You don’t need to invest loads of money in a Yuba Mundo or similar cargo bike in order to go shopping for groceries by bike, all it takes is a little ingenuity and a sturdy frame.
Such as is provided by this old Raleigh Chiltern (I have seen a good number of these around Manchester). The gentleman who owns the bike informed me that the rear rack was his own creation. Quite an impressive capacity with some nice practical features including dynamo driven lights.
