The endorphin e-resistance system features interchangeable and upgradeable modules. Customize your unit below by first choosing the desired platform: arm ergometer with table-top platform (300 series), arm ergometer with height-adjustable platform (355 series), or arm ergometer with height-adjustable platform and detachable seat (380 series). Then select ergometer crank rotation: the e1 and e4 are bilateral, while the e2 and e3 are unidirectional (e3 has less resistance more suited for nursing homes, e2 has higher resistances, more suited for athletic training). The e1 uses mechanical chain drive, while the e2, e3 and e4 use a magnetic drive. Lastly, select the grip style: comfort grip, quad grip, or multiposition grip. All units come with a body stabilizing chest pad which adjusts to a vertical or horizontal position and has a 7” range of motion. Units also have a multifunction pulse meter which reads distance, time, speed, calories and pulse.

Comes with the adjustable platform as in the 355 series above, and an adjustable seating system. The semi-recumbent seat adjusts front to rear for proper user positioning and rotates 360 degrees to provide for easy access. The seat assembly may be quickly removed to allow for wheelchair accessibility. Ships by truck.

Comfort grip handles allow the user to rotate his arms forward and backwards.
