While prospective car buyers kicking tires may be largely folklore prospective bike buyers do lift bikes.
And why not? Certainly if serious racing or much lifting might be involved.
But how do a few pounds matter if we are cruising leisurely? And if we are looking for exercise why would we even want—should our budget indeed so allow—the lightest bike possible? A few 'extra' pounds can also mean a more comfortable ride and a more durable bicycle.
While an electric bike typically weighs around 20 lbs more than a comparable regular bicycle the electric motor is several times stronger than the typical pedaler.
Of electric bikes, which we currently sell, full sized ones weigh from about 45 lb plus a 6 lb quick release battery, and small wheeled folding bikes around 41 lb plus a 6 lb quick release battery.
