It would help to know what model bike You have because that model number can be given to any appliance parts dealer that You find locally, possibly even Sears, to get a replacement power adapter. I'm assuming Yours is like a small transformer that plugs into the wall outlet with a small cord that has a shiny metal pin on the end that plugs into Your Bike? Adapters for other Schwinn® and Nautilus® home fitness equipment can be ordered by phone at (800) 605-3369. Optional power adapter for the Schwinn® A40 elliptical, A10 and A15 upright bikes and A20 and A25 recumbent bikes. I hope that helps!

see the following details. God bless you
Be aware that the resistance is often the part that requires repair. Resistance is managed magnetically, so often if the machine is working, but the resistance isn't setting correctly or at all, check the bolts that secure the magnets. If they are loose, the resistance will slip. If the bolts are fine, check the magnets themselves by using a refrigerator magnet and see if it is attracted or repelled by the your fridge magnet. If not, the magnets have de-magnetized and need to be replaced

Error 1 on a schwinn is a generic electrical error. Check your ac adapter and make sure you're getting the proper voltage off of it. Typically an error 1 warrants a replacement of either the ac adapter, the wire harness (wires that connect the power to the console) or the console itself. If the console has batteries, change those first, then check your adapter. If the problem persists, you're looking at a more in depth problem that will require taking the casing off the machine and individually testing each component of the machine. It's usually worth at that point to pay a tech to look at the machine for you.
