Also all that about being ”easily upgradeable”. Only b/c something is mechanically possible doesn’t guarantee that it’s economically sensible. Bike parts are a lot more expensive when bought piecemeal as compared to when bought as complete assemblies. Buying + upgrading an entry-level bike will cost more than buying a mid-range bike straight off. What is means is that Maverick knows it’s a fairly low-end bike, but are trying to sweeten the deal by saying it doesn’t have to stay that way.
It’s better than a department store bike, and is likely to hold up well to fairly enthusiastic riding. But not a bike fo the truly dedicated riders.
