OK, so we got the Novara Safari my wife was interested in. Couldn't see one in person, ordering was the only way to get one. The fork has vertical drop-outs, so it looks like Novara didn't design the fork to be safer with disc brakes.
That said, what I am taking from most of the replies is that if the front quick-release is checked regularly then it shouldn't be a problem.
Would putting a zip tie or hose-clamp on the quick release further increase the safety? It wouldn't be able to loosen much if the lever is basically locked against the fork. Does this sound reasonable? Thanks
