Oh yes! I love these endless days! But to bicycle 150 miles - it is not in my possibilities! The longest my distance was 110 miles.
Yes, I produced the special frame - it lock my bag to the bike frame - simple and inexpensive (free I can say) device. It is not easy in my country to find out bike accessories. Or all that is so expensive …. So, most things I need I do myself
Have many many miles bicycling without any troubles WAGATHON !!!
