90% of the fun at 10% of the cost: Mongoose Beast, Walmart fat bike, first impressions

That's my first impression:  90% of the fun for 10% of the cost.

The unboxing

Beast

Yup...  wow!

About 15 minutes from box to riding.  I am 5'11" and it was no issue making it fit.  Simply would not work for anyone over 6' though without a longer post and a cramped feel.

I put all the stock parts on it and weighed it at 47 lbs and then removed reflectors, stock saddle, kickstand etc. as shown.  I did not reweigh it today but promise to weigh it again after some more drastic, still cheap/free, weight reduction measures.  I'll be leaving the chain guard on as the primary use will be commuting.

All of the parts are of decent quality and fit well with no issues right out of the box.  Extremely impressive for $200.

Frame is steel with a 1 1/8 ht, 135ish front spacing, 170mm rear, 100mm rims (I know there was some debate/question about those items)

I lowered the air pressure down to about 6 psi and headed out...

Here is the same shot of my own custom carbon bike...  more here, interesting how the geometry differs etc.

Initial impressions of the handling are that it is extremely stable.  The chain stays are super long and the bike does feel "heavy" but overall it's pretty neutral.  I think it's just about perfect for a true entry level offroad bike.  No trouble to take the hands off the bars and cruise around the city but also agile enough for some singletrack.

The tires are not the "spider" tires that I was expecting the bike to come with.  I was excited about the tread pattern as soon as I saw it...  the solid center is a nice touch for a bike that many will ride primarily on pavement but the progressively taller knobs felt solid on snow, even with ice patches.  They also provided significant float.  Overall they have a slightly larger contact patch at 7 psi than my "light larry's" on 80mm rims.

One of my concerns was how the coaster brake would perform.  It has almost immediate engagement and plenty of power.  It will take some getting used to in order to ride a coaster brake bike on ice and snowy singletrack, but I was immediately having fun with it.

I'm excited to ride the bike more and it will be my every day commuter going forward.  I am confident in the bike structurally for any conceivable use but the reliability of the hub could be a key issue going forward and is one that I'll be watching carefully.

More Pugnago and HIlls Iowa Spring Classic... it's Spring! maybe

This was a really great weekend.

Saturday I got to ride twice and hang out with my daughter a ton.  It was a bit icy out there but I rode the CX bike with regular tires for the first ride to get a little speed.  Then later I rode the fatbike with Kim.  I considered heading out to Stagecoach and seeing how the ATV trails were, but already knew the condition of the trail right by my house.  Franz and I had been out there both Wednesday and Thursday nights from 11-12 or so and it was my kind of fatbike conditions.  Despite the relatively cold temperatures the snow was melting fast and when the snow goes that reverts to lame blacktop so decided to hit it when it could be hit.

yup, I've only really got one fatbike trick

At the time was thinking that riding in the river was a sure sign of spring finally really getting spring here...

Sunday meant up early and off to Hills.   After last weeks (scroll down) non-race I was really happy to hear that it was going to be relatively warm and that the gravel was hard packed.  Took a risk and packed only the Look.

Hadn't gotten to ride it since???  probably September.

Here is the Strava information



I attacked up the 4% or so grade after the very first turn.  The pace just seemed low and I didn't want to go into the very fast/downhill/gravel back-section in a large group.  I expected others to react and just hoped to string things out.  I collected 15 or 20 seconds right away.  At about the half-lap mark I saw that two riders had distinctly come clear of the group and were likely gaining on me.  Decided to allow them to catch as I knew three of us would almost certainly stay away all day.  We rode the next 5.5 laps all together.  No action until past the mid-point of the final lap surprised me, I was most worried about being dropped on a hill and now there were none.  Long paved headwind and some short bursts distanced one rider and again I was clear alone but I was totally out of breath (might have been better off getting less of a gap and not working quite so hard and then been able to hold it to the finish).  From there it was cat and mouse with just two to the finish.  I made final turn in second position and sat in the gutter until opening up the sprint, which was very hard for me as I had picked too hard a gear and the other ride was strong, but I was able to win by less than a bike throw.  Last year at this same race I had felt the learning curve of moving up to 1/2/3 races pretty heavy, so this really felt great.

Took my prize money and some awesome gamjams jackets and headed off to a Mexican place in Cedar whichever on is nicer for Chicken Mole, green chilli and a 34 oz beer.  Glad I had a co-pilot (driver) for the ride home.

Sunday was also St. Paddy's!  Locals were out riding and partying it up and we decided to ride over and check out if any of the fun was still going on.  Got to ride my other Lin Anderson painted frame for the first time in it's current iteration...

It will still need a stem with a touch more rise before it's ideal for singletrack but it's damn fun.

Today we have 2-3 inches of new snow already!  Winter.

It just keeps snowing

Never would have thought it would still be fatbike weather this time of year!  

Have gotten out for three basically "bonus" fat rides recently.  Super fun/challenging conditions all over the place.  Highlights were riding last night with Franz over some barely boot packed, crusty snow and today over thin ice for miles of snowmobile trail.  Getting antsy to switch over to keeping track of my rides in miles, but so long as we are stuck in hour mode I couldn't ask for a better companion than my Pugnago.

Insole test: jaztronaut, lake winter, toasty feet, cycling insole shootout

Been hearing a lot about the potential importance of special insoles in keeping your feet warm while winter cycling.  I was able to round up the likeliest suspects for warmth and do some testing:

polar wrap's toasty feet aerogel insoles

Lake winter boot insoles

QBP's Jaztronaut

then as controls some 'regular' insoles I had at home

the Nike's out of my favorite doper's signature shoes

sidi dominator insoles



Each of the above has a different "take" on being an insole.  With an extreme range of thicknesses and support provided as well.

This is the Polar wrap "toasty feet".  It is very thin and flexible by itself.  Would provide no support, but would likely fit inside your winter shoes in addition to whatever more supportive insoles you would choose.  It was a trim to fit and has already been trimmed for my size 43.5 feet.  It is heavier than expected with how thin it is- could this mean warmth? 

This is what comes inside the lake winter boots.  It is quite light compared to the aerogel options.  It is also just a "slab" type insole though that relies on the shoe itself or another insole to give you support.  It has an interesting sandwich type construction obviously designed to got a lot of air between your foot and the outside world (which is similar to the claims of the aerogel).  It is not quite as thick as the "7mm thin" (as proclaimed on the box) jaztronauts, but it is quite thick.  They would be hard to add to your existing shoes without replacing the stock insoles completely and likely without making them a bit tight for wearing thick winter socks.

The jaztronaut.  Also a cut to fit insole.  These are very thick and quite stiff.  Would be hard to add to most shoes without having ordered a larger shoe purposefully.  Have no built-in support and yet are too thick/stiff to work with an existing insole to provide any.  Have high expectations for their insulative properties based on their thickness and price.

Lance Nikes.  I put these in the test primarily because they are out of the road shoes that I personally wear when road riding is still doable but the temperature is cold...  think down to about 20 degrees F with toe covers and smartwool socks.

Not much to say here-  these serve as a control.  Just a basic cycling insole.

Now to set up appropriate testing conditions...

Weird buying blocks of ice on "snowmageddon eve"

Testing phase...

The feature of the insole that we are trying to test is how much cold they transmit through them to the riders foot in the dynamic environment that is your shoe as you ride.  One of the major claims of aerogel is that it retains it's insulative properties even under relatively high PSI.

My first thought was to use a block of ice with an insole on it and something metal, a wrench maybe?, on top.  The steel wrenches would have a high heat transfer and would hopefully serve as an adequate measure of how cold your foot would get.  However, I quickly found that they were too reflective for my thermometer gun to accurately measure them.  Decided to try ceramic bowls.  Placed two room temp. bowls on the ice and one on the countertop to serve as control.  Was hoping the bowls on the ice would transfer heat/cool rapidly enough that they could be used to measure the insole performance.

After 30 minutes the bowls on ice were both right around 38.5 degrees

The control bowl was at 66.5

I decided to go on using the bowls.  The next test would be if the bowls would cool enough when placed on top of an insole such that comparisons could be made.  If the control insole only cooled it's bowl a couple of degrees then there wouldn't be enough variability in the results to really draw any conclusions.  I decided to keep track of this while running the rest of the experiment concurrently.

But first:

a quick Dickie Dog bath



And then here is the rest of how I set things up:

Basically, weight them evenly, set a timer for 30 minutes...

Results:

Polar Wrap Toasty feet after 30 minutes

Lake Winter insoles after 30 minutes

Jaztronaut after 30 minutes

Lance Nike after 30 minutes

Sidi insole after 30 minutes (control)



First off, not exactly the results I was expecting!  However, the range in values was enough for me to call it a successful experiment.  The method would work and the results were appropriate enough that it would be possible to differentiate between the different insoles and draw some conclusions.  I ran all of the insoles two more times such that they had each been run in each position and starting with room temperature (66 degree) bowls and insoles on each run.  I won't post all the pictures but I found the results were repeatable and precise in that all 3 runs for each insole were within +/- 0.5 degrees.

Next I thought a bit about how the insoles were likely to be used and ran two more options:

I had noticed the sidi soaked up a lot of moisture from the ice previously and hoped this aluminum backed waterproof tape might help that as well as provide some added insulation.

The "cheap" aerogels had done poorly initially, but they are very thin (maybe 1.5-2mm "thin" at most) and it followed in my mind that the above was the most appropriate way to run them.  By adding them to your existing, supportive insoles you actually wind up with the least added material in your shoe and you don't sacrifice comfort or performance.

modifying the sidi insole didn't accomplish much

the combo of the cheap aerogel insole and the doper insole was as successful as any other in this test and still thinner/easier to fit than either of the winter boot type insoles.



My conclusions:

The lake boots or the wolvhammers each come with insoles that work but neither is a very good option to add to some other shoe, at all.

The aerogel technology isn't a big deal in this application.  Neither of the aerogel insoles were surprisingly "NASA technology" style warm. 

Buying the jaztronauts for $50 or $55 is a terrible idea-  but they certainly work and if you sprung for wolvhammers be happy with them. 

Buying the cheap aerogels and expecting miracles is silly, but they do provide something.  They are best for adding to your existing shoe to provide extra warmth.  This would be great for your road shoes or if you work in a warehouse with a cold floor and want to use the same boots you wear all summer too. 

Right after completing this test I went for a ride with my regular old winter shoes as shown here
and my feet got way too hot.




I wonder how these would perform
