we will put the wheels like on the open wheel race cars 
actually no we will recess the front
the engine will be put somewhere in the back
the everything will be mounted below the frame
modify engine in future
engine > v belt 90 degrees > "jackshaft" > 420 chain > wheels
assuming 1:1 on the v belt cvt is probably around 3:1 to 1:1 and the chain will be 1:6 so 6:1 - 18:1 probably which is (in the power band) 11 - 32mph assuming stock engine performing slightly above average
plan for "a section" belt size
