I do not have a KT controller/LCD/PAS.
Whenever my battery comes to the end of its life, I will be switching to a KT setup. But that could be quite a while and we'll probably all be in flying cars.

If your bike is legally configured I don't think you have anything to worry about. From what you say above, it was YOUR arm effort that was making the bike wheel go fast, not the motor. If your bike is legal, just relax, ride it sensibly and enjoy it.
Nobody is after people like you. I seriously doubt that cops anywhere in Britain are searching for people who come to a forum like this, and try to make sure their bike is compliant. There are real hooligans riding about and obvious law breaking. That's not you.
E-bike seized by police as rider was not wearing a helmet

Avon & Somerset Police seized an e-bike after the rider was spotted riding around Yeovil without a helmet.

Yeah fair point, I just don't want to get my bike crushed because I've got the wrong sticker or something.
Neighbourhood police seize more than 70 e-scooters and e-bikes from across Huntingdonshire
"The 68 e-scooters and four e-bikes, some with top speeds exceeding 30mph, were removed from the streets of Huntingdon, Hartford, Brampton, Yaxley, St Ives, St Neots and surrounding villages."
"The 68 e-scooters and four e-bikes, some with top speeds exceeding 30mph, were removed from the streets of Huntingdon, Hartford, Brampton, Yaxley, St Ives, St Neots and surrounding villages."
So this morning I went to get my bike out of the shed and the back tyre was completely flat.
So shoved a new tube in there just to be on the safe side.
Still, it gave me an opportunity to file just a little bit more from the drop-outs to get an even snugger fit for the axle.
So anyway then I got my bike up on my DIY bike stand and thought I'd try one of these police back-wheel-off-the-ground-speed-tests.
So when I'm pedalling slowly, sure enough the max speed was 15/16MPH, but If I pedal fast it would go over 30MPH.
The thing is, if you get stopped and they decide to do this type of test, how do you convince them to pedal slowly?
I could afford being abducted and trapped in the boot of one of those.
Had another go with two cheapo AliExpress magnets this time and.... speed was correct until a little over 27kph, then the controller became very confused and calculates speed = 16kph to 19kph regardless of how fast I pedalled by hand with the bike on the stand (tied the bike frame to the stand's clamp arm with rope, in case the clamp jaws failed with the motor's vibes, but it didn't). Same result when using two Cateye magnets. We're allowed 10% over 25kph = 27.5kph, therefore again, as is my bike would pass the no-load pedal assist speed limit test, if pigtailed fuzzball Jesus-beardy plod go by speedo readout alone. My BBS01B is quiet, I can barely hear it while riding, and I can't hear or feel it operating when pedalling by hand at high speed, rozzers won't be able to either - drowned out by the noise of the chain, cogs etc. Because there's no load, there's no voltage drop on the display, and my display doesn't have a Wattmeter, can't see if the motor is assisting.
My rear wheel has 14 spokes per side. Magnets = 14 is accepted by BBS01B firmware, but I can't install 14 mixed magnets without sticking thin magnets (stacking a 1.5mm and 1mm combos) onto the Cateyes and AliExpress cheapos, to make the distance to the speed sensor about 1mm.
With 7 AliExpress magnets, max speed displayed = about 7kph max regardless. Bafang controller was much befuddled and confused, but my wonderous bike of maximum awe inspirementation and absolute magnificence of the highest order possible in this universe or any other currently existing in this multiverse, passed yet again!
These AliExpress cheapo spoke magnets require glue to stop them turning on spokes. The Cateyes don't, neither does the Bafang kit spoke magnet. AliExpress cheapos are shoddily made pieces of shizz.
Two Cateye magnets will do the job, if I believed fuzzball Jesus beardy pigtailed tasermeister rozzering plod orificiers were doing this profoundly stupid test, and I most emphatically don't - curiosity got the better of me, hence this post.

I was riding a Giant E Tour E + Yamaha mid drive .
Completely factory standard testing it out on a flat road 20mPH speed limit.
No sped display on the bike.
As I passed a radar 20MPH flashing speed sign it told me to slow down as I was peddling the bike faster than 20MPH.
So I would think lifting the back wheel and cranking an e bike is not an accurate test at all of the 250W Motor cutting out at 15MPH I doubt most Police Officers know or realise this .
Whilst all this is working its self out might be best for kit bikes not to fit speed meters or e throttles .
But if set the e throttles or walk assist function will still only turn at 4MPH even with the back wheel lifted off the ground the ones I have tested YOSE and Suntour.
If we take Carrera bikes for example does the motor actively reduce the bikes speed if you are say going down hill in the highest gear and it’s reached 15MPH pedal assist ? I don not think so ?

Seen these components (photo attached ) on e bay .
For Yamaha and Similar one for Giant drive mid drive motors.
Has any one any experience of using theses gadgets .
Just wondering what the electronics experts on here think of them apart from they are a speed de restriction device.

They work fine. They have to for £179.
There are different ones that work in different ways. The ones I tried could be switched on and off with the light switch. Like that one, once fitted, they're completely hidden behind the motor cover.
It doesn't have to. Legal EAPCs are bicycles in law and bicycles have no speed limits in national law.
EAPCs only have the assist limit, but there is no way the police can detect if the motor on one is actually assisting or simply consuming some power uselessly while the rider pedals it.
Remember, the onus is on the police to PROVE their case in court. No proof, no case to answer.

No speedo, had receipt and bike situated signeage, no problem:

BBSXX(X) conversions can work without display, would suit me fine because Level 9 is pretty much all I use. I don't know how one goes about making KT conversions do the same.

There haven't been any reports in news media stating police are doing no-load pedal assist speed limit cutoff tests.

POLICE in the region are clamping down on the use of e-bikes and e-scooters. The battery enhanced scooters and bikes are becoming increasingly common, but some are being used illegally and potentially causing a danger to other road users and pedestrians. Officers are now launching an initiative...

I've placed two Cateye magnets as close as possible to the speed sensor, and the result is the same. I reckon it's a strange techno variant of scaremongering by trolls, but if it does turn out coppers are indeed stupidly testing pedal assist speed with wheel off the ground:
1. My bike would pass that test using two magnets, but would be de-restricted because the algorithm can't work out speed to cut off electrical assistance - the only way I could detect this with the bike on the stand, was by temporarily connecting the throttle - drive train too noisy otherwie, high speed pedalling by hand drowns out motor noise. Throttled or pedalled on the stand, my speedo doesn't display faster than 27.5kph, 10% above 25kph. On throttle, about 16 to 17kph immediately, but a little above 27kph is momentarily displayed, after throttle is stopped and the rear wheels slows. There's no alternative open source firmware for the BBS01B, but there is for BBS02 and BBSHD - original firmware can be replaced with open source, but can't be backed up.
2. I'd be forced to try every configurator available permutation of speed related firmware parameter. Until there's proof of this dumb test being conducted by plod, I cannot be arsed.
I've set it all back as it was with one magnet.
Two and four magnets configurations work for that dude's BBSHD. With my BBS01B there's no immediate joy, but thank you for your post and the link.I dont think its necessary. It would be a full time job trying to stop them from falling off. But the guy below tried it.
Bafang Mid Motor: Multiple Speed Magnets
Some Bafang BBSHD and BBS02 programming tutorials say Speed Meter Signals must be set to 1 or bad things happen. They are right. They are also totally wrong.talesontwowheels.com
