    Hub motor with internal gears?

    - Requires a whole new wheel. - Only external gear (bike is for my sister, so low maintenance is preferred = internal gears) - There's no derailleur hanger on the frame. - I already own 2 tsdz2 systems. Huge advantage running same system and batteries on all my bikes.

    Mid drive kit on Babboe City cargo bike?

    Yo! Im about to do the same modification for a tsdz2 on a babboe curve. But im curios if grinding 2 inches of that support center spline makes the frame weak?

    Hub motor with internal gears?

    Thanks for all the answers. I think i have to make a mid motor work. Especially as i have tsdz2 on 2 other bikes and i would like that theyre all the same. Upon inspecting the babboe curve, i think it may be possible with som modifying, Under the frame tube, theres a flat piece of 3mm metal...

    Adding electric assist to Babboe Curve cargo bike

    Did you go forward with this? I have the same bike and want to put a tsdz2 og bbshd on it. Looks like it should fit if the "flat" support piece under the frame is cut a few inches shorter.

    Hub motor with internal gears?

    I'm looking to convert a cargo bike (Babboe Curve). I already own a few bikes with tsdz2 mid-motors and would like to do the same to the curve. But due to the design around the bottom bracket, this wont be possible. The bike comes with a Shimano 7 speed rear hub, and therefore no eyelet for a...

    Is my BMS defective?

    I have a Hailong style battery, which wouldnt charge. After initial testing i replaced the BMS, which appeared to fix the problem. But at first test ride, battery would cut whenever i used PAS. It could power the display only just fine. I then measured and found all groups to be at 3,5 and one...

    Is my BMS defective?

    I have a hailong style battery with a hp16sa BMS. Few weeks ago it shut down and would not power my TSDZ2. I finally sat down and opened it up. Voltage on battery output is 45v which seems okay but i assume its below the TSDZ2 cut-off. But the problem is battery wont charge. I have measured the...

    TSDZ2 with VLCD5 shutting off

    Cables appear fine. I unplugged all cables and reconnected carefully. Some further testing revealed that the problem is somehow related to high amps. When i ride with little to no assistance i can go for more than ten minutes. If i go to "turbo" drawing max assistance, it shuts off after 1-2...

And then afterwards i cant turn it off. If i wait a few minutes, i can turn it back on but then only ride...

    Where do you find these overdrive versions? And how are they modded? Is it just software or?

    TSDZ2 higher RPM 36V motor with 48V controller

    Ive decided to go for a TSDZ2 but being a fit cyclist, i think the 90rpm limit might be annoying. Is there anyway to overcome the limit with one of the firmware hacks? If not, i have read about the 36v with 48v controller. But have a few quiestions. Is it as simple as buying a 36V 350W kit and...

    TSDZ2 versions and throttle

    Im buying a TSDZ2 motor for a bike projekt. The seller has a version both with or without throttle and e-brakes. I have no use of the e-brakes but i think i want to try the throttle for fun. So is there any difference in the motors/controller/lcd between throttle/non-throttle version? And can i...
