Re: Don't like coaster brakes?
Having the chain tensioned on the pedal side makes a lot of sense because the chance of disaster is now gone (no tensioner in the spokes).
Also regarding coaster brakes... some of the old ones on vintage bikes were great. Some of the new ones on cheap imports are crap. Not all coaster brakes are the same and should not be generically condemned or recommended. Depends on the quality of the brake.
Someday when I grow up I will probably lose interest in toys with wheels, but until then...
