So, if it has no pedals it is not a complete bike. Thus the vendor has no legal obligation to decorate said item with (I like this term) "Poundshop junk." That makes a lot of sense. It doesn't quite explain why some very decent bikes (Dolce Elite, in my experience) come with Poundshop pedals. There again, they are fully Poundshopped up when delivered.
This where you hit a quandary. The general public (i.e. those who, generally, do not frequent this and other fora) EXPECT a bike to be sold with pedals. Bike shops like those kinds of buyers as they will buy
any old carp low to mid-range bikes, on the whole. The more bike savvy will know what kind of pedals work for them (and here I am referring to the kind of person who does frequent places like CC) and selling bikes without pedals makes sense to the bike shops, and the manufacturers, on cost, liability and work grounds.
Everyone knows that the first thing you do when you get home with a new bike is remove the pedals and reflectors (no you are not allowed to do it in the shop, I asked, but as soon as it is out of the door it is your responsibility, so you can do what you like), but the law is as it stands so they have to go through the front door with the Poundshop junk attached
FWIW the conversation I had with the LBS owner started when I asked why there was no bell and reflectors on the bike they had just built for me (Ridley Triton-T). That was how I found out about the custom built part of it (and they were firmly in the clear as they only supplied the frame/forks, stem, seatpost and front mech clamp, I had sourced the rest for a lot less than they could)
