Vintage Electric drew a lot of attention when it unveiled its retro e-bikes a couple of years ago: it managed to fuse the classic look of early 20th century board track racers with a decidedly modern electric motor. Well, it's back for another year... and it's clear that the company has learned a lot in a short space of time. Its newly launched 2016 Tracker ups both the performance and the nostalgia quotient. It's 15 percent more efficient than last year's Tracker, but produces 20 percent more torque and carries a larger 70 watt-hour battery good for 35 miles of real-world travel. At the same time, you'll find clever new touches like stainless steel accents and pewter badging.
