Pedego PAS Design

I see some threads that say people have tried to climb hills unsuccessfully in PAS1 with cadence sensor Pedego’s (like the Element) but they’ve been able to do it in PAS4+. This really doesn’t make sense based on how I’ve been told Pedego’s PAS works, unless your leveraging the momentum of the extra speed you can get in higher PAS settings to crest the hill.

Pedego tech support themselves have told me that any pedaling at all picked up by their cadence sensor bikes puts the motor in full assist mode, 100% all in, the only difference in the various PAS settings is the speed at which the pedal assist cuts off. So PAS1 may have an upper limit and cutoff at 10mph, PAS2 may have an upper limit and cutoff at 12mph, etc, but there is no additional torque provided in each respective PAS setting. It’s simply like flipping a switch, the motor is either on (100% torque) or its off.

This is exactly what riding an Element feels like to me. In PAS1 through PAS5, as soon as you start pedaling and the PAS kicks in it takes off like a bat out of h*** if you’re in a lower gear.

Does anyone have any info to the contrary? If so, that would mean I rode a defective Element and Pedego tech support gave me bad info. I’m actually researching options to gradually ramp the power delivery on the Element as it’s otherwise a great option despite the on-off crude power delivery.

I have an Element which I understand is the most recent version, purchased the end of August 2022. The battery is in the down tube and installs from underneath. When in PAS1 and climbing a hill, the bike has to be going much slower than the ~8mph for the controller to apply full power. Bumping up the PAS level or giving it a bit of throttle ramps up the power more at the higher speed without the large slow down first. I haven't tried it yet, but I think I could ride up a hill in PAS1, but it might be at less than 1mph to do it only with the motor. I'd try it now, but I have to wait for my broken hand to heal.

Throttle response on the Element is very smooth. I wish my Avenue's throttle response was as good.

Tough to make sense of this. The Avenue has the same motor and (as far as I can tell) the same PAS & throttle system as the Element. Both have a 500W, 45NM motor, and a cadence sensing PAS.

Unless the Element has been updated and the website doesn’t reflect the updates yet?

When I picked up my Avenue, I told the dealer that my Wife's Avenue did not have as good of a throttle response and the PAS would not back off until well over the speed setting for that mode. When applying the throttle, rather than slowly ramping up, the minimum speed was quite fast, unlike my Element. Also, when riding in, say, PAS5, and then reducing it, all while pedaling, the assist did not reduce until pedaling stopped briefly. The Element has none of these issues. My Avenue behaves the same as My Wife's Avenue, so this appears to be an Avenue issue.

While the motor in both bikes may have the same specs, they do look different. The difference in behavior is most likely only a controller programming. As for climbing hills, I suspect that the programming is set to ramp up power based on speed below the set point and that the max speed drop is a fixed number, possibly something like 10km/h or about 6mph. This could explain why PAS1 isn't very good for hill climbing.
