I needed to post my handle, brycer1968 made it for me, it’s a curved bar (to the right, I hold my handle with my left hand, mostly) with a delrin ball end. The handle fits into the existing KH handle mount on the seat. There are a few advantages to doing it this way as opposed to bar ends.
Much stronger, especially with torsional stability.
I can have different handles that fit into the system
The Delrin ball protects the end and also serves as a “nub” to rest my other hand on when I am on flats and cruising.
I can adjust the angle, how far out the bar extends, etc.
