At first I just wanted to make a sidecar. But the new LEGO motorbike isn't quite good for that. So I needed to build a bike, which turned out to be quite a challenge. The idea of using technic pieces like this is not mine. I found it while searching for other LEGO sidecars.
About this creation
The back of the sidecar. I just realized, that I forgot to make a photo of the front of the sidecar.
I think this side pic will do it.
The motor from the side. Yup, it's not minifig-compatible.
Bike without sidecar, so you can see both sides look exactly the same.
My pilot crashed his plane, and turned into a metalhead biker. He's looking for a cold beer right now.
