Any problems with the Police in the UK?

It depends on the officer and the situation...

If you had been in an accident you might be in a nasty situation

At worst you could be charged with using a powered vehicle without a licence - effectively driving without a licence - but you would have had to do something fairly impressive to get that sort of trouble.

If you do get any police interest just be polite and use the 'I didnt know that' approach.

Always keep the machine maintained and wear the safety gear

There is also the fact that if you are riding at reasonable speeds you can say that you could pedal the same speed as you are running.

There is always the kill switch - and frantic pedalling lol

I've been riding for a while here and I haven't had any trouble off the old bill. I should hope that they have bigger fish to fry like catching murderers than going after people with a 50cc engine on there bike.

Buy this one https://www.ebay.co.uk/itm/36cc-4-S...as-Bicycle-Motorized-Gearbox-1HP/172971171255 (has a centrifugal clutch and reduction gear).

put it on the rear rack over the rear wheel (make a fiberglass cap over it. Will look as your luggage or something else)) , keep original bicycle Shimano gear, so that within a kill switch in a moment be able to continue riding just pedaling.

On the front install electric motorized wheel https://www.ebay.co.uk/itm/36V-250W...E-Bike-Conversion-26-Front-Wheel/122548309287 250 watts and suitable battery ,and you are completely legal with such equipped machine.
Nobody will be able to prove you are outside the legislation about your 4-stroke petrol engine behind you.

If you wish to be really and completely in the frame of the current legislation, then instead 36 cc engine put one
25cc https://www.ebay.co.uk/itm/Professi...-cutter-engine-25cc-0-65kw1-GX25/172681616953 and you do not need even hide one (French Velosex motovelo is an example) , but unlikely anybody will take a measurements of the cylinder volume to define it is 25 cc or 36cc )))

Good luck!

Hi I was thinking of fitting a 200cc 6.5 hp engine to my bike is there anywhere in the UK where I won't get in trouble for riding it
 
I have a 80cc bmx that blown up recently. but this thing was a beast and replacements coming in soon with new exhaust
I rode it in the park and nobody gave me hassle. its safer in backstreets because there's less of a chance of cops sniffing there
I consider putting lights on my bike or a speedo




and a new helmet also....
 
I’m 13 and have not been caught up to now but I have had police drive past and not seem to bother
