Likes: Clean, simple design, with no shifters and cables, and one coaster brake and two gears. This Sturmey Archer hub, quite different from the SRAM 2-speed hub on the GT Meatball, shifts from "low" to "high" gear and back when you kick the crank back halfway, not far enough to activate the brake. This technology has actually been around for generations (I put one on my Schwinn Stingray as a kid) but is rarely seen today. Too bad — it works. For normal braking, apply normal backward pressure. There's a very short learning curve. Other features include rack and fender mounts, a see-through chain guard, an attractive crystal-red paint job and a far lower price than the Meatball.

Dislikes: No quick-release hubs and no fixed gear. Also, it changes gears every time you brake, which can be annoying at first.

Price: $429. (800) 283-2453; http://www.torkerusa.com
