It looks like it has a chainring clutch, though without a chainguard cover, you have the risk of clothing, body parts, shoelaces, etc getting sucked into the chain, yeah.
The motor sticks out uncomfortably close to the pedals and particularly on a MTB I could see a rider accidentally stepping on it...and it looks like an outrunner, so that would also be quite bad, as the foot would get launched backwards pretty violently.
This is a lot of effort compared to just bolting on a Baofang mid-drive motor. The components are also placed such that unless you have a pretty good front fender, they'll be covered in crap in no time.
