There is nothing wrong with that ebike (or emoto for the nit-pickers).

And just don't pay attention to all the whiners who just automatically assume because of your age you're going to be riding illegally, have no experience, are dumb, or whatever else enters their judgmental heads.

I taught all six of my boys to ride dirt bikes when they were younger than you are, and they were fully capable riders and knew how to handle bikes better than a lot of adults.

The only thing about electric dirt bikes that concerns me is how waterproof they are. We ride in muddy conditions a lot (with gas-powered dirt bikes) and I'm not sure those conditions would go well with electrical components. Of course it would probably depend on how the emoto was built.

So if you like to ride in mud, you might check on that. Otherwise, I can't think of any reason why you shouldn't get that edirtbike. I think, from the description, it would do well as a first edirtbike for a young man.
