OK, so please bear with this newbie as I figure things out... :-)  I am impressed with the Rad lineup but am driving myself crazy trying to decide which model to order. Most of my riding would be on bike paths (paved or dirt), but I would not necessarily rule out total off-road or sand travel. I am very comfortable on bikes, scooters, and motorcycles, but my challenge is I'm only 5'4". One of the Rad customer service folks counseled me that the RadRover Step Thru 1 would be too big for me and steered me to the smaller bikes. I'm not keen on the handlebars of the new RadRunner Plus, but it has other features that make it sound better than the RadMini. So, I'm hoping you all may have some thoughts to share with a vertically challenged (i.e. short) rider. Any help will be greatly appreciated!
