I pretty much never use my ICE car anymore. I can get to
work in the same amount of time it takes to drive. My
normal cruising speed is about 23 MPH.

This bike is a work in progress. It is operational, but
it is not complete.

Work yet to be done:

install lithium batteries. (I ordered them express, but
they shipped them sea-mail anyway. Waiting. Still
waiting.)(update: finally arrived!!! Lithium is awesome.)

install baskets for carrying cargo.

upgrade controller to one with regenerative braking

install controller on battery bag with quick release wire
connectors so I can take battery and controller with me
when I lock it up.

install centerstand/dual kickstand (Update: Done. It's a
great addition)

install headlight (Update: Done! LED Headlight installed)

install taillight

install horn (Update: Done. Not very loud, so i'll
replace it later with something else)

Update 10/11/2011: I got the lithium batteries finally,
and they are great. I ordered a dc-dc converter, however
i haven't hooked it up yet. With a 12V circuit, i will be
able to install a car horn, and a bright headlight. Over
a thousand miles and i'm still riding it every day.
