==Eine Biopace Geschichte== | |||
I [John Allen] bought a Bike Friday travel bike at the factory in Eugene, Oregon in September, 2005. At Portland International Airport, the TSA's x-ray machine ejected the bicycle in its carrying case like a baseball from a pitching machine, to smash into into a rigid barrier at the bottom of a chute. | I [John Allen] bought a Bike Friday travel bike at the factory in Eugene, Oregon in September, 2005.

A couple of years ago, I added a 28-tooth Biopace chainring, using the previously unoccupied 74-mm bolt circle of the Bike Friday's crankset. I haven't contrived a front derailer yet to work with the Bike Friday's unusual frame, so I have to shift the chain manually. That's OK because, thanks to the bicycle's small wheels, I only need to use the 28T chainring for very steep, long climbs. It has taken me to the summit of Mt. Wachusett, here in Massachusetts, at age 65, without walking, spinning all the way! | A couple of years ago, I added a 28-tooth Biopace chainring, using the previously unoccupied 74-mm bolt circle of the Bike Friday's crankset.
