Did almost 900km with it in 6 weeks. Keeps 40km/h at speed 3 and 26-30km/h at speed 2. Battery will surely allow you you to go 50-60 km. More mileage will depend on mode (speed) used. Full charge will take 9 hours._Rain/wet jump and hump resilient and strongly built overall._You should consider to place some additional lights to be more visible on the road as I did.
Really very good. It arrived in about 7 days from when I ordered it. Assembly was relatively easy, it was ready in an hour, and in another two or so it was charged. I've done about 15 kilometers, I don't know if it will go 100 on one charge, I'll see as I go. Anyway, it looks like it does what it says. It's powerful, I reached 43 km/h very comfortably, it shows comfort on the uphill. Negatives: its mirrors need changing, or tilting downwards, to open up the field of view, because what you see is your hands and not the rear movement. I am very satisfied, and I recommend it to all of you.
