This is a PreCor commercial elliptical just like in gym. Has heart rate monitors in handles, automatic elevation and resistance. Wide foot rests for stability to go backwards or forwards. This unit is self powered with a rechargeable battery. New battery 10 months ago. Also has adapter port to run off 110v but not needed with battery. Moved it into garage for easy pickup. Had to make room for “latest and greatest” . Check out on line they go for north of $1500. First $550 at my door takes it. Not waiting on anyone if you get here first it’s yours. Base mat included as well Prefer local but will ship. All shipping will be responsibility of buyer.
