Send Superstrata your dimensions, riding style and preferences, and they’ll 3D print you a carbon fibre bike frame made to fit. Prefer a stiffer ride? A bike for commuting, or for touring? Superstrata claim to have over 500,000 possible combinations. There are two versions available: the traditional Terra bike and the Ion e-bike. The Ion has a sleek in-tube battery (no bulky black boxes in sight), takes two hours to charge and lasts for up to 88 kilometres.
