Your cruiser frame probably has a 1” steerer fork, so that’s what you’ll need. Honestly there isn’t much for a low price… and if there is, then you have to “figure out” a lot of it.
I’d go for a coil fork with 2-5” of travel in the minimum $200 price range.
I hope to offer a range of performance forks for motorbikes as cheap as possible, because figuring a fork setup that’s solid, rigid, lightweight, with correct geometry, and has the travel you want has always been a problem for me at least.
