Tire update - Been using the 26x4, wire bead Devis8or on the front for a while now & it corners much better than the stock Beast tire. Bigger spaces between fewer & larger knobs sticks to loose over hardpack & sandy dirt better than stock. Have not had much rain lately but expect it will shed mud more easily as well. To review the weight difference, the stock tire is 6 lbs 3 oz. (and is the lighter or the two stock meats) The Origin8 is 4 lbs 11 oz. Some of the weight reduction will be negated by the sealant I've decided to add. Just too many hole pokers in the desert around here.

Also worth noting that while these are marketed by Origin8, they are made by Vee Rubber, as is embossed in the sidewall.

Have a Vee Rubber Mission in 60 tpi (folding) on the way & will report after some swapping & riding. :)

Also ordered a 20T cog to try on the back.

Blue Mongoose Beast looks attractive and eye catching. The frame and the design is appreciable. Total weight of Frame, fork, bars, seat, etc - 24 LBS makes it heavy and attractive to ride to enjoy journey.

Welcome Perez! You may have been a bit dyslexic in your weight estimate in pounds, although 24 Kilos would be closer to the actual weight. :P I haven't weighed it yet with the new lighter tires & without caked on mud, but I'm guessing it's around 44 lbs now.

Have not updated this in a few months so though I'd post latest pics. The Bell 700 gel seat leaked after four short months so that's the Schwinn Deluxe Cruiser seat I pulled from the dormant Genesis 29er. The rack was added a while back (also off the Genesis) for a cooler or extra gear, or stuff I find in the desert. It has 4 LED lights that do an adequate job for riding around the property at night. Rained for 3 days last week (3" here!) so the chain needs oiling.

The only factory casualty is the left plastic pedal is starting to split at the outer bearing. Will be replaced soon with large platforms. BB & axle bearings have been greased twice since July - it's been in lots of water & sand - and still have plenty of life. Will get a sealed cartridge BB this winter if I can find one at a reasonable price. Also have a 22T cog I have yet to try. Legs got stronger by mid Aug & got used to the 18T stock unit.

Pleased with the Vee Mission on the rear & Devastator on the front. Both are slightly taller & wider than the stock street meats. Certainly better in mud, loose over hard pack, & soft dirt. Guessing that combo would be good in snow if you can't afford $150 each studded fat tires. In sand there is slightly better control but you still can't maneuver over about 5 mph. ;) Flats have been a bear. I'm on the second set of tubes & each has 3-4 patches. I run 6-8 oz of Stans in each tire which usually gets me home. But at the low PSI these run at, the stuff most burbles out the holes. Really works no better than Slime in this application & will probably go back to that for the price.

So It's been 6 months & all is good except for the pedal issue. The bike is outdoors 100% of the time & is ridden at least every other day to 5 days a week since July. Since it's from Walmart I'm sure the frame will crack & wheels will fall off any minute now.... :P

Got a new Sunlite 32T crank with forged alloy arms via Amazon tonight. $20 landed. 15mm pedals. Also 156mm crank arms, a little shorter than stock (haven't measured the old one yet) which is fine. The bottom bracket rides low enough that I frequently ground the pedals going over low rises/small hills. Pics & weights to come.

So here's the old 36T next to the new 32T crank. Have not weighed the old crank yet, without the pedals, but the new unit is 510 gr. Aluminum 154mm arms w/ steel chainring. Old arms are 170mm.

Although it had been greased in Aug, it was submerged in monsoon water the same month. Now it's as dry & rusty as Madonna's...
On closer inspection there was still some of the white lithium marine grade grease still present. But not much.

In case you didn't notice, there are no spindle bolts. The spindle is threaded on each end so be careful when removing the nuts. F@ck up those threads & you are out of luck. Nuts are 14mm.

Was losing light so did not finish. More later...

Had sprayed WD40 in the BB housing last Aug too. Was all I had around at the time. This time I cleaned the rust & greased it with the grease used on the BB bearings.

Getting a new KMC chain in the AM. Got a pair of $15 Wellgo platform pedals at Wally World. Hoping they last a year ;)

Looks good, and now you have a little more ground clearance along with more useable gearing.

Took it over some roughs the pedals used to bottom out on & did fine. Still hit but not as much :) More usable gearing turns out to be an understatement...

FYI - I found that the Beast also comes with a KMC chain as stock, but without a cool master link ;) Cut two links out for the smaller crank.

I think the Beast should come with a 32T or 34T front cog. 32T x 18T is great in sand, washes & dirt hills, and while you'll get some relief by just changing the rear cog, you get more torque to the rear by changing the crank and/or arms. The shorter arms get you a shorter stroke & although slightly less torque, but don't leave you spinning like a BMX in the straight runs. 34Tx20T w/170mm arms might be ideal.

But the wisdom of Pacific I think is knowing that most of the Beasts will never see terrain more rough than paved bike paths, sand pits under monkey bars, & dirt hills in vacant lots. Most of the youboob videos about the bike confirm this theory. Stock 36T x 18T is a comfortable cruiser ratio on pavement if you don't have many hills involved. I'm glad I left it that way for six months. I still have a 22T rear I tried for a day or two (I think) but it didn't gain near as much power as changing the crank. Might try that rear 22T again just to see what it can climb :P
