This is just a starter:
Why Dutch Bikes are Better (and why you should want one) (11mins)
Points made within:
- sit up and beg is more comfortable
- skirt guard, chain guard, frame lock, step-through frame
- mudguards, kickstand, rear rack
- hub gears (if any)
- coaster brakes (sometimes)
- designed for transportation and low maintenance - not sport
Presently I have a cheapo trail bike, not very comfortable, but with useful 15 speed derailleur. My other half has a sit-up-and-beg step-through, with useful Swytch electric conversion and otherwise-not-excellent 3 speed hub gears. (Given the electric assist, the 3 speeds are adequate.)
