Has anyone ever seen the front hub assembly on a Mobike? Although it looks like a disc it's actually a drum and looks fixed with a single nut. It would appear at a casual glance that the front hub assembly could be used as the undriven end of a trike. I'm aware they use a lot of thief-proof fasteners and are not lightweight but the wheels look great even though they'll need drilling for a valve hole due to the solid tyres. Does seem potential there though. Good pictures showing them stripped are unfortunately hard to find.
This is the best view of the front hub and brake I can find.
