low carbon electric bikes
Imagine riding a bike with auxiliary power to scoot you over the hills? Well, I now reside in a very hilly community and it has hindered my low carton electric bike riding significantly.
In the recent past, I have spent more time thinking about how to get back home from a ride … than actually riding.Fast forward to my introduction to low carbon ELECTRIC BIKES! My mind immediately expanded to the endless new possibilities. My first ride out on the bike trails, I could not stop smiling. I ride through this area all the time, but somehow on the bike trails it is just different. So freeing! It reminded me of years ago—-out exploring on my bike, and discovering brand new places with my friends.I really was excited and my mind was instantly racing about where I could take this revved up bundle of fun. I was surprised to learn they can go as fast as 20 mph. 20 is the legal limit, mind you) and at a moment’s notice I could get the assistance I needed when going up an incline. In other words—it gets me out there riding. This is my new-found “Vehicle of Fun”!

The electric bicycle is a new technology that is gaining popularity all over the world. This bike is a viable option for people who do not have the strength to pedal up steep hills or to pedal when carrying heavy loads. An electric bike uses a motor to do some or all of the pedaling. The electric bike is part of a group of products called light electric vehicles or LEVs. These LEVs also include foldable scooters and one-person cars. People like the electric bike because it is an inexpensive, quiet and eco-friendly alternative to a car.
