I was hurried into a need for an e-bike when I showed up sweaty at work meetings. Price tags over $1000 stopped me and then I found Ridekick.
These trailers are motorized to provide that extra boost. It'll hook up to most any bike and it doesn't require panniers because it'll carry your stuff. The weight of the motor and battery are in the trailer so you don't need shocks on your bike and it won't wear through your rear tire either.
When you are ready, check it out Ridekick.com
I am a Honda Civic hypermiler (54mpg) and am always chasing opportunity to save a cup of gas. Bike riding is the best way to extend the tank when I am not coasting my Honda downhill
Stay aerodynamic !
