Update for clarification:I purchased the offroad option and it works without further ado. There's a big R (Race) on the home screen.
I have the 250 watt version.

I'm actually about to hop on the Photon train, dude. I can't take this shit anymore. Spreadsheets, unlock codes, very weird business decisions, etc.
I know, right? Like usual, I'm just left with more questions.So what the heck does that cell voltage selector do anyway if it doesn't adjust the meter... hmmm

Sad to that the noise is bad And the other issuses as well.
It would nice if you could post a little riding video of it, as it is very few of them.
And they seems to have very different sound the few of them i have seen.
The last one on the owners group on facebook didnt sound too bad.
So we can hope it quiets down with the time.
I'm still waiting on mine a 1000w high torque.
I am putting it on a Mondraker Foxy. I hope it turns out fine.
Once you have pulled the chain tight, that's it... how can the sensor receive more data beyond that. I'm not saying that there is no modulation, but it is very, very subtle.
Yes, my experience, and I just did a couple laps to make sure I'm not crazy, is that it is kind of an on/off feel while you ride. Yes, it feels like cadence PAS without the smoothness. For another example, I have trouble lightly pedaling through a shift... almost feel like I need a shift sensor, whereas on my wife's torque sensing bike I've never felt the need for a shift sensor. I've been through the calibration twice.So it has more of an an on-off switch type feel.. engaging per pedal stroke, then disengaging..
That's really unfortunate if so, basically it's a PAS, without the averaging/smoothing that makes a PAS roughly tolerable.
I wonder if this wouldn't be as bad on my 42T with a 48v battery.
You have to do this operation to get the rider cadence:
450 * pinion size / chainring size
For example with a motor pinion of 10T and chainring 36T you get:
450 * 10 / 36 = 125rpm
Keep in mind, the chainring is invisible to the motor in this config. So 27.3mph is the max this motor can do with any chainring. Gearing above that doesn't make any sense.Good thing you found a way to game the system, lol.
That's an impressive speed for a 36T chainring actually, i think this indicates the high cadence..
Are you sure you don't want to try a mid mount with a bigger chainring? i have a mid mount if you want it.
nervagon, you are just too much of a powerhouse and pullIng the torque sensor to full deflection with ease!
In reality, results on torque sensing will vary by install as it looks like the standard and in-frame style torque arm are slightly different length and motor orientation/spacing probably affect sensitivity.
Is a stiffer spring on the torque arm a possibility?
Haven't weighed the bike. I'll just say that without the 21Ah battery it still feels like a bicycle. Keep in mind, this is a heavy duty Police service bike to begin with.It's been fun following your build. Thanks for the detailed documentation. Do you know the weight of the Bikee kit that's added to the bike? I just installed a Tongsheng TSDZ2 kit and it adds around 11 lbs to the bike (currently @ 42 lbs)
Got some math back from bikee ppl.
450v turns out to be the unloaded speed on 48v. So we have a 9.375kv motor
So what is the loaded speed? let's take an educated guess with a motor of similar efficiency, shengyi sx2 standard winding ( peaking at 88.2% eff )
The difference between loaded and no-load speed is 12.5%
87.4% of 450RPM is 393.75
At 48v:
36T chainring: 109 RPM <-- approximately the max for a short mount
42T chainring: 93.75 RPM <-- approximately the max for a mid mount
46T chainring: 85.0 RPM <-- requires the hybrid or long mount to fit a chainring this large
At 52v: ( add 8.3% speed because this is a 8.3% difference in voltage )
36T chainring: 118 RPM
42T chainring: 101.5 RPM
46T chainring: 92 RPM
I would bet we're +/- 5 RPM from reality with these calculations.
..yeah, the dual chainring system would be better because you could adjust chainring sizes and adjust the cadence to your preference. I doubt most people would prefer a cadence over 90RPM.
