I don't know of any regulation which stops people from limiting their own vehicles.  Which is what doing it in the software would be.

Now that I've thought more about it, limiting speed that low could be a safety risk especially if you're not able to speed out of the way of a bad situation. Such as being hit from behind.

[Jan Wespelaar]

I do understand the thought about not being able to speed out of the way but this is in fact a non-issue on the regulation site as most cruise controls on cars have a speed limitation function. On my Merc, this limitation start with low speeds of 20mph (whats becoming the limit in most European cities). If you set this limit on the car there is no way to exces other than canceling the cruis control function which means that I am not able to speed out of the way, and my Merc is to big to just jump between to parked cars .

As this speed limitation in my car is starting from 20mph (=30kph), I would be surprised if it wouldn't be allowed on bikes.

As for the practical side of the availability of this low speed limit setup, don't forget, 20mph is very slow. Even by freewheeling downstairs on a hill road you excess this limit. Which could, by the magic  of the electric bike, be solved on a software way as there is already the incorporated engine brake which already function I do think as there is no way to excess the in the app applied top speed.

With cruise control, if you activate the accelerator, you generally will exceed the set limit as it only prevents the car from slowing down.

Dear crissa,

Not my cruise control on my mercedes e220, not on my  presedent mercedes. It will block whatever you try to exceed and even with my present on brakes if needed.

All of which i’m sure their is not legal problem, at laest not in europe (in have no info on the states but maybe their is someone on the forum with a mercedes in the states how can verify this)

[Crissa]

Dear Jan, I did say 'generally'.

That would be a very new feature relating to accident avoidance.  (And not one that I think is particularly good - we shouldn't encourage drivers to be unsafe with their inputs on the fly.  What if cruise control gets disengaged and someone is used to cruise control limiting their accidental inputs?)

My mom's last two cars had radar-based cruise control, and would cut your accelerator input (and raise an alarm) if you tried to accelerate into a hazard it had detected.  But the normal course is that it would allow you to raise your speed, for instance to catch up or surpass another vehicle before returning to cruise without further inputs.

Anybody is welcome to post a reference to the actual regulation on limiting the maximum speeds through custom settings.

(Many trucks have top speed regulators, one carrier I drove for limited to 57 mph. )

Back to the thread. I still want to set the MAX speed in custom settings to limit the top speed to any value.

I cannot find any regulation informing any limit. (If could set custom mode to "0" I'd take it as a theft deterrent (not prevention, just "deterrent")).

[Crissa]

Sometimes things are liability instead of written law, tho, like most of the reason for the minimum cruise control speed of 20.

My experience with cruise control in the states has been that any pressing on the brakes and any significant pressing on the accelerator automatically cancels cruise control.  I can't say that I have experience specifically with Mercedes.  I would say that I agree with you that a lower allowable max speed setting would be desirable if rolling on the throttle would allow you to exceed the set speed limit in the case of an emergency.

Dear crissa,

Not my cruise control on my mercedes e220, not on my  presedent mercedes. It will block whatever you try to exceed and even with my present on brakes if needed.

As pointed out by others, the top speed and lower speed can be set with custom.
The lower speed as mentioned is generally set to around 60 mph ( 100 km ).
If your local shop is passionate about the Zero, then they can probably reprogram
the computer for you. Hollywood Electrics here in the U.S. does mine.
regen is set to stop at around 12 to 15 mph. I have mine set to go all the way
to a stop. Since they can do this, I would imagine that they SHOULD be able to
set your maximum speed lower as well. On MY bikes, this is done in the SPORT
mode with Eco and Custom being normal
Hope this helps

So it probably is not a law....


https://electrek.co/2020/03/20/cleveland-cyclewerks-us-built-65-mph-falcon-electric-motorcycle-unveiled/

The Falcon 01 can be restricted to “E-bike mode” with limits of 20 mph (32 km/h) top speed and 750W (1hp), or to “E-moped mode” with a top speed of 27 mph (43 km/h). It also features an unrestricted mode that takes full advantage of its 6kW motor with a 65 mph (105 km/h) top speed.

The Falcon BLK also sports the same restricted modes, but offers up to 12kW (16 hp) in unrestricted mode and a top speed of 85+ mph (137+ km/h).

I'd imagine that bike can't be derestricted by the user, especially not on the fly, because there's no way it would then comply with the regulations. It's going to be sort of similar to Zero's "11kW" models, except actually power limited.

It wouldn't surprise me if a bike has to be able to achieve a certain speed to be classed as a motorbike (of course varying based on what country it's in) and perhaps being able to easily circumvent that doesn't comply with regulations. That said the 60mph limit does seem too high, there are certainly bikes here in the UK that can't go over 60 but are still classified as motorcycles (both gas and electric) and they are probably available in America too.

[Crissa]

In the US, a street vehicle has to be able to go over 30mph while mopeds are limited to it.  Which is only a few miles an hour more than class-3 bicycles at limited to.

Kinda makes the whole scale of things kinda pointless, if you ask me.

[Jan Wespelaar]

Back to the thread, my goal was to use the switchable custom setting as a speed limiter for driving more relaxed without need to permanently verify my speed in towns where general speed limitations of 20mhp is installed on complete area's of 10miles around. I don't know if this policy has already entered the States but in Europe, it has become the more and more generally spread as it politically supported as a way to ban cars out of the cities and improve air quality.

Or Zero bikes are already free of air pollution, so no problem. Only driving 20mph, its a hell of a job. So lowering the top speed value would be very much help, and it can be disabled with the mode switch, it is without block the bikes capability of driving more than 30mph. In plus I find the idee of ctrlburn to use it as a anti theft deterrent very inventive, if a some really wants to steal a bike he will succeed but maybe the bike doesn't move, he would take the next bike aside as he can escape directly by using the bike.

As the servicing centers here in Belgium aren't that easy to reach by phone or email or shop, it there someone out there in the forum how is living near Zero headquarters for asking them directly if it would be possible or if there are special reasons why the present minimum value is 60mhp, because we all want off course to keep or bike reliably running.

[ESokoloff]

As a workaround (if unable to limit speed), perhaps you could use Waze (or other) app on your smart phone to alert you when your going too fast (presuming it will function acceptably for this purpose).
