From the article:

> It also features a throttle good for 20mph where regulations allow.

That must mean they have a class 2 option.

The way I read it is if you use throttle-only you can reach 20 mph, but then if adding pedal-power you reach 28 mph. The pedal is probably not generating sufficient force to add 8 mph, but it’s telling the control system to do that.

class 2 and class 3 are mutually exclusive. You cannot legally have an e-bike that supports throttle up to 20mph that can also continue to e-assist if you pedal up to 28mph. While it's technically possible in software to switch between these modes, consumers aren't supposed to be able to do this on their own.

You have an incorrect definition of Class 3.

Class 3 allows pedal assist up to 28 and throttle to 20

I did it on my e bike...all I did was lie to the computer about how big my wheels were, which was a directly accessible in the settings menu

You can usually limit the bike to go less than 20mph in those cases.

It would be nice to have the GPS automatically set the pedal assist max speed when riding on shared paths with pedestrians and people.

I have also seen road bikers on those same shared paths pedal faster than 20mph.

No consumer GPS is precise enough to reliably distinguish between a bike path and an adjacent regular road, especially if there are any overhead obstructions nearby. Many bike paths don't have a 20mph speed limit anyway.
