    motor to make "digital drive" feasible?

    Yup, the refusal is just about balancing. At the slightest wobble she jumps off. And we're on grass. I did have a little breakthrough. I was riding the e-balance bike around while she was on the trampoline with friends. She jumped on and we rode together for a bit, even controlling the...

    motor to make "digital drive" feasible?

    I tried ordering ordering these "adult stabilizers" but it's apparently a scam site. Just got my PayPal refund. https://agouveia.com/product/bike-usa-adult-stabilizer-wheel-kit/

    motor to make "digital drive" feasible?

    I'm not ready to concede. She really enjoys cycling. She asked for her fat tire bike to become a trike so I did it. The rear is so wide that she has to leave it in high gear. She still rides it like a beast. I'm tempted to electrify one of the trikes for her but I want her to be comfortable...

    VESC: Can I make PAS work better than ADC with only torque?

    BTW, if you're going to use the Flipsky 75100 a lot, you need to be aware that there are fakes out there. I've gotten two through Amazon that had large bolts glued to the interior instead of PCBs. At least apply power and see if the LED lights before you shelve one.

    motor to make "digital drive" feasible?

    I made a tiny bike for my daughter who refuses to learn to ride. (Don't get me started.) She has amazingly strong legs, as demonstrated on her fat-tire trike, but I pulled the pedals off of this bike. My goal was to make an electric version of her Strider, which is way too small now. I want...

    VESC: Can I make PAS work better than ADC with only torque?

    Wait...other controllers don't have "current based throttles"? Hmmm...I took out my Lectra XP yesterday to look for a dog in the woods. It's the stock controller and I've disabled the damn PAS so it's throttle-only. It still seems unresponsive. What is the control method generally used for...

    VESC: Can I make PAS work better than ADC with only torque?

    I have a bunch of Trampa MkVs and I appreciate their quality. The STR-500 looks great for some projects, but not for little ones. I ordered a couple of Go-FOC M100s last month. I'll tear one down and see if the PCB is usable in a battery base. Nucular looks like good hardware but doesn't...

    VESC: Can I make PAS work better than ADC with only torque?

    I have been flailing, buying lots of controllers in an attempt to find a better solution than the Flipsky 75100. But I keep coming back to it. I feel like the obvious answer is to build my own controller but I haven't been able to get over the thought that there isn't anything better out there...

    VESC: Can I make PAS work better than ADC with only torque?

    There's no throttle. There's only a switch on the battery. It's as simple as I could make it. (I think about waking my new T17 builds with backward pedaling.)

    VESC: Can I make PAS work better than ADC with only torque?

    The pedal torque sensor is a 100mm T9. I didn't modify the 75100 except to solder the motor wires straight from the Higo connector (and the end caps).

    Torque sensor options in 2022?

    The Phoebe Liu Shop at aliexpress is where I've been getting my eRiders. My T17s just hit US Customs. I'm hopeful. I'm using my own controllers, so that's not an issue. I appreciate Justin but I want more control.

    Is there a reliable torque sensor?

    Oh! That all sounds great! Unfortunately, I see only 68, 73, 83mm versions. I still want one. Thank you for the references. I'm starting to feel like there might be something good out there.

    Is there a reliable torque sensor?

    I wonder how these differ from eRider. I have a 68mm Bafang around here somewhere. I'll find something to put it in to test. I contacted Autorq to buy samples. They certainly make big claims about reliability. Thanks!

    Is there a reliable torque sensor?

    I want to know if the rider is pedaling, even if it's so light that the torque level is in the noise. If I have the chain whizzing by my torque sensor, a separate cadence sensor is extraneous. Simple torque sensing gets a bit sketchy when standing on a bumpy downhill.

    Is there a reliable torque sensor?

    Thank you. I had found the Annoy Bike unit (while looking for a Beam TS) and it's what got me thinking about making my own. It's a little pricey for what it appears to be. (No chain speed sensor?) My eRiders have been failing into a 2.5V output with little to no variation due to torque...

    Is there a reliable torque sensor?

    I've been using T9 BBs with some success and lots of failures. I've got a stack of dead ones. I have a couple T17 BBs "out for delivery" right now but I'm wondering if I should rethink my approach. The more I read about torque sensors, the more I notice comments about how bad the designs are...

    KT-22A controllers dead?

    Also...is there an easily accessed tach/speed signal? I want to provide some speed control. I suppose I can grab it from the display lines. CAN?

    KT-22A controllers dead?

    Got it. I swapped the 3-pin cables and twiddled the settings. When I power on, the throttle is immediately usable. I can work with this. I'd love to know how to run it without the display. Thanks, all!

    KT-22A controllers dead?

    TopBikeKit *did* respond. The message directed me to use the three-pin plug on the splitter, not the one directly from the controller. That did it. Makes sense; I just got sloppy with all of the fancy colored connectors. Now the battery displays as full and I even got a voltage reading. I...

    KT-22A controllers dead?

    Oh! That is a big help! (The old manual doesn't list those codes.) I would not have expected the throttle. I just plugged in the one that came in the kit. I've been making twist throttles, so I have stacks of them around. I'll start swapping... Thank you!

    KT-22A controllers dead?

    Nice! I bought it with the waterproof round plugs. I got a kit with throttle and PAS. I definitely want to run it without the display, though (and without throttle or PAS). Is there documentation available for the controller? I've only found pinouts for the controllers in the huge aluminum...

    KT-22A controllers dead?

    Hmmm...it's a newish (unused) motor (which works with Trampa, including Halls) and the rest of the kit is new. I will check for bent pins, though. Thank you.

    KT-22A controllers dead?

    I bought a couple of 48V KT-22A controllers along with an LCD4. I tried both controllers with the same result. I connected the LCD, PAS, motor, and brakes. I powered from a 48V battery that reads 51V. I power on and the display shows normal (but zero bars of battery) and then quickly...

    This describes the kit I have with the "differential." Here's someone building something similar.
