Video says it's an 11-32 cassette. 10 speeds with 291% gear range would just be annoying; as Russ says on Path Less Pedaled, cutting the same pizza into smaller and smaller pieces and calling it progress. Manufacturers are either cynical, or just as naive about gearing as their customers. I corresponded a bit with the CEO of SoloRock, distributor of a Mu clone I bought. During the pandemic, they couldn't find appropriate 10-speed cassettes for their Pro line - so they put on the 10-speed they could find, 11-25 (!!) and sold that for a higher price as a better bike than the 11-32 8-speed on their non-Pro bikes. A small pizza instead of a medium, sold for more to poor schmucks who have never heard of range but figure more gears just must be better.
