We love the attempt to merge the iconic element (bike rack) into the words. Very good submissions.
However here is what we don't like: The big 'T' in Entry #46 The fact that down curve gets lost in the icon and more resembles and 'M' The 'R' although I can see it.... will probably get lost to most non graphical eyes.
Only having the one down loop, kinda makes it look like an 'M' though I wonder it went one more down loop, and the bike element went onto the other side of the 'K' if it would look better?
