e scooters

Well, that's odd as site leaflets used to stipulate that such scooters were not permitted on site (disability scooters being the exception) but now there is no mention in the site rules or site leaflets unless I’ve missed it. There is, though, mention that the 5mph speed limit applies to all vehicles.

I think the top speed for e scotters is the same as for ebikes - 15.5 mph but they can be ridden only on certain areas:

the only e-scooters that can be used on public roads are those rented as part of government-backed trials.
If you own an e-scooter, you can only use it on private land and not on public roads, cycle lanes or pavements

btw for ebikes that is to say an ebike's motor will only assist to 15.5 mph but all vehicles are limited to 5mph on site.

MA, have you actually seen them being ridden around a site at the speeds you write about? If so did you query there use with the site wardens, as they should have been able to give you the Club's views on them.

An interesting set of questions regarding on site use, risk, liability and insurance though. For example how could insurance be legally effective, inforced and enforced if the scooter is being used on private land without the owners permission.

30 KpH! I haven't seen one for sale in the UK that has a top speed more than 15.5 mph (25 Kmh), and legally that is the top speed in the UK under various trail schemes.

While it may be easy it would/may invalidate any warranty and/or insurance.  In the case of my ebike that would certainly apply.

I would be interested to see one for sale in the UK that has a top speed greater than 15.5 mph? Could you share?

In the same way as if you were driving any road vehicle on private land without permission. 

What are powered transporters?
The term “powered transporters” covers a variety of novel personal transport devices which are mechanically propelled (propelled by a motor) as well as or instead of being manually propelled. It includes e-scooters, Segways, hoverboards, go-peds (combustion engine-powered kick-scooters), powered unicycles, and u-wheels.

This term does not include electrically-assisted pedal cycles (EAPCs), which have their own regulatory framework

What law applies to the use of powered transporters?
There is no specially-designed legal regime for powered transporters. This means that they are covered by the same laws and regulations that apply to all motor vehicles.

The definition of “motor vehicle” as set out in the Road Traffic Act 1988 is “any mechanically propelled vehicle intended or adapted for use on roads”. There is case law confirming that powered transporters fall within this definition (see section 8 of this information sheet).

The law aims to ensure safety, consistency, and environmental sustainability in the manufacture and use of motor vehicles. Failures to comply with these rules are criminal offences for which users can be arrested and prosecuted

Well easy to show and prove that DD, post a link for one for sale that has a top speed of more 15.5 mph. I've looked at a number of shops or sales sites that sell them but I can't find one above 15.5, so perhaps you can share?

As I said easy to prove you're correct?

There are several scooters at 45kph on the market and even more above 15kph

for example
