How to test the endurance of a frame?

Hello everyone,

I hope I am posting in the right place.

So here we go:
I am planning on throwing a challenge to create a bamboo frame for a unicycle, but to declare a winner I shall test some endurance criteria.
The frame should be able to withstand this kind of tension:

The problem is that I don't know which tests I can set up to try the frames endurance repeatedly and reliably.


Do you think there is any low-tech test I can make to test this?


Thanks a lot in advance,
Jaime

Determine the forces and force vectors that are applied to the unicycle. Determine the nu,ber of test cycles required to simulate the desired life cycle.

Either by simulation, physical testing or both proceed.
