 * BIKING**

What we use bikes for today has become many peoples way of life. Many people in today's world need the bikes they own to get to work and make money or to go places like the grocery store or to the gym. There are people who use bikes to do small stuff like have fun, get out of the house and get some fresh air, race friends, do tricks and just go fast. However there are those people that use bikes as a means of making money. Paper routes sometimes use bikes to get the newspaper to homes, the professional bmx bikers do tournaments to win money and there are people who race bikes for cash prizes. The invention of a bike was arguably the biggest innovation towards cheap transportation for short distances and it has created many possibilities for less than fortunate families with no car and even no job.

The very first bike that is on record is the laufmaschine. It was a great invention for its time. The design for this bike is very similar to what we use now, of course it was made of wood way back then. Here is a link to what it looks like [] As you can see it is a very cool looking bike. just like the laufmaschine the celerifere was a cool bike that was really old and unique this is what it looks like [] The celerifere had no pedals and therefore was pushed with someones feet to gain momentum. There is the bike that had one very large wheel in the front and one small wheel in the back that was rode because people though that the bigger the tire the less you needed to pedal to go farther. Here is a picture [] The bike was used a lot in the 1800's and now i doubt you could even find one to buy on ebay. As you can see there are quite a few old bikes but there are also high tech new bikes with cool gadgets and wierd things to make other things do things and im gonna tell you about em right now.

One new bike is the off-road electric bike. It is obviously run on a battery so no pedaling. It is able to be off-road in sand, snow, dirt, bumpy terrain, pretty much any surface besides wet areas. Another amazing high tech bike is the electric fold up bicycle. It will actually fold up to fit in your trunk one minute then the next be riding on electrical battery power now THAT is interesting.
