3 styles of bikes that ( I ) think could fall very close together are a, commuter, touring bike, and a Hybrid, the rest
all have there own place in terminology. Beach cruiser, Road Bike, MTB, Etc...but a Hybrid does not have to be
a commuter, as many people commute on road bikes, and might not be up to the standards of a hard core
Touring Bike, so they do have there place...Richard
