Don't shoot me for posting this here, but this is the SiBi. A Si and Derbi DS50 mashup, it started as a frame and a dream.
The rack is from a Grillo and the side boxes are old Grande. The seat is actually from a Peugeot or something and held on using leftover hardware from installing my garage door.
Wheels and engine are DS50, handlebars are from a 2018 Tomos, and the forks are EBR, but Grande and needed some custom parts to fit.
