So your view is that the expected lifetime of the product is identical to your one year warranty? I think that's the sort of thing you're supposed to let your disappointed customers discover after they've purchased.
Or basic arithmetic. 30,000 miles in a year is about 3 x 30 mile trips per day, every day.
Even if you rode your 30 miles every day, that's more like 3 years and less like 1. I wouldn't be disappointed if I had to change my battery (which really should be considered a consumable) after nearly 3 years. None of my phones that cost this much or more have done as well. I would like to see a slightly longer warranty on such an expensive thing, but its not completely out there.
