After having installed the FWD (Front Wheel Drive) transmission on my M5 bike I was able to do some tests and the result was encouraging.
So it was possible to start the build of the new tilting mechanism.
Unfortunately it was not possible to use exactly the same I used for the Raptobike.
In fact the frame width in the rear on the Raptobike is 100mm, while for the M5 is 130mm.
This means that although the mechanism is the same, the width of both arms has to be 30mm greater.
Here we can see some test of the positioning of the mechanism using two wider aluminium supports (40mm instead of 25mm).
An additional challenge is the fact that both rear arms are really very close to the bike frame, so additional spacing has to be provided for them to freely rotate.
In the pictures here below we can see the new tilting trike with the rear mechanism installed, together with the electrical parts (hub motor, controller and 48V battery)
Initial tests of the trike with the hub motor have been really good: the bike handles well and it is extremely stable!
The next steps are going to be the following:
- build the 3 support structures for the solar panels: one in the front, one in the center and one in the back.
- build the rotating mechanisms to allow the solar panels to tilt around the main axle
- build the frame to keep both solar panels (150W each, size 1070x800mm) together
