My father has always been low vision but has recently become completely blind. He really would like to exercise but has had problems lately going out and getting lost. He's late 70s and has a hard time with anything digital. Does anyone have any recommendations for a treadmill that's easy to operate with a safety clip? Less buttons, more analog the better.

Find an. Older model with buttons honestly. And yes they can work a lot of it will take memorizing and stuff of that nature.

The stationary bike is good. I go to a gym with all bells and whistles on the treadmill, but just use the quick start button and toggle up or down the speed and incline. I believe they all have the safety clip. I would take him to a sporting goods store and let him at least him get the feel of it and the layout of the controls. You don't want to spend hundreds on a coat rack because he is uncomfortable with it. You can also see how much real estate the thing takes up in a room. If you go the stationary bike route, he should try that out also. Then compare prices on the internet, that stuff is expensive.

If a treadmill is still appealing, Landice and Sole make models with analogue buttons to adjust the settings that matter: start, stop, speed, and incline.

I have a Nordictrack X22i that I love to walk and jog on. The belt is very forgiving for bad knees far more give than any other treadmill I've been on. There are several speed buttons along the right hand side. I've put a bump dot on the three, six and nine mph buttons as well as on the start stop buttons.
You can also find manual treadmills that are not electrical that you just hop on and start walking. A quick search on Amazon for manual treadmill yielded results from the Sunny Health $169 manual treadmill to the $3k Assault Runner
