The world we designed our bike for has a lot of earthquakes, and the ground can split open at any moment. So we wanted a bike that can drive on the road normally and if the ground splits open the bike can ride inbetween the ground .Our final project came out well. We have faced multiple challenages while drawing a sketch of our bike, but once we've started working on the actual model things became easier. We desided  to have forward wheel drive to make driving and steering easy. We placed two small motors attacted to the front wheels which is the only difference from the back wheels. The arms of the bike are mobilized by cervos which allows them to spread out an the wheels rotate. We added a threaded rod through the arms on both sides to keep the bike stabble. Otherwise the arms will be stabble and could cause the cercos to weaken. One thing we could have done to make the project better is 3D print a body other then having a rectangular shape, yet the project itself was a success and something we are proud of.
