Nice little gravity bikes.
A Gravity Bike is a specialised two wheeled bicycle propelled by nothing other than gravity. Without pedals or a chain, Gravity Bike riders rely on steep gradients and gravity to reach incredibly fast speeds.
Gravity Bikes evolved from modifying a traditional BMX where a rider would add weight, alter seating and handlebar positions and change a bikes aerodynamic characteristics in the pursuit of greater speeds. More recently, Gravity Bikes have evolved to become highly specialised and purpose built machines capable of reaching speeds over 130kph from a standing push start.
Gravity Bikes are ultimately built for speed. The steeper and more technical a road or dedicated racing circuit, the greater the adrenaline rush for riders. Fitted with full protective gear including leathers, helmets, gloves and boots, Gravity Bike riding combines the thrill of speed with a love of bicycles.
Gravity Bikes and Gravity Bike racing have a long and proud history. For more than 30 years there have been hundreds, if not thousands of people around the world contributing to the growth and presentation of the sport.

The best way to commute to work for me is using my bike but I also ride a train and I'm really thinking of getting a folding bike.
Here is one folding bike that I'm interested in Dahon Briza D7, it is a simple bike and has a low step-through frame that means easy mounting and a nice, comfortable upright ride.
* Easy step-through frame and 24" wheels make this the easiest riding folding bike
* Upright riding position puts no strain on your back
* You can fold the bike without even picking it up!
* Comes equipped with front and rear fenders, as well as an integrated rear rack
* Convenient air pump built into seat post
They said that this bike feels more like a full-size bike than any of Dahon's smaller folding bikes. However, the compact folded size has the same footprint as its smaller counterparts, and can even be rolled along on its wheels when folded.
