for just $10 more you can get the

Edit: 1x7 may even be unrideable if you have any sort of hills in your off-road. And going through deep sand or sand also requires low gearing.
Where im at most of the bike/rec area paths are flat, one really wouldn't need more gearing. That said, these cheap options are solely recreational bikes, where the owners are never leaving such terrain
