Bike animation

Hi Daz people,
Just wasted a 12 hour render on an animation where by I thought I'd parented the bike and person only to find out it wasn't a smooth transition.
All choppy,bike moving leaving behind Genesis 8 then catching up again.
Bascially a mess..Wondering what I'm doing wrong?
Any help would be much appreciated

Hi.
My Advice is to create a Null and postion your figure on the bike /cycle etc.
Parent both the bike and the figure to the null and animated the null moving along.
this will keep them together as they ride /peddle along.
Hi Wolf,
Thanks for replying.
I'll give it a shot and see how go's.
I created a "group" and added them together,hit render so I'll soon see what mess I've created.
Looking forward to doing it the easy way.
Thanks again
