I'm just getting started on it, all this info is just what I'm expecting.

I am using the components of the T-Wreck to build the trike, but replacing the lead
acids with a lithium pack. The time consuming part will be the fabrication of the new
bracketry, and the spot welding of my lithium pack.

Check back for updates and eventually performance specs!
