Stefan nailed it. FX+2 you can pedal off motor with a bit of effort, although it rides well in PAS0 or Off.. it doesn't feel like a regular bike imo (or it feels like a heavy MTB). It can be done however and its kind of fun/challenging and its not tough to do so. The Vado SL feels like a normal bike and even a light normal bike somehow and pedals FAST off motor.. slight inclines, uphill etc. I've ridden the FX+2 uphill with no motor and it climbs well due to gearing but just takes a bit more effort due to frame weight. But yes the FX+2 is a great buy and even the DualSport if you dont need the rear rack and extra weight.Taking in the account the short distance of your commute, the FX+ 2 is certainly a good option!
He meant Vado SL felt like a normal, not heavy bike. Easier to pedal. Actually what happens with Vado SL past 25 km/h is your thighs feel heavier but pedalling is so easy I often overlook going past the speed limit! I only cannot pedal faster than 27 km/h.
