This gorgeous Derringer hybrid bike/cycle was modeled after 1920's racing cycles. It sports Brooks leather saddles and polished copper rivets. When you need extra oomph, You can engage the bike's engine that'll let you cruise up to 30 mph. Its 1.8 gallon tank gets a whopping 300 miles per fill. Each Derringer Cycle is hand-built and clocks in at $3,500, which, I say, is worth every penny.
