Thanks for the advice beatlloydy.
As I mentioned, my current bike is a hybrid (Giant Cypress SE). Is there a difference between a mountain bike and a hybrid other than the tyres?
I've also heard that shock absorbers are a bad idea if you are going to use it mainly on the road as the shockies absorb some of the energy you put into riding. Is this true?
I think the gearing is different on a comfort/hybrid. But then theres 2 sorts of hybrid as well. Giant for example have the elwood/cypress/innova/farrago/perrigee range which is more a road/bikepath orientated hybrid (700c wheels) nd the sedona range which is leaning more towards mountain bike (26inch wheels)
Tyres and wheels are different. I think the gearing as well.
Kmart bikes and the like are cheap and as far as i'm concerned only for a ride every now and again. The quality is poor in my experience (all my kids have elcheapo bikes) and usually have uncomfortable seats which you'll want to replace straight away. 2 out of the 3 kids bikes have flimsy plastic brake components which you wouldn't really want to trust your life with. Ok for a kid riding around the back streets but not much else.
Suspension does rob you of power-fronts not too bad but the back is. It's mainly on cheap bikes-you pay more it gets less. I had a cheap mountain bike (was free actually with the phone) with dual suspension and the back of the bike bounced with every pedal stroke. But as I said the front wasn't so bad. I dont know what suspension seat posts are like though.
I think the quality of kmart (and others) cheap bikes can be summed up with the label on their mountain and BMX bikes. "not for off road use or stunts". My daughters bike is called a "Kent offroader" and it has one of these stickers! We got that from toys r us.
bottom line-take lloydy's advice, spend $500 or so and get something safe and comfortable. You're talking some serious kilometres-dont waste time and money on a cheap bike.
If you want to save a few dollars there are good second hand bikes about-people buy with good intentions then dont use them. give ebay a shot.
