These are called docks in English, columns with a hole in the middle that you push the front wheel through.

For public bicycles, these are collectively called "docking stations" (i.e. a collection of docks).

In your context, I would use something like "R&D of public bicyle docking systems" or "R&D of public bicyles with docking systems". It seems the latter may be more correct as the source text seems to imply they would develop bicyles with a docking system and market them together.

" Montreal has come up with the solar powered docking system and a high tech RFID tagged aluminum bikes that are turned into complete theft disaster. There are six bikes and six docks in each station. Users can take any available bike and then return it back to any other dock. "
