RadMini / Re: RadMini4 - 40 kmh doesn't change max

It hasn't worked for over a year, Rad changed something, probably because US Federal regulations limit Class 1 & 2 Ebike speed to 20 MPH and their lawyers got nervous. They're always changing things, like tires or eliminating the 22 inch wheel size setting recently.

If you try to cheat by entering a different wheel size it will mess up your odometer but it won't change the top speed because the revolution counter pulse from the rear wheel apparently splits into two different paths, one to the Display odometer function which is affected by changing wheel size, and the other to some form of electronic top speed limiter which is no longer affected by changing the Max speed display setting (hardware or firmware change).

Many YouTube tutorials are out of date (check when they were posted), or people with old and different bikes make new posts without knowing your bike may be significantly different.

Thanks for the reply, it's pretty much what I suspected, unfortunately. 
I was also looking at the Lectric XP 2.0 before making this purchase.  It has option to change top speed to 28mph, then peel off the Class 2 sticker on frame to reveal the Class 3 sticker underneath.  Would be nice for that option here, seems like it would release their liability, but I'm no lawyer.

RadMini / RadMini4 - 40 kmh doesn't change max
August 15, 2021, 08:05:57 PM
New owner if a RadMini4... I see all these tips and tricks, YouTube videos, showing to change the limiter from 32 to 40 kmh.  I did that, it saves the setting, but the speed still maxes out at 20 mph, which should be closer to 25 mph with a 40kmh limit. 

By any chance did they fix it so that the limiter sticks with the 20mph max? Or what else could be going on here?
