I travel a lot for business so I decided to buy a folding bike so I could still ride. As you can tell, I've become addicated to folding bikes.
The first picture is a highly modified Dahon Boardwalk. Changes include dropbars, BMX rear wheel, internal brake cable routing and new cranks. This bike performs flawlessly and is a blast to ride.
The second picture is my Bike Friday Pocket Tourist- It is equipped with a mix of Dura Ace and XTR components. I use this bike as my primary travel/communting bike and plan on doing some touring with it.
The third picture is my Bike Friday Pocket Pilot. This my is main daily ride. It rides just a well as any full size bike. I regularly do centuries with this bike.
