Advice on bike navigation
When you buy a bike navigation system, you should also keep the user-friendliness in mind. The more advanced the device is, the more possibilities you get, but the more you'll have to look into it as well. Another important factor is screen size. The larger the screen, the easier it will be to view the data and routes. On the other hand, a bike navigation with a larger screen isn't as easy to transport in your pocket and causes more resistance.
While it's important to take into account which type of cyclist you are, you should also consider map coverage. Roughly speaking, there are 2 types of map coverage: Europe and worldwide coverage. For most people, Europe coverage is sufficient. To be on the safe side, choose a system that allows you to add extra maps in case you want to go on holiday outside of Europe. You can simply buy the maps of the country you're going to visit.
