It'll be awesome once he's tall enough to use the bike with you. Enjoy the bikes sir, and realize that I'd be more than willing to take one should you ever need the space.
If you're interested, I could likely get you a free trip here to Florida for Otronicon if you're willing to drag one of the bikes along so they could showcase it.
lol, I couldnt imagine driving to Florida from here, especially in something thats big enough to haul one of these along with me. Googlemaps says it would be around 57 hours of straight driving.
You would have to crate the bike and fly down - I wouldn't expect you to drive most of the way across a continent.
