    Maintenance Recharging the Battery Back-Up The Commercial Series U916 and R916 bikes are both self-powered (cordless) with a rechargeable battery back-up. Typically, the bike can be operated without plugging in the battery charger. If, however, the console flickers during operation or the console display does not light up while using the machine, then use the battery charger to recharge the battery back-up.
