Torque sensor performance

[Explorer-1]

@CityExplorer You have captured my thoughts perfectly....

Thanks for your thoughts I think you may have described well one of the differences between how one might approache cadence vs. a torque sensor bike. I can say that to me I choose a gear on my cadence based bike like I do on my manual bike, and that is based on how fast i want to go on average on a flat surface, or how hard I want to pedal when going up an incline and then choose the assist level to make that match my cadence and my desired speed. At least mostly like that. I would expect that the nature of a torque sensor would allow me to do the same, but it appears not. Like you said it's almost like the torque sensor is actively working to remove the advantages of an electric bike once you've started and traveling at speed.

Have you used the 'cruise-control' on your Jucied bike yet?

I have not used the cruise control. Most of my trips are 1-2 miles on city streets. Heck I rarely use the throttle. I just like riding like I would a regular bike, but it is so nice to be able to get from point A to point B expeditiously and with minimal effort. Cheers. Stay safe and germ-free.

I use the cruise control from time to time. Occasionally it's nice to just roll along, looking at the passing scenery, without dealing with gears or PAS levels.

I think a lot of casual users won't notice a small lag. I recall my CCS having a small lag, under a second, maybe 0.25-0.5. the lag also seemed greater with less battery.

I have tried cruise control on my RC from time to time but maybe because of the hills where I live it does not work so well. It wants to surge as though it is searching.
I haven't tried it while in the cadence mode though. Could that make a differance?

The cruise control is essentially no different than your throttle, as far as the controller and motor are concerned. A throttle that you don't have to keep your thumb on. Being in cadence mode wouldn't change it. It doesn't change how the thumb throttle works either.

Too bad, my cruise is all over the place also.

I'm curious. Is it all over the place if you're traveling on a flat, straight stretch? Mine varies with the load -- wind resistance, up and down hills, etc. That's because all it does is maintain a steady current, not a steady speed like a car's cruise control.

If yours is surging or sagging regardless of conditions, something is off in your controller and you probably want to start a ticket with Juiced while you're still in warranty.

I am having an issue with my ccs2 - not sure if it's the torque sensor or the brake sensor, or something else but if anyone has any ideas I'd love to hear.

The bike seems to "forget" it's an ebike for a bit. It will take anywhere from 2-10 seconds for the motor to turn on. I notice this happens when the brakes are applied, so my hunch is the brake sensor is mis-calibrated.

But lately, the bike won't seem to go into e-bike mode at all. It's just a very heavy bike now. The throttle works but not right away, and as soon as I let off, it dies. It's all on or nothing.

Any suggestions would be appreciated. Sorry if this is the wrong thread.

Update: turning off the torque sensor does not seem to change anything. I can get one or two "uses" out of the motor before it is completely unresponsive. The power does remain on, but the motor only outputs 4W.

Update again (how embarrassing). Troubleshooting proved it is the front break sensor. When I disconnect it, the bike works flawlessly. So my final question would be - how do I calibrate the front break sensor so it gets "unstuck" after use?

Interesting. I just received my RC2 over the weekend and I’ve notice basically the same symptom. Just less severe. Delayed engagement. Curious about brake sensor adjustment (if the is any) too.

It is up and down on flats. It seems like mine is trying to maintain a speed,so watts are all over the place.

Ya Bruce, on a level stretch with no wind it will vary by 150 to 200 watts. Now my throttle is exhibiting the same behavior. (Used to be very steady.)

Sounds like a controller issue.

Yikes! I did see a video on a controller change-out and it seemed kid of daunting...

I’ve been playing with the cruise control-works MUCH better at higher speeds.

I’ve used their torque sensors. I really like the torque sensors from Transducer Techniques. Their range for rotating dual shaft is 10 in-lb to 30,000
