I would buy a 45km/h ebike again in a heartbeat. The slower ebike has a better range, but it supports you less long and your travel time is longer (in my case 17 instead of 30min). Car drivers can always overtake you, at higher speed they need more distance. In my opinion, a rearview mirror should be attached to every bike for commuting. You will notice quieter e-cars or fast approaching racing machines much earlier and can take actions.
