The goal was to design a 3D-printable motor mount which is robust and strong enough to withstand large forces even during hard braking. The electric longboard has since replaced my bicycle as my main transportation device. As of March 2017, the electric longboard has covered over 150 km. I constantly dis- and reassemble the motor mount to clean the components and also to make sure that there are no hidden fractures. So far it is holding up and I will continue to monitor the mount during the entire test phase of 1 year.
