That looks like a decent commuter bike with a cargo rack, fenders, suspension, step-through frame, and comfortable, upright riding position.

The hub-drive motor will not put as much stress on the drivetrain as a mid-drive motor would, but it might struggle on hills and it will make changing the rear tire more difficult.

Conspicuously absent are the battery specifications, other than the obviously-exaggerated, "50-mile range." I doubt if an average rider under typical conditions will get half of that range. It is a small, proprietary, in-frame battery that could be expensive (or impossible) to replace if it wears out in a few years and this generic manufacturer is long gone.

Finally, many bike shops will refuse to work on generic ebikes.
