It was much slower than I usually go due to a lot of wind, some “barely a path” roads along the way, the bike being a citybike meant for daily shopping, as well as the fact that I was carrying 50kg (110lbs) of luggage on my back the whole way 😄
Excuses for being a slowpoke aside, it was a good challenge for my general health and fitness journey, and a very pleasant ride 😁
Also, e-bike ;)
I would be more worried of 50kg on the back (as in rucksack I understand) while sitting for hours on a saddle. The lower spine sure wouldn’t thrive?
