Crushed another dream. So which one is best?

The RX 50's larger wheels offer better ride comfort over potholes, and slower, less twitchy steering. If you like off-road adventuring, you'll be stood on the footrests often. So less butt-hurt from the plank of wood seat.

Would I recommend owning one?


Many expensive design flaws. Not everything is fixable with aftermarket parts, or MacGyver bodges. You'll spend months waiting for OEM parts from overseas countries. Very unwise choice when it's your only mode of transport.
