However, having thought about the matter a little more, here are a couple of points.
1. Many of the FuroSystems reviews are from those who have also submitted reviews for other companies. Fake reviews are generally from those who submit just a single review (either gushingly enthusiastic or harshly critical) and then vanish.
2. It's clear that FuroSystems asks its clients to submit Trustpilot reviews. Next to the number of green stars on a review there are the words "Verified order", and if one points one's mouse at that something comes up along the lines of, "Fred Smith was invited to write this review by FuroSystems." That doesn't mean that he was bribed to do so. Juicy Bikes was mentioned earlier and it was said that it didn't have many Trustpilot reviews. Indeed it doesn't, but it would seem that at least in the past it has asked some clients to write them:

3. I guess that FuroSystems places more importance on Trustpilot reviews than does Juicy Bikes, which is hardly surprising for a newish company that's trying to build a reputation.
4. I'm not sure of this, but I suspect that if a company wants to link to Trustpilot reviews on its website then it has to pay Trustpilot for the right to do so. FuroSystems obviously thinks that's worthwhile, whereas other companies may not. For example, Raleigh UK doesn't seem to have any Trustpilot reviews at all, but presumably it's sufficiently long-established to feel that it doesn't need them. On the other hand, even a well established business like Richer Sounds obviously does want Trustpilot reviews:

To sum up, FuroSystems gets Trustpilot reviews because it asks its customers to provide them, and that seems to be a common business practice and nothing sinister.
