BEFORE you buy an electric bike......
Recently purchased a Sparta ION, only wish I'd checked if they would provide a technical service manual first, as even for a "simple" real wheel puncture repair, the bike has to go back to a Sparta dealer for repair, AND unlike Holland, here in the UK this may involve a very long journey indeed. Unlike some e bike manufacturers, Sparta refuse to provide this information, so won't be buying a Sparta next time.
