cool, i am not too worried about suing it on snow...for now....

can you give me the details on the mods you did? which parts I should be buying etc.

right now my boys are coming from a fixed gear bike and they need some choice but i do not want to overwhelm them.

does anyone make a similar bike in an 18" rim rather than a 20"...in the same price range?

 

I had some cranks made so I could run the 22 tooth. I also had to run the riser bars as upside down as drop bars because the front end on the bike is really high and I needed a shorter reach. It terms of upgrades if you can switch in aluminum bars, and seat post it would help. The seat is also very heavy. The only other place I would bother to spend money is in the tubes. They are pretty heavy. There are lighter ones out there. The rest of the bike is actually very well done. I have not seen an 18" fatbike of any kind out there. At his small size I wish there was a great 3" tire bike out there to lighten things up a bit. One thing I am keeping an eye on is the shifter. My son keeps shifting it by accident. If needed I will go to a trigger of some sort, but I suspect he just needs to get used to it.

 

hmmm interesting points.
Huffy Wicked Grizzly 20 Inch Boys? Fat Tire Bicycle | Walmart.ca thoughts on this 3.0 inch tire? not a true fatbike but again we ride trails a lot but not a lot of snow or sand.....

 

It is a toss up between the two. I like the Huffy better except for the rim brake on the back. I am really happy with the discs on the Kong. The reach is very adjustable and they work well. At their age it might be a bit of a coin toss. I will say my son likes the Kong on dirt. Lots of added confidence with it.

 

the bike snob in me cringes at the name huffy though lol..but they are 5

 

ya the disc on the mongoose front and back is nice. I will have to take the boys in to walmart and have them sit on the huffy. I think measurements between the two match up. I wonder what the weight is on the huffy.

 

Ya. I get that. It would be a struggle for me as well. The Kong is a very cool looking bike in person. I feel like the upgrades needed are mostly things sitting in your old parts box or that can be picked up used VERY cheap. The crank is the big thing.

 

im sure I could head in to my LBS and pick up a different crank set for cheap.....i love the look for the kong for sure.
did you switch out the cassette?
I appreciate the help.

 

do you have an online source for lighter tubes? just so I know....

 

The crank is cheap. the catch is that you need one with short arms(145) and that will take a small enough ring. BMX cranks don't take a small enough ring so my local shop cut, drilled, and tapped a MTB crank to make it work. Phat Moose in Ottawa. Great shop. they also made a chain guard for it as well.

 

cool, thanks for the info.

 

Just a quick heads up. A company called Stampede Bikesout of California is making a 20" fat bike that looks like a really good bang for the buck. It is on sale on Amazon. It's called the Fat Byke 20. It looks like it is about 6 pounds lighter than the Kong. It is what we decided to order.

 

They claim that it weighs less than 30 pounds, is that correct? I would be all over this if it had decent gearing, but still looks to have the same 40T front ring with the 7 speed thread on cassette that has no real options to be upgraded.

 

There are a couple reviews out there that also say around 30 lbs. I think they are by "twowheelingtots" and "mountainmama." I emailed the owner Ian asking about using a smaller chainring on the crank. He said the one that comes on it is a 40T but said it could be swapped out, which I assume means the chainring is bolted on, not riveted, and he did not mean you have to swap the entire crank. Ours should be here by the end of the month and I can let you know for sure. It is also a freewheel on the back, but it can use the shimano mega-range cassette to improve the gearing a bit.

 

Hard to tell in the picture, but sure looks like the Kong crank, which was one piece of heavy steel with no ability to change. And the 11/34 mega-range is what I put on my daughter's Kong, and it still wasn't enough. My daughter is a beast, and we tried to use it just riding on fairly flat powder, and the gearing was just too high. The only options I could find were trials cranks, and they were half the cost of the Kong. So ended up getting her some 24x2.4" tires for her normal bike, and it worked great, as long as she was not first on a powder day.

 

So, how is the tykesbikes fattie? Just ordered one for my boy (they were on a super sale at tikesbikes.com)

 

I would like to know if I can change the fork for a MTB suspension fork, this bike has a 1-1/8 steerer tube?
For example like this one: RST CAPA 24" SUSPENSION FORK & STEERER | eBay

 

There is nothing that will fit fat tires

I got it Tigris99, what I think is to change both rings too, that it is easy ... I practice Downhill and build my bikes, what want is to convert this to an MTB bike, but I need to know the steerer tube inner diameter on the frame ... I didn't find that information

 

It's normal head tube for 1 1/8 straight steerer. External cups. Nothing special about it as for normal frames there is only a couple standards. External 1", external 1 1/8", integrated 1 1/8, tapered, or 1 1/2 straight (cannondale only I think).

It's not a threaded 1" steerer so that makes it 1 1/8 external.

Headsets are the easiest to figure out though people over think them.

I am trying to figure out why you want to take a 190mm spacing frame and make it skinny tires. Can create the same bike using a 26" MTB frame.

Btw the bike is NOT the size of a 24" bike. Total tire diameter is that of a 26" MTB. So trying to build a MTB out of this frame you need to address it as a 26" bike otherwise bottom bracket is going to be really low, major pedal strike problems.

It was in the morning a couple like this: Mongoose Massif 20 " 7 Speed Boys Fat Tire Bicycle All Terrain Mountain Bike New | eBay
It was a couple for $50 each from China... but It is gone, only there are now these expensive ...
It is important that about the height, but this was a 20" wheel size not 24",... 190mm rear hub in a 20" wheel? ok, I don't know much about Fat Bikes
For a little 6 years old boy that is growing it was a good idea take that little fat bike to convert to an MTB to destroy in rough terrain, but it sold out
I will continue looking for 20" bikes on eBay, there are very few in my city
Thanks for all the information

 

Ya sorry got confused which bike I was talking about. The mongoose I got for my son is 24".

They had Mongoose Pugs on sale for $60 out the door at my local chain store. I picked on up and it seems most the upgrades available are the same as the Mongoose Mallus/Dolomite.

 

SCOOP QUARTER - Mountain Bikes Bike | Silverback Technologies GMBH there is also a 24 scoop half. No idea on cost but the little one is quoted at just over 12kg

 

Quotes 100 mm travel too? Still I wish these would have been around when my kid was little.

 

I have a double scoop quoted at 14.5kg was under 32 lbs before I went tubeless. Certainly look more like real bikes

 

Hi all, does anyone know how to convert the front wheel to a quick release?
