I like the logos in the second row, though I if you could make it even simpler, that would be great..
Have you considered having just an outline of a house with reverse handlebars (like the first logo) for the roof, and maybe a cycle bell where the chimney should be?
I think that would look good..
Hope that helps..
Good work so far.

I tried something something like that, but it didn't look good at all. Thank you for the comment
