Have you seen the reviews for these?
Bike is not good enough
Good bike, if you use it infrequently
Decathlon's response was the same, "Thank you for posting a review of this bike. Indeed it is not intended for daily use ..."

That's where real life reviews are important. These bikes are ubiquitius in Spanish hire shops, from Bilbao to Malaga. It's a cheap, sturdy, simple bike, I might go in a shop and take my time before renting the right one, but for a week I can't be bothered to fly my own bike out and I've done multiple loaded tours in Spain on these with zero issues.
