The Blockbuster may be one of the most versatile city bikes on the market. With its wider tires it can carry heavier loads (like groceries and children) while still maintaining a high degree of efficiency. The aluminum frame lightens things up a bit and the front hub dynamo ensures that the whole bicycle is a near zero-maintenance platform. With less aesthetic features the Blockbuster is a bit cheaper than the Diva and is arguably just as chic. After all, black never goes out of style.
