eMTB rides count toward your fitness — because they should. You still pedal. You still get tired. You still build base. RideTool doesn't penalize you for the motor.
That's enough for RideTool to know what you were riding.
The same things you see for any ride — distance, time, elevation, heart rate, calories. If your bike has a power readout or your watch logs HR, that feeds the effort score.
