Saw someone riding one of these huge tire bikes around. The pics do not do it justice. OMG it's HUGE!
Oh my god, it's HUGE!

I use a 1989 model Stump Jumper...I've used it on playa the last 8 years and all the years before. I spend at least an hour cleaning it up when I get home. It's still got the original hardware. Yeah, it shows wear and tear, but with consistent care and maintenance, it's not destroyed. Oh yeah...I leave my primary mountain bike at home

And heavy.
I just finished drilling out the front rim, 1.5" holes between spokes with two 1" holes by the valve stem hole. This is to let retro-reflective tape show through in place of rim-tape, but it shaved 203g off. By also going with a 120 tpi skinny Larry tire (3.7" instead of the 4" stock Beast tire) and a down-hill tube, the total weight reduced on that one wheel is 2026g, or ~4.5 lbs., leaving the front wheel weighing in at 3588g, or ~7.9 lbs.. After I grease that hub, it will be interesting to see how it rolls with the 100mm rim spreading the skinny Larry.

What about other options out there besides Surly?


Be aware the green bikes are NOT all the same.
A lot of inconsistency.
I would not take a green bike out there.

There's many more tires from others available now. Seems more every few months.
I already have the Surlys.

Like the tires, seems there's more available every month or so.
There's the Mongoose Beast starting at $200 plus fixes and upgrades, then Sun Crushers ~$600, then Mountain Fat Bikes from ~1,200 and up.

Thanks.

I recall the front surly kit was $350, could be adapted to a lot of other bikes.
Sounds like some of them are higher than surly now.

Thought of adding 29" rims to my bike.
I'll never get 4" in the rear rim, but could change the front fork.

I rode a surly on the playa in 2007 for a few minutes.
First one I'd ever seen.

Gyre, Ive got one of the Beasts and even though its heavy its great to ride with a few mods.
I freewheeled the coaster and added front and rear brakes. Also changed the rear cog from a 18T to a 22T and put a longer chain on.

Go with a beater bike but maintain it before you hit the playa. The real threat to your bike on the playa is Ali Baba and the 40 bike theives that come to Burning man. I know that BM.org says no bike is stolen unless the lock has been cut and no bike is considered lost until the event is over. Where I come from if you take something that's not yours its stealing plain and simple. Maybe we should go back to the justice of the old west. In that time when you stole a mans transportation it was a hanging offense.

No it won't. It may get into bearings with poor seals or have an effect if a bare steel part is left in a damp environment for a year untouched, but it won't destroy anything.

The bike is more for my sister to ride and she didnt want the coaster brake.
It was easy to do....take out original spring and brake shoes....add longer spring and 1 washer. All done!

The coaster brake works fine on flat, open spaces...so don't think that you HAVE to do it for the playa. Better brakes would be a good idea if you wanted to ride it someplace with hills.

Even with the 5 mph rules, I found that having a bike with good front & back brakes kept me from injuring people who stepped out without looking.
Given the extra distance required with my Beast with coaster brakes, I'll have to take extra care on the playa to give extra room or stop and wait where there won't be enough distance for the coaster brake to do the job.

^ That and whats the first thing you think of doing when someone steps in front of you?
Step off the pedals.
With coasters you need both feet on the pedals to pedal back to stop.

I had to get some canti brake adapters for the beast to make them work. Kinda spendy but, oh well....whadaya do?

I took a new Micargi cruiser last year and it worked out well. Gave it a good wash and tune up right after getting back from the burn and still have had no issues with it. The year prior I took a mountain bike that I had purchased from craigslist and did the mistake of not making sure it was comfortable on long rides. It was such a pain to get around, never again. Make sure your seat and handlebars are comfy! This is key!

For Mongoose Beast.

I finally got around to riding with the Surly Larry 3.7" tire onto the stock Beast rim (drilled out) for the front wheel. Where the Surly Endo 3.8" was so much better riding, rolling and steering than the stock tire, with this setup, the Larry shows the same amount of improvement over the Endo. OMG, the steering and rolling issues are gone. And this is at 8 PSI, so it's still got cushion too!
Fun to ride and no longer work to ride.
Now about those brakes...

It made that much difference?
Is it the tread pattern?

Canoe's post about 8 psi brings up a question. When I'm doing any serious four wheeling I lower the pressure in my tires on my Jeep. I'd never gave it a thought for my bike on the Playa. I have a gifted 21 speed Schwinn Suburban Mountain Bike that I've use for the last few years on the Playa. As a standard I've always kept the tire pressure at 50 psi. Maybe I should lower it to the minimum on the sidewall, 40 psi? Maybe lower? Hey, Elliot chime in here! :D

Must be?
Tread pattern with tread height?
Both are the 120 TPI versions (not the 27 TPI), so the cases should absorb the least amount of energy as it rolls.
The Endo ("Endomorph", just discontinued) and the Larry are fairly similar. The Endo has very low knobs across the width with a higher row of knobs at the outside; gives you more of a square profile across the bottom with lots of tire to ground contact. The Larry is more rounded with higher knobs and a row right down the center. I don't have a shot showing the profile difference well, but Endo is on the left/rear, Larry on the right/front.

Endo on the left and Larry on the right.jpg


I never realized how much of a difference that made, as the Endo on a 47mm Trials rim still has some of the Beast steering issues, and the Larry on the stock 100mm rim is still rounded (even when loaded at 8 psi), such that the steering issues are gone. I suspect the difference must be due to the extra rubber on the ground across the width with the Endo. Here's some tracks on sand. You can see how the Larry will sit up on it's knobs on hard ground or pavement, and with the rounded profile it sits on the center of the profile so we say bye bye to the Beast steering issues? (Endo track on left, Larry front & back on right)

Pretty straight forward. Used a 1.5" hole-saw to drill them through after removing the tire, tube and rim strip. Rim was sitting on ground (as in photo) only I was holding it from twisting with my legs. Ease up on pressure as it goes through so you don't hit the spokes with the saw. I made a template to mark the center for drilling, cut so it fits snug between the nipples and the rim wall, so you're not thinking/judging as you mark the centre. Used the point of a needle file to mark the rim, to get a slight indent/hole to start the guide bit of the hole-saw. Note that the two rows are not perfectly aligned (top nipple is slightly to left of where it should be). For the holes positioned to each side of the valve stem hole, I used a 1" hole-saw, to keep more metal between those holes.

Oddly, I see (or don't see) that I didn't take a photo of the drilled out rim...
But here's someone else/s (1.5" drilled, 1" not done yet)

He'll likely want to know the rim width and the tire size.

8 psi is pretty standard for fat bikes. Usually 12 to 15 psi for pavement and down to 3 psi for snow & some sand. 3 psi on a stock Beast is rather interesting riding on grass, just for a hoot.
