Out for a walk the other day, and spotted this bike, likely stolen and abandoned, at a bus stop.
What the heck is that Shimano device near the crank? Is it an automatic shifter, or perhaps a shift-by-wire type?
Trek is usually well-regarded, so I figure the shifter thing is a big step up from the "automatic transmission" bikes that Canadian Tire sold for a short time 25 or so years ago. They used weights which moved out with centrifugal force, and caused the gears to shift based on the rotational speed of the wheel.
Also, are those hub covers functional or just cosmetic?
Thanks in advance!
