I am glad to see that they are putting disc front brakes on them now.
A friend of mine had one nearly identical to this one 50cc 4 Stroke Znen Moped Euro Gas Motor Scooters
only it had drum brakes front and rear.
It nearly killed him while going down the Texas Street hill.
Folks from San Diego will know what I am talking about. Really steep, lots of traffic, one cross street with traffic light.
The brakes barely held him at a reasonably slow decent, never mind having to actually stop at the traffic light.
