Can't go wrong with Canon. Excellent optics, great processors, easy menus, and easy software. They make shooting great photos easy.
I have had 4 Canons and 2 Nikons (which are also great quality), the only other brand I would consider is the Olympus for its rugged Tough cameras. Waterproof, shockproof, freeze-proof, it would make for an excellent take-it-and-forget-it camera, especially on the bike.
