According to https://together.bunq.com/d/27058, the limit for a single contactless payment is 50 Euros in many European countries. And https://together.bunq.com/d/49784 tell us that the limit for cumulative contactless payments is 100 Euros before a PIN is required.
There are some other Together articles that reference a 25 (single)/50 (cumulative) limit https://together.bunq.com/d/6635 in one section, but state that the cumulative limit is actually at 150 Euros or 5 contactless payments in total regardless of height in another section. Maybe bunq needs to do some house-keeping in the help section.
However, in any case these are just the limits that are set by bunq. If a payment terminal sets its own lower limits (for example because it still enforces the previous lower limits), then you could still be out of luck. It could therefore be a good idea to also set up Apple Pay / Google Pay on your phone, so that you can always pay contactless like for example in the public toilet example provided above.
