Sorry Keith, this post is pretty much all bicycles 

Hopefully, the other 19 of you readers will find something to like, though.

First, Gord (who is faster than me) provides a wonderful account of his ride in the longest bike race in Canada. It sounds like a doozy of an event, and the tale is told well.

Second, having just recently yammered on about electric-assist bicycles and other light EVs, I saw this guy on my commute home:

The inventor/operator

He has built his own Stokemonkey-style electric-assist bicycle, and it looks like it works quite well: he passed me near Lougheed Mall as I was doing my 5 km/h recovery from an especially juicy sprint to beat the light, and when I saw the electric motor, I gave it everything to catch him.

Turns out the motor is typically used in electric wheelchairs (and occasionally in robot combat). The drive was to a freewheel cog mounted on the flip side of a flip-flop hub, something used on singlespeed/fixie bikes to allow a second gear option by removing the rear wheel and flipping it over.
