I have an original Switch bike conversion kit, and everything is good, but I wanted to upgrade to a newer type battery, so I started an order in November of 2024, put in my credit card, but then changed my mind and never completed the order. My card was charged, and I told them to cancel the order on November 22 of 2024. I was told to cancel on the order page, but that option wasn't there. I sent them a screenshot showing this, but they kept saying the same thing. Finally, on January 6, 2025 I was told that I was getting a refund in 7-10 days. On January 22 I contacted them to ask why I didn't receive my refund yet, and they informed me that the order that I never completed, was on it's way, and I would have to refuse the order or send it back in 14 days to get the refund. There is no tracking number for the order, no phone for Switch bike, and emails accomplished nothing, eventually circling around and saying the same thing they started saying. So it is a great product, just be sure it's what you want before you order! I think it may take a year and a lot of work and frustration to actually get my money back
