Well they are not as good as my Eflow E3 Nitro but they work fine and the brakes have motor cutoff switches. Not sure about the rear brake not familiar with this type.
I test rode it before I bought it so I could compare it to mine and for $1900 with all the features it has it was a good value, plus the cockpit is very easy to use, thumb throttle, twist shifter and internally geared rear cassette/hub
It also was one of the few that was small enough with all of these features. Since my wife is 5"2".
