I can see what you are trying to do, but it reminds me of somebody sitting at a tall desk. I need it to look like the person is working out, not hanging out.
#54 & 55 do not look like indoor spin bikes to me. The logo needs to look a little more athletic. Maybe somehow incorporate a dumbbell or barbell in with the logo. I also am a personal trainer as well as a cycling instructor. (spinning instructor).
