What amount of climbing are they doing in that mileage & what modes do they use?
I’m getting the same average (large lad with lots of kit on a shimano unit), if I ride with fellow e-bikers (or by myself), but then we’re also doing loads more climbing, as no one minds them any more. My riding m8’s have Bosch units that give them a small increase in range but then my eco mode is a higher output than there’s apparently (not ridden with a or tried a spesh bike). If I ride with my very fit friend on his manual bike (I’ve spent 12 years watching him disappear into the distance) my range increases, so it’s not all cut and dried & I’m of the opinion that breaks to cool the motor probably would increase the range too & if I simply lost weight my range would increase.
I am disappointed by the range but at the same time a 2hr ride, is just that 2hrs of ‘quality’ riding, not 1hr 15min riding & 45minutes or try to keeping my lunch down or climb where I’m just grinding away to get to the top.
I got my e-bike discounted then a warranty swap & it was a bargain, but if I had a bottom less wallet, an e-bike with a 700wH battery would be my choice (stares longingly at the YT Decoy), but I know these damned things are expensive. What is worth bearing in mind is just forget about bling when buying, as 1lb weight saving in a 48lb bike is almost pointless, getting good (long or mid travel, as again short travel is pointless) suspension is the priority.
All said & done my e-bike has re-invigorating my mtb-ing experience & I do not regret going down this path
