Performance on the Trail
On the trail, the EP801 delivers a natural and smooth ride feel. The increased power output is evident, providing ample assistance on steep climbs and technical descents. The extended overrun feature ensures that riders can maintain momentum through challenging sections without the need for continuous pedaling. However, some riders have noted a slight metallic rattling noise during coasting, which, while not overly disruptive, is worth considering. (mbr.co.uk)
