r/fatbike

I’ve lurked this sub for at least a year, and now I have a few questions. I got this State 6061 Trail Fat Bike a while back and just recently swapped out the fork for a Surly Ice Cream Truck fork and added some Avenir (remember them?) bar ends which totally make this bike a joy.

Interested in two things:
An easy front rack. I didn’t see one in the Old Man Mountain catalog and Surly (oddly) doesn’t seem to make one.

A thru-axle with a handle on it so it’s easier to get on and off my car.

Cheers!

I built a tall bike based on a Mongoose fat tire bike, but I don’t know the exact model. I’m trying to figure out what bottom bracket fits it, ideally a sealed-bearing BB to improve reliability.

Original bike/frame: https://www.karrotmarket.com/buy-sell/3id5d7sge3rs/?srsltid=AfmBOoq932rnoXASGd_Y5XQcgCjP5rw7Lgt6avfL4cKlxGkNHLJSSRHb

The BB shell looks close to:

• ~4 cm diameter / ~1.57 in
• 11+ cm wide / 4.33+ in / 110mm+

Attached are photos with measurements. I googled common fat tire BB sizes, but nothing seems to match. Please help me identify the BB!

Pros-cars give me so much space

Cons-I have 2250 feet of elevation left and it is 100°F

What I wanted was some extra wide fencers to protect the CYC X1 motor on my Borealis Flume, but after looking high and low I could t find something that I wanted; or should I say I could t find something wanted at a price I was willing to spend. So I did what I always do, fab my own.

Started out with the Planet Bike 65mm wide ‘Cascadia 29’ fender. Split it down the centre then pop riveted into a 4” wide 1/8” thick piece of HDPE. Cause the bikes colour scheme is burgundy wine gold accents I decided to use gold anodized pop rivets with brass washers underneath the backer washer on the inside is black stainless steel.

I still need to finish off the mudflap with a piece of inner tube from a truck and do some sanding here and there, other than that I think she looks pretty good; especially when I’m having to do this in my tiny apartment not my motorcycle shoppe where I had all the space in the world. Anywho got a truck tube on order some vulcanizing adhesive to glue it in place might even use a couple pop rivets to keep with the theme and add strength.

While I wait for that to get here I’ll move on to the rear fender.

I recently tore the sidewall of the front tire on my Kona Woo, so it’s time for an upgrade. In addition to converting to tubeless I’d like to replace the Vee Snow Avalanches with something better. The intent of the bike is to ride mostly snow, groomed fatbike trails in the PNW, but I’ll admit I take it on adventure rides in the summer on rocky singletrack and down closed muddy fire roads.

I’m leaning toward an even bigger tire for more flotation, but I’m not sure how much that will be hampered by the 80mm rims, nor how much more tire I can fit on this frame.

I’m currently considering the Snowshoe 2XL PSC, Terrene Johnny 5, Jumbo Jim 4.8, or Surly Bud/Lou combo.

I’d love to hear your thoughts and experiences.

Today was such a perfect day to ride a bit and return home sunburnt, thank you sun, I hate you.

Raining all day after work but had to get out with the Farley after ive been sick during the weekend 👌(new helmet, first helmet 😅)

Lemmeno, thanks

Found this gem wrongly advertised as a Surly on a marketplace in Austria for a steal. Friend shipped to me and I stripped it down, applied a flask of nail polish and built it up with 29+ wheels and a 1x12 eagle drive train. That bike rides fantastic!

Someone else posted about doing a conversion to SS for summer gravel grinding and I just had to take advantage of the opportunity that I haven’t yet. I have had the Pugsley for a little over a year now and spent a lot of time optimizing it for easy climbing and getting the gearing on the bike I know I can trust when it’s super hot and just way too hard.

Finally decided to just move a few parts around and get the SS kit onto this bike which I’ve never tried.
So far I’m amazed at how much lighter the rear and is, and the whole bike feels like it post 5 pounds, not actually sure I didn’t weigh anything.

Running 26/18 which should get me right at 43 gear inches, and I have run 43 gear inches all over my local trails and know it will clean anything out there as long as I’m able to put in work.

The only risk in running is that I found an old 9 speed chain that was missing the quick link, so I went ahead and partially broke the chain and put it back together. Didn’t use one of those special pins that break off, so hopefully it holds no issues on first ride out the door!

Trying to ride more drive less, so today I used the trailer to take an old sewing machine and snowboard boots to the secondhand store.
