I meant to write this up as something special in tribute of Ian May (together with some other bits I've found), but haven't found the time.
So, for all who are interested in Ian May, here is the information I received from Steve Glover, who knew him well (information is also on the In Appreciation of Merseyside Bikes Facebook page):
I can assure you he built frames and painted them at the Bebington Road address. His shot blaster was in the outbuilding behind the shop.
I only knew Ian for the final 2 years of his life - but as far as I recall he opened the shop in Bebington in 1980 with the help of his family. He did race as an amateur (3rd cat I believe) and he did raise his local profile by sponsoring local clubs and riders.
He did build a lot of frames himself - however he did also put his name on built bikes and frames, I recall seeing Simoncini stock when I took the shop on.
The shop was your typical old school bike shop - where the bell rang as you entered and Ian would step out from the workshop in the back with oily hands. When I was there his stock and the shop as a whole was a bit run down. The stock was mainly kids bikes and old cheap racers and town bikes and bits of old stock he had picked up along the way - but I know in the past he had a good reputation for his frames, custom built bikes and wheelbuilding. He always smiled and said "Lloydy (Dave Llloyd) had 2 shops come and go on the same row of shops in Bebington - yet Ians shop was still there"
As I said he was a gentleman, hard working and caring and died in the shop unaware of his illness (I was with him the previous week).
Thanks Steve for providing this information!
