Re: Single-speed track stealth ultralight

Thanks Papa. So I got a good look at the halls today. Everything looks sound visually. I didn't see any loose, frayed, pinched or otherwise damaged wiring. I also didn't see anything weird with the hall sensors or their soldering to the sensor carrier board. Unfortunately, the Paserunner still can't...

Re: Single-speed track stealth ultralight

I found this super tiny Xiongda YTW-06 rear motor on Aliexpress. I've reached out to them to see if it's available to fit 120mm forks. HTB1s9OkoxrI8KJjy0Fpq6z5hVXaT.jpg It looks like it's got 17.5:1 ratio gearing, and it has a side-exit cable. https://xiongdamotor.en.alibaba.com/product/60734803687-...

Re: Single-speed track stealth ultralight

Yeah, I have a thumb throttle on my other bike and it's been nice as far as ergonomics. I felt it was a bit too bulky for what I'm trying to do with this build though. Amberwolf: That's a great idea! I remember those from my motorcyling days. It could be a good option as I could take it off when I'm...

Re: Single-speed track stealth ultralight

I never showed what I did for the throttle. I ended up using Grin's new slim half twist throttle. Its really nice as far as half twist throttles go. I'm not sure I'm super happy with it. It seems like I have to shift my grip too much and put extra strain on my wrist with a half twist throttle. I'm t...

Re: Single-speed track stealth ultralight

I'm going to be opening my motor over the weekend to inspect the halls and wiring to them inside the shell. If you've been following the discussion in papa's Q100H autopsy and modify thread , you'll see that it appears that I received the wrong motor. Between getting a shell with defective spoke hol...

Re: Cute Q100H Autopsy & Modify 2017

So, using the gear-tooth counts from the motors papa and I received, we have: (15t x 23t) : (36t x 78t) = 345 : 2808 = 8.14:1 (Which very closely lines up with the advertised ratio of 8.2:1 for the Q100) If we change the gearing to what has been shown for other Q100H motors, we get: (9t x 27t) : (39...

Re: Single-speed track stealth ultralight

Yeah, I 100% understand that the regen values in my case don't mean a thing since my motor is incapable of regen. I get it. I just wanted to put real values in there, because it felt right to me. That's all. I know it will have absolutely zero impact on the performance or behavior of the motor and c...

Re: Cute Q100H Autopsy & Modify 2017

The first motor I received was an AAD3620A and not an BBD3620A and I bet that's why my gearing is 8:1 and not 12:1. Basically I got the wrong motor. But we'd never know without the discovery we're doing now.

Re: Single-speed track stealth ultralight

I entered regen values for my own piece of mind, but I know they'll never apply in my case.

EDIT: the Phaserunner will set regen values regardless of if your motor can do regen or not, so I just entered the values for my battery even though I knew they wouldn't apply.

Re: Single-speed track stealth ultralight

Papa: you mentioned that you were interested in seeing my Phaserunner settings for the Q100H. This is what I've settled at for now. I might tweak things once I can get my hall sensors figured out.

Re: Single-speed track stealth ultralight

I don't have any sort of a speedo or dash on the bike but I'd guess it was 10-14 MPH. I also contributed significantly with pedaling (almost at max without standing on the pedals). If I had to guess at how long I was climbing I'd say it was a total of about 20 seconds? I also started the climb with ...

Re: Single-speed track stealth ultralight

I figured out what was weird about the throttle feel. It was the sensorless starting delay. When you twist the throttle, there is a delay before the motor starts. I was misinterpreting it as an odd throttle ramp, but it was just the delay in when the power was engaged. Luckily that should go away as...

Re: Cute Q100H Autopsy & Modify 2017

Yeah, that's the Q100 not the Q100H. Which is what I was getting at before where the rear-drive Q100H is only 201 or 260 RPM, and the rear-drive Q100 is only 201 or 328 RPM. I don't know why the front-drive Q100H would be available in 328 RPM.

Re: Single-speed track stealth ultralight

I saw the 6th white wire coming out of the motor, and assumed it was the speed sensor. The hall connector on the Phaserunner only has 5 pins. There's nowhere to connect the 6th white wire, so I just left it trimmed-back and disconnected since I wasn't worried about knowing how fast I was going. Wher...

Re: Cute Q100H Autopsy & Modify 2017

WTF?! (insert pulling hair out emoji here) Why would they have a 328 rpm front Q100H and not offer that in the rear?! The only difference is in the axles. Argh! This is infuriating! The difference must be in the motor windings, and I am not going to strip down my motor to check it right now. I still...

I'm also seriously pondering the phaserunner, so will be interested in your numbers. Thank you! As a person who writes code (mostly backend stuff with no UI) the interface on both the Mac and PC version of the Phaserunner suite has me very disappointed. On both OSes (with autotune) there were place...

Re: Single-speed track stealth ultralight

I think I may buy a 90º Rosenberger cable and try to strip most of the super thick rubber sheath off of it to make a more flexible cable into my pack. I'm not happy at all with the current cable. I feel like I'm pirating cable while riding my ebike. This cable is as thick and stiff as a cable TV coax.

Re: Single-speed track stealth ultralight

So I've been messing with the settings in the Phaserunner Suite app and the motor seems to spin very nicely with out any load with these settings. My concern is why the phase amps can't be set lower than 35. I want to test the bike at 17 amps to the motor, then adjust as I get some miles under it. I...

Re: Single-speed track stealth ultralight

I certainly understand your frustration IDing specific differences between various generations of Cute motors. But it's vitally important that we avoid replicating assumptions. Among the many internal images I've seen, I have noted many obvious changes between the 1st gen Q100 and the later Q100H. ...

I apologize for the language. :oops: motomech has a good point, bunny-hopping on an ebike may not be realistic or good for the drive-train.
