How to have a cool bike?

My friends and I plan to make more cool/fashionable bikes for children and adults. Now we have 2 designers and a factory willingly promise to assemble them for us.

Here I hope to get your suggestions about the bike market and what we can do in details to make it successfully?

Thank you Ladies and Gentlemen.

Most important are the ideas.
The bike should catch others views and must match to daily use needs.
I know, this answer is quite simple. That's life.
Cheers
Jens
