With this upgrade you don't need to take off the bimini canvas even if you drive over 35MPH, while for pro model you must take off the canvas to avoid danger and damages in high speed driving or very windy weather. You just need to press the spring pin on each leg and slide the bimini to the shortest, and put the loose canvas in zippered pocket beneath the canopy.
