Tom -

When I was growing up my mom's friend had a Twenty and I thought it was the coolest bike... she had been afflicted with polio and although she needed arm braces to walk she was able to take the Twenty out for rides.

Fast forward some 30 plus years and I am still intrigued by folding bikes and start reading Sheldon Brown treatise on the subject and follow every link I can find on modifications and then I come across a pair of Phillip's Twenty folders that have now both been pretty modified.

Because of some health issues I cannot always ride a full sized bike and sometimes I have trouble turning the pedals over with my left leg or generating adequate power so I often find myself riding a fixed gear which makes on legged pedalling much easier.

I built up a fixed gear folder first and then found myself wanting a similar bike with a little more gear range so I could spin up hills so I built up the other bike... if I had a 5 speed I'd be lacing that up and ya know... I may know where to find a 5 speed hub with a drum brake.

My fixed gear folder that has seen some serious commuting miles in the past few years...
