Pinion Drive has arrived, Midwest Bike & Tandem is one of the first shops to show the new 18speed internal drive bikes in the US. Although the snow is coming down we received a 58cm Co-motion Klack this week. Haven’t been able to ride it but looks very interesting. 18 speeds with no overlap, each gear with the same spacing, Gates belt drive what could be better. Come on in a try it out.
