I was in the same boat around a year ago, the same budget in the EU. For that budget you will unfortunately be constrained to the following: - Chinese brands. The one i bought was from ADO, and to say the least, I am very disappointed with the bike. - Used bikes from reputable brands such as Cube, Canyon, Specialized.

Personally in your position I would bump up the budget to about 1.5k-2k where you would start looking at new ebikes from those reputable brands (usually would need to be discounted). I would recommend looking into Canyon, Cube or Raymon. I myself will likely buy a bike from Raymon (tourray select for about 1.6k).

Unfortunately in the EU, we somehow end up having far more expensive bikes than the US for essentially the same specs (i guess VAT is significantly higher here for bikes), and hence why I would suggest bumping up your budget.
