when lived in Beijing used to commute by bike 3.5km to work, could make it in 15-18 minutes including 3-4 major junctions beating the bus even without counting waiting time, Beijing or Bangkok are perfect cities for biking in theory, completely flat as pancake plus in Beijing with bike lane separated by small fence, sadly pretty much every ride end up being angry about electric courier/freight tricycles using bike lane or blocking it, ebikes riding dangerously, cars blocking it, driving there to beat traffic jam or straight driving there in wrong direction against me and many other dangerous situations, it's miracle i didn't have accident even when following laws because most of the other people just don't do that now in Prague with pretty much zero bike lanes and hilly terrain so i don't really bother even trying to bike here, people in general respect rules more, but there are still plenty BMW/audi/Mercedes drivers who think laws are only for poor people
