Hello - finally upgrading to an ebike. sort of narrowed it down to these 2 but open to suggestions. there are many threads on this topic already i know and sorry. will be street and some light trail riding. i was leaning to the Espin but told that they are only class 2 and not upgradable anymore to 3.  the R1U is a 3.  anyone have feedback on this?  otherwise, aware of the difference is tires, fenders and gears(11-12 teeth).  thanks in advance!
