Good foldable bike?

Dahon is quality built for smooth surface. Check ThorUsa.
I also have Montague that is mtn bike

 

I don't have any experience with the foldable bikes, but maybe rethink running.

I've always blasted running as too hard on my joints, and every time I tried, my lower back, knees, and left hip would kill me.

But, I tried again. I focused on doing stretches for a solid 10 minutes before running, and 5 minutes after, along with a dead hang.

I've been running 2 and a half months now, usually every other day, and bicycle at least a few miles on off days. Pain free for the most part

It's been a gamechanger for endurance.

But if you can't, the bicycle is certainly easier on the joints. Looks like @cuzzin it has you pointed in the right direction.

 

My doctor told me "No Running" and just brisk walking.

 

Dahon make a wide range of folding bikes and then there are the Brompton range of bikes, the Rolls Royce of folding bikes (with prices to match!)

The only issue I have with folding bikes is the wheel size, I understand they have to be small to fold effectively, but you lose the smooth ride and gyroscopic stability you have with a larger wheel size.

is there any way you could store a mountain bike on a rack behind your sleeper? Maybe with a small tarp to keep it out of the elements? Perhaps modify a truck bed style of bike rack?

 

I’d suggest buying whatever bike you fancy and a high quality bike bag. With QR axles or thru-axles, it’s pretty quick to break down a bike and throw it in a bag. Then, you have zero compromises, as far as the bike goes. When you’re home, you’ll still have a bike you can get out and do some enjoyable miles on.



With a folding bike, you’re still going to want a bike bag, to keep filth and drivetrain gunk off your stuff. When folded and bagged, they’re really not much more compact than a broken down, full-size bike, in a bag. Then, the riding experience is going to be compromised, every single mile you ride. Their advantage is for someone who lives/works in a high-rise and uses an elevator. They’re quick to fold, with no loose parts. Otherwise, I’m not sure they’re worth the compromises. But, if you feel it’s the way for you, Dahon offer the nicest models, for the money. And, they offer their own bike bag.

 

Ducnut, That's a perfect solution! Where did you find that bag?

 

You can find EVOC bags, anywhere online. They’re kind of an industry standard, in non-rigid bike bags.
