Garage rain cover
The Bellabike Garage rain cover is a good alternative to a shed or a carport.
It is made from lightweight synthetic and weatherproof material that can be packed away into a small bag for storage. To prevent it being blown away in the wind, it comes complete with straps at the rear end, so that it can be fastened to the bike.
The Garage rain cover can be used for Bella 2 and Bella 4 bikes, and most other cargo bike brands as well.
