it appears to be a mountain bike, which may not be well suited for fitness cycling. I think a road bike would be better for fitness, but in any case you will have to cycle at fairly high speeds for long periods of time to get the kind of fitness benefit you get from running. I think the ratio is something like 4 miles of cycling for every mile of running, at the same heartrate, to get the same fitness benefit. If you have a heart rate monitor it might be worthwhile to measure yourself over your regular run, then take the bike out the following day instead of your run and try and cycle at the same heartrate and see if you can keep that up for the same length of time as your run.
