The Hanebrink X-5 Electric Bike ($16,940) weighs less than Becky Johnson did when you dated her in the 9th grade, and that’s a good thing when it comes to getting the most miles per charge. Getting the bike to weigh just 120 pounds meant building the chassis out of aircraft-grade aluminum tubing. Hanebrink says you can go 200 miles on a single charge, and the 14-speed transmission enables a top speed of around 80 mph. Of course when the battery goes kaput, your legs can do the work. Or you could call Becky Johnson up and ask for a ride, but we heard she doesn’t give those anymore.
