I use the MX2 to commute on a daily basis (18km back & forth, 250m elevation). I ride in turbo mode, with light on as it's quite dark now. THis will drain a bit less than 50% of the battery.
So overall, I would say around 45km range in turbo mode
Even if the MX2 require very little maintenance (Carbon drive + NiVinci + Bosch performance line), I would recommend to find a dealer nearby. Going thru the different forums I have seen that some people had defective components to begin with (some Perfomance Line defective batteries or chargers...
Got my GRACE MX2 S-Pedelec a month ago.
A wonderfull bike for commuting !
just added a Cane Creek Thudbuster for more confort (had to drill a little hole for the rear light wire in the seatspot).
Nu Vinci + Carbon Drive + Bosch Performance drive is the ultimate combo.
No maintenance, great...
