As of the middle of July, the guests and residents of Sofia have the opportunity to use the first electric bicycle sharing system Sofia Urban Challenge - everyone can rent the first 10 electric bicycles in front of the National History Museum to reach Vitosha in a convenient and ecological way. You can use the bikes every day from 9 am to 7 pm by taking them from their rack in front of the National History Museum. They are equipped with a GPS system and there is an established route to the Golden Bridges (Zlatnite Mostove). The bicycle rack is located in front of the National Historical Museum and they can be rented through a special mobile app. The website of this initiative is https://rentebike.bg – there you can find information both in Bulgarian and English and at present a special app is being designed through which people will be able to reserve a bicycle and receive more information about the route. Till then you can dial +359 885/151 928 for more information.
