    GearSensor vs Pasion ShiftSensor

    Has anybody used the ShiftSensor? I am guessing it is a clone of the GearSensor? This seems to be half the price, and readily available in the UK...

    52v 14s4p Hailong Case

    Started with plans for a 13s4p battery build, but as I am going to have to glue the cells I may as well go to 14s4p. I have seen the following of the Luna pack, but have not seen the other side. Before I copy the layout, could I check that it is the best design. For 30amps max current (BBS...

    KWeld vs Arduino Spot Welder

    The KWeld is over €200 delivered in comparison to the €120 Arduino kit. Are there any advantage to the KWeld? Both look good for the money, but struggling to understand the price difference. https://malectrics.eu/product/diy-arduino-battery-spot-welder-prebuilt-kit-v3/...

    Motor Problem MSUX/Lyen...

    I have a problem I am finding extremely difficult to resolve. I had a Lyen 12fet + Crystalyte HT3525, with the correct Phase/Combo the motor would turn unloaded drawing circa 3amps. I had put 1000 miles on it, no problem. A year later, when unloaded, the motor sounds fine. Once on the ground...

    HT3525 Motor Noise - Electrical?

    Have a motor which sounds like the wrong phase connections have been used. On the bench, you can just hear it. (Video below) There is the 'usual' noise almost masking it, but you can just hear 'pings' every so often. The pings sound like electrical noise. When there is a load on the rear...

    Vectrix VX1 - New Toy!

    Hi all, first thread for me over here. I am usually on Endless Sphere building bikes, but have taken the step into motorcycles; the Vectrix being the start. I picked this up in Oxford, a couple of hours away from me in the UK. The owner said he left the bike for a while, plugged it in to...

    Which throttle? Replacing Magura..

    After using a cheap hall sensor throttle on a 24s build, I immediately upgraded to a Magura 5k pot throttle. I was surprised to see that a couple of respected forum members were then opting for a hall sensor throttle on a for sale thread...

    12g Spoke Washers

    Has anyone found a source for these? I have bought these from ebay, but they are too small. http://www.ebay.co.uk/itm/161188452608?var=460258069640&ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649 I presume M3 washers are going to be too thick...

    Pre charge resistor check

    There seems to be conflicting views on the the size of resistor to use, so just clarifying that a 150ohm 10w resistor should be fine. 24s lipo Lyen 18fet - Every capacitor on the board counted.

    Rebuilding 4080 - Help!

    Stripped the motor last night to check polarity of the hall sensors last night, but for the life of me I cannot get it back together. I have stripped it down to, brake side plate, freewheel side plate, stator and outer rotor. 1) I have the stator in the vice, I am doing the brake side...

    Checking polairty of hall sensors

    Is there a way of doing this without having to strip the motor down completely? I had first though of using the gear puller on the freewheel, to pull that side plate off but think that will cause too much stress on the freewheel threads. Any better ideas, able to check with a multimeter?

    HT3525 Hall Sensor Pinout

    Do Crystalyte motors from Europe have the same Hall Sensor pinout as the ones from the US? Didn't want to remove the heatshrink unless I had to.

    Replacement HS Shaft Concern

    Ordered some replacements earlier this month, but the channel for the phase wires seems to have been cut too far into the shaft. The issue, is that there isn't a flat for my dropout to sit on anymore. The channel is 10mm into the what. Other than having to add/weld torque arms (which I...

    HT 3525 Wiring Mod - Still Required?

    I have in my hands a new motor from Crystalyte Europe in front of me. On my last one, I did the wiring mod but I am hesitant to remove this one as it looks to be a newer version. Is anyone still having the old problem of cutting wires on their HT/HS motors still?

    12fet Lyen Controller - Fault Finding

    Looks like my controller has cause an issue with blew all the hall sensors in my old HT3525. After replacing the halls, I tried the old 12fet controller and it would not power up. (no output on the Lyen tester from the controller) I replaced the 12fet for a new 18fet I had laying around and it...
