How Much Does It Cost to Run an Exercise Bike or Smart Trainer in Hawaii? (2026)
Most exercise bikes use almost nothing. Magnetic resistance and the display draw a few watts; bikes with large touchscreens and smart trainers draw 30 to 100 watts while streaming a class.
A typical exercise bike or smart trainer (30 W) costs $0.016 per hour, or about $0.36 per month at 0.75 hours a day in Hawaii. Cheap to run
| Wattage | Per hour | Per day | Per month | Per year |
|---|---|---|---|---|
| Low 5 W | $0.003 | $0.002 | $0.059 | $0.72 |
| Typical 30 W | $0.016 | $0.012 | $0.36 | $4.33 |
| High 100 W | $0.053 | $0.040 | $1.19 | $14.43 |
Formula: watts ÷ 1000 × hours × price per kWh. Typical use is 0.75 h/day ≈ 8 kWh per year.
One day of an exercise bike or smart trainer (0.72 kWh) is the same electricity as
- 4.0km in an electric car
- 7.2hours of TV
- 16hours of a laptop
- 80hours of an LED bulb
In Hawaii, with electricity at 52.7¢ per kWh (source: EIA Table 5.6.A, 2026-06), a typical exercise bike or smart trainer costs $0.016 per hour and about $4.33 per year at 0.75 hours a day. That is about 187% more than the national average for the US ($0.12 per month), because electricity in Hawaii costs 52.7¢ per kWh against 18.3¢ nationally. Each $1.00 of electricity buys roughly 63.2 hours of use.
How to lower the cost of running an exercise bike or smart trainer
- Turn off the screen when not in use. The display is the main consumer.
- Use a tablet instead of a built-in screen on trainers that allow it.
- Nothing else matters here. The bike costs pennies to run.
In standby it draws about 2 W, which adds roughly 18 kWh ($9.24) per year if it is never unplugged.
