I am getting rid of the greasy chains on my old dual drive bike. I will replace the chains with a drive shaft driven by two sets of helical gears. The front wheel drive is powered by rotating your hands. The rear drive is pedaled by your fhttps://youtu.be/cp_TRokop2Meet as normal. The drive shaft is hidden inside the right side “dual crown” front fork. This revolutionary hand-powered system fits the head tube of any bicycle and transforms it into a “total fitness bike” that the crossfit athletes of America should embrace.
As you can see, “No Chains” on the front wheel drive! I’ve run the drive shaft down inside the right side dual crown front fork and attached the unit to an inexpensive girls’ Bojon Beach Cruiser. I will attach it to several different styles of bicycles and post the pictures as they happen. The hand driven front wheel drive will fit the head tube of any bicycle! The possibilities are limitless! I am probably 6 months away from full scale production. I sent in my “Shark Tank” application…lol
