I have recently bought an ADO A20 and being a UK user have found that the 350w rear motor is illegal so wonder about fitting a 250w 20" rear wheel to replace it .... can anyone help?

Yes, that is technically illegal. So also are the full speed throttle and 35kph maximum speed (if it's unlocked); you are more likely to have legal issues with those, but any issues are very unlikely.

The nominal power of a motor is the slightly silly parameter used legally; most 250w motors go to at least 500w and often 750w peak. Also, it is not uncommon for the same motor to be stamped 350w for the US market and 250w for the UK/EU one.

If you changed the motor you would probably need to change the control system as well to make it legal, almost certainly not worth the cost. Even though I am a largely law abiding citizen I'd be inclined to ride it (carefully) as is; otherwise return it (if at all possible) or sell it on.

I guess 'electric scooters London' are not too concerned with the detailed legal aspect of what they sell, as almost all electric scooters are illegal for UK roads/bridleways/cycle paths/etc. I don't know if you can use 'unfit for purpose' as a reason for return.

One trouble with that bike is that the fat tyres somehow make it look as if it might be illegal, and so could attract attention.

Hoping, then, that the A20 I have with a 350w motor, will be 'under the radar' and not attract any attention from the cops ... unless I have an accident! The A20 tyres are 20" x 1.95 so shouldn't attract the 'fat tyre chasers' either .... well, some strategic 250w stickers and my fingers crossed should do it ....

This is the extent of Police enforcement...

Any motor beyond 250w is still illegal to use on lanes and cycle-paths - it's for use on private land only with the landowners permission. In all seriousness, provided you don't ride like a nutter carving everyone up, you'll probably be okay.

Why didn't you buy a 250w version instead - something like a Fiido D4S? It looks almost the same, but legal.

I'd skip that part. In the very unlikely situation you are challenged and they look carefully at the bike that will indicate intention to break the law.

you'll be fine - the A20 comes restricted to 25kmh / 250w as standard and the chances of the police being interested in it are about the same as winning the lottery.
I have a D4s and never have any issues inspite of unlocked 32knh speed and throttle.
With all the scooters to worry about and the bikes with hub motors that look like dustbin lids bikes like ours aren't even on the radar.
How are you liking the A20? am tempted to get one for slightly higher speed and suspension

The ADO A20 seems very good so far .... I'm going to check the range I get on a battery charge as I, 15st 6lbs, don't seem to get that far ...
