Need help buying an ebike

I want to buy an ebike for my commute to work (13 km per way) but ebikes are expensive as hell. I found this website that sells refurbished ebikes with pretty good reviews. The bike that I am eyeing is in the link below

The bike itself has less than 5 km use so seems to be in pretty good shape. Also there is 1 year warranty from the website. The motor is Bosch which is a pretty common one, I believe, so parts should be possible to find. I live in Amsterdam so there are a bunch of bike repair shops around the area.

Do you have any tips for buying a refurbished ebike online? Can you recommend or is it better to buy a new one from a shop around my area.
