Hi forum,

Im a big guy (130kgs+) who has recently moved from (flat) york to (mountainous) hampshire.

I have a Dawes city boost which did me very well in york but cant really life my weight over the hills down here.

So, my questions are
(1) Bearing in mind my weight....do i have many options for getting up hills or is my current bike as good as its likely to get
(2) If i did get a new bike, would a chain drive be best? i was looking at the sirocco CD which seemed good value.
(3) Is "chain drive" the same as "crank drive"?



Thanks!
