  Bicycles have improved aerodynamic frames. Different speed settings enable the rider to adjust quickly based on body strength and comfort. Always wear a helmet for protection.

  The below are improvements over the years. One thing to remember that a HUGE % of the energy the rider puts into moving forward is used to overcome wind resistance.

  In terms of motion….

  Lighter overall. Lighter bikes overall, lighter wheels - easier to spin up and keep rolling.

  More efficent bearings all around/ wheels cranks, etc.

  Better design of frames/bars, etc. Positions the rider better on the bike to convert his energy into forward motion Also - better positions the rider on the bike to cut the wind better - lower rider resistance.

  better tires, skinner tires - Less rolling restiance -
