Gravedigger----It just slows you down a little. But it's good fun, the kids love it because so many people talk to them while they are in it.
*Just make sure to give your feet room to pedal, and front tire room to turn, other than that, it's just fun trying to figure out how to connect it and all that stuff. The thing I found out that would help you is...... to mount the sidehack wheel just behind the center point of the main bikes wheelset. To far ahead and it pushes around corners and to far back it is tippy in the corners. And mount it on the righthand side. I put this one on the left to keep my little guys finger away from the chain. The right works mucho better.
Have fun!!!
