Fancy a free electric bicycle ride around the city centre of Berlin (Alexanderplatz)? You can rent it for free for 1 hour at listnride.de.
1 hour rental is free of charge as a part of the Sushi Bike promotion, so that you can test the bicycle before you make a purchase (you naturally have no obligation to buy the bike afterwards).
Pro-tip: make the booking ahead of time as there is a limited number of available bikes. You’ll need to select the day and hour of your choosing (Monday to Friday from 9am to 6pm) and they take 1 day to confirm your reservation.
