More Seizures

Here's an actual police stop check to show what happens:

Always carry a torch lol, and a receipt. Orificers are suspicious of speedometers? What do they do when there's a speedo/display? They didn't do the preposterously stupid no-load pedal assist speed test the techno trolls trolled about - can't do that without a display. If the dumb rozzer no-load pedal assist test turns out to not be BS, we could run our bikes headless/without display.

"When you pedal this, it's not got a speedometer on it. Most of the ebikes we stop have got a speedo on them. Speedo usually means it's going to accelerate like a motorbike, twist the throttle and it goes 20 or 30 miles per hour"

Here at 4m 42s:

Eh??
So, my bike has an led display. The only speedo is a Cateye cycle computer which must be really accurate ! Is lifting the motor wheel really the only way they are going to test for speed?

That's pretty well all they can do, but like us, when they've seen enough wheels spinning, they'd have a good idea of what 25mph looks like. They wouldn't be able to differentiate 18mph, and probably let 20mph go, but 35 or 30 mph would be obvious. That's what they're really after.

It seems very odd if they rely on the LED display for speed. Quite apart from the overrun issue, it is likely at best not to be very accurate. At worse, many dongles apparently cause it to display the wrong speed (out by a factor of 2?), or people will have applied other hack for it to show the wrong (but consistent and useful to the rider) speed.

Unlike in a car (and presumably a moped?) there is no legal requirement for a EAPC to have a speedometer at all, and no requirement for it to be accurate if it does have one.

Once took my van for mot and the speedo was intermittant. Was informed by the mechanic that it wasn't a problem as it's not part of the mot. Who'da thunk?
Both the vans in our houshold (Boxer and a Vivaro) have speedo's that consistantly read 5mph over what's being done, measured against a sat nav. So if bike speedo's are the same, where does that leave the 'Lets lift the motor wheel off the floor' test? That plus the fact they register according to wheel size that does not take account of tyre height and we're way off.

All car speedometers read approximately 10% over the speed limit - presumably to stop people suing the makers when they get a speeding ticket.

That's right. Anybody, who wants to go over the speed limit, could adjust the settings in the LCD to show a lower speed than actual. That would probably work up to about 22 mph, but it would be obvious by the wheel speed if you went much above that.

He was riding a 'stop me and buy one' bike. 9 times out of 10 having a delivery box and the hand warmers would suggest an illegal bike. Back in the day someone I went to college with had a van with a giant cannabis leaf motif on the back. He got stopped all the time. Same principle.

I don't think they had a plan after looking at the motor markings.

Other than riding it to check cut offs or disconnecting the rear brake sensor to allow some drag on the rear wheel I'm not sure how they could get any indication where the speed limit might be set.

 

[Sparksandbangs]

Just as a matter of interest has anyone on here been stopped and checked?

Where I travel would make it unlikely although the oversized controller box might be a red flag even though the motor is 250W.

Or a throttle

I do agree though that it is misleading to lift the back wheel and spin the motor up which will obviously give a false reading.

You can see the bike being tested with the wheel off the ground:

He seems to have a hand on the pedal, so that bike must be pedal assist only, and he's trying to get the motor spinning by turning the pedals. I can now see the advantage of those rubbish controllers that gave you speed proportional to how fast you pedal. I think I still have some somewhere.

 

[Nealh]

One day these idiot plods will be told it needs to be a speed test under load .
Needs someone to take a case to court to prove the theory and get exonerated .

They seem to have campaigns where they choose a day and hit a town centre for a bit of mass e-bike law enforcement.

I should be OK mind, I have a 250w motor and no throttle and never go into the centre of my town that is a beacon of art and culture i.e. Swindon.

 

[thelarkbox]

Why is delivery guy testing his motor speed while plod stand by?? Ive been pulled over a few times over the years for a random safety check lights tyres indicators etc, Not once has plod let me officiate the testing??

 

[guerney]

Do the cranks rotate a little when throttling? Perhaps the delivery dude is holding the bike steady while the cop is testing throttle top speed? Looks a heavy bike.

 

[Peter.Bridge]

It's not a very stringent test, if someone set their wheel size to 16" and their display to km/h then an indicated 20km/h would actually be 20 mph but would pass this test
