I did a lot of searching and ended up buying the Marz Z1 for $650 for a few reasons. It is a cheap upgrade from what I have, it is specced on the next level up ebike like mine, they have the grip damper which I loved on my old rhythm, are made stiffer than a normal 36 which is good for an ebike, if I don't like the feel then I can convert it to coil for a reasonable price later, and this one just had the uppers replaced and uncut so it was long enough for my frame and means all the insides are new and fresh.
