As of Jan 2008 I added an electric motor and battery to my bicycle and began commuting to work.  The 13.9 mile route takes me about 35minutes.  This Blog will discuss the benefits.

STATS 

As of Nov 2008 I have commuted over 3000 miles on my e-bike. In that time I've recharged my LiFePo4 battery pack about 200 times at a total cost of about $4 in electricity.  That same distance in my truck would have cost me $600.  So far I've saved $427 which is about the cost of my first electric kit.  Now that doesn't include my LiFePo4 battery upgrade which added about $1000 to the price.  I figure I'll break even in another year or so.  Then I'll be saving about $2000 a year in fuel until I have to replace the batteries again in 20 years.  That will add up to a total saving of around $36,000.  Did I mention that I'm not concerned with high gas prices anymore?  To boot, I've lost about 10 pounds and have legs of steel.
