I bought two Ep-2 Pro, one for me and one for my wife. We are very happy for choosing this model. It's super comfortable to ride, although not having a rear suspension, the fat tires do their job making the rides very enjoyable. The motor is incredible, allowing smooth accelerations. Mostly, I ride using the pedal-assist mode, using the level 1-3 it's enough for me because you can really feel the motor kicking in. Rarely used modes 4 and 5 that are really powerful. The twist throttle is a plus and the fact that it's connected to the selected pedal-assist level you are using makes it very secure (some bikes have all the power available when you use the throttle which can be dangerous).
We also bought the Engwe 17-liter bag to take on the rear rack. The bags are really good, with amazing quality!
Just a few words for Engwe customer service. They were amazing, always answering my questions and they made a big effort so I could receive the bikes in due time!
