It'll be 50 squids for a 'normal' sized bike, £55 for a large tourer/Multistrada kind of thing, or £60 for a massive tourer or cruiser.

As I need to change Bonnie's grips over I'll only have time for two bike valets, so can't offer the 3-or-more discount, but.... there will be no mobile fee for this one, so that'll save a few quid.
It'll need bike-2 to get there for about 11:00 and you should be away by about 14:30, or maybe a tad later.
