    Its Finished - It even works !

    I finally have finished with a conversion of an old (circa 2020 circa 2002) Titanium framed mountain bike. It has a 250W rear Bafang hub motor, with 7 speed freewheel and 3 speed front gears. The eBike controller and spare bits of cable are in a small two part bag by the top tube and steering...

    Is the displayed motor power output accurate ?

    Bafang rear hub motor, 36v 250w, LCD3 display, KT36ZWSRD controller. The display shows the motor power in watts. At assistance level 1 and travelling at around 12mph on good level ground, the motor power is showing as circa 84W. Now if that figure is accurate and with a 36V 10AH battery that...

    Whats the difference with these PAS ?

    The PAS on the left (KTD12L) is for the left side crank, and when connected to my KT-36ZWSRD-HY02L controller, and the disk is rotatated as for forward, the LED flashes and the motor drives the BAFANG motor rear wheel. However I want to fit the sensor on the right (FOREN15194 C 2103 DH-SENSOR)...

    Interchange ability of displays for KT controllers.

    I have my eBike working, throttle only at the moment, still need to sort the PAS out. The display is an LCD3, which does work OK. Can I replace it directly with the much smaller LCD4 ? Controller is KT-36ZWSRD-HY02L

    Recommendations for a top tube controller\wire bag

    i have been trying out the options for where to place the controller and spare wires for my Bafang rear hub 36v 250w conversion. There is no room beteween the seat tube and wheel for a box, nor for one of those frame triangle bags by the top tube seat tube corner. There is room for a bag\box...

    PAS sensor on Shimano ISIS Cranks.

    I had anticipated that fitting a PAS to my bikes Hollowtech cranks might not be straight forward. I have a PAS disc with a sufficently large hole in it to go over the crank axle. I have fitted the PAS sensor as shown in the picture. The magnet disk is too thick, I will need to remove the...

    Rivnuts to mount battery

    The frame triangle on my bike is quite small, see attached picture. The frame is titanium and some Googling suggests the tubes are 0.9mm thick. Whilst I intially thought a bottle type battery (36V 10Ah) would fit, a diagram I saw (see picture) suggests there might not be room in the frame to...

    It arrived

    My Bafang rear hub motor kit has arrived, its a freewheel hub, time to start work I guess. Rear droputs need widening a little bit, a not uncommon issue I believe. They are around 9.5mm and need to be 10mm for the bafang axle. Never filed titanium before.

    Front hub motor with suspension forks.

    Is it a good idea ? Would a set of typical mountain bike front suspension forks cope well with the torque from the motor, particullarly if the rider is on the 'heavy' side. Are there front suspension forks specifically designed for eBikes ?

    Awaiting approval before being displayed publicly ?

    I posted a message, about freewheels on a Bafang rear hub motor, last Sunday. I seem to have upset the system, I replied to a post from vfr400 and included a link to a previous discussion on the same topic on this forum. Ever since the thread cannot be publically seen and is marked with...

    Rear hub motor mountain bike conversion – freewheel question.

    I recently fitted a Swytch kit to my Brompton, its OK for short commuting type trips, but in the area where I live (Cardiff) the roads are so bad the ride is a bit harsh to be fun for long. The extra stiffness of the front wheel cannot help. I have an old style Mountain bike, its a 26” wheel...
