I've seen your facebook post with the bike, and it looks like it is high poly, and has lots of useless loop cuts especially on parts that are so insignificant.
You can cut a lot of the rendering time if you remove the poly surplus and add lower res textures on parts that do not require as much details as the obvious bigger parts.
For example the chain, I hope you won't model a high poly detailed chain and instead be smarter and make a lowpoly version, if you want to go even faster, you can extrude a plane and just apply the texture of the chain with transparent background., haha, this won't look too good tho.
Do not add details by adding more geometry, instead, use Normal Maps, bump maps and stuff like that.
Also, do not add more geometry, loop cuts than needed, if the low poly does its job well, you don't need to add more polys just for the sake of it.
Here is a good example of a Low Poly bike that still looks awesome.
