It's called the Tarus 2x2. It weighs about 110 lbs, has a 2 stroke engine, and has a top speed of about 40 mph. It's not in production yet, but the blueprints/specs sheet can be bought for about $37 (they'll be in Russian). The production bike will cost about $1000 USD in Russia, probably more in the US.
Rokon 2wd / Tote Goat etc ... have been around for years FWIW.
The old vintage Rocons were the first thing that came to my mind as well...Didn't know they were still made.Which in turn reminded me of the old Argos 6 wheeler...Just checked... they are still around as well! http://argoatv.com/
