>>8840750bikebots are inherently hard because the wheels can't really be broken up (except like, into two thinner wheels) and they take up like a quarter of the bike's silhouette.. Usually like this one, they cheat a little with smaller wheels and a bigger body.
I really wish we got more bike-combiners, like the bayformers one we nearly got (and they helped by having mono-wheel legs). two motorcycles together means four axles to make four limbs, and two seats to make two pauldrons (especially those cool seats you get on a crotch-rocket)
of course there's also the issue of the disguise being pretty terrible without a rider, but that gives you more excuse to keep human companions around.. and there was that one guy in Car Robots (i think?) who had a separate dummy rider that became part of him
