The initial description suggests a problem with the bottom bracket (BB).
If you have wrecked the joint on your cranck arm where it holds on to
the BB, tightenting won't help. But if this is a problem, crank keeps
coming loose over and over.
Misalignment of the guide pulley and cogs causes noisy operration under
all times. The gear change may be affected, and depending on the
misalignment, chain may jump between gears under load. But these are all
noisy. The BB problem is usually silent. Although such a problem is
preceeded by creaking noise during pedalling. Creaks are the first signs
when bearing-operated mechanisms need maintenance.
Apparently, there has been another problem with the drivetrain that
seems to be fixed now. Your initial problem must still be with the BB.
The problem with cheap bikes is that they are not meant for high
mileage. If you intend to keep on riding frequently, especially carrying
someone important, why not upgrading to something worthwhile.
Reliability is one gain, but comfort and improved functionality are
other major benefits. That is of course if you want.
