@gingerw the Alinker is the only motility device I’ve purchased. I’m pretty familiar with walkers and I own canes and hiking sticks, but the Alinker offers something unique— providing support and stability while offering the opportunity to strengthen & build muscle and a chance to be mobile in a way that compares favorably to walking unaided. Since buying my Alinker, I have seen pictures of a 2-wheeled walking bike, but the Alinker seems to me a better fit as it allows me to simply sit without being concerned about balancing.
