The Danish mail delivery worker rides their bike in the winter. No need to jump start dead batteries or leave the engine running. No fuel, no emissions. No politics.

Look at how many bags of mail the bicycle can carry. Check out the bicycle’s wheeled stand system (see the small gray wheels behind the front bike wheel). When the worker has reached their destination, they can deploy the small wheels (think training wheels for a child) and walk with the bike.

For the Christmas and holiday shopping season, United Parcel Service (UPS) hires part-time workers to deliver packages via bicycle.

The company started bike delivery in 2008 in Portland, Oregon. I should probably say re-started, because UPS was founded in Seattle, Washington, by a young person riding his bicycle to deliver goods. This year, UPS expanded the program to Silicon Valley, California (video).

UPS can’t get all the credit for super-ultra-low-emissions vehicles (don’t forget a van still trucks these packages to a drop off site for the bike worker). Messengers, cycle couriers, and food delivery people work all year round in every major American city.
