I want to buy a new bicycle which I would use to go to office and occasionally for longer rides. and my aim to reduce the weight as well as enjoy bicycling by going with groups to different kind of places, Jungle, hills, Road tours etc.
How to buy the bicycle where I can sit with correct posture? My weight is 115 kg and heigh is 5 foot 11 inch.
Should I buy geared or non geared bicycle?
Should I buy a bicycle with thin or think tyres?
