>>960979Suspension on bikes, brings energy losses.
So completely useless if th most off-road you'll do is paved hills.
Men's Mongoose AL DXR 21 looks like a kiddy bike.
Wouldn't even buy if free.
schwinn trail seems like a decent comfy bike.
But since saddle is that low you will be very upright which is not very aerodynamic. Like pic related.
It's not bad, it's just slower.
If you don't commute large distances it's fine.
A typical roadbike would likely be best for you.
