Hi Im 2.05 metres tall and weigh 170kg. Im ill from high blood pressure and kidney weaknesses. I need to find a bike to be able to do light exercise but with the possibility of building up. However Im not sure what bike can hold my weight and do not trust all the bike shops since they generally just into sales and most don't really know whether there are weight limits. Can somebody please advise me on a relatively inexpensive (under ten K) bike? What are the fat-cats like? Do you get more traction and therefore safer all round road holding and ride? PLEASE help I would appreciate the advice.
