2-wheeled Fat Boy..... the same bike I triked in '06, and I loved it both ways .
I chose to add a trike kit after loving riding on two wheels for 20 years just because I am so petite that I didn't dare go out on my own with the Fat Boy because of difficulty maneuvering in gravelly parking lots, uneven or sloped roads at stop lights, etc. When you firmly plant your feet (toes) but don't have the reach to do more than that unless the surface is perfectly level and smooth...... Well, let's just say it sure is wonderful to not have to worry about holding the big ol' bike up, and I love being free to run errands on it or take a longer ride without waiting for Mike to get home and go with me.
