I haven't seen a rule saying you can't put two bike in the election, so i'll let you decide what to do with this second proposal.
My best bet would be to let them both compete and add the votes
But i honestly think that one is enough and that the ARC AS LT has more chances.
Here are the two allowed pics more in the readers bike section.
Good vote (i guess it wiil be starting soon).
