We are working through a similar exercise now. Our starting point is as follows:
TV with 1.25" receiver, 220# tongue weight limit
CI 550 with 2" receiver, 150# weight limit
2 bikes at 30# and 50#
Our current setup is a Bikewing Neo (manufacturer = Let's Go Aero), 1.25" hitch.
This rack is sturdy, lightweight and relatively inexpensive.
We mount it either on the TV (when CI isn't needed) or securely bolted atop the CI tongue (no propane tank).
It is easy to move (10 min) to move from one configuration to the other, once the bikes are off
We have some issues when traveling that are manageable, but not ideal:
1. Turning radius when towing is very slightly reduced, but not a real problem.
2. Exceeds recommended tongue weight for TV if bikes are fully loaded
in this case we move one of the bikes into the CI (ugh)
When the rack is mounted on the TV (with CI parked), there are two issues:
1. the TV hatch can't open unless the forward bike is removed (minor issue)
2. ground clearance isn't great - OK on flat roads but not in rougher/hillier terrain which risks damage to the bikes
We are looking for a solution in which we can bring everything conveniently without risking load limits or impacts on the bike.
Our focus has been on a sturdy bike carrier with good clearance and a 1.25" hitch. We are considering the current Kuat line, which is expensive.
The rack weights are of the order of 40-60#, so no problem for the TV but pushing the limit on the back of the CI.
Q1. To put the rack on the CI, it needs to mate to a 2" receiver. Does anyone have any experience with the use of adapters that bolt securely onto the 1.25" shank without shims (link
1.25 inch to 2 inch Adapter). I am against using simple adapters, for which any mechanical play that leads to bounce.
Q2. If the answer to Q1 is not satisfactory, what is involved in swapping out the CI receiver hardware for a 1.25" version? There are bolts on the receiver beam near the CI axle, underneath the galley, and possibly more is involved. Craig indicated to me that it was possible, but it may be a bigger job than I'm comfortable with.
Thanks in advance!
