While not a tsunami of trikes, I am seeing increasing numbers of trikes (upright ones like this http://www.torkerusa.com/bikes/utility/2012-tristar ) being used for commuting and errand running. What is interesting is that the riders are not the older demographic I associate with trikes ( I bought one for my dad), but are people in 20's to 40's. More of the riders are female than are male, appear to be not super comfortable on a bike and are mostly of Asian decent. Most are safety concisions, with lights, vests, reflecters, helmets. some are in bike specifid or close to to it clothes
My theory is that these are people who want to bike, did not do a lot or any biking previously, and are unsure of their abilities so they are going for a trike as these can't fall over. Also a trike does have good carrying capacity.
Any one else seeing any thing like this?
