This is a much better fit for exercise bikes than the other gel saddle covers I have tried (which seem to be designed for real bikes, with their generally smaller saddles). It will go on to my fairly large exercise bike saddle (John Lewis one - similar to a Bremshey) and also on a York cycle/rower relatively easily. Having said that, it is still not quite big enough - if you sit right back you kind of fall off the gel bit. And it is true that the gel is not super thick. But it is pretty comfortable, an improvement on the padding of the original - and (my big criterion) it is definitely an improvement over sitting on a saddle whose cover had split!
