We formed the Dual Drive Bike Company in November of 2012. The company is located @ Dual Drive Bike.com , 4851 NE 2th A., Fort Lauderdale, Fl 33308. We are in the “working in my garage”, prototype development phase . We hope to have dual drive bikes for sale in the summer. 
Here we are two years later in November 2014. We have a working prototypes of both the chain version and the shaft drive version.
We got our patent! Fantastic! The claims cover a conversion kit for any bike and the total chain-less dual drive bike! I believe the “Go chain-less” version is much cooler looking and therefore more sell able to the exercise cross training enthusiasts. Triathletes will love this training tool and eventually lobby the Triathlete Federation to allow it in the races! Should it be allowed…arm power? Or maybe the federation will decide you can’t use your arms during the swim portion either. Ridiculous!
The benefits of the dual drive bike are that you get a killer total aerobic workout without being stuck inside a gym. You work every major muscle group in the arms, legs, stomach, chest and back when riding this fitness road machine. This bike is for serious cross training “athletes only”! 
The dual drive bicycle is great for aerobically rehabbing pulled muscles of the legs and shoulders during the off season. “I play allot of beach volley-ball and find myself constantly using the Fitness Bike (old version) to rehabilitate my right shoulder.” It works!
Lately I’ve been riding the “New” chain version to the beach and working out the kinks. The reaction is great and people love the new “look”!
The picture to the right shows the fitness bike with the dual crown front forks with rotating handles. (Very early concept “look”) The trainer that the bike is sitting on is a product I used to manufacture. The QuickStand Trainer fits any bike and turns it into a stationary exercise bike for indoor workouts during the long cold winters. 
We don’t have that problem in south Florida. Our average temperature this February was 80 degrees.
The blue and black handle bar system pictured on the right is what the shaft drive version will potentially look like after we get funded. I will be looking for angel investors.
“The best human powered vehicle on the Planet. The dual drive bike is much more fun to ride and great for relaxing different muscle groups during a long ride.” I’ve put together a set of rollers that adapt to the dual drive bike so I can train indoors on the stationary set up during bad weather conditions.
