    Crystalyte UFO acting up at end of long rides

    Well, thanks! I never guessed I'd get feedback on those :) My aim was to capture the gaps under the magnets, and the white cardboard turned out a good choice for that. Instead of trying to get up close, I used the optical zoom from a foot or so distance and tried winging it to get a shot of the...

    Crystalyte UFO acting up at end of long rides

    Cleaning up the rope didn't solve the problem. I took the bike with me on holiday to the South, and riding in the baking sun discovered that high rpm is not a requirement, as the issue always occurred under load and while the hub motor is hot. So I was mostly reduced to enduro "strolling"...

    Crystalyte UFO acting up at end of long rides

    As fate would have it, shortly after posting this topic, a friend brought in his bike with the same hub motor as mine, for which I diagnosed and replaced a faulty HAL sensor. This helped me to compare his hub's innards with mine. (The only difference between his hub motor and mine is that mine's...

    Crystalyte UFO acting up at end of long rides

    Thanks all for the suggestions. Though there are XT150 connectors on two different places along the path between motor and controller, and I have found those to be treacherous at times (especially when shrink wraps covers their butts, hiding they've half slid out of their enclosure instead of...

    Crystalyte UFO acting up at end of long rides

    After several years of use under high load, my hub motor starts making an "angry duck" noise at high rpm and under load, after about 15 miles into my rides. When the noise comes up, the motor stops providing output. Luckily I can still coast at low rpm's. The next day everything's fine until I...

    0% to 100% proportional regen with separate throttle

    That looks quite interesting. A mechanical brake AND a thumb throttle for braking is indeed one option too much in emergency situations. The challenge would be to integrate this gracefully with a disk brake lever. It looks like Nixumen nailed it. There's also mention of a pressure sensor...

    0% to 100% proportional regen with separate throttle

    Yes, your chop job inspired me :lol:

    Phaserunner on 3KW motor

    It's the KLS7218S 24-72V. I need to take a little detour here, bear with me. No one likes to ride a bronco for a stroll in the park. I wanted a bike that could shred the asphalt when I wanted it, and coast along smoothly at low speeds when "going for a walk", without fearing the powerful...

    0% to 100% proportional regen with separate throttle

    OP waking up from the dead here (and being granted a break from his 3yo son's attention grabbing). My solution has been a Kelly controller, with left "push" throttle for regen, and a Domino full twist throttle on the right. The controller's regen is smooth and powerful, as advertised by the...

    Phaserunner on 3KW motor

    In the fine tradition of "better late than never", I'm following up on this question. I ended up installing a Kelly controller that does 80A continuous, and 200A peak. I also swapped out the battery for a more powerful unit: 15s6p (54V nominal, 20,5Ah), discharge rated at 60A. To my standards...

    Phaserunner on 3KW motor

    The docs on the Phaserunner state it's "ideally suited for running brushless motors for electric vehicles in the 500-2000 watt power range". On a system with a 48v 40A battery and a Crystalyte 4080 "ufo", would swapping out a Grinfineon 40A controller for a Phaserunner be a step-up in terms of...

    0% to 100% proportional regen with separate throttle

    Tested so far: proportional regen with - cycle analyst 3.14 - one throttle - pressure sensor on a Magura hydraulic brake - grinfineon controller (the 40 A one) - UFO crystalyte 3KW motor Regen worked well in this setup until the pressure switch started to turn on randomly, and now stays on...
