2014 ZERO SR Engine Problems

MOTORCYCLE WOULD NOT ACCELERATE PAST 50-55MPH AND RANGE HAD FALLEN FROM 70-90 MILES TO LESS THEN 20 MILES. ZERO MADE EXCUSES FOR MONTHS WHY THEY COULDN'T PROPERLY SERVICE. I SPOKE WITH AN AARON SEVERAL TIMES, ALSO ZACK. ZERO THEN REPLACED THE CONTROLLER CLAIMING IT WAS DEFECTIVE AND THERE WERE NO PROBLEMS WITH THE BATTERY. I FINALLY RECEIVED THE SR BACK AND IN HEAVY TRAFFIC, THE MOTORCYCLE DROPPED FROM A FULL CHARGE TO 18% IN ONLY 16 MILES AND THEN COMPLETELY SHUT OFF WITHOUT ANY WARNING WHILE GOING ABOUT 40 MPH. IT WOULD NOT GO FASTER THEN 40MPH. I MANAGED TO MOVE BETWEEN 2 CARS TO THE SHOULDER, BUT I SMASHED MY LEG ON THE RAILING IN THE PROCESS. SR TURNED BACK ON A FEW...
