Cabling 1

I've got to look at  some other trikes to see how they are doing their cabling.  I'm kind of stymied at the moment.  I put on one cable to the front shifter.  So I now have 3 gears up front.  But still only one in the back.  And no brakes.

Here's the one cable for the front shifter.

Here's the shift lever ... and the brake lever below it.

I did ride it up and down the street a couple of times while changing the gears up front.  Got some pretty good speed.  Particularly since I can only use the smallest gear in the back.
