Here's a question. When I take my girl for a ride on the back of my bike it never works out as well as I'd like it to. For example. If she sits up too straight I find the weight distribution is so off that it's tough to control the bike in the first place especially at slow speeds. And when she holds on to me tightly I have much more control but its so much strain on me because I'm holding her and myself up with my arms. What are we doing wrong?
