Your CU900 bike has a built-in generator that supplies power. The bike does not need to be plugged in to external power in order to operate. To power on the bike, begin pedaling and the console will activate.
When initially powered on, the console will perform an internal self-test. During this time, the display may not light up for a few seconds. Continue pedaling and the display will light up. Once powered on, the console will show the the start-up message. You may now begin to use your bike.
Programming the Console
Each of the preset programs can be customized with your personal information and changed to suit your needs. Some of the information asked for is necessary to ensure the readouts are correct (age, weight).
During the heart rate control programs, your age and weight are necessary to ensure a more correct calorie reading. Learn more about your machine's calorie counting measurement.
After the console powers up, press the START key to initiate the "Quick Start" program. While in Quick Start, the time will count up from zero, all workout data will start to accrue and the workload may be adjusted manually by pressing the level up and down buttons.
The console display matrix will show just the bottom row lit. As you increase the workload, more rows will light indicating a harder workout. The bike will get harder to pedal as the rows increase. The console display matrix has 24 columns of lights. Each column represents 1 minute. At the end of the 24th column (or 24 minutes of work), the display will wrap around and start at the first column again.
There are 40 levels of resistance (display as 10 rows of light) available. Levels 1-10 are very easy workloads, and the changes between levels are set to a good progression for de-conditioned users. Levels 10-20 are more challenging but the increases from one level to the next remain small. Levels 20-30 start getting tough as the levels jump more dramatically. Levels 30-40 are extremely hard and are good for short interval peaks and elite athletic training.
The display will automatically turn off (go to sleep) after 30 minutes of inactivity. This function is called sleep mode. In sleep mode, the bike will power down most everything except for a minimum of circuitry for detecting button presses and the safety button so it will start up again if these are activated.
