It's a 2017, just after the hitch option was phased out. And now the tow package with the hitch receiver, tow bar, etc. is $1250. That plus the cost of a hitch mount bike rack comes to more than I'd like to spend to carry bikes. The falcon doors make a roof rack impossible, and I can't find a trunk mount bike rack that fits the X. Tesla won't sell the hitch receiver alone and they don't recommend putting in an aftermarket one. Which doesn't matter, because I can't find a company that makes a hitch receiver compatible with the X. Do the venn circles of Model X owners and bike riders just not overlap, so no one else has noticed it's not possible to carry bikes on an X? Anyone have any thoughts on this? Thanks in advance.
