By bike
A very good way to get around in Ingolstadt is to use a bike. Most of the main streets have bicycle lanes and you are able to get through parks an other areas you would have to go around by car. Remember to setup your bike for traffic safety though especially with working front an back lights and strictly follow traffic regulations. Bavarian police officers are very fussy about that. Getting a 100⬠fine for driving over a red light with your bike in the middle of nowhere without anyone around except for the police man 500 meters behind you is common.
