I like the renderings, but if I can be nitpicking a bit thereās one thing that bothers me.
Shouldnāt the stand for the back wheel be facing the other way? Looks like it would be a bit problematic to put the bike down when the āhandleā of the stand is pointing in underneath the bike 
Smart, didnāt notice it.
I like the render but I think the worn tires expect me a bit that other parts would also seem a bit less smooth/new. I know the rest of the bike is not making contact to the tarmac (I hope) but rest of the parts make it really look like a render.
This was also a thing that caught my eye, I think both are same material in reality but they look really different. I think those parts would also greatly benefit from a tiny round edge so you get the edges to reflect a bit of light (what an infinitely sharp corner canāt do).
Thanks Oscar for the feedback was having some issues with a few bits and need to get back to fix it as most I was happy with it but some I struggledā¦engine wouldnt split for me with objects or surfaces which was unusual so think I will go into Solidworks and try and fix it there not had much time as busy like crazy!
Oh meant to say yes stand depends believe it or not but will swith it and see what you think
What will really help is my glasses as I didnt realise my glasses were way out of spec so had to get some new ones and some PC ones wish now really help and even more so with a new 4k monitor so fingers crossed I wont be missing basic things that came naturual beforeš
Haha saves you a headache as well maybe 
What I often do to prevent having to split things in KeyShot is to give the model I create different colour on different parts so they will be different materials in KS anyway. Not sure how Solidworks does materials but basically I do it only so things get separated after I load them since KS will divide all objects by material.
Yes I usually just give everything a different colour like most whoād use a traditional CAD package as it makes life much easierā¦my new specās have made thingās much betterš
