Yes, thats right I own a Tas QBM-23N. I have it mounted on my SX-200 Pacific Mountain bike. What a treat this thing has really been. I first noticed it when I moved in this old house I got. The motor was mounted on an old bike that was all rusted. I took it off and mounted it on my Bike, of course after I got it running. Come to find out that the motor has very little miles or, hours. I will have some pics for you all soon. Does anyone know if there are diffrant size wheels, or whatever they are called, the little wheel that go's on the tire to make the bike move.
