Steering is power assisted but it still takes more input than a Venture, normally wouldn't be an issue but if your arms or shoulders have a weakening effect the difference will be noticed.
My wife had one for about 3 years and there was nothing wrong with it. Never any issues. she stopped riding out of fear (and weak shoulders). She had a close call on a ride that scared her pretty bad. The spyders do take a lot more shoulder input than a bike or trike.
