Although I've considered upgrading my 2017 Lynx before, it has been such a great bike that I just never had until I saw the new Ram SS bike this week. It has a stepover height eight inches lower than the Lynx, making for an easier safer mount and dismount, especially for anyone with hip or knee issues.
Beyond that, the Ram SS is an upgrade from the Lynx in almost every other way as well. The frame is aluminum, rather than steel, which cuts about ten pounds from the overall weight - very helpful when wrestling it into a car. There is also a front suspension, an upgraded controller that now shows distance traveled and current speed, and allows five levels of assist rather than the previous three. The motor is now 750W at 48V, rather than the previous 500W at 36V. This means more horsepower when needs for the steepest inclines. Front and rear lights are included, and thankfully don't need separate batteries. The fenders and rear rack I'd added to my Lynx are standard on the Ram SS. Mine also came with a very nice handlebar cell phone holder that easily adjusted to safely hold my large iPhone, though sadly I did have to remove its removable wallet first.
One remaining option I recommend is a 15AH battery, rather than the standard 10.4AH. I'd already made the same upgrade to my Lynx, and have never run out of power in three years of heavy daily use.
Overall, an excellent top of the line folding bicycle. Highly recommended!
