K see ya later tater..

Oh, clarification - I have BIG BEN'S on my 29er. They're EXCELLENT!!!

Sounds like fun. I've developed an interest in those recently, though I have no mountain bike. Are single tracks doable with a folding bike and fat tires, "lack of comfort stemming from lack of suspension" aside?

I'd recommend a Montague foldie for trails and rough stuff. I had a Xootr Swift, and I did some light bike path riding here in NY. Heavier riding I'd have used my 29er for. Most folders aren't up to the task (except for a Montague).

Aren't up to the task due to lack of strength of the frame (ie, frame can be damaged), or because the wheels are too small / tires too thin to be comfortable?

The hinge. It's usually the weak spot. I'd recommend NOT doing the rough stuff on most folders.

OK. The fork is 2.75 inches wide.
Took two measurements from the rim, not sure which one is relevant:

The inner tube is a Joe's No-Flats' 1.75"-2.15", so I won't have to change it in the front wheel. When it's time to replace the tires, I'll replace the inner tube of the rear wheel with the same one as in the front wheel.

Go get the Schwalbe's ASAP,... You're good to go!!! :thumb:

There are many levels of single track, trails are designated by color,

Green is easy, mostly level, ok for mom and the kids,,just roots, small rocks and tight turns through the tree's, handlebars making it with inches to spare.

Blue Is Intermedeate, 6,8,10 foot drops mostly 45 degrees or so up or down. chances to 'Get Air',,
Skills often used, Bunny Hops, Manuals, picking up the rear end with the front brake to pop around a corner, banked turns, switch backs,,etc..

Black Diamond trails,, Almost vertical drop in's, often 10,20 40 70 feet very close to straight down. Only chance to brake is In the G-out at the bottom.
Speed near 30 mph, Rock Gardens, basket ball size boulders,, larger.
TRUE Trail bikes only here boyz...,I ride very few Black diamond trails as I cannot afford to be off work to heal broken collar bones or
wrists, ribs, etc..

Double black Diamond trails,,, I'm not some young fool who thinks he's gonna live forever. Adrenalin junkies live and break necks here..


These folders we ride,,GREEN only or you will destroy the bike...

My Light duty trail bike,,really a Cross country Full squish trail bike:

Oh the girl you ask ?
No Idea how she got in here :P

Thanks for the information. I wonder if in my country trails are color coded like you said.

BMX tires are 20".

I have one question is worth paying extra to puncture protection or not?
The price of the tire with protection is almost double.
Think about 20" 2.15.

Holy zombie thread Batman, but...

It depends. Is it worth it to you? Are you riding in areas with lots of broken glass/sharp metal objects/other things that will shred your tires, or are you mostly riding on clean pavement around a university campus or to the shops? Do you have a means of getting home (or to a bike shop) if you have a puncture, or are you likely to be stuck on the side of the road, miles away from the closest town? Are new tubes/tires for the bike easily accessible in your area, or do you need to wait 2 (or more) days for shipping from an online retailer?

If a puncture is going to leave you stranded or severely limit your daily activities, then puncture protection is definitely worth it. I've run both Schwalbe Marathon Plus tires and additional puncture-resistant liners inside the tires for situations like that, as the relatively minor cost increase (maybe $100 CAD overall) was well worth the reduced risk of getting a flat. However, I'm going to throw some inexpensive Primo Comets ($5 each at a clearance event at my LBS) onto my folder while I decide what tire width I want to go with, as getting a puncture won't seriously limit me (the bike is more for enjoyment than a steady mode of transportation).

The other thing to consider is whether you can afford to replace the tubes (and/or tires) if you do get a puncture; if tubes are going to run you $10 or more, and you need to get someone to replace them for you, then you may end up spending more in the long run by saving money on the tires if you ride in an area where you're likely to get a flat.

What bike shop has primo comets for $5?

Roads usually are not bad but often riding on gravel - like on mountains roads.
More interesting me durability.

I picked them up at a tent sale at my LBS; I have two that are 20x1.125 and one that's a 20x1.375 with kevlar and a reflective strip on both sides. It sounded like they were just sitting in the shop for a while and they wanted to get rid of them. As far as I know, Primo is a decent brand, so I just bought them in order to try thinner tires on my folder (I'm currently running 20x2.00, but I don't have enough space between my brake pads to actually remove the wheels without either deflating the tires or removing the brake pads). I'm actually planning on going with Schwalbe Marathon or Marathon Plus once I actually figure out what size tire I want.
