That’s not the first thing to do. The first thing to do is to make legal bike riders jump through so many hoops in order to own a bike that most people give up because it’s too much trouble. Then in a few generations, when the bike owners are outnumbered, they can start to push their bike ban.
First, make bike owners wear stupid helmets, then wear silly reflectors and safety glasses. Then make them register their bikes and make it illegal to sell a bike to another citizen without going through a dealer. Then tell the bike owners if they want to use it outside of their home they need a special permit to do so. And the bike has to be stored separate from it’s tires at all times. Anyone caught with an unregistered bike will be severely punished. All bikes with more than 10 speeds are classed as “assault” bikes and are banned.
Did I leave anything out?
