Folding bikes

My mum and her husband used two of those when going around Australia on their motorbike with a campertrailer.

My step dad is well over 130kg's!! They thought they were great and nice to ride.

Are you talking about the ones on ebay? I went and had a ride on one. Very small and bouncy. They have suspension.... nice and comfy... but take a heap of effort to ride any distance. Really good ones.. 'birdy' etc. are worth megabucks.

Depends on how far you want to ride it.There ok if you only want to go a klm or 2. As mentioned in another post they are less efficient than a rigid framed bike and you certainly wouldnt use it on anything other than a smooth surface. I sat on one in a bike shop while I was having repairs done to my mountain bike.Seat feels comfy but the riding position will wear your legs out and thats not comfy.
If your going to get one there are always bargains galore in the used bike sections,often new and unused for less than half price.
I bought my son a $350 aluminim mountain bike for xmas.US designed,made in china .It glides along effortlessly and is much lighter than my old chrome moly frame Kuwahara.Bikes like these cost $2000 15 years ago.

Ah okay.... I see what you are after. Several of these were ridden on the Great Vic. Bike Ride....... the riders managed very well. Go for it.
