@ivani Ok, that's what I thought. Although you get better maneuverability than with a straight setup, the downside of rockering the wheels with smaller front and rear wheels is of course that you get less stability and grip to the surface. It also gets a bit "choppy" since the rocker is more "on and off" between the different positions. With our Flow Motion Technology you get a much smoother rocker movement and weight transfer for better feel, power transfer and roll on the wheels. If you use our Standard (straight) wheel setup and want more maneuverability we suggest our Advanced setup with a smaller front wheel in addition to our technology. You could of course also put a smaller rear wheel also (as in the banana setup) but my personal opinion is that you get too much movement and lack of stability. //Per
