This is a professional, fitness center design, stationary bicycle with variable, totally programmable, preset/adjustable exercises for professional trainers. It does not require electrical energy to operate, it utilizes magnetic resistance, making the machine smooth and quiet unlike the conventional exercise bikes you see at the Sear/Big -5 Sports. * I PURCHASED THIS WORKOUT BIKE ($1800 PLUS TAX) OVER A YEAR AND I USED IT SOMETIMES IN THE MORNING REGULAR EXERCISES. THE BIKE'S MECHANICAL IS WORKING VERY SMOOTHLY BUT WITH NO REASON, THE ELECTRONICS BOARD IS DIM THEN IT STOPS WORKING WITH NO LIGHT AT ALL. THE MACHINE JUST OUT OF THE WARRANTED DATE. I DO N'T KNOW ABOUT ELECTRICAL OR ELECTRONICS AND I DO NOT WANT TO MAKE ANY FURTHER DAMAGE TO OPEN THE CIRCUIT BOARD BUT I THINK IT MAY NEED SOME KINDS OF ELECTRICAL OR BATTERIES TO OPERATE THE LED LIGHTS ON THE SCREEN MONITOR. I DO NOT WANT TO COST ANY MORE MONEY TO REPAIR AND THE VERY HIGH SHIPPING COST TO SHIP IT BACK TO THE MANUFACTURER FOR REPAIR. MY GARAGE IS ALREADY PILED UP WITH THINGS AND I JUST WANT TO SELL THIS BIKE * AS IS, AND FOR PARTS ONLY! IF YOU 'RE INTERESTED OR KNOWLEDGE IN ELECTRONICS TO OPEN THE CIRCUIT BOX TO CHECK IT OUT SOMETHING WRONG OR IT JUST NEED SOME KINDS OF BATTERIES TO POWER IT UP, *. IF YOU HAVE OWNED THIS MODEL, YOU MIGHT NEED THIS BIKE FOR PARTS AND I KNOW THAT THE PROFESSIONAL BIKE LIKE THIS PARTS ARE NOT CHEAP. THE BIKE'S SEATED IS VERY COMFORTABLE LIKE ON AIR ATTACHED WITH THE SPECIAL SPRING AND IT CAN BE ADJUSTED TO FIT YOUR HEIGHT WHICH COSTS $240 WHEN VISITED THE MANUFACTURE'S PARTS&REPAIRS WEBSITE.
