Working on getting the design of the spine. I tend to build a 1/8" aluminum spine in the triangle area to mount the batteries and electronics. On this project I think I will cover the triangle area with a composite shell.

The eCortina is a strong, powerful and reliable electric bicycle. I created the bike over about 3 months in early 2011 with Earth Day in Oxnard as my deadline.

The eCortina electric bike at the Oxnard Earth Day 2011. The electric bicycle is running and complete but there are a few issues remaining, like black anodizing some of the parts, and final adjustment of the torque-limiter clutch.

This is the original eCortina, the v1 version. My first electric bicycle. The motor is much smaller, the batteries are in a pack behind the seat post and over the rear wheel, and this first electric bike project had a very different drive system concept.

The Rocky Mountain RM7 as conceived is an electric moto vehicle - still in progress - waiting for controllers to become rock solid with starting from a complete stop. Currently small light-weight controllers are not able to do this effectively and survive.
