The model is based on the idea of using a Panel for the seat. It’s lower than the plate and allows to place minifigures inside the construction. Another idea is the back part of the speeder with a grey cheese slope to achieve the colors and shapes of the original. The stand is attached to the mixel joint, so the speeder can take dynamic poses.

The goals were to rich motorcycle-like position without detaching minifigures legs, and fit it in the correct scale and color schema.
The length of the speeder is 4,5 m according to Wookipedia, so ~3 clones’ heights.

There are already a lot of fantastic custom BARC speeders, and I took inspiration from some of them:
