This should be an interesting thread. Yesterday i went to a boot sale where i often see some chap who sells among other things second hand bikes, he has a mate who does it with him and he had two mountain bikes that he had fitted petrol engines too, it was a small like moped engine but smaller, there was a spark plug, you could say it looked like a mini motor bike engine, you pedal it like a normal bike, if you then turn on a lever the petrol engine starts up and then you operate it with the twist grip it does about 28 mph he said. And the chap bought these engines and fitted them to mountain bikes he said the engines are made in germany. Now i have an electric bike and you can only buy thm that does 15 mph max. I think thats the fastest you can use them without having tax insurance etc. But these bikes run on petrol and do 28 mph.

My question is are these bikes with a petrol engine legal to use the uk with a petrol engine no tax insurance helmets etc. I should imagine any petrol bike able to do this speed would have to be taxed and insured but doubt if they would be legal. The electric bikes max 15 mph are fine to use but would one of these bikes be legal....... ???????

You can use one to potter around your garden without any issues but I'm guessing you're asking if it's legal to use one on the road in which case almost certainly not.

I had a young lad using one of these blat past me one morning. It was actually quite funny to observe as he buzzed along on some quiet-ish country lane with a scrappy BSO. I caught up with him a little later as he had run out of fuel and was pushing it along.

You can buy these kits on ebay.

If its petrol driven it opens a whole load of construction and use regulation. My guess is that would be classed as a moped and would need to be insured and plated as such. Providing you can get permission from DVLA to actually put it on the road to begin with.

For use on private land only and bridle ways are not private land as far as I know.

I've had one of those draft me on my way home, so I doubt the 28 mph bit.
How much faster were you going?

'tis perfectly legal, as long as it is only used on private land with the landowner's permission.

The private land point needs clarification.

It has to be private land to which the public has no access, which rules out nearly everywhere.

It matters not if the member of the public would be committing a civil trespass if he/she was on the private land.

Practically, a well fenced field would be OK, but to be absolutely safe, it would be better if the gate to the field was locked, rather than just shut.

The land owner's permission is irrelevant, no person - whether they own land or not - can give you permission to break the law.

Indeed, it's who has lawful access to the land that determines its status, not its ownership. For example a pub car park would be a public place while the pub is open for business, as would a farmer's field used for a car boot sale on a Sunday - that they are privately owned is neither here nor there in these examples.
