Getting around, pushbikes, scooters

[JamesKT25]

This may of been asked alreay,

Im struggling to find anything concrete and cant really remember back to 2018, does anyone know the rules around bikes and electric scooters for getting around the circuit at all?

I remember seeing a lot in the campsite we were in at the Porsche curves but cant remember much around the circuit, my uncle isnt the most mobile so we want to make it a bit easier for him to get to other areas of the circuit and also to nip to the shops in arnage.

Thanks all

Is that just within the circuit itself, are they allowed in campsite and between different areas of the track?

Thanks
