hi justin, it would be better but brings the price 2usd higher and the china factory only focus on the price never on quality I had this discussion for many years and tried to explain they should make the price higher for a better quality......

I would change the motor-cable if you have some welding eperience you can handle it. I always use extension cord, cut the side with no need away and fix the cable to the motor. It´s no so difficult but need time and patience ;) I didnt wrote a manual for the mac-motor how to do, I only wrote...

the chainline issue with bbs01 was a problem on my bike too so I bought this 42th chainring and it makes a much better chainline as the original Bafang now I can use all gears and no problems anymore, it is good but not cheap...

I´m with d8veh and flecc that the sunstar has to low power. If I´d build that bike for my wife I would go for a Heinzmann, convert the drop-out for cassette Motor and ready is a powerfull cargobike with 250Watt. The Bafang 250Watt is in my eyes also to weak. with 500Watt bafang it´ll work but...

I´m not sure that I understood what you mean but the 30t sprocket I mentioned is a sprocket from the shimano ultegra front chaindrive so it should work. the chainline is a different issue but even there I guess it´ll work because it´s a long way to the rear dropout

I took a look on the original 46t Bafang sprocket and it is five arm, so it would not be necassary to buy the adapter you can cut the original sprocket and drill five whole´s into the rest and then you can fix the shimano 30t five arm sprocket to the original rest. I think this is good, cheap...

Hi flecc, sorry for my poor english and yes mfj197 is right, thats what I meant Another idea I describe with a photo, how about that solution by using one part of the bbs adapter to fix a 30tooth sprocket in the front? then it would be exactly the requested sproket

I don´t know the sturmey so well but with a adapter you can fit 32teeth to the bbs-motor with 104mm. Is it not good enough for your hub-gear? from my feeling it should work the cheapest adapter I found in australia: http://ballaratebikes.com/collections/all need some fine finish because it is...

Hi Andrew, I like that motor much more as the bafang but honestly, there is no longtime use experience because the Motor just a few weeks in the market regards frank

About overheating most overheating is at the Hub motors. Problem on Hub motor is for two reason: low speed and high current for example on a hill. The rpm is to low for efficient motor work and this means only a few watt is use by the motor to forward-power the bigger part of the battery...

hi trex, I just check SFM sprocket ratio´s and come to the conclusion, yeab roundabout 4800rpm motor spinning if on the crank is 100rpm speed. It´s a inner runner with iron-core. I like that motor because it support with higher torque as the bbs01 and the complete motor looks better designed...

I used a 17amps controller setup and my wattmeter shows 750watt max The wire on the 250watt motor is only 1,5 so it is not able to take more for long time btw, full battery 42V but I guess you´ve pictured it at 750Watt ;-)

Hi folk´s, I received from my Chinese "boss" a Bafang fatbike-motor to check it out http://www.szbaf.com/en/components/component/motor/rm-g06350d.html bad point´s The brochure says it works for dropout 170mm - 190mm but forget it. The Motor is designed for 170mm dropout and that´s it. The...

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...

I just get the technical drawing for the Bafang SWX02-C maybe somebody have interest in it regards frank

yo that´s not normal but to identfy where´s the problem on a video is a bit difficult. do you have a resist when the noise is coming or when you spin the crank? Can you feel where it is come from? I mean from the axle or from sprocket-set The big sprocket turns the small motorsprocket and this...

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...

ups.... I was to fast or to stupid for a correct reply, maybe I should change my signature ;-) there is my text: that´s true and I have a real problem to understand why the throttle is so popular in britain. Many years ago when I was searching product´s to open a my first conversion-kit shop...
