KingSong S22 Double Front Handle

Bottom handle functions as original.
Top handle can be used for seated riding.
Lower versions may fit better if you don't have a high seat like on the photos (but I've not tested them).

Handle is assembled from four pieces: two 25mm PVC pipes and two printed parts.
You need to cut the pipes as shown on the last picture.

You can apply insulating tape or something similar to the pipes for better grip.

This is the first version, I was pretty satisfied with it. Tell me if you need some modifications. I don't own S22 anymore, so I can't test it myself.
