Bafang SWX02-C maybe somebody have interest in it regards frankswxo2 c.pdf
February 12, 201511 yr Author How does It compare with bafang cst 250w? Oh Bafang have some different 250Watt rear-cst´s If you give me your mailaddress I can send you the complete salesbrochure from Bafang. I made photo from each page and there you can see also the measurement of each motors A lot of different motor-drawings you can also find on my friend´s website in China: http://www.woaczh.com/show_list.php?id=3 regards frank
June 2, 20187 yr I just get the technical drawing for the Bafang SWX02-C maybe somebody have interest in it regards frank Hi. I have a Bafang SWX02 motor (full serial number is BFSWX02 48V (10) 700-C 1707185141-6). Does anybody know where to find the full technical specs including power output for this motor? I need to get it because but so far don't have anything much in the way of proper tech docs, and I need them in order to register the bike (in Europe, not UK). Any info appreciated.
July 10, 20187 yr I got the BFSWX02 36v250w and would like to know if it possible to put in some more Amps in it? It´s 8 right now but if I raise it to 10 its 300 Watts and 12 It´s 420 Watts, but could it handle that? I want it to go faster and bee stronger .

Show us a pic of your controller 8a might be it's rating but bet 15+/- 1a is it's max rating and will be outputting a possible 500w + already. 17 or 20a controller should pose little issue for a big Bafang.

Here is pictures of both controller and motor and cant find any data about them on the Internet! But as it street legal here in Sweden then i think the controller is set to 8 amp output! Another thing is that there are 5 cables from the Controller! Battery, 1 brake, Display, magnets,and motor. Edited July 10, 20187 yr by Killerbritt

July 10, 20187 yr The hub is legal as marked 250was as stated by EU legislation, there is no set legislation for controller amps so only can be set to 8a via lcd programming. Yours is 13a +/- 1a so it will give at least the 13a under certain conditions. Hub is marked 24 for 24" wheel. (12) is the hub winding speed which means AFAIK 250rpm no load speed with 210 load speed. Should be able to top out at 30/32kmh unrestricted in a 28" rim.
July 10, 20187 yr Szbaf/bafang/8fun are one, mostly OEM bike component suppliers in the west with only a few hubs made available to retail sellers , controllers are non retail and appear to be only OEM products. For upgrading controller you will most likely have to use Kunteng aka KT for controller and lcd as these are the most commonly used ones available . Ldsz/Lishui are another manufacturer but again mostly only supply to OEM market.

It´s a cargo bike with 3 wheels thats why it´s a 24. I did the opposite and went into the Display sub menu and program it for a 18 wheel and got 4-5 kmh in extra speed, but the bad thing is that the speedometer don't show the right speed. I have the C961 Display and thinking if I can use the BBS02 and BBSHD programing tool to change some settings in the controller! But i don't know if i burn the controller when i connect it! I also upgraded the battery to a LG lithium battery 36V17Ah with cellphone charging USB 3A Charger Bracket. So basically i´m looking for a way to get into the controller and change the settings .

July 10, 20187 yr I doubt that the controller is programmed for less then 13a, if the bike feels like it is wanting in power then is likely the extra weight and geometry is wrong. Most aluminium case programmable controllers have a white date cable/plug for programming, it is possible but I doubt bbs prog software is the same as hub controller software, maybe you will have to be the guinea pig to try . I doubt you will damage the controller , software most likely will not recognise the controller. Edited July 10, 20187 yr by Nealh
July 10, 20187 yr I doubt that the controller is programmed for less then 13a, if the bike feels like it is wanting in power then is likely the extra weight and geometry is wrong. Although both Bafang I doubt bbs prog software is the same as hub controller software, maybe you will have to be the guinea pig to try . I doubt you will damage the controller but software maybe will not recognise the controller. You a right and the best would to buy a new 36V350W motor! But then i need a new controller and LCD and that would be like 400-500 $.and all the work to install everything! The only thing i want is to get ride of the 25 km/h restriction so i can go 30-35 km/h instead .
July 10, 20187 yr The only way to get rid of the 25km/h setting is to get a complete KT 17a controller and lcd 3 kit, inc a pas, throttle,brakes,speed sensor etc,etc. Using PSWPower shop on Aliexpress cost is about $105 delivered. https://www.aliexpress.com/store/product/36V-48V-350W-Brushless-DC-Sine-Wave-Controller-LCD-or-LED-Throttle-Brake-Lever-PAS-Speed/1314442_32623312368.html?spm=2114.12010612.8148356.50.5e8711bazYMewE Your 250w hub will work nicely with 17a controller kit.
January 20, 20197 yr Hi everybody It's first time I find concrete information about BAFANG motors. My recumbent bike (26") is fit with a hub motor BFSWX02 36V26 1504073020-6, a 13Ah SAMSUNG BATTERY & a display C302-1503-C987 36V - V2.6C There is no apart controller, I only find an electronic cards inside the battery and it seems there are some electrical connections inside the supporting rail of the battery. The system is driven by a magnet sensors fixed on the crankset, really not accurate and sensitive. My question is about the potential of the motor: knowing the part number of the BAFANG, could everyone tell me the max speed of this hub motor ? In fact I would like to replace the magnet sensor by a torque sensor and ride easily up to 40-45km/h Best regards
January 20, 20197 yr Is there a number in brackets ( ) on your motor? This is the winding speed and tells you how fast the motor will spin. As you will have read, it is not really poss. to change 1 component on the bike as it will not work with the rest of the system. If you want a torque sensor you will have to fit a new controller and display. The board inside your battery rail is the controller.
January 20, 20197 yr Thanks for your quick response. I don't see any number in brackets as already on picture's net (it's strange !) The supporting rail is really thin (less than 15mm). Is there a possibility that the controller is located inside the motor? It's not a problem to change the controller, I'm sure it's necessary to manage the signal from the torque sensor in place of the magnet. best regardsBatterie SAMSUNG Li-Ion 36 V 13 Ah 468 WH Samsung, par exemple pour NCM Prague, leisger MD5 S...pdf
January 20, 20197 yr AFAIK, bafang do not make a motor with controller inside. Where do all the cables go to? If you have more than 1 cable to the battery holder, then your controller will be inside. Yes, if you buy torque sensor it will come with controller and display. There are not many TS kits available, here is one. https://bmsbattery.com/ebike-kit/689-b-b-torque-sensor-system-ebike-kit.html If you can wait, this one may be for sale soon from Woosh. https://www.pedelecs.co.uk/forum/threads/could-you-give-me-your-opinion-on-this-kit.33596/#post-479429
January 20, 20197 yr Thanks for infos, the torque sensor is in $, I guess it come from US. I never ear about this material. You are right, both the sensor and the display are connected to the battery holder. I read a lot of things about cycle analyst. the CA can manage BAFANG torque sensors. What do you think about this material ? Best regards
January 20, 20197 yr Oh Bafang have some different 250Watt rear-cst´s If you give me your mailaddress I can send you the complete salesbrochure from Bafang.

January 20, 20197 yr BMS Battery in the link are in China. The Cycle Analyst is a clever bit of kit and the latest version will run a TS, but you will need a controller that is wired to work with it, something like an Infineon or Phaserunner. EM3EV in China sell these parts. https://em3ev.com/shop/?prod_cat_=ebike-display
January 20, 20197 yr Yes they do several and I have to say I was/am completely baffled at the differences between all the choices as it's not clear on their website at all! The Bafang website is not a great place to try and choose a motor as they do not sell to the public. Look around different sellers to see what they offer and make your choice from them.

Tell us the number and we can ascertain the motor winding in RPM and the speed it may attain. The bikes controller will most likely be at the base of the battery rail, it should have three round wire cables that emerge at the bottom end of it.
January 20, 20197 yr The BMSB TS kit is 15a for 36 & 48v version. I did see a 18a TS kit on Aliexpress.
