Whoever likes travelling by motorcycle , attracted by remote corners of our world, discovering areas where the term „road“ means nothing but a more or less prepared path at best, – he will most probably have had the wish for a motorcycle driven by both wheels – an all-wheel-drive motorcycle.  
At the latest when the heavily loaded motorbike got stuck in the muddy ground in a completely isolated area of the world.
The more it is astonishing that, until this day, none of the motorcycle companies have succeeded in developing an effective all-wheel-drive for motorcycles
A trip through the breath-taking landscapes of Iceland, which led to many findings when developing DT-A
The advantages are more than obvious :
    • essentially better traction off-road, or on unprepared routes
    • a more effective propulsion for rallye –bikes, especially when driving through desert areas
    • getting stuck on loose underground, for example on sand, mud, or snow, will be prevented to a large extent.
    • Obstacles can be passed much more easily, even with heavier, or fully loaded bikes.
    • With central electric power units, the recuperation ratio can be increased considerably ( cf. Gauss-Projekt TH Darmstadt).
The initial problems to be solved: Attempts to develop an appropriate all-wheel-drive have failed so far because
    • the amount of rotating / not suspended masses in the front-wheel was raised
    • the weight of the vehicle, was increased perceptively
    • it was always a compromise at the expense of handling and controllability
    • the transmission of power to the front wheel was limited.
    • the power transmission caused friction and a high loss of energy, so the additional drive was a drawback at high speed / high output
  That was how the DT-A came into being. No compromise
DT-A is small, light, and easily versatile. The rear view shows this most obviously. The front drive is hardly visible.
