On a 3 hour charge, the Vienna Bike can travel as far as 37 miles, according to our friends over at Designboom. This is achieved when traveling at a rate of roughly 13.5 miles an hour, and with good old-fashioned peddle power mixed in with the electricity. Similar to Sanitov Studio’s Chinese-inspired cargo bike, the handy cargo box is situated at the rear end of the tricycle and can carry a load of up to 88 pounds. It’s easy to park, which is good for tight city spaces, and folds down to a size that is appropriate for the intrepid urbanite. Next question?
