There would be a hell of a lot less e-bikes sold in the UK if derestriction was not possible.
Brexit,actually the UK has come out rather well.

In your opinion, but that's a bit like saying that brexit leavers want to change their minds.. how can you possibly know that?
Everyone who i meet when out cycling only want to know about the speed of the bike and if it has been derestricted.The e-bikes that i have seen in my area had all been tuned up.
I would say that's bad news for all of us
It is for those who like to go a little quicker because eventualy the manufacturers will be forced by law to produce tamper proof motors.

Not necessarily. We all swapped over to 250w bikes when the UK law was 200w. Even the police were riding 250w ones. In the end, they had to adjust the law. People have been using over-powered and over-speed bikes since the laws have existed. I'm absolutely sure that authorities know about it. So far, there don't appear to have been any disasters, which makes a strong case for bringing the laws in line with how things actually are. even Bosch, Yamaha and others are really working outside the laws when they badge motors rated at 350w as 250w ones. Nobody is interested because it's no big deal.
Tell usI have a feeling that Gubs is a member of the FFP.

Would it make a PHEV ?Why does this guy have to go through all the hassle of registration etc.At least walkers and cyclists can hear him coming round a blind bend.
Convert to an eMTB but with the strimmer motor charging a small battery.
He could go for miles and when he arrived he could edge the lawn as well.
I see an opening for Gtech ???
Yes. If it was the one battery on the bike, definitely illegal, since current from the generator would be going directly to the motor as well as charging. That makes it a petrol vehicle with electric transmission, another form of hybrid.

... Being deliberately provocative..
It would be relatively easy to make an electronic switch which would disconnect the battery from the motor during the charging cycle and disconnect the generator during the charging cycle. With say a stop time of 5 microseconds between phases and a cycle rate of 1000 per second. Excess charge generated during the motor phase could be stored in a capacitor, so storing energy.
It would be fun to test the legality of that!
Superficially that could theoretically be legal, but it's questionable whether such a system could be tested using the EN15194 standard, so might not be able to be approved.
More importantly though, given the legal restrictions on our very limited power motors, the drive power downtime could halve the existing power and more than halve the drive experienced. I doubt a future limited to a true 100 watts of drive to the road would be popular with e-bikers.
The simpler solution now that high current delivery batteries are much lighter and smaller is two batteries. One on charge from the small generator and one delivering current, the two automatically switching roles at optimum intervals. Since lithium batteries are suited to cyclic charging, this is entirely practical.
.
I should add to my above post that my solution is only in consideration of the electric assist bike regulations. The authorities might well still rule that carrying an operating generator on an electric vehicle brings it within motor vehicle law on the grounds that it comes under exhaust emission regulations.
With a small two stroke generator that could be problematic.
