We use Trek "police service" bikes exclusively at the department; we've got about 25 of 'em. They are good, solid bikes and mostly trouble free. Components are good enough to easily maintain when something does need adjustment/replacement.
In addition to maintaining this fleet, I've rebuilt and sold half-a-dozen other Treks over the last 10 years or so...All decent bikes with good resale value.
Sure, they're kind of everywhere... But decent machinery all the same.
