I can't imagine a bike with only a normal sized toptube actually be strong enough to handle any type of riding that requires 180mm travel, like this bike has. Also the front wheel moves quite a bit backwards when the suspension in the fork compresses, making it sketchy due to increasing chances of flying over the bars. As far as I see this is nothing but a very fancy eye catcher. Amazing machine to look at and have a deep think about, but not something you'd seriously ride.
