Significats de propel a bike en anglès

Getting along when you're working as one, to propel a bike at speeds of 70kmph around a track, must surely be an advantage?

For the sake of comparison, the V-twin engine in the 2002 Yamaha TZ250 made 86 horsepower to propel a bike that weighs 229 pounds.

Each DC-brushed motor produces 30 kilowatts (40 horsepower) peak and 16 kilowatts (21.5 horsepower) continuous to propel a bike that weighs 320 pounds.
