My first electric build was mostly just a retrofit of an existing functional bike, so this second time around I wanted to start with a frame and source all of the components from scratch. I got a good deal on a used 2007 Orbea OIZ soft-tail on eBay, which is one of the 'full-suspension' frames I was targeting that maximized triangle area. The aluminum construction is impressively lightweight, and has a robust (so-far) carbon fiber flexible rear frame member supported by a Fox RP-23.
From there I just selected and integrated a variety of new and used components such as the 14S triangle pack, Adaptto controller, 3D printed brackets/mounts (Ultimaker 2 ftw), beefy disc brakes from Hope, and assorted downhill parts. The human-drive is a single speed - I grabbed the largest front sprocket I could find (48T) that would fit with the Raceface crank arms. Ghost pedaling is fun but sometimes it's nice to actually be able to stay in sync with the system at higher speeds.
Overall the ride is butter smooth! The dual-crown front fork soaks up the bumps and the Adaptto makes the whole beast whisper quiet. With the 26" hookworms and the H40 torque motor top cruising speed is about 27mph which is not too shabby. Now to start planning the third build...
