Hi - I recently got A Certain Brand E-Bike that turned out to have several problems and I eventually returned. Online company, no nearby place to have it worked on, the whole process took months. I like the look of the Qualisports Dolphin and my only qualm is that it is also just online and I would have to send it back (or convince them to let me send it back) in the case of serious problems. Can anyone reassure me? I am not a frequent rider, but would like the e-bike for hills etc. The video review looked promising, esp. the larger wheels in terms of comfort despite lack of suspension. I also like that it's foldable (could fit in my sedan trunk) and that the battery is removeable. Thanks!
