As an old age trike cyclist (86) and NEVER suited up with "the kit", it is the same here. Almost everyone on the MUP waves back when I wave, except the fully kitted riders on $5000 bikes and up. Maybe they dont see anyone, because their head is down staring at their front wheel.
Really? Head staring down at their front wheel? You think that's how they ride, do you?
Are people with bikes £4999 less friendly then than those with £5000 bikes then? Is that your cut-off for who you can tolerate sharing the roads with you before you dislike them based upon how much they have spent? Do you check Invoices to make sure?
"The kit" and "NEVER" just makes you come across as a very bitter individual anti a certain type of cyclist you don't like. Me? I welcome anyone to cycle, be that on a penny farthing, 'bent, trike, commuter, hybrid, MTB or racing bike and they can wear whatever makes them comfortable in their pursuit - no pathetic 'them vs us' here.
It's bollocks that those who 'train' or are more 'focussed' or ride expensive bikes, fully kitted out are less friendly. This whole 'them vs us' only exists in the minds of certain folk who hold a particular chip in their shoulders.
I've been cycling in many countries, in all its forms - including the UK - and there is some utter tosh being stated in this thread. Some of the most helpful cyclists in the UK - who actually promote cycling for all, who give up their free time as volunteers to help others enjoy their cycling, who organise events etc - belong to Clubs and in my experience are very friendly, despite many owning expensive bikes, training and even racing.
I don't recognise your perceived experiences. In the main, I get waves, nods etc returned from all types of cyclists I encounter on roads and trails.
