I know the gas tank in front is popular, One of my Whizzers have the gas tank in the front like the Chinese engines do and it looks nice like many of the bikes on this forum.
In my case I just wanted to keep the simple bicycle feel. However, with the roar of the engine a lot of that is lost, but it still add up to a lot of enjoyment.
Yes, like your bike, my bikes get a lot of attention also and for me that's part of the fun. I have seen pictures of your neat bike and can see why it is popular.
