5 into 3 goes......?

Sounds like grade three math. In fact I'm talking zixingche (come on, pinyin for bike). Five people, three bikes works well. One pedals, the other rides side saddle on the rack, dare I say seat, at the back. No support for the feet most times. Everyone learns as a kid. When I had to show my residents permit at the police station, four girls and I went on three bikes. I learned that day that the person at the back hops off at red lights. Hopping on again is a feat and you discover new muscles. I have seen all combinations on bikes and scooters. The seventy year old on the back of a bike, not holding on, not scuffing feet which remained suspended an inch off the ground, in perfect balance, was precious. The mother lurching as she pedalled but with good reason! Daughter was at the back, facing backwards and smiling as she went. Son turned out to be nestled at the front underneath the handlebars. At least he was looking where they were going. No one signals. Probably just as well since space is so limited it avoids a lot of straight arms across the chops!
