Catrike Monster Expedition

Get your own 2012 Catrike Expedition
This Expedition has our Catrike Wheel Extension Kit installed so we could put a MONSTER 29er wheel on the back. This is the beefiest trike ever built!

Get out of my way!
We like to do some projects just for fun here at Utah Trikes. When I asked the gang what the biggest wheel we could fit on the Expedition this is what we came up with. We had to kick it back with our Extension Kit and it still barely fits. There is a lot of air in the tire, so it gives a real smooth ride.

Large Marge
The Surley Large Marge is a 26x4" tire. It is huge!

Shimano Alfine Hub
There is just no way to fit this tire and a derailleur system back there, so we went with our favorite hub -- the Shimano Alfine. It shifts nice and when paired with the Schlumpf High Speed Drive gives a great gear range.

Headrest
The headrest in the pictures was barely placed on there and needs some adjusting. We had been riding it without the headrest until my hoody got caught by the wheel. Ugghh! I'm thinking a big Harly type fender would be cool.

Big Tread
This was the least aggressive tread we could find in this size. Once the center ridge wears down it will be awesome on the road. As it is though, it's a very smooth ride with just a little rumble on smooth concrete.

We had the pleasure of riding this awesome machine when we spent the day with Ashley and his crew picking out our new trikes. We wanted to ride a trike with the Schlumpf high speed drive and Alfine hub. The large tires give an incredibly smooth ride. The Schlumpf and Alfine make shifting a breeze. Despite the large tires still an incredibly light trike. We decided on his and hers Expeditions with the Schlumpf and Alfine.

Well, I think I'm glad that I just got rid of my Expedition. That looks like something I would have had to spend money on to do. It just looks RIGHT! Thanks for sharing it with all of us.

the Tommisea spider tires are just as wide, but should have a slightly lower rolling resistance due to its less knobby pattern.

It's a clever way to promote sales of your rear wheel extension.

No way to fit a tire this big without them.

Way Cool!

I've been researching the Schlumpf until I came across your site and what you do. Most dealers will tell you what you can do, you guys do it and what a great way to sell your products. I wasn't that interested in trikes before that, now I am.

I see a spoof video in the works--this beast in a Portland, Oregon bike lane waiting for the light to turn green, while a muscle-car type pulls up alongside and does a stationary "burn out" (just to dump a lot of smoke in the air...)--so this Cat's rider responds "in kind", and leaves the muscle car dude with his jaw hanging...

Now that is an all season trike and certainly worthy of off road expeditions. I have Surley Pugsly and with two of the large marge rims and tires it is hard to stop the trike though would add the deminsion of never falling over. Great job.

And the total weight is?

Haven't weighed it. The rear wheel/tire is surprisingly light though.

DAMN.

Awesome trike. Was wondering though, can you still get a rear fender on this monster? Also, did you maintain the standard 20" on the front? If so, what seat angle now?

There is no ready-made fender that will cover that fatty rear tire and fit on the Expedition. I'm sure one could be adapted though.

The front wheels are the standard 20" rims with the Crazy Bob tires.

The seat angle does not change, at least by much, because of our extensions which raise the rear dropout.

Nice! I like the look of the Schlupmf with the no-post/Villager boom, too (just like mine!) Did you have to put a spacer behind the cog or something to get the chain to clear the tire?

We laced the wheel with a slight offset to allow the chain to clear the tire.

Hey, could a trike with this mod be motorized, as well?

It would require a middrive.
Either gas or electric would work.
Posted by Ashley

how does the large tire affect the speed? I know the ride should be softer, but do you have to peddle alot harder for the same speed as stock tires? How about durability and flat resistance of these tires?

It is not a racing setup. It's fast, but the tire is not the fastest.
Posted by Ashley

how much for one finished out just as this one is in the pic?
