there is also a kit i believe called a tricycle kit (a couple ladies in my area have these )its a frame that bolts on to the swing arm with a wheel on each side almost puts you in mind of training wheels thay seem to like them pretty well except doing the sharp turns threw the narrows (199)they have to slow down a bit more in the curves sense the wheels dont have a independent on each wheel ,plus the unit can be un bolted from the bike and ran as a reagular 2wheel motor cycle .they look kinda funny from behind with there 3 wheels at the back and one in the front but what the heck these older gals are in the wind ,its cheaper then the trike conversion kits and seems to be a good made unit .now if thats what they need to hold their bikes up then its all good
