Wie sieht's bei starrer Achse mit der Kurvenfähigkeit aus? Oder hast Du Freilauflager vorgesehen?

diese frage hat großes kopfzerbrechen bereitet. es ist ein zusatzaufwand nötig. zur zeit finde ich einen naben-motor im hinterrad am sinnvollsten in verbindung mit kleinen autobatterien, das könnte in engen kurven die reibung an den vorderrädern, ohne daß zusatzkräfte an den pedalen entstehen, überwinden. mit 2 x 40 Ah könnte man auch bei frost im winter locker den durchschnittlichen weg zu arbeit hin und zurück elektrisch unterstützen und wohl auch noch den innenraum frostfrei halten durch eine elektrische heizung.


this question caused a big headache. an additional effort is necessary. at the moment i think a hub motor in the rear wheel makes the most sense in connection with small car batteries, that could overcome the friction on the front wheels in tight bends without creating additional forces on the pedals. With 2 x 40 Ah, you could easily support the average way to and from work even when it is frosty in winter and probably also keep the interior frost-free with electric heating.

You could install a simple differential. The required bevel gears may be recovered from old angle grinders.
