Excellent and personally responsive customer service.
Part of what made my customer experience great is the quality product, for me the 2 different e-bikes I have ordered in the last 3 years; another is the very responsive and problem-solving customer service - I have been communicating with the same great CS person Emil whom I first reached over 3 years ago; and a third is Sixthreezero’s high degree of interest in informing the customer on all aspects of how to select the right bike for your riding experience, size and needs/wants, how to ride safely on the e-bike in particular, with videos of each e-bike they sell showing the particular features in action, critical measurements of things like maximum and minimum seat height to ground, distance of handlebar from seat, etc. I never realized how much difference not only for comfort but also for safety these things can make, especially on a motorized vehicle like an e-bike.
