In Japan they’re called Mama Chari, or mom’s bike, and are used to get groceries, ride to the train station and according to “halloween” in the Bike Forums, they’re considered disposable by the Japanese consumer.
They’re also quite useful and even raced in a 12-hour endurance marathon (translated) – check the aero bar basket option and more on Flickr.
The bigger the basket, the more groceries, and surprisingly the more aero.
My daily shooter is Sony a9 with a vertical grip and various Sigma lenses attached like the 14mm 1.4 Art. Find more recommendations on our store page.
