Mini bike having pedal as a power generator

A mini bike having a pedal as a power generator that has a handle 3 in an upper part in order to steer a front wheel 1 and that connects a front wheel 1 side and a rear wheel 2 to a bike body 9, and that drives the wheels by operating a pedal connected to a plurality of gears, and that adjusts a speed thereof using a brake handle 7 installed in the handle 3, comprising:

• a driver A that connects a pedal shaft 12 between both pedals 11 and 11′ and in which a spring 16 is installed at the inside of a connector of both sides of the pedal shaft to which both pedals 11 and 11′ are connected, and in which one end of the pedal shaft 12 and the shaft 13 are connected to a first bevel gear 14 in order to transmit rotation power generated by a vertical rolling motion due to an elastic force of the spring 16;
• a second bevel gear 22 installed to connect the other side end of the shaft 13 and a driver shaft 21 in order to transmit rotation power generated in the driver A;
• a first power transmission gear 25 coaxially installed in the second bevel gear 22 to be engaged with a second transmission gear 24 in order to transmit rotation power to a spline shaft 23;
• a clutch 28 that is positioned at the spline shaft 23 to selectively connect rotation power of the first power transmission gear 25 to a first gearshift 26 and a second gearshift 27 and that controls a low speed and a high speed;
• a first connection gear 29 and a first driving gear 30 engaged with the first gearshift 26 rotating by selection of the clutch 28 to rotate the rear wheel in a low speed;
• a second connection gear 31 and a second driving gear 32 connected to a third connection gear engaged with the second gearshift 27 by selection of the clutch to be connected to rotate the rear wheel in a high speed;
• and
• a driving controller B comprising a gearshift 34 connected to a cable 33 in order to select the first gearshift 26 and the second gearshift 27 by laterally moving the clutch 28 on the spline shaft 23.
