You know I prefer the smaller, and more simple style your tron bikes have to the official set. Would be awesome to see an entire grid/race track at this scale. Less is more when it comes to some builds.

fantastic! I admit I do not understand how you did them ...
Well, the key is the part #92690 I used to connect the wheels. And I used a brick 1x1 with studs on four sides (#4733) in the middle of the cycles. I think you can identify all the other part I used on the photos.
