Can You Ride Tandem?
I bought this seat for my bike, at the weekend. I bought it for Siam to sit on so that me Tyla and Siam can go out and spend some time together. Probably the wrong time of year to be going out a lot with winter coming on soon. We have been out 3 times this week already. It also gets me doing some exercise that I am need of doing. Siam seems to be enjoying going out on it.
