What Size Generator for Peloton / Exercise Bike? (Startup vs. Running Watts)

A Peloton or similar connected exercise bike draws a modest 150–300W during a typical ride — a trivial load in wattage terms. The 22-inch HD touchscreen display, onboard computer, and resistance motor controller together consume less power than a single lightbulb per minute of use. But the motor controller is a sophisticated piece of power electronics that is sensitive to the quality of its AC input.

Modern exercise bikes like the Peloton Bike+ and NordicTrack S22i use brushless DC drive motors controlled by inverter-based electronic controllers. These controllers receive AC power, rectify it to DC internally, and then synthesize their own drive signals. Modified sine wave power from a conventional generator introduces harmonic distortion that can interfere with the rectification stage, causing erratic resistance behavior, display glitches, or — in sustained cases — premature failure of the control board.

This advice extends directly to e-bike chargers, which are another common lifestyle load during extended outages. Electric bicycle chargers (48V, 3–5A typical) contain switching power supplies that are sensitive to THD. Always use an inverter generator or power station for any device with a switching power supply, including e-bike chargers, laptop adapters, and phone chargers.

The practical generator recommendation is any small inverter generator — the Honda EU2200i, WEN 56200i, or an EcoFlow RIVER 2 power station. At 300W running draw, you could power a Peloton for over 5 hours on a single tank of a Honda EU2200i. This category of load is really about power quality, not power quantity.
