> but with a bicycle it has to happen more often

This depends heavily on the bicycle. If you get a bicycle with hub gears and coaster brakes you'll likely be riding it until the chain literally breaks in half. If on the other hand you get a bicycle with a derailleur you'll be fiddling with it every quarter if you want to keep it operating nicely.

I got a new bicycle two years ago. It hasn't had any maintenance other than inflating the tires and replacing the bell because nincompoops keep pulling the hammer off when it's parked. Still rides like new.
