@cyclelicious Thanks for swinging by, @cyclelicious! This is indeed a Calfee frame, and belongs to our first customer. The battery is up in the bottle cage, on a similar quick connect system, no harnesses to plug/unplug, and fits a water bottle for when you want to go for a pure pedal :)
@MavEric6969 Hey Mav, we'll replace your existing rotor with our gear+rotor (180mm). If you don't currently have 180mm setup we'll use an adapter to get you up and running on our system.
