Destricted Kalkhoff Sahel i360?

Does any one know where I can get a World Super Bike Ducati ?. I really don't care about any of the that taxed,MOT,Type approved,insured and license nonsense.

On the Kalkhoff Sahel i360, the speed is limited to 15 mph by the pass frequency of a rear wheel magnet and sensor. The fastest pedal cadence (rotation) with the Impulse motor at it's maximum 4300 rpm is 87 rpm. In top gear the cadence at the 15 mph speed limit is 65, so if the speed sensing is defeated, without any other change the assist limit would increase by some 34% to roughly 20 mph at the 87 cadence.
The only possibility to readily defeat the current speed sensing limit would be to move the magnet to the chainwheel or crank with the sensor mounted on the motor unit adjacent to it and able to read the magnet passes. Since the crank rotation in top gear is much slower than the rear wheel's, that should permit the increase. However, I can't guarantee this would work on the Impulse unit since the makers may have built in some kind of defeat to prevent this dodge, but I haven't heard of one.
If this worked, any further increase in the assist speed would have to be by reducing the number of teeth on the rear chain sprocket, but this would affect the low gear climb ability of course.

Hmm a pedal cycle doing about 20 mph with a bit of electric motor help, or a motorbike that'll do 200 mph and 0 to 100 mph in about 3 seconds, what sort of person makes such a comparison?
Just pointing out where do you draw the line. Not even saying the line is fair just fed up with people thinking it does not apply to them and not just for ebikes. If you dont like the line then get it changed not just ignore the law because if we all did that anarchy would reign
Like we need your permission
Besides, alot of unjust laws have been overturned and repealed by people ignoring them. The womens suffrage movement is a good example.

EBRA. Count me in.
there is too much legislation in this country and this has hindered the development of the ebike here in the UK, as it did in the last century with the motorcar. Nor has there been call for legislation of ebikes, as so far as i am aware, there has been no serious accidents involving them. While the prospect of twelve year olds running around central London on 1000watt ebikes should no doubt be discouraged, if the legislation was properly considered from the beginning our towns and cities would be healthier, less congested places to live with a bit less of the ruinous effects our obsessive car culture (and regulation) engenders.
I'm sorry, what was the question again?

No you don't need my permission and are never likely to. If you can't see that this attitude of I'll do what I think is right and ****** everyone else is what is generally wrong with society today then I'm not surprised as that is the attitude of most.Like we need your permission

The woman's suffrage movement broke laws as part of a campaign to get the unjust law changed not just because they thought it did not apply to them. As I said if you think current law is wrong then campaign to get it changed.
Fair comment. But you know the likely hood is they live some where that a law similar to UK is enforce (most of Europe/australia/china) or even more restrictive (parts of USA)
All very fair comments which in the main I fully agree with as I said its the attitude not the law I have a problem with.there is too much legislation in this country and this has hindered the development of the ebike here in the UK, as it did in the last century with the motorcar.

As far as I'm aware 1000 watt motorcycles are already perfectly legal to buy and ride provided they are taxed insured and you you have a licence. And my in my experience no law what so ever will stop a 12 year old using one if they can get their hands on one

So would I be correct in saying that you never ever break the speed limit when you go out on your Ducati Garry?
Or how about this, what is so wrong about doing 20 mph on an Ebike that has been tweaked compared with say doing 90 mph on the motorway in your car or on your Ducati, that's deemed perfectly acceptable, even the police don't enforce the 70 mph limit.

The tweaked Ebike is ilegal per se, it's no longer legal to use it or to enjoy the freedoms afforded to bicycles. It's not a speeding offence to be propelled at 20 MPH on an Ebike, it's a construction and use offence, a licence offence, an insurance offence, a VEL offence, and possibly an MoT offence.
The Ducati, like nearly all legal motor vehicles, is easily capable of exceeding statutory speed limits and there are penalties for doing so if caught. The difference is, it is legal to use the Ducati on UK roads. Now, if the Ducati was a track race prepared machine, not type approved for road use, the offences would be similar to the tweaked Ebike offences.
This is just the way it is and I don't think that blatantly breaking the legislation is the way to get it changed. You need to start a proper organised campaign and put forward a reasoned case for a change in the law. Finger pointing at other law breakers and accusing responsible owners of being supporters of a nanny state or of having a holier than thou' attitude is self defeating and you will lose your argument. It's childish at the very best.
If you want a bit more speed or power out of your Ebike, just get on and do it for all I care, but don't start bragging about it and organising races in public whilst using legal Ebikes and their owners as cover.
Edit: I think the threshold for speeding prosecution is 10% + 3 MPH. So 70 MPH speed limit would be 70+7+3= 80 MPH.
Crossed with GaRRy on the last bit.

Hey Im no angel and never claimed to be but I certainly dont go out of my way on purpose to do so.
In law they are both the same illegal and 90 mph is not acceptable to the police as far im aware although 80 mph does seem to be provided the conditons allow (see if you get away with it in fog !!!!). However 80 mph on most car speedos in in reality no more than 79 so as guidelines to police says alow +10% +2mph then in reality those cars are not likely to be stopped any way.
Also as others haver stated my Ducati is fully road legel with Tax,Insurance,MOT and License to use. So the only offence I am commiting is speeding where as the 20 mph ebike is breaking a load of other far more serious laws as well. As for is the law fair and justifiable that is a completly different argument.

Artstu...the difference is the bike spec not the action. If Garry rides his Ducati within our Highway laws he is 100% legal but if you ride a derestricted ebike,however carefully/law abiding you ride the bike you are 100% illegal.
Don't misunderstand my motives,if the law decides that 20 mph and 350 watts (or even 500 watts) is legal Kudos will immediately sell bikes within the law.
Aside from the law,my personal feelings are-
20 mph limit-the natural cruising speed of a modern bike seems to be at 15 mph,so the cutoff at this speed is really annoying,20 mph would avoid the cutoff for most riders,28mph is too fast for cycle track usage
350/500 watt limit-with good controls on the bike,maybe with a progressive torque sensor and good brakes I could see a situation where more power could be safely controlled,it would be very useful on climbing mountain hairpin type roads,but it would reduce the range considerably so bigger batteries may be important.
14 year limit- maybe with the higher speed and higher power this limit upped to 16 year,to align with moped use.
But none of this would be attractive if the rider were restricted to road use only,that would spoil bike riding completely for me.
BEBA are actively communicating with the Dft over the new legislation due out in 2016. If you feel sufficiently motivated over these matters then why not write to BEBA and also get a vote on the PM's voting register to get discussion going.
KudosDave
I just find this stance to slightly faster e-bikes really odd when it's coming from e-bike riders. A casual observer might think "hmm look at all these e-biker concerns about these 20 mph machines, I guess they must be really dangerous powerful beasts, perhaps we should slow them down even more"
Putting aside the legal position of e-bikes for a minute. Would you prefer your bike to assist above the 16 mph limit? would it not make the whole experience a nicer one? Now I'm not talking about very powerful motors here, just the normal 250 W rated ones on legal e-bikes.
Or are you happy to have the current speed limit?
