    bafang crank drive kits

    you´re right about the dominant possion in europe from Bafang. Even I´m not a fan of Bafang I must admit that they found a way to be popular in europe. I was one of the first seller in europe who has sold Bafang but Bafang was also the reason why I didn´t wanted to be a seller for e-bike motors...

Chain-gears has the same problem...

I would buy the red/yellow one the circlip-plier you better buy as a set but even a set is not expencive maybe 30euro and have sense if you...

    Repair BBS02 Bottom bracket

    Hi trex, I cant realy explain because after a lot of talks with Mr Wang, the Boss from Bafang, I gave up talking about quality and improvement. My solution is, try to collect information about the product and do the maintance by yourself. the chinese simply don´t care about if maybe 10-15% of...

    Repair BBS02 Bottom bracket

    the click might be the needlebearing inside the bottom-bracket. The Bafang is easy and cheap to repair even for people with low mechanical skill´s The value of warranty from bafang or other chinese companys is zero but it dosent matters. All Bafang BBS-part´s or bearing is easy to buy and easy...

    What watts?

    I think 350watt is enough for a ebike as the best mixture for weight,consumption and the feeling to ride a bicycle and not a Motorbike. But It´s just my personal opinion and other user´s maybe come to a different conclusion I´ve tested a lot of different motors/bikes from 150Watt up to...
