In Australia have never heard anyone comment about my weight. I think it is because there are a lot of overweight people in Australia. I am not unusual. I feel good about myself. When I go cycling, I am not concerned what others think.
I also spend a lot of time in Cambodia. During the early visits, I would walk a lot. Cambodians would often say, look how fat he is. While I feel good about myself, It starts to get annoying after 100 times.
Since then I bought a fat bike. It is ideal in Cambodia when you go on dirt tracks, where there can sometimes be a lot of mud. Most Cambodian villagers have never seen a fat bike. Now, people often comment more about the bike, than they comment about me.
Maybe those concerned about comments could get some kind of bike which stands out. Or add accessories to the bike so it stands out. So the bike gets the attention.
