Riding a tuned or deristricted EMTB is not a trivial offence and can have serious legal consequences. Also, many manufacturers can detect the use of a tuning device or deristricting method and may decline a repair under warranty if it was modified from the intended original specification. Deristricting EMTB's can also add increased loads for motors and batteries. Riding above the local law limit may reclassify the bike as a low-powered bike, requiring insurance, registration and a number plate.
Be aware of your local country laws. Many laws prohibit use of modified EMTB's. It is your responsibility to check local laws. Ignoring it, has potential implications to trail access, and risk of prosecution in the event of an accident.

Perhaps taking a page from the EV car world where some manufacturers offer performance upgrades through software un-lock. Presumably due to increase potential wear and warranty exposure?
) then getting the bike de-restricted is a legal option to explore?
it ends when gravity takes over and thats around 22-23mph for a 53 lb bike.Where does it end though?
As jumps get bigger and more challenging, we could keep going through the “just 2 or 3 mph more” until somewhere down the line you need 25-30mph to clear them.
The e-bike cut off pedal assistance speed is for road going bikes, if the bike parks etc are on private land and they’re being taken there in a van (most likely a VW T5/6 by the looks of it!
Also, and I’m sure you know this, 25kph isn’t the max speed and you can pedal faster just like the ‘normal’ unpowered bikes do, and many current e-bikes pedal very well over the limit but they’re still big heavy bikes.
Im saying an eTard is a person with an eCar and an eBike on the back. hahaha.Well, I wouldn’t describe myself as an ‘eTard’ but I understand how gravity works and that it doesn’t standby and ‘take over’ at a certain speed…
Perhaps a longer run in is in order?!
now to work on chip design etc 
Where you live that may be true. Here in the endurance capitol of the world, im running on the 28 mph limiter all day.
There is no need for the bike to be powered to 23mph but it does need to be fully powered to 28mph!!
Curious what your sources are for this.
Why do you say that? Does the Amflow have a class 1 option?
In the US there is no power drop in class 3 mode and no transition at 20mph. It works as advertised. Sure it takes a few second to select the mode when starting but its a small compromise. I rarely need it but its nice to have.
Im buying one of the two bikes for speed over 20. 20 is way to slow around here, everyone runs class 3 at minimum. Even at 28 i bounce off the limiter everyday. If the gen 4 was limited in class 3, i would never own it.
My source is I own a Gen4 S-works bike. As someone also stated it was my understanding the amflow is only a class 1 bike so if you want 28mph assist your going to have to pedal really hard once you hit 20mph on the amflow.
No i understand fully. I an on the 28 limiter all day on my current bike. Lots of steep hills here. What im saying is if the gen 4 is restricting power after 20 to 250W I wont own it period.
I've seen an email someone posted from Specialized Customer Care, that said , there was no reduction in power above 20mph when class 3/28mph was selected...
Again, I would like to see this from a dyno test and not "Bob from specialized said". What are you riding currently that you are on the "28 limiter" all day? And are you going up or down these hills on the 28 limiter? I guess I am not understanding a need for 700 watts of power going downhill, uphill sure, but if that's the case I know from experience that if your climbing with this bike (>6%) you best have some serious legs to hold 28 mph for extended periods of time. Since all we have is he said she said it has full power above 20mph... all I can say is the bike smoothly transitions over 20 mph up to 28 and you get the cutoff.
600w / 85 nm motor. And a little of both, im hitting 40 everyday on pavement downhills, im in the 30's on single track downhill, and you are trying to carry speed on the flats to climb up the next grade. There should be no cutting out at 28 but im stuck with it for now. Its BS to have limiters. Our hills are to steep and long so you may hit the bottom at 28 when climbing but your speed tapers off quickly when climbing. The 20mph limiter is pathetic and it is a joke, only way to understand why 20 is a joke is to run at 28, and if you are 100% uncorked you realize why 28 sucks azz. I hit the 28 limiter often every day, but I push going down and as much as I can going up. Pushing is the key word, some people ride like it is a race, and some people just cruise. KOMs are tough on strava here in the endurance capitol of the world, so you better learn to push if you want to be competitive. And im the slowest in my groups.
I know your terrain (I used to ride a lot in Auburn etc) and I am surprised that you can even ride E-bikes there. Or are you riding designated moto trails like up in Downieville?
