Yep - definitely only want something to fang around bike paths, roads and maybe a few local trails through parks.
I don't want to shave milliseconds off my time, I don't care if it weighs a few hundred grams more than a more expensive one, and I have nothing against a kmart or bigW one. Oh - and I'll never wear lycra and clip-clop through coffee shops (not that I have anything against folk that are into that - each to their own).
If you really want to get fit, you can't do it on a pushbike. The whole idea of a bike is to make travel more efficient. I've seen the claim that only soaring birds use less energy than a cyclist over flat ground.
Think about it. When you walk or run, every step your leg stops moving and you have to pick it up and put it down for the next step. That's maybe 30% of your body weight. On a bike, you get up to your comfortable cruising speed and all you have to overcome is wind resistance. Stop pedalling and you keep moving for a lot further than you would if you stopped stepping.
Having done both, I can tell you that running is a much better way to get a low heart rate and burn energy. The problem is that you destroy your joints. I reckon it took me less than 15000 Kms to ruin my knees. On the bike, that equates to a little more than 1 front and 2 rear tyres, at about $25 each (Maxxis Detonators)
As for the claim that road riding is dangerous......bovine excrement. Except in the rain, when you've got no brakes and no grip
