You just linked to a $118 box of parts (or $217 if you want it assembled). This is an absolutely trash bike.
You can get a nice bike that, while not fancy and might weigh more than it needs to, will last years and be safe provided it's maintained, for about £200-£300 ($260-$400 USD) in todays prices. If you bought a bike for $200 years ago, then this is the price bracket you were buying into, not the cheap shit. You can then get increasingly good bikes as you go to $1000 and beyond.
You seem to be be blithely unaware how shit the cheapest bikes are these days. I've had bikes where the crankset literally sheared off, where the frame's welds have cracked rather than the suspension failing, where the brake cables have snapped, where the chain has snapped, where bolts have rusted, where the plastic twist-shifters can't hold a gear and drop them as you go over cobblestones, where things have broken because the minimum wage supermarket employee who knows nothing about bikes has assembled it wrong. This will be the average person's experience with the cheapest-of-the-cheap bikes, and the only way they'd be happy with it is if they don't really use the bike much, or they keep it indoors and don't cycle in the rain, or there are no hills where they live, and so on.
It only costs a little more for a hard-wearing, all-weather bike. Not thousands more. If the most you can afford are these shitheaps, I feel sorry for you, and I recommend you look for a bike charity in your area that will sell you or give you a decent second-hand/donated bike that has been checked over by a decent bike mechanic.
