Whose EP8(on the market since september 2020 I think) has reached a lifespan of over 7500 kilometer? What's the starting date? Please only reply if you managed to ride over 7500 km. What's your riding style and terrrain? Riding style eg : eco+high rpm, shifting like on a non Ebike or always boost and low rpm and not shifing a lot? Mostly flat, 50/50 uphill downhill, only downhill and big jumps? Dry or wet climate? How did you clean your bike and how often? 25 (Europe), 30 km (US) or deristricted max speed? Only road, only mtb or mix? I did 7500km without problems on a full-suspension tandem with 180kg system weight. since januari 1 2021. Mostly eco and spinning 85 to 105 rpm. Boost to reach the end of very steep climbs. I shift just line on a non-ebike using 11 speed DI2. 80% offroad, 40% flat, 20% climbing and 20% descending. 20 % onroad often over 25km/hour without assistance. Only 10 wet rides. Waxed chains. Clean with brush and water maybe 10 times a year. No big jumps, but the cranks often have contact with the ground. Can take 2 630 batteries. Batteries still ok. Flat rides up to 120km. When climbing max 1500 altimeters and 60km. We do long rides. Each batterie was charged around 55 times. Start without assist. Tyres with good rolling resistance 2.6 and 2.4.
