No, if you ride a bike you are more likely to get cancer.
biking is good :\
i ride 5 miles to work every morning and its mostly all uphill (although im riding my old dirtjump bike which is fucking hard work) and my heart rate does get pretty high on some of the longer climbs. its good fun excersize and a great way of transport, especially through traffic thats stood still and you're just flying through everything.
start again, its good excersize and more enjoyable than running or swimming imo.
