Low recumbent bike , has 30 speeds
 

Each wheel has a chain going fwd to a foot lever , its

naturally in low gear , this gear is low enuf to pull a Mack truck

cause of the chains short distance to footpedals

pivot , as you push , you can release pins , that catch the

chain and move it away from pivot , for high speed ,

this mechanism has no limits , you can get any reduction

you need , start with cheap 16 tooth freewheels and

make your own foot levers , use hvy springs to return

the foot levers , you cud also create a cross over , continous

chain,cable system , w/o springs , if you pushed R pedal ,

you'd feel L pedal pushing you ,

small 20 inch wheel in back for steering ,

cutting brakes can aide high speed steering ..

you cud push a prefered pedal in turns , and a 2nd set

of pedals cud camber the wheels , for really high speed .

At 50mph , it shud feel secure , and stable ,

of course i use 6007 ball bearings in the wheels !

dont try to use common parts ,
