The Alinker is designed to make walking easier and is best suited for flat and relatively flat areas. Going up and downhill is more challenging, as going uphill in a wheel chair or on a bike would be. It is hard to speak in general but some people will see slight hills as a good challenge to practice their muscles and gain strength and for other people slight hills might be too challenging.
The standard rear brake is adequate for everyday use and can be held when going down a slight sloping area in order not to speed up. When going down hills, you should not pick up speed, stay under 5Km/hr. (3MPH). The Alinker R-volution should not be used to race downhill for example. Suggested speed should not exceed 5km/hr, going down sloping areas suggested to go slower and stay safe and in control.
