Running can be more intense but it's also harder on your body. If you want intensity, I would recommend changing the gears on your bike (If your bike has gears, that is) to increase resistance, so you have to pedal harder to cycle. That's what I do and it's made a noticable difference. I would try lifting too, though, because my legs bulked up a bit from that and it'll look strange if you have thin arms and bulky legs.
