> Sweat free commute I always wonder if people aren't confusing racing with bicycling. Granted I live in moderate climate but we have our hot days too, generally it's not that hot yet early in the morning, but in that case I could dress appropriately with shorts for the bike ride and change into work clothing after. According to my phone I generally do a pretty leisurely 12-13 km/h (7.5-8 mph) on my upright (ie. normal) bike and could keep that up for hours without breaking a sweat. Bicycling is really very efficient. Looking at the way bicycling is experienced in London, and I think many US cities too, I see people dressed in full racing gear and doing 25+ km/h (15 mph+) on race bikes, which makes no sense to me for a city like that: you're sharing the street with dense car traffic, meaning any miscommunication easily turns into a nasty accident at those speeds; on race bikes you're hunched over and have less information about what's happening around you, just due to being lower and the anatomy of how your body turns to look around; and yes your body has to actually work to keep those speeds up.
