How many of these entry level forks will ever be serviced? What owner at this price point is either going to pay a shop to rebuild this turd or have the know how to diy it? Can you even find a seal kit?
A year from now it will be frozen solid or close enough.
For the real world use the build on these bikes really does suck. It would be much better to have your money go almost anywhere besides the fork . Better rims and tires would be my first choice. The cheap Shimano hydraulic brakes would be awesome. A wide range 1x8 drivetrain built with a heavy but bulletproof e-bike casette would eliminate 90% of the annoyance casual riders have with their bikes.
