Great piece of kit utterly disgraceful customer service. My kit requires one more part, not known at time of order and there is no way of contacting swytchbike. There is no customer service number. There is no interactive chat line. You can only follow a preset list of responses which eventually loop back to the start. There are no humans to contact. Does anyone have a telephone number or email which will go to a human? I have had my kit now for 4 weeks (took 6 months to get) and cannot do anything with it. Cannot even buy the part I want as an accessory because it isn’t listed as an accessory and I can’t talk to a human. Don’t waste your money. If this is the future of AI God help us !
