Note too that cyclocross bikes are heavier than road bikes because they have to take a beating (although not the beating that mountain bikes do) so a motor assist would not be that large a weight burden in a cross bike. The Vivax Assist only weighs 1.8kg (including battery) and comes in versions where the battery is contained in a seat bag or in a water bottle. And yes, the motor is in the seat tube.
