An electric race car track/set

I’m looking to buy an electric race car set, you know, build the tracks, 2 cars and zoooom… race your cars around the tracks… anyone know where to find this in Taiwan ???

There’s some kind of hobby shop on the ground floor of Taipei Arena that has a track set up in it and seems to cater exclusively to toy race car enthusiasts. Never browsed, but looks like it could be pricey.
