Build day 1... did not go well. Cheap bikes are cheap, coaster brakes suck, and saying “be careful not to accidentally disassemble the hub” in the instructions is unhelpful if they don’t tell you how to avoid doing that.
On the bright side this gave me a chance to repack the hub with bearing grease and dog hair.
Also I’ve already had to do a number of repairs on a brand new bike, including retapping a jam nut that had burrs in the threads.
Full write up after I actually accomplish something.
