Hello all,

I am a 4th year mechanical engineering student at Bath University and am involved with a group project in which we are designing a FMX backflip support system such that someone with no riding experience can perform a perfect backflip, or alternatively someone training can learn the trick in complete safety. We have come up with a design that involves connecting a forked attachment arm to the bike as shown below:



I am pretty unfamiliar with bikes and therefore I would appreciate absolutely any advice on where exactly to attach the forks (the most structurally sound on the bike preferably) and how. Please bear in mind that the arm is forked to avoid the users legs. However to make the rotation realistic, the forks have to remain equidistant from the centre of mass of the bike and rider, so current location can be changed but only within reason.

Any advice would be a massive help so many thanks in advance for any contribution, any used will be acknowledged in our final technical report!
