There was a 406 wheel Moulton - Pashley APB that may have been a good off pavement bike..

Bikes: Many Downtube Folders :)

I don't think any 20" wheel folder is made for off roading. The problem is while hitting an obstacle ( or a hole ) a small wheel bike can throw the rider off. Therefore the rider has to learn to move their weight behind the saddle when necessary.

Not trying to toot my own horn, but it will be hard to get a better off road 20" bike than the 9FS. However I do like the Airnimal, not so sure about the BF in the trails.

Thanks,
Yan

Alex Moulton bikes don't fold, but many models are demountable (they have take-apart frames).

A Pashley APB was ridden end-to-end on the Adventure Cycling Great Divide Mountain Bike Route. That model was upgraded some years ago to the currently available Moulton TSR, a veteran of many Third World tours.

The Great Divide, while not a typical road tour, is less than 3℅ singletrack. The vast majority is dirt and gravel roads. Still an impressive feat, but not quite "off-road" either.

Are there folders that can be ridden off-road? Yeah, there's probably a few, but it's like using a really nice knife as a screwdriver. It may work, but you're gonna destroy that knife.

There are folders built specifically for off-road use, like this one:



But like you said, it's like using a nice knife as a screwdriver. When hitting the trails, I'd just hop onto my Stumpjumper FSR.

There is no question about the Montague being quite useable as a mountain bike. Their frames are bomb proof.

their warranty---quoted from their website.

"LIFETIME – Frames for the lifetime of the original owner (excluding forks)."

Maybe it is worth looking at the tread-title and the OP's question again. There's probably no doubt that "classic MTB-sizes" have clear advantages in some situations off-road. I thinks the OP knows this, too. But he explicitely asked for the "best off road 20" folder".
In my eyes this still is the Airnimal Rhino (at least of the bikes that I know). BFs are pretty robust but lack suspension (which is a huge tradeoff offroad). Plus the long stem porbably is a disadvantage when seriously off roading. Moultons may be able to do a fair bit of off roading but they are clearly not built for that purpose and it would be mistreatment. Plus the suspension is not designed for off-road use (far too little travel). The Jetstream may be able to do the job to a degree but with the risk of damage. Plus Dahon themselves say it is a road bike that should not be used off road. And the Downtube (the only one in the list I never saw) looks like a proper bike, but also with limited abilities (or on-purpose-design for off roading) in comparison to the Airnimal. Plus it has a hinge on the main frame which for me personally would be a bit of an issue for an off roader. The Airnimal is built like a tank, well a small tank - in fact like a higher level MTB, just with smaller wheels. Therefor I'd trust it more offroad than the others. No shame on the Downtube though - just by looking at the different price level of the two bikes you can easily see where parts of the difference may come from.

Regarding 20" off road in general one should keep in mind that there is BMX and that there is bike trial. Both done with 20"ers. So, depending on the terrain, 20" may be a disadvantage or even an advantage. No doubt there are situations where the rider needs to have more skills than with a bigger wheeled bike - but I think the OP is aware of this. He doesn't look for the best off roader but for the best 20" off roader.

Did you read the page of the guy who uses a Jetstream for that kind of stuff that I liked to earlier in this thread?

Did you try YOURSELF off roading with a 20" bike that was built for that purpose? Or for that matter off roading at all? And what level of off-roading or single trailing are we talking about? You may refer to STS: Home odr https://en.wikipedia.org/wiki/CTC_off-road_trail_grades

I used to do a fair bit of mountain-biking in the alps, in Italy and in the German forests. From my memory over the years there were not many situations (if any) that would not have been possible with i.e. a Rhino. As often in life technique beats size most of the time...

I looked at the Rhino before I bought the Jetstream, it's a really nice bike but seriously expensive then, and more so now. Check out the folding mechanism first, as folding / unfolding is not something you would want to be doing too often with this (Rhino) bike.

Fully agreed, especially regarding the fold. Not a bike to hop in and off the subway. Regarding the price: Yes it is expensive. But when you look what a upper level MTB from a smaller company (as in "not a mass product") costs you could easily spend more on that (and many people do). From experience a folder is always a price step up from a non-folding equivalent. Well, here you go. Plus it is kind of a unicorn - I do not know any other folder that is really built for that purpose and on that quality level, so there's not much choice anyway. Airnimals are not cheap but very decent bikes.

Re;#35.. Nah, but NB off road bike wheels have trended to get bigger 26>27.5>29, rather than smaller..

I can use my Bike Friday pocket Llama & can continue riding on gravel roads after coming to the end of the paved portion.

not into driving to trail heads to bike single track , but help yourself.

Good point! When it comes time to purchase, I might actually do that.

It's surprising how few folding off road bikes there are. I've even expanded my search to folding cross bikes, which I guess could include many standard 20" models, and there's still not a lot out there. I think maybe it's just because of the US market. I see a ton of stuff coming out of Japan and Europe.

I also saw a folding 20" electric fat bike a few weeks back. Anyone ever see one without the motor and battery?
