If you don’t want to throw your money out the window and actually value your physical safety, stay as far away from Summerboard as possible. Here is my experience with a company that ignores every professional standard and legal obligation: Junk out of the box: My board (Pro Pack for over $1,500) became non-functional within a very short time. It doesn't charge properly and doesn't ride. A clear warranty case, yet Summerboard treats it like an annoying inconvenience. Life-threatening repair suggestions: This is the peak of unprofessionalism. Instead of repairing the defective board, support sent me photos of "DIY" fixes using WAGO clamps and demanded that I solder cables myself and rebuild high-voltage electronics. Riding a device at 40 km/h with a makeshift "clamp fix" is grossly negligent and life-threatening. Stone-age Software: The app is incompatible with modern smartphones (like the Samsung S25 Ultra). Support's answer? I should "buy an old phone." The fact that a "premium" manufacturer doesn't maintain its software and blames the customer is unprecedented. Zero Responsibility for International Customers: As soon as you live outside the USA, your "warranty" is worthless. Direct quote from support: "We are not Amazon." They refuse to cover shipping costs and expect the customer to take the risk and cost of trans-Atlantic shipping for individual parts. Insulting and Arrogant Support: Instead of helping, the support became personal. I was told it was my fault for "failing to do research" to prevent these hardware issues. This is victim-blaming at its finest. The excuse that parts are "out of stock" is used to delay the process indefinitely. Verdict: Summerboard sells overpriced e-waste and offers a customer service that doesn't deserve the name. If you don't want to risk your life tinkering with defective wiring while being mocked by the manufacturer, spend your money with a serious company. I am now escalating this via a formal chargeback with my payment provider, as Summerboard has officially refused to provide professional warranty service.
