Having someone you love wanting to ride but unable to control the bike on their own should not mean they are left out. We have independent rider options, trikes for assisted rider and passenger bikes. An independent right might need a remote-control. An assisted rider can be helped with a rear steer, a side steering arm or by sharing the ride on a side-by-side. But if they can't pedal or won't pedal, how about a passenger bike option.
Having poor eyesight does not mean you have to forego riding. We have solutions for independent riding, for riding with someone assisting alongside or with a pilot and also a range of options where you enjoy the riding experience more passively.
