Hitch mounted Motorcycle - Scooter carriers

[Ken H.]

Hmmm...I'm not so sure about that "...back axle...fulcrum...". More
accurately, I think, the "rear axleS" act as a fulcrum. That is with the
OEM air bag distributing load between the center and rear wheels, causing
the actual "fulcrum" to lie at the bogie. With my 4-bag, or a Quad bag
suspension, the fulcrum would move aft from the bogie toward the rear as
the down force increased.

At least that's how it seems to me off the top of my head at this time of
night.

​Which is approximately what an "equalizer hitch" provides. You just need
to incorporate another wheel aft of the added load to act as the new
fulcrum.

Given all this load problem, please tell this non-cyclist why you don't
just use a "cradle" in the receiver for the cycle's front wheel and let the
cycle's rear wheel tag along on the ground bearing most of the weight. I
know such devices exist, I just don't know the pros and cons of them.

The cons are a few.
1. Try backing up one of those when you can not see it.
2. Wear and tear on the motorcycle tire and drive train.
3. It gets filthy with road dirt and debris.

The other con is the angle of the bike steering stem does not match the swing angle of the rear of the RV, so sometimes it will slide the rear tire
sideways instead of pivot at the stem.

Hi Rob, any chance you have a few photos of your set up?
Thanks for the response,
Mike

Hmm...I don't think I'll use one of those when I take up cycling. (Which
ain't gonna happen until after SHE's gone!)

Ken, Ken, Ken......... Have you forgotten that the one who goes last has
to dispose of
all the "stuff". Three or four rollback dumpster containers would be
expensive and
a lot of work to fill. Go first and get the last laugh. LOL

Oh, that's definitely my plan! Which makes my cycling days likely to be
rather limited.
