Lithium-ion technology plus bicycles are the perfect marriage for urban dwellers!

Relatively speaking it takes very little power to power an LED light bulb, or a phone, or sound plugs in your ears.  It takes a tremendous amount more to move things, especially heavy things, like people.  Inertia must be initially overcome, and then friction is an ongoing problem.  The ultimate friction reducer for people is the bicycle.  It is so perfect, the basic format has not changed from when the telephone was invented, through when Voyager left the solar system and onward -- just add ons.

Electric motors are the add on with a difference.   They conquer inertia far better than carbon fueled motors.  The two types of motors are roughly equal in dealing with friction.  EXCEPT, friction, whether air or road, is relentless, and requires your energy source to endure.

Gasoline sucks for many reasons, as those of us who have had to start a siphon know especially well, but it has about 10 times the energy density (work done per pound) of an ordinary flashlight battery.

 Lithium narrows that gap dramatically, to about three-fold.  For autos, it means Teslas still have to carry a $40,000 battery pack in the floor, weighing hundreds of pounds, in order to perform like a Beamer.   But so much weight, so much friction, so much money. 

Yet only six pounds of lithium cobalt or lithium manganese batteries will push a bike 120 miles in Kansas, maybe 75 miles in our hills, and maintain typical Seattle traffic speeds.  Actual those speeds are becoming atypical as the rush hours expand to 7 hours a day.

But wait, there's more!  the above figures are before you add your own energy, whether a relaxed pedal in the park, or a future tor former Tour de France racer.  You can increase your speed into the 30's and add 25 percent to your range!

 Perhaps most important to urban bicyclists is that electric bikes beat almost every gas guzzler to 15 and get you across the intersection first when the light changes. Remember what we said about electric motors and inertia.

The result:   you can hold your lane without feeling pressure to move near the curb and weight for the rear-view mirror of a pickup to hit you in the back.  Bikes have a right to the road, and E-Bikes make it work.  Your bike commute time can be better than a car in many cases, and if you pull back just a bit, you can arrive without wanting a shower.  If you ride mainly for pleasure, the once pleasant 10 mile outing is now 20 or 30 miles.   

 Lithium batteries take a charge about 10 times as fast as the old ones, and last about 10 times as long. 

Most of all, E-Bikes are indescribably fun to ride.  You should take a test ride to understand.  Accept the gift of the perfect efficiency of the bicycle, now augmented by lithium electric motors.  Come in and try our amazing two wheeled machines. Take 15 or 20 minutes, then look us in the eye and tells us true that it was not way cool, and we will give you a ten-dollar bill. (While supplies last). Seattle E-Bike, we make, sell and repair urban transportation for this century.
