    Resources for DIY Inrunner Winding?

    Can any of y'all offer links to detailed threads or resources on how to go about wiring ones' own inrunner? I've been searching here but haven't come across anything yet. Thanks in advance.

    DIY Bottom Bracket Torque Sensor?

    I'd like to fashion my own bottom bracket torque sensor. The bottom bracket tube is 46mm ID, though I can go bigger if necessary. The current spindle is 19mm, though I may switch to a 22mm. Ideas? Threads?

    VESC Field Weakening

    I've just switched from an ASI BAC800 to a VESC 6.6 on my ebike. So far the VESC is working well in FOC mode. Among other things, I've been able to greatly improve my acceleration. But I'd like to be able to field weaken as on my ASI. This is not a feature that is available in the VESC Tool. But...

    Settings to dial-in the Talon 120hv?

    I'm experimenting with the Talon 120 for my Neumotors 8025 16 pole outrunner. It already fires the engine up just fine, and I'm sure I'll get it dialed-in eventually. But if anyone has any advice or knows of any threads for fine-tuning, especially in regards to the throttle, I'd love to know...

    Cog manufacturer?

    I need a 14mm keyed bore 12 tooth cog for a bicycle chain (preferably a 3/32" bike chain, but I'll settle for 1/8"). As far as I can tell, it doesn't exist. At least, it's not available online. I also need some even more exotic cogs machined. But I can't seem to find anyone to make this stuff...

    BAC800 vs. Neumotors 8025

    I'm attempting to use a BAC800 to run a Neumotors 8025, 150kv engine with hall sensors. So far, I can get BacDoor to run the motor using 'motor discovery' in both unsensored and sensored mode with the following general motor settings: Current: 90 RPM: 7759 Voltage: 56 Power: 5000 Sensor type: 0...

    Front freewheel torque: spragg vs pawl

    Can a spragg clutch bearing like the csk35 take enough torque to work just as well or even better in a front freewheel design that is not driven by an engine, but rather just cranked by average human power? We know from the old Elation design that the csk35 is not enough to work in a front...

    What's so bad about low impedence?

    So I sent ASI an email about using their controllers with the Neumotors 80xx series engines, adapted with hall sensors. They responded that the motor is "one of those low inductance/impedence" motors, and indicated that it would be difficult, if not impossible, to make it work with their...

    CYC X1 'Gear' version

    I like the idea of the final reduction being like the (nylon?) 'gear' version of the CYC X1. Does anyone know how well it holds up? Does anyone have a lead on some aftermarket parts to make that happen for my own design?

    10:1 right angle gearbox?

    I need a 10:1 right-angle gearbox that can handle a max of 8nm input and 10,000rpms, but is less than 4 pounds. Any ideas? Everything I've found online so far is way too heavy.

    Beltbox?

    I've been trying to design a gearbox around the Neumotor 8057 to drive the chainwheel from an all internal assembly a'la BBSHD. Every otherwise workable design I finish has the same unnacceptable flaw: it weighs a ton. However, I've been following an older thread on here involving a single...

    Worm gear reducers/gearboxes?

    Any recommendations for worm gear reducers/gearboxes that can handle 4nm max input torque? The lighter the better, of course. My apologies if this has already been discussed. I've been unable to find much searching the forum so far. Thanks y'all!

    Most powerful hub motor below 5lbs

    I'm considering a few new builds. One of them is a 20" wheel hub motor build. The top speed should be somewhere between 28 and 32mph, with lots of torque. I'd be using an aftermarket controller, most likely one of the ASI BAC's. And I'd likely use a high-C 21700 battery pack capable of 45amps...

    Astro vs Revolt engines

    I've just completed a BBSHD build with a good number of engine, wiring, and controller mods. I like it. But I have three issues. First, I can't run full throttle as long as I'd like without generating an alarming amount of engine heat. Second, I'd like the engine to fit into the triangle rather...
