1. A percussive massager comprising:
a housing;
a piston having a proximal end and a distal end, the distal end of the piston having a bore;
a motor operatively connected to the proximal end of the piston, wherein the motor is configured to cause the piston to reciprocate at a first speed;
a drive mechanism that determines a predetermined stroke length of the piston; and
a quick-connect system comprising the distal end of the piston and a first massaging head,
wherein the quick-connect system allows a proximal end of the first massaging head to be inserted into or removed from the bore while the piston reciprocates the predetermined stroke length at the first speed,
wherein the motor has an output shaft that is configured to rotate about a rotation axis, and
wherein the drive mechanism comprises:
a flywheel operatively connected to the output shaft of the motor to rotate about a flywheel axis, the output shaft extending into the flywheel along the flywheel axis; and
a crank pin extending from the flywheel, the crank pin being operatively connected to the piston.
