It's obviously a new compliant model with controller that isn't de-restrictable.
If you can't adjust speed via the display them the limit is set and is a en15194 complaint bike.

I’m looking to do the same for an e-plus folding bike, which looks very similar. 24v 250w and no obvious white wire either. I’ve seen on other posts about a HI GND and LO marked on some circuitboards and bridging between HI and Ground with a switch gives the option of legal or private land use. Will take a look inside my controller over the weekend and see if any of the above applies. Let me know if it works or you find an alternative method :)

Even if it worked, it would be a complete waste of time. 12A at 24v won't give you enough power to go past 15mph. Show us what control panel you have.

I've seen so any people online with unrestricted bikes/s-pedelecs...shouldn't the owners have to register them as a moped?

What e-bikers should or shouldn't do is up to them, the chances of being stopped are very small and as we saw in the Dalston case they didn't opt to enforce the law. The rider riding ( what appeared to be a 1kw hub or more ) was taken to court for unlawful killing and was found not guilty, he was lucky because if they had prosecuted him for the illegality he would have been found guilty.

Im quite chummy with our county's head of roads policing. He tells me they don't finger many on illegal ebikes - it's hardly a major priority - but they do catch them and do put the odd one before a court. Our county's traffic officers get training input on the subject, and trained to recognise dongles and hidden 'delimit' switches, etc.

The risk is small, but is genuine. I have to obey the law in all respects with my motor vehicles and I expect others to do the same. The law tells us that it is not their choice to ride illegal ebikes - they simply must not do so.

And finally, its all grist to the mill for the cycling and ebike hating Mail reading masses. The more people get caught, the more evidence there is of a "problem", the more likely that us legal ebike riders will get clobbered with even more onerous restrictions.

In the case of Dalston he wasn't charged with the motoring offences as it was deemed by the CPS to be "two bites of the cherry", to some degree charging him twice with similar, or at least overlapping, offences. Neverless, he took the life of an innocent person while riding like a tool on an illegal bike, and that alone must surely be justification for any sane person to simply do as they are supposed to for a change.

At best it's selfish, at worst it can have serious consequences. If you want to go quicker by a moped or a speed pedelec and get properly documented like everyone else has to.

If they put them before the courts, they must have been found not guilty. Can you find or show us a single case where someone was convicted. Either your friendly policeman is telling porkies or you are.

In the Dalston collision the women stepped out in front of the rider giving him little chance to stop or miss her, no matter if the bike was legal she would have still been hit most likely. Though speed was likely a contributing factor in that the women hadn't anticipated the closing distance, it was found the women was the contributory factor in causing the collision.

Totally agree with this

Getting rid of a speed limiter is a simple process, you just have to remove the e-bike speed limiter wire from your equipment. It is usually found at the controller and normally comes as a single wire. After removing the wire, your bicycle now lacks the e-bike speed limit, and you are free to enjoy its full speed.

The first process is probably the easiest way to remove the speed limiter on your bike. If your electric bike has limiting wire installed, you just have to remove the e-bike speed limiter wire from your equipment

Not all ebikes have a wire to just unplug mine is a cheap controller covered in resin and who knows what wire to cut if possible to derestrict it help lol

My ZIPPER brand e-bike is en15194 compliant so does that mean it's not possible to de-restrict it? I can't figure out how to change speed through the display either. BAH HUMBUG to legitimacy!

I've never found an ebike yet that couldn't have the speed limit released. Different bikes have different methods.

Five years on down the line and we are now seeing many more stories of confiscations and prosecutions , in some areas of the country esp cities now is not the time to run illegally with powerful motor and a speed controller as it is far too easy for them to run up the motor.

That said I should really plug in my TSDZ2 and remove the naughty mode.

In the absence of a 'dongle' or popular utube vid hack, the catch all solution (well most) is a replacement of the control system that contains the compliant programming with a generic model usually that will also provide more amps for torque and speed.

If lucky its a pull and plug in a replacement silverbox and display unit. - Most ebike control systems especially the generic replacements use software in both the control box and the display unit, #1 rule BUY BOTH TOGETHER to avoid communication problems.

Now if your bike can reach and maintain 15 mph ok and the battery lasts long enough for the trips you take, I would think long and hard about about making the mod to your bike.

Bikes with good brakes can handle 15 mph even with a lump like me on em, - start moving at 20mph or more and other road users wont expect you to move that fast and your stopping distance will grow. btw rolling at speed when Not downhill.. without pedalling is a dead give-away..

If its something you NEED to do, dont cheap out on the replacement controller- opt for the forum favourite KT brand. This will allow you to set a default max 15.5 mph top speed. Then if you want to negate that just enter the config and lift it.. Should you get stopped turn off the system (battery switch is probably the quickest way) and it will restart with the default speed cap as it should.. - set a security code for the settings and if asked for it by plod suggest you were never given it..
Not fool-proof nor is it advice, just information..
Depending on where you are in life you could be risking a lot for very little, if involved in a rta your non compliant pedelec would be a blame and liability magnet possibly making you the default cause and footing the bills. and if you have/need a driving licence??

Check out the Seizures thread and how frequently its updated with reports from local press..

imho if you need to move faster than the 15.5 mph pedelec speed cap, get a moped or e-moped.. or pedal faster.
