They don't even have listings in the archive for the Titanio, on the PT site. The Scorpion series was similar, but not made of Titanium, and much lower priced. I found a link to the Scorpions on the PT site, but they are not listed on the 'Ebike' page.
They were 2012 bikes, which is a very long time ago, given how things have changed. Prodeco is finally getting around to mid-drives, which has to be a big part of the future. They don't seem to have anything for S-Pedelec, as well.
Sometimes I think Prodeco wanted to start building higher margin bikes just at the time the direct Chinese stuff opened up, like the Crowdfund bikes. They are going with the Bafang mid-drive, the integrated frame version. I think that would be a better deal, but now there is a $2500 Haibike.
