Vigurvänt pedals are compatible with 9/16” threaded cranks. Generally it means 100% of bicycles, but there is also less used 1/2” thread standard that is used on bicycles with so called one-piece cranks. It’s easy to check which ones your bicycle has if you compare the crank arms.
1/2” thread owners have still one solution, please search “pedal thread adaptors” for details.
