I actually had an "all wheel drive" bicycle at Burning Man in '01. It was a regular mountain bike with a little gas motor that drove the front wheel via a roller that simply pressed against the top of the front tire. When you also pedaled it you effectively had all-wheel-drive. It really did help a lot when riding through soft silty sections of playa!

I'm curious how something like this would handle on the playa. The rear tire, that is...with the double chains.

AND, if a tweaked out sealed drive shaft would hurt or help...

The two-stage drivetrain would be fine. The rear tire would feel a bit odd, but no real problem.
But the seating position and the steering geometry would murder you. Without a back-rest, you would be hanging on for dear life to keep from tumbling backward. And that steering geometry would want to go anywhere but straight. Bin dere, dun dat.

By the way, the tricycle I showed earlier was originally a bicycle. Here Miss Gina is getting ready for Critical Tits in 2007:

The only steering problem I had was turning corners inside BRC. Really large turn radius!! On the playa, it went straight, and very fucking fast! Not sure what we did, but the gearing was JUST RIGHT! I kinda liked hanging off the handlebars. Though it's NOT something I could ride hands free, it was extremely comfortable!

Much good info, I’m sure.

After his passing a few years ago the web site is being maintained and even expanded by his colleagues.

Sheldon Brown is so widely revered in bicycle circles that I cannot imagine his site ever being abandoned.
I just bought a bicycle part from a random online bicycle store, after asking the seller a technical question. His reply began "According to Sheldon Brown...."

Anyone ever try this?

It's alkali resistant, however, I'm inclined to think it's just BETTER to replace all bearings post-playa. Or, maybe it's enough to preserve the bearings, till the next overhaul..?

That looks like the white(food grade) grease. It was water resistant.. I used it to grease a machine for whole rug washing. It's a sticky bitch and don't wash off your hands.. Had to use Simple Green to cut it..

On Simple Green, Make sure you rinse it all away.. It's made of veggies and spoils..
Or cooks onto a motor block and stinks up the whole street..

Replacement is not needed.
Just cleaning.

I had some german moly spray that was supposed to be resistant to attracting crap.
Not playa tested though.
Superb stuff.

It may have been due to the rake of my forks, but I had to replace the motorcycle bearings in the head tube on my chopper after each burn. They looked like battlefield relics when I removed them, so I'm certain corrosion had at least a minor role. They were not salvageable.

I was wondering about what type of grease to use, also.
I've got white lithium grease, red grease and green. But wonder if waterproof bearing grease would be better?
I used the lithium grease on my cranks yesterday because it seemed a bit easier to clean up.

:idea: :idea: Just flashed on an idea.. I have one of those new detachable baskets .. Went out and looked at it.. The basket bracket can be unbolted ans bolted the a 12 pack cooler.. In the rear (much smaller than most trikes) there is just enough room for the basket from my walker,, Jella made a wild liner for that couple years ago.. How are you tricking out your bike/trike :?: .. Need more :idea: :idea:

Unjon, do you happen to have a picture of your idea by chance?

I was just talking to my sister about a basket for the front of her bike.

For my the back of my trike I found one of those wire linen drawer basket and another only a few inches deep for the lid.
Im a little worried about thestrngth because the wire isnt as thick/strong as a normal trike basket is.
Found some alien fabric to make a liner for it.

The basket is one of the now popular styles sold at Wal Mart and Big K aka K Mart.

The bracket attaches to the handle bars.. You press a button that releases the basket.. Still to dumb to add pictures.

Never thought of it that way, but being able to ride... "tipsy" seems the best word... is an important criterion.

Just took the Beast for a ride.....had 3 people comment on it in less then 5 minutes...all good!
So I know I havent ridden a bike in a while but WOW the gearing is not even close for me to ride with!
Going to have to change out the back gear.

How is the gearing for you Tom?
