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, and wherein the motor has an output shaft that is configured to rotate about a rotation axis;
a drive mechanism that determines a predetermined stroke length of the piston, 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 quick-connect system comprising the distal end of the piston and a first messaging head, wherein the quick-connect system allows a first massaging head to be connected or removed while the piston reciprocates the predetermined stroke length at the first speed.
