A little more progress

I finished modeling the house for my character and I'm working on the design for his bike.  I'm kind of stuck on what I want it look like.  I was kinda thinking of just having a parachute type thing on the back of the bike or some kind of flying thing, but I want the flying part to break when it hits the ground and still be able to ride it.

                       

 

Some of them are upside down, sorry.  Any suggestions are appreciated
