What I see related to "drift riding" are these quirky bikes that allow drifting ...look pretty fun. I've seen them advertised before
First impressions, you need a specific buyer selling possibly drift bikes, toys or similar. Alternatively, drifting related to cars, pretty popular. A "drifting experience" with a professional driver. Some brand surrounding this, just my take on it (known "drifting" stuff of today)
With the right buyer, I appraise 3 figures for "drift riding" as a domain. If it happened to be a domain closely associated with products / things that exist, such as drift bike, drift race, car drift, drift experience ...better pairings, somewhat more on point with the "thing", than riding ...something along those lines, I'd be entering the 4 figure range on it, in my opinion
Hope you get a bid. PS Welcome to NamePros
