Question: can someone pedal while using the throttle. I have only done one or the other but I saw someone doing both yesterday.

I'll do it because my legs get bored.

I use "clown pedalling" to make it look like I'm not using my throttle... However, I blew out the mosfets in my first controller doing that, apparently the KT controller decided to use both and seems to have doubled the voltage through them. I have disconnected the pedal sensor now, to keep that from happening again. 😮‍💨 On the plus side, the pedal sensor still worked, but only pushed the bike up to 15 mph down from the 28 it would normally do. So I'm on a new controller now.

If you had shunt modded the controller, it might have just overclocked your motor. I did that once, my controller would shut down when the torque load passed a certain point.

They call it "ghost pedaling".

Yup. I usually can get up to +6mph

This would likely only be possible with a torque sensor. Pedaling and throttling at the same time shouldn't make much difference with a standard cadence sensor.

Care to explain what the type of PAS sensor has to do with this?

Hint. It doesn’t.

Once the motor reaches its top speed, pedaling faster does nothing (e.g. ghost pedaling) with a cadence sensor.

With a torque sensor, you can add additional energy into the system by pedaling, even if the motor is at the max.

This isn’t a function of the sensor, it is a function of how the controller works with sensor data.

But also; if the motor is at its maximum rotational speed then the motor cannot assist you if you’re pedalling faster than that. Something something physics, back emf, motor theory, something something.

Or just think logically, and realise that if a motor is at its electrical speed limit then what kind of sensor is connected to its controller can’t change that the motor is at its electrical limits.

The sensor mode does matter on a Velotric Summit 1. In torque mode, applying the throttle will increase output. In cadence mode, applying the throttle while pedaling actually reduces motor output.

I think it is(?) bike is really slow. It goes 21mph full power without the limiter, so pedaling makes a difference

Yes, but it can be counter-productive.

In the case of the Velotric Summit 1, the firmware provides the most assistance in cadence mode PAS. And a few hundred watts less in response to the throttle.

But it's programmed such that throttle activation overrides PAS. So applying the throttle while pedaling in cadence mode actually reduces motor output.

Yes, there are a few ways you might want to use the throttle to change the motor behavior while pedaling. It won't hurt the bike or anything, it's not like pressing the gas and brake simultaneously in a car.

Usually the throttle will let you get max motor power instantly. So any time you want to briefly get more power without switching up from lower assist levels, or get a more predictable launch on a cadence sensor bike, the throttle can be useful.
