Dear Sport/Fitness CEO,

Add a new, full body fitness product to your line of products.

vanessa DD
5 speed Cruiser with up front hand powered “Conversion Kit”.
The white bike (prototype), has the Patented hand powered front conversion kit installed on a Beach Cruiser.

I would like to license my (USA Patent # 9,073,600 B2 to your bicycle or fitness company!

DD with Shaft Drive
8 speed rear hub with shaft drive technology. (no rear chain) with the chain version of the rotating handle bars! Now available!

My breakthrough technology combines versatility and performance and the result is a full body bike that works all the major muscles.   The new chain less design looks great! The conversion “kit” fits the head tube of any bike. You choose which style bikes to upgrade! We run the drive shaft inside the front fork.

The Dual Drive Bike is pedaled with your either your arms or your legs or both. Your choice. You can pedal outdoors and enjoy the fresh air or train inside on a dual drive trainer. The cross-fit benefits extend to all aspects of all sports.  Pictured below is the chain drive “Kit” that replaces the front end.

Single speed cruiser with up front hand power “kit”.
  • The front drive conversion kit fits the head tube of any bike!
  • It’s faster, adding approximately 30% more power for those steep hills.
  • It’s easy to ride and it’s a moving, highly visible, advertising vehicle!
  • It’s the best total aerobic workout on the market that gets you outside the gym!
  • The patent enables a 20 year monopoly for this product!
  • Successfully marketed, the DD Bike has huge potential. 13 million new bikes are sold each year in the USA alone.
dual drive bicycle gives the rider a total aerobic work-out
Fits the down tube of 100 million bikes at least! You can use hand brakes but I think its cleaner with a coaster brake. You can use a coaster brake with the Shimano internal shifting hubs and they utilizes 7-8 gears that have a range equal to a 21 speed bike.

Best regards,

Ken Haan

We hope to license our product to infomercial companies and progressive bike manufacturing and fitness companies.  Imagine a 20 year monopoly on the best total fitness product on the market…one that gets you from A to B in very earth friendly fashion!

This very green fitness  product is a viable means of transportation and a way to get our overweight population back in shape. No parking hassles and no expensive gasoline.  What better way to get to the beach! It’s fun to ride and a lot easier to pedal longer distances.  Yes, it fits a tricycle as well for those of you who are balance challenged.  The conversion kit fits the head tube of any bike and transforms it into a dual drive total fitness bike.WP_20150416_11_18_14_Pro

We are seeking like- minded fitness partners!  We plan to build a bike company by first introducing the bike along the beaches of California and Florida.  The bike is a highly visual advertising vehicle.  We also have in the works a dual stationary trainer that allows an individual to train at home  during the cold winter months.  It’s nice in Florida year round so getting outside for some fresh air is always on the agenda!WP_20141008_16_32_52_Pro
