    Fat Bike Kit

    Fat Bike Kit

    Hi tezdread, on my Motorset you don´t need to make thread´s to the motor, I was considering this way how Doug made it but I come to the conclusion "to complicated". That´s the reason why I chose the way with welding, nobody need a expencive tool (thread-cutter) for only one time using. So I...

    Fat Bike Kit

    160front and 180rear? I assume that your measurement isn´t correct standard for fatbike is 150mm front and 190mm rear. Before the standard was 135mm front and 170mm rear. Bafang have two hub-motors for Fatbike one is for 170mm dropout and the other is for 190mm dropout´s 250watt -->500Watt you...

    Bionx-SL Change the electronic

    hi folks, some people in germany asked me whether it is possible to run a bionx-SL with a replacement controller like a cheap sensorless controller or even a sine-wave controller from china. Reason is the Bionx-SL is now mostly out of warranty and often brocken, specialy at the torque-sensor...

    Problems with Mac motor cutting out.

    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...

    Nihola cargo trike, Bafang or Sunstar?

    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...

    BBS01 with 30 teeth

    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

    BBS01 with 30 teeth

    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...

    BBS01 with 30 teeth

    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

    BBS01 with 30 teeth

    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...
