Having a non-removable battery is a big mistake IMHO, because that's a not insignificant chunk of the value of the bike.
Also, it's just a normal e-bike, limited to 25kmh, I wouldn't call that "quick" :)
If you want a real quick commuter then get one with a 45kmh limit, that is the point when it kind of stops being a bike and turns into a vehicle. But I think the target market is different in this case, I wouldn't leave a vehicle like that outside my property overnight, that means I need to have a garage or easy living room access. None of this matters for a simple commuter bike.
