Polaris Vector

Polaris Vector

Though many scoff at electric-assisted bikes, the hybrids are serious options for commuters who want a boost. The Polaris Vector can cruise at 20 mph for up to 10 miles – without pedaling. And unlike many others, its motor, which fluctuates between 60 and 600 watts, can engage both to assist pedaling and act as a dedicated throttle. [$2,500; polarisebikes.com]
