I could not see the linked picture, but it sounds similar to the cranks on the Thebis trike. IIRC, the Thebis was a RWD and rear-wheel steered delta trike. Reports from owners were that the front wheel was really difficult to remove for changing a tire because of the hub cranks. ---Hillel ============================================================ This is the Python Mailinglist at freelists.org Listmaster: Juergen Mages jmages@xxxxxx ============================================================
