I got the below from Mike
"Yan from Downtube has kindly alerted me to this forum thread (thanks, Yan). Yes, we are still very much alive and active. The Burke 20 is in production now. The frames are being made in Chattanooga, TN, by Lynskey Performance. David Lynskey (see photo), who founded and built the first Litespeed bicycles, is personally taking charge of production. We have taken delivery of the first batch of frames and they look amazing. We are currently working with suppliers to get full bikes ready for sale through dealers, probably in the 1st or 2nd quarter of 2017.
We have been receiving quite a lot of interest in the bikes, and we have exhibited them at Interbike 2015 and 2016, and also an airline-legal electric model of the Burke20 at the recent Consumer Electronics Show 2017. We hope to announce the schedule of availability and pricing soon, when we are sure the bikes are fully ready. We apologize for not blowing our trumpet too much for the moment.
