You can find more information about the Whike at whike.com.
I had been interested in trying a linked-delta tandem for some time, and I've been curious about sail trikes even longer. So when a Whike turned up on Craigslist, we got it. It's been a lot of fun! We don't get enough wind for good sailing in Santa Rosa, but the tandem setup is pretty good.
