Been a while since I've posted in this thread.
Sounds like my Sport's bottom bracket is creaking and I don't know if that can be fixed because I think it's sealed.
Other than that... still going strong. I'm spoiled by the advanced cadence sensor because after these few years I really had the gearing and PAS figured out. The Soltera is a torque sensor so it's a different style of biking.
Even though I got a lighter ebike, I still think I want a comfortable rider for casual rides and the R1U
Portola has features that the
Lectric XP 3.0 didn't have... and they have a blue lone ike my old Sport so it will be the spiritual replacement (but it folds instead).
If I were to replace the Sport with a like bike... as I said before, the R1U Turris is the closest match (and maybe the Cafe Cruiser).
Espin bikes seem overpriced compared to R1U now.
