I bought 2 bikes at christmas at greater than $5000. Started off with loose cable connectors to the dashboard, easy fix but a trip the shop, Lucky they are local to SAn Diego. Then we had motor problems where the motor would cut out when warmed up and then kick back in after a few seconds. Really disrupting to riding. After two trips they agreed to replace the motors. I picked up the bikes and I rode mine for 6 miles as I left the house on my 2cd ride the pedal came loose. I took my bike in again and showed them the problem. They asked me why I took the crank arms off. I said I didn't and then I was called a LIAR several times "Your lying to me" by the sales associate. The crank arms were mounted on the wrong sides left arm on right side and right on left side. An easy mistake but caused the pedals to loosen one pedal has reverse threads. The mechanic then said I was questioning his ethics.and his competence. I was questioning his competence. The arms are marked with an L and R.and needed to remove to change motors. After much screaming they agreed to change the arms out and replace the pedals since the threads were stripped. The ebike seems good when it works but the customer service and being called a LIAR by staff is enough to cause a bad review. I don't get mad easily and I have ridden and fixed bikes for 50+ yrs. But being called a LIAR was to much Stay away if you buy one pray nothing fails
