It's my first ebike so nothing to compare to, but I'm really enjoying it. I took the travel spacer off the MOD to increase stroke from 62.5 to 65, giving roughly 175mm rear travel, and fitted a 180mm air shaft to the 38. Lots of rocks where I am and the bb was super low, so no negative consequences and I can climb ridiculous things on it. Descending honestly feels so close to DH rigs I've had in the past, must be the chassis weight making it feel so planted along with the coil. I swapped the SLX brakes out for Dominion A4s 220/220 rotors, fitted DH casing tyres and a Tannus in the rear (after trashing a rim already).
No problems with the motor or headset so far at all, having done around 500km and over 20,000m climbing. The Acros headset is probably the worst single feature but I've been super careful when washing the bike and it lives indoors, so has dried out fully between rides even through the winter. I'm expecting it to be the first part to go though. I read in a forum someone recommending using Sugru to plug the port and fully seal around the cables, which I'll most likely try once the first bearing has bitten the dust.
