I want to travel long distances with a mountain bike, and I have an army backpack that's wide, 55L, weights around 15-20kg total. I do not have a bike yet so I cannot test it, but I wonder if it won't cause problems in regards of weight distribution?
I'm planning to put it above the back tire on an attachable metal holder (the standard one) and strap it around my waist so it wouldn't fall down.
Would this work? I'm worried about weight distribution and it making me fall down, especially if I'm riding on an uneven road.
Please ask questions if you need to.
