Don't worry, Hannover has hardly any mountains. Exploring the city by bike is always a good idea.
A bike can be organised quickly at the bike station at the main station. If you have something to transport, you can rent the Hannah cargo bike free of charge at changing locations in the region. There are a variety of different bike rental systems, including electric ones.
The classic wire bike can be rented at the bicycle station at the main station, Call a Bike, as well as sprintRad.
There is also a wide selection of electric-powered bicycles.
E-bikes can be rented from Nextbike, but also from Radwechsel. At e-motion Technologies, e-bikes can be leased - both as an employer, employee and as a private individual or self-employed person.
The number of e-scooters on offer is also steadily increasing, with Lime, Tier, Bird, Voi and Bolt currently in widespread use.
