“It’s you, only faster”: Hot on the eyes, with astonishing power under the pedals, Specialized Turbo Electric-Assisted Bicycle is a ground-up design, with a combined motor plus pedaling speed that tops out of 27.9 mph. Wow. This speed demon has a custom alloy, performance geometry frame, internal cabling, regenerative braking that starts charging every time the brake levers are squeezed, and a lithium-ion battery in the down tube that charges up in 2.5 hours and fuels a full hour at top speed. At 50lbs, it’s not a lightweight as far as regular bikes, but considering the plus side…no problem. $5,900.
