The geometry of the eBig Seven and eBig Nine follows one very simple principle; as sporty as possible, as comfortable as necessary.
The addition of a motor makes this perfect for commuting to work without arriving bedraggled or feeling worried about being too tired to make it home. Alternatively, its mountain bike geometry, suspension fork, grippy tyres and powerful brakes offer the opportunity to venture further afield .
