Some trainers around the price point of the Snap suffer from wattage ceilings and/or floors. This means the resistance unit may not be able to reach high or low values in ERG mode without shifting up or down. This is a limitation in the functional range of the resistance unit, and must be overcome by the rider shifting.
In your example, we see people reporting similar issues where they “top out” on resistance and ERG is unable to increase resistance beyond that ceiling. So they need to shift to a harder (faster) gear on the bike, which yields more resistance.
I can’t site specific examples, but would not be surprised if the Snap has issues like this.
- Do you know which gearing you used?
- Is this the same gearing you use for regular workouts?
- Have you experienced a ceiling in other workouts besides the Ramp?
