Getting around London is tricky. I hate the tube - it takes forever to get from one end to the other. So when the opportunity to bike presents itself, its a must do.
This is a photo of me, incredibly happy as I just realized that biking from one end of Hyde Park to the next was a possibility.
Bikes cost less than 1 Pound for a ride that's under 1 hour. That's more than enough time to ride through the park, snap some shots and get to your next destination.
