A while ago I put together 3 warbikes and did some small conversions. You can find that post here: Orks: Warbike Conversion made easy
I finally painted them and decided to put one up.
First of all these bikes didn't come with bases, not sure if that's normal. So I made a base out of WHF movement tray, which is also the basis for the side car.
Then did the tilt, a little ornamentation and voila.
Easy and fun, that how I like it.
