I purchased a Sondor Step in January 2020. I received it in February 2020. The LCD screen would not register the battery, mph, etc. I called. They sent me a new LCD. It did not fix the problem. They then asked that I run the battery down. Said battery appeared fine and they would need to speak with colleagues and get back to me. They never did. The battery is not fine btw. Email after email, call after call they just sent out a new controller for me to install. It didn’t fix the problem. I emailed them. I called them. No response. I called sales they tried to send email on my behalf. After multiple emails asking that they pick up the bike, because it’s a lemon they finally sent new email for 15 minute tech appointment. Tech said he didn’t know what to do. We could drive bike to shop in Venice. We are South Orange County. We asked to speak to manager. Was told she was busy and would call us back. Waited a week no call. Set up another service call and asked what our options are he said “I’m not her boss, she is mine I don’t know when or if she will call you” He said “see if she calls” we said unacceptable. He said he’d see if she was available for phone call. She got on and said she could have someone service bike. I said when? Because it is now April 20th. I said it needs to be done this week. She said it could and she’d call me back. No call and called Grant this morning and no service appointment set up. I am extremely disappointed in SONDOR. I have been more than accommodating. I would not recommend to anyone. Still waiting and would like to ride my bike with my kids during this quarantine.
