    Hi David, Sorry for the slow reply. I get saturated with social media occasionally and have to step away for a few. It was nothing about your post. The small block drive with all of the mounts, ISIS BB, cranks, complete chainwheel with 219 primary is $650. I'm sorry that I can't really tell you...

    The BEST and FIRST Qulbix Raptor mid-drive build!

    Hi John, I'm not entirely sure what your goals are for your cargo bike build. Forgive me for not taking the time to read the thread. My experience with the sine wave and FOC controllers has been a hugely improved throttle curve, great maximum power and screaming high end performance thanks to...

    Eleek frames, made in Ukraine

    I made a donation here: https://hopeforukraine.net/ Hopefully my friends at ELEEK are following this thread now. They may have a better option. Thanks for caring. Ukraine needs the support of the free world to survive.

    Eleek frames, made in Ukraine

    Hopefully still will be. Europe is tragically accustomed to rebuilding after war. ELEEK makes two different hub versions of the Lite, one small motor and one medium. I would import those as complete bikes. I’ll order bare frames for my mid drive builds. You can also order direct from ELEEK.

    Eleek frames, made in Ukraine

    Most ebikers know ELEEK better as Vector, the Germany-based company that rebrands and marks up their frames. The difference between the two is the logo and a hefty price difference. I ordered one of their Lite frames direct. It took them a month to produce the frame and then shipping was two...

    A regular customer of mine found a LMX frame with a dead battery. Since LMX pilfered my old square wave motor years ago, my new IPM motors that are compatible with new high tech controllers like ASI will drop right in to the LMX frame. To their credit LMX did a good job designing their...

    Hi David, I’ve been working with the High Voltage Group www.highvoltagekits to provide plug and play high performance systems. They include controllers tuned for my motors, wiring looms, throttles, regen throttles, and displays. I don’t know about brake power cutoff switches. HV group also...

    Two things are required to learn: interest and humility. When you’re learning you feel stupid a lot. I bought books back in the Analog Age to learn how to wire cars, motorcycles and houses. I’ve relied on the internet to learn about EVs. Endless Sphere has been a huge help. What I didn’t learn...

    I also have huge respect for the guys who can scratch build a motor. After assembling hundreds of them over the last ten years I could scratch build a motor, but I don’t. I buy the main components and make only the specific parts I need for my application. My training was as a commercial artist...

    Tesla uses a Halbach array in the Model 3. Go to 10:40 in this video. https://youtu.be/aVnRQRdePp4

    Spinning magnets- I’ve never heard of any. Vad at PowerVelocity was talking up the virtues of the Halbach array so I did some reading and watched a few videos. Sounds pretty amazing and not all that difficult to manufacture. I found a couple of Chinese companies that will custom build these...

    LightningRods mid drive kit

    My initial motivation for making the move to sine wave was looking for smoother, flatter throttle response. Back in my square wave days I received constant customer complaints about the dead spot followed by huge kick on start up. The sine wave controllers are extremely smooth and linear. I can...

    LightningRods mid drive kit

    From the reading I’ve done it was suggested that surface mount magnets might provide a bit more startup torque due to a larger permanent magnet diameter in a given rotor. Square wave controllers are also known for a big startup kick and then declining torque as rpm increases. What you would...

    LightningRods mid drive kit

    Yes every motor I sell now runs great with FOC controllers. Top end power is way up and rpm increases are amazing- 100% rpm increase at 50% field weakening. The old stuttering and surging issues with FOC went away completely with the new motors.

    🤣 As I understand it that is a feature of the controller. People smarter than I in this area are discussing synchronous-reluctance controllers. Another great evolution of IPM, this in the rotor, is the Halbach array. There are companies that will make those rotors for you.

    Those crappy Honda clones are what sank the company. I don’t know why they were so slow to go electric.

    Pushing the boundary between “bicycle” and “motorcycle”. It seems to me that bicycles are too flimsy and slow and motorcycles are too fat and heavy. Why not have 20 HP in 120 lbs? (60 kg for you metric folks). This bike will have footpegs and be registered as a moped. Which is still a stretch...

    It works exactly as described. My old surface mount motors would have a big kick at startup and then fall flat. These IPMs keep revving and actually get a ‘VTEC’ kick on the high end. 20S rpm increases from 5000 rpm to 10,000. This is what a SurRon surface mount rotor does at high rpm.

    Yes I can do 14mm. I’m set up to do 4mm keyways. If you need something else I can do it for the additional price of the different end mill.

    Hi Brian, I sell 15mm bore sprockets but those are generally for jackshafts. Since I build every motor myself I can make a custom motor shaft for you. How long do you need the exposure to be?

    You’ve done a good job with your Cyclone. Running small chainrings does a lot to correct the inherent problems with the drive. You are going to have a LOT more power with the Big Block.

    I did find that some of the rotors I had in stock would conflict in the recessed splines of three of the bolts. The rounded tab around the rotor bolt would need to be ground back.

    NOW I get what you're doing! Brilliant! Upside down and backwards. No wonder I was lost! LOL Very clever! This will allow regen RHD solid mounted to the flopped rotor mount. As long as there are no issues running the brake rotor on the free hub this looks like a genius idea. :thumb:
