Thought there was a magnet on one of the wheels ( I think front) and one on the fork/chainstay used to measure speed. Sadly I'm just going off of pictures though since I am still waiting for delivery of my steed....
Would like to go faster!

If there is a magnet it isn't on the front, I've swapped the forks and
Rims/wheels and the signal is always still going. My guess would be the controller knows the rpm and measures based on rpm and input wheel size.

That's what I think, too. I think it's pulled from the PAS sensors on the front sprocket. Bummer - that seems harder to hack.
I'll experiment when I have the time; I'm sure that system isn't 12 unique signals coming from the sensors, so if I blocked/removed half of them, would it show me moving at half my actual speed?

Wow...that's the first I've heard of enforcement of laws against e-bikes!
I have not seen any police on trails . They actually use a radar gun or have lines in the ground they measure against? Sorry to go off topic. I am happy that speed is the decision maker, no reason a speeding none ebike can go fast and an ebike can't.

You just said the Rover motor contributes up to ~25mph. Then you imply only "other brands/models can go faster than 20mph". Last I checked ~25mph is faster than 20mph by ~25%!

The display listed 40 kmh but the announcer said 0 to 20 mph. Higher numbers might not actually be settable.

They are. I'm a RadRover owner and I set higher numbers myself.

No. Not that it matters, it's not like the bike and its current motor can push it faster than 22 or 23 MPH anyway. Because, physics...

Incorrect. Actually physics will allow the bike to go faster but the bike will cut off the motor at 40kmph.

The current RadRover, with its current specs, in real-world conditions, carrying a 150+ pound rider? Not in my experience, it won't. And I'm perfectly fine with that

Well I'm 165 and on a relatively flat surface I hit 24mph before the motor stops contributing due to the limiter.The current RadRover, with its current specs, in real-world conditions, carrying a 150+ pound rider? Not in my experience, it won't. And I'm perfectly fine with that
And as far as your "cuz physics" claim, perhaps riding downhill with full throttle doesn't qualify as physics!

Something else explains the difference, then. The Ibera rack? I dunno. I just know how fast mine's been riding, in real-world conditions.
Maybe our speedometers aren't in sync. I don't care enough about the 2-3 mph difference to want to investigate further.
And for what it's worth, riding downhill means it's not the motor helping, it's gravity.
Yes, cuz physics...

Wrong again. Just because there is a slight decline does not mean that the motor is not helping you achieve a high speed. Try riding down a small 1% hill with the motor off and then again with the motor on. You'll find the speed is higher with the motor on....cuz physics...
