Elastic tension radially suspends hoop about wheel.
 

Opposing Bellows generate high frequency in wheel suspension.
Screw force accumulation / return benefits drive train efficiency.
Throttle response generates "hub lift" for lever effect.



"Freedom of movement" expressed as elastic potential.

ERW Spans...Tires Seek the Bottom...Efficiency, True Tracking.

Conservation of angular momentum increases with speed.

"Hub Displacement and Screw Force". "Rebound Response" to Resistance...Plus for the first time in history... "Wind Resistance". Linear displacement returned as forward surge.

• Screw Force Accumulation and Return 16% - 22% increase in drive train efficiency.

• One application...Balance irregular bicycle pedal stroke.
