• Warning!!

    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.

My sentiments are the restriction should cut in at 28mph, not 20mph.
When riding some popular jump lines, a speed over 20mph is needed to clear the gap. Having the restriction kick in right when you need a little extra speed, and instead it feels like your pedaling through sand is a little disconcerting at a minimum.
Usually, on regular trail rides, it is a non-issue as I do not have a need to accelerate quickly above 20mph. And because of the 20mph restriction there are times I can out ride a pedal-assist bike while on my acoustic bike.
So, in my experience, it doesn't make sense for the cut off to be below 28mph, as there are riders that can routinely excede 20mph on their acoustic bikes.

"The new California law removes the word “continuous” from the regulation, meaning motors that are capable of briefly exceeding the 750W motor (i.e. most 750W motors), will now fall outside of electric bicycle regulations."

Does the new California law make Amflow illegal to import/buy and use?

You have to remember why the legislation/laws exist, they don't exist for MTBers, they exist because selfish idiots would ride in towns and cities at 28mph in that world and be dangerous and cause accidents. Sure a manual bike CAN hit 28mph in towns, but it's harder without the assistance. You've also got to be a dedicated rider to do so really. With a derestricted MTB like that you can find a complete novice able to hit 28mph and wipe out a person or 2 in a city.
It may affect MTBers in a jumping context, but it's safe to say the people writing the laws have NEVER taken into consideration a run into a gap jump when debating speed limits :)
Is it fair, possibly not... but it's realistic

I derestricted my levo, I have no private land. It was for everyday use. I'll do the same once they release something for the amflow but expecting the manufacturer to make it available is a stretch. The only time I miss going past 25 is when I'm riding to the trails, once I'm there I don't even notice.
Hopefully you are out of warranty. It’s fairly evident that the Brose motors can’t handle much abuse. Specialized has been warranting gen1 & gen2 motors in large quantities. Gen3 not so much. But their software does datalog so if you’ve derestricted your Levo and submit for warranty they will deny it.

All good I got 2.5yrs out of it and just sold it. The new buyer bought it derestricted and was under no illusions there was no warranty but I sold it for a sharp price so he factored that in.

Even with mine derestricted I never thrashed the motor, rarely rode in boost etc

One for @Amflow_Support to watch.

Following the recent software update that has removed the option to derestrict/remove the speed limit on the Amflow PL - Please vote to show whether this is a feature you would like restored?

Derestricting the bike is legal for use on private land and there are even race series in the UK allowing derestricted bikes: e.g Pedalhounds – Multi Stage MTB – EMTB Enduro

Thanks all.
There is a way to get round this on the new software version

I've said it a few times, but my Shimano EP6 was set to max 45km/h assistance from the shop - by a Shimano rep.
There are a few 45km/h Shimano-powered bikes available here in NZ, where we don't have legal speed restrictions.
It's not customised, it's just an available firmware setting that the shop or manufacturer can choose to install

No the laws are absolutely fine. However there are no laws preventing you going beyond the limit on private land so as the owner there should be an option.

This is not some "I want my freedom" nonsense it's about what's reasonable.

But again this is all really simple.

All bikes sold remain compliant as they are today with restriction in place and owners can apply to deresrict with the manufacture accepting some basic terms and conditions.

There is no good reason for this to affect warranty and more than anything it's simply a box ticking exercise that allows them to continue to sell the bikes compliant but also give the user the choice.

It's no business of Bosch, DJI, Shimano or anyone else what I intend to do with my bike and it's my responsibility to remain with in the law at all times. It's not their job to force compliance.

People have become way to accepting of over reaching manufacture behavor and regulation of what we do.

This is again a classic example of punishing legitimate users while the AliExpress and Chinese imported cheap bikes and scooters are everywhere on the streets doing what they want with no restriction.

The guy who buys a 6k EMTB is not the problem.
I believe most of these companies offer their motors in class 3 trim, so it's not their fault that the bike manufacturers are specifying class 1 software settings. Any bike manufacturer can specify class 3 and sell it to whoever, but if that person gets checked by a ranger at a trailhead that bike is illegal irregardless of the speed the user rides at.

Does anyone one know what firmware version new Amflows are being delivered with now, after the clamp down?
If they come with V00.08.0306 or if it's possible to upgrade to 08.0306 before upgrading to v09... then happy days.

I haven't been able to turn my bike off for a few weeks without removing the screen.
I'm thinking I might have to have the screen replaced and this will maybe loose my current region setting.
I think I'd rather unscrew the faulty screen from the bike after every ride rather than go back to 15mph.
My only hope is if the region settings are stored in the motor not the screen.
Hi mate. Is it really bad to ride the bike with the 15mph restriction? Genuinely wants to know before I get one.

Depends on who you ask. The basket brigade will try to use the argument that it's just fine and if you want to go faster - get a scooter or a moped. The reality is this: once you threw in a few pedal strokes, and that's all it takes to get you to 15mph, the motor will cut the power and you're left pedaling a heavy e-bike with extra drag of the motor internals. It feels like pedaling through porridge and that's why I got all of my Specialized Levos derestricted right away. I wouldn't even ride them if there was no PLANET3 on them. That's mainly the reason I've stayed away from Bosch and Shimano for this long - just too much hassle when it comes to derestricting them "safely" and without errors.
