13b twin turbo rotary. the bike engine is a dummy. jackshaft driving the staggered "back wheels" with a total of three cv shafts. the front wheel is "a arm-ed" off the chassis like a side hack racing kit. (looks like it is floating up there). trans is an automatic vw product.there is ample room for one passenger and possibly a small dog in the hack. absolutley mental.
