This bicycle changes the traditional style of
driving, and also meet the form of human motion mechanics, reduce body fatigue
to achieve long distance cycling. (Features)
Blue-green Double Crank Joystick Bicycle |
Currently, most of bicycles
are working by the chain and the main gear. When the chains pass through the
main gear from the central axis of the bicycle, this chain will drive the sub
gear. In this mechanical mode, the distance from center of main gear to pedal
is will be the force arm; the chain only played a role in the transmission
force. The disadvantage of this drive is: when pedal at 12 o’clock to 3
o’clock, legs needs to produce a force push pedal forward. This is the major
factor cause of fatigue in legs. When pedal at 6 to 12 o’clock, legs must do
circular motion with the pedal, at this time, legs do not give force to main
gear. This will also cause of fatigue in legs. When main gear rotation of the
process, three quarters of the movement of the legs no longer force state. This
is not consistent with the laws of human motion mechanics.
This product addresses the
above mentioned existing technical deficiencies provide a new Double crank
joystick bicycle. This product will change the traditional drive mode of bike.
This bike consistent with human motion mechanics, reduce body fatigue, to
achieve long distance cycling.
How does it work? When the
right pedal goes down, right connecting crank swing down; right joystick swing
forward with right connecting crank; right connecting rod pass through right
crank drive main gear. Main gear drive sub gear by chain. The up and down
movement of pedal, converted to swing back and forth of joystick. The movement
of the main gear is caused by connecting rod to main gear. Main gear drive sub
gear turning by chain. Right and left pedal do the reciprocation at 3 o’clock to
6 o’clock. User’s legs only need to do press down with the lift, can achieve
the bike forward motion. Feet press down 90 degree, then lift 90 degree can
make main gear turn a cycle. In this way, we can achieve a fast speed and a
high efficiency human-driven vehicle.
