The San Franciscan maker of this Lifan powered bike liked the SMBR facebook page.

Look at the angle of the motor.

Looking at that picture.......makes my eyes hurt. Perhaps it will look different when you actually build it. That being said, some bikes have a lot more function than form, and when you really boil it down, whats more important? If the engine will perform to your needs and you can make the bike safe and reliable, go for it. Just dont show me any pictures of it
