I have a lovely comfortable bike. It has 21 gears, quite an upright seating position and a comfy saddle. Front suspension. Im quite fat but reasonably fit. Dp thinks my bike isnt good for long distances and id be beyter with a road bike. Never mind that I can't afford a new bike and they look like implements of torture. By long distance I mean about 30 miles. I manage about 15 -20 no ptoblems. Would prefer less road work as im very anxious person. Am I setting myself up for a fall?
