We had this weather today, I thought of having a swim but forgot my towel ;)

Oh man! What a drag. Long time since I saw that much snow :) time for a fatbike! :)

mmm, yes, maybe it's not worth worrying too much about this. It was just a little interesting :) Found this graph of a standard BLDC-motor. http://www.mellorelectrics.co.uk/BLDC-MOTOR-EN.html Maximum power is delivered way before the efficiency peak. Because of that I have actually two...

Got reply from Green Bike Kit. They just say it is different and not gonna work :) but when I asked about what is different I got this pic. Seems rotor is also different. Still I am not 100% sure about this but I felt that I can't really know until I've tried myself so I ordered the stuff :)...

...ok, yes, I am about pulling the trigger here. But I can't get wise about the rotor. Some stores list the BBS01/BBS02 rotor as same article no (68mm). While the BBSHD has both 68 and 72mm. Kind of strange. Need to investigate more. Meanwhile I made a Photoshop comparison of a BBS02 to my...

I was thinking about that. Is it really good for efficiency to pedal near motor max rpm? This max rpm that it has, is it the physical maximum rpm or is it some limited rpm? I mean, isn't this kind of motors most efficient in the 65-85% range of top rpm or something like that? In that case it...

Ok, then I understand. The standard ~50mm is not great either so I was worried there :) I just put an order for a new 11-46T cassette for mine :)

mkay... but if you change connector on the BBS you can use external controller also. If you want. But I like the programming capabilities of the stock controller so I don't wanna change :) Is that the dimension that is 50mm on above BBS drawings? strange if so

Now I have found drawings of the two. Have read that BBS02 is bigger, just didn't understand exactly what dimension is changed. Seems it is only the "axial" length of the motor. 6mm more protruding to the crank arm. No problem. Also, the rotor can be found in various spec so I guess a new rotor...

The stamp is on the BBS-chassi. Stator and controller are spares. So that would not be a problem. And I should use the same controller, probably with same programming also, so no tuning at all :) Mine is so used it would be pointless trying to sell :) changing stator is easy. I had it removed a...

Yes, I get what you mean. When I first got the bike this issue was a real disaster. The stock parameters was really bad. But now I have changed them. I have tried with both at 100% and it gets "almost ok". But still I always wish it would assist higher up. Found a great thread on Endless...

Hi all, I have long been disturbed about the BBS01 low speed. Only rated 78 rpm at 36V/250W version. Personally I like riding at about 80-100 rpm or something like that. So the BBS01 cuts out just when beginning to reach the sweet spot. How to fix this? I guess you can't change this through...

Also a cheap phone, Xiaomi budget phone. The trick is to have alot of luck :) (I shot several photos there, only a few got good exposed)

Another fantastic day! Next week will be sheitt so I took the oportunity today again.

Georgehenry! Your way to work is most inspiring. Fantastic! Don't complain myself...

My bike almost got stolen by this green guy when off for a **** today

This is it!

yes, and weren't they easy to maintain? :)

Lifting this question again. I have changed from Bosch CX to Bafang BBS01 because the Bosch Broke all the time, but now I have just serviced the BBS01 and it seems it was not good anyway. Don't like this built-in systems with 50 bearings and washers and so many things with difficult...

Got the shaft removed. Have inspected all bearings. Feels ok, needle bearings feel maybe not top notch but that can't be the problem. I thought it was the rotor inner bearing after seeing some videos but that one is ok. Very strange. Still think it was short-circuit of the hall sensors or...
