Bike Friday in hand
Got my bike today, just in time to take advantage of a free afternoon. It rode like a dream! Wish I had this bike 3 years ago!

Rad looking bike! So how does the gearing work? It must have chain rings and a rear cassette that are very different than a regular road bike, to compensate for tire size.

Hi Carrie! Wow! now I know who you are!!! I did not recognized the 'Carol' name after your first comment on Brenna and her running.
The bike uses a rear cassette (Shimano brand) that goes down to 9 teeth where-as a typical road bike only goes down to 12. This almost exactly compensates for the 20" vs.27" wheels.
A friend of mine has this plus a 62 tooth front ring (an option) which gives him 138" of gearing vs. 119" on a road bike. He likes blowing off unsusupecting big wheels with this. I decided to spare the big wheels and my legs and stick with the smaller front ring.
By the way, the gearing numbers are a flashback to the day when people road big front wheel bikes with no chains. The 138" would be the equivalent diameter of the wheel!
Cheers, Dave
