I ran into this video at Taking The Lane. It shows a grassroots organization, Bike To Work, that has 50,000 members. It shows a 6 hour time slot when the main streets were closed to cars named Carfree Day. The daily traffic looks very heavy and any extra space the bicycles can use is shared with scooters and motorcycles as well. As too often happens, when a bicycle path was built it doesn’t go anywhere that people want to go and is used less than planned.
The video certainly shows a range of modern bicycles being used.
