The 21-year-old has joined from Eintracht Frankfurt on an initial season-long loan, with Leeds holding an option to make the move permanent.
He becomes the club's seventh addition of the summer and arrives at Elland Road with the expectation that he can provide competition in the wide areas.
But who exactly have Leeds signed, and what should supporters expect from their latest addition?
Here are eight things to know about Bahoya.
One of the most appealing aspects of the deal is Bahoya's age.
At 21, the Frenchman is still at a stage of his career where there is plenty of room for development.
Leeds are not simply signing a finished product; they are bringing in a player who has already experienced senior football in Germany but still has considerable potential to improve.
That fits neatly with a recruitment strategy which has combined experienced players such as Harry Wilson and Nico Elvedi with younger additions who could become important assets for the club over a longer period.
Bahoya has spent the majority of his recent development with Eintracht Frankfurt after making the move to Germany from France.
He leaves a club that has given him an opportunity to develop at a high level and now gets the chance to test himself in English football.
Frankfurt confirmed his departure after the deal with Leeds was completed, with the transfer going through in the final stages of deadline day.
Before moving to Germany, Bahoya played for Angers, where his performances attracted attention and ultimately earned him a move to Frankfurt.
That background is worth remembering when assessing his career so far.
He is not someone who has suddenly appeared on Leeds' radar after a handful of performances; his development has been tracked across two different leagues.
Perhaps the most intriguing element of Bahoya's profile is his pace.
He has developed a reputation as an extremely quick attacker, with reports from Germany highlighting just how significant his acceleration is.
For Leeds, that could provide something valuable in games where opponents sit deep and Farke needs someone capable of attacking space and stretching a defensive line.
It also gives Leeds another route to goal alongside the more creative qualities offered by players such as Wilson.
Bahoya's arrival is particularly relevant because of what has happened with Wilfried Gnonto.
The Italian has joined Fiorentina on loan, leaving Leeds needing another option in the wide attacking areas.
Bahoya is not necessarily a direct stylistic replacement for Gnonto, but he gives Farke another player capable of competing for minutes from the left.
That competition should be healthy for the squad, particularly over a long Premier League season.
There is a difference between signing a promising youngster who has barely played senior football and signing one who has already experienced the demands of a major European league.
Bahoya has made 78 appearances for Frankfurt, scoring seven goals during his time with the club.
That experience does not guarantee an immediate impact in England, but it should give Leeds some confidence that he is ready to compete for first-team opportunities.
The structure of the transfer is also interesting.
Bahoya has joined on loan, with Leeds having the option to make the move permanent. Leeds' own announcement described it as an option, while reports from Germany have suggested the deal could ultimately become a permanent commitment under certain conditions.
Either way, the initial loan gives Leeds an opportunity to assess how Bahoya adapts to English football before making a longer-term decision.
This is perhaps the most important point for Leeds supporters.
Bahoya should not be judged by whether he immediately produces the same numbers or moments as Gnonto.
He is a different player, at a different stage of his career, arriving into a different role.
What Leeds need from him is competition, pace, unpredictability and another attacking option for Farke to call upon.
If he can provide those things while continuing to develop, the move could prove to be a very smart piece of business.
Bahoya is therefore an intriguing final addition to Leeds' summer recruitment. He arrives with plenty still to prove, but also with the attributes to become an important player at Elland Road.
The opportunity is now his.
