Sorry...Not trying to be harsh, but I'm not seeing trendy or memorable here.
I do think you're on the right track though, with experimenting with bike shapes to play with a house image. I think you can let yourself push the bike images in the abstract direction. If this group is for bike enthusiasts, they'll likely recognize any bike part you use, whereas everyone else will just see an odd shape.
I'd stick to black and white for now.... BUT, when you do get to color, I like the scheme you're using with the dark and light blue.

Thank you for the comment, I think the abstract bike part idea is really good. I would experiment with it as well.
