Design a Logo

Ok we need a new logo for this club, Its just a we finishing touch for the club "BELFAST CITY BMX CLUB" and its new website here, any ideas?
Here is just some ideas to get you started, it should not just represent one race/jump discipline, we would maybe consider all or none of the below-----

Belfast, BMX, Jumps, landmarks, fonts or a combination of many great ideas, and we will post them here.
