If you are in the market for a wireless odometer for bicycle, there are several options available for you. There are GPS units for automobiles that will actually give you miles per gallon and can be monitored by a computer. There are units that are simply built into your handlebars that will monitor the speed at which you are traveling and can also tell you how long it is since you've gone faster than a speed limit. There are also units available that have a small GPS receiver on the handlebar that can monitor the distance and speed that you are going as well as the odometer. If you are looking for a wireless odometer for bicycle, then these are all things that you should consider. The GPS systems that come with units that are actually in cars are great in that if you are out of town and need to know how far you have gone, you can easily look up your odometer on a map and find out where you are. However, this is not something that is very practical for people who use their bicycles to commute, since the unit comes with a charger and you will have to carry the unit wherever you go. If you have decided that a wireless odometer for bicycle is the way to go, then you will first want to decide on what type of unit you would like. For example, if you prefer to have the information on a screen that is easy to read and displays clearly, you can choose from LCD and LED units. Other options include those that are equipped with flash lights. These make it much easier to see the information that you are reading, so make sure that you choose an odometer that comes with a screen that is clear and that has the features that you like.
