Let's see how your kids roll. Tell us about your kid and what he/she likes about the bike.

How have you customized it or improved it fit their needs.

Building this up for my son's 8th birthday in December:


Marin Bayview Trail 24" mountain bike. Stripped off all the stock components and replaced with:

• Raceface Atlas cranks + BB
• Raceface bars
• Surly 1x1 fork with cantilever bosses removed
• Oury lock-on grips with Odi clamps
• Avid BB7 front disc
• 24"x2.5" Surly Large Marge rim up front
• 24"x3" Nokian Gazzaloddi

Still waiting on the rear wheel build since I am going to complement the 32/22 front chainrings with a 11-32 Sram PG970 cassette in back.

Part time framebuilder...

and the kids benefit from having a bike geek Dad. A proper fitting and handling bike helps a kid even more than an adult. I love to build kid's bikes: there is an interesting design challenge getting the small bike to handle correctly and still be useable for a year or more.

As I said in another post, I was feeling a bit sheepish about spending $300 on 24" wheels...until I talked to another Dad at karate class and he told me he pays $1800/year for each son on ice hockey ice time. And that doesn't include equipment! Yikes! Any of us could use that to justify a $1000 mtb no problem!

I think all of these have been posted before - and the green shirt pic is a couple years old now (that guy is getting a super 24 this winter...he is just an awesome rider, and now too big for the 20. He has put more than 600 miles on that bike this year.

Cheers! Get the kids out there and do not skimp on the equipment! B

He loves the fork, it's so smooth. He also loves the color (so do I), he picked it out himself.

He loves to ride trails. His favorite is the standard TNGR loop at Long Ridge OSP. It has a good mix of shade, singletrack, long descents, climbing, switchbacks, and technical bits for a kid.

I'm lovin the nice hand-me-down saddles. Most saddles that come with kids bikes are garbage. Our cushy saddles are better for them.

Seeing some good pedals too and not much of the $2 plastic ones.

One more for the list...

I picked up a used Giant XTC JR 20 on craigslist. It's still too big for my son who just turned 5, but I couldn't pass up the deal. He's riding it if we go anywhere with hills, but for the local dirt jumps, we take the 16" SS hotrock.

Upgrades:
Easton Monkeylite carbon lorise bars I had laying around, cut ~1.5" off each side.
Sinz crankset with 125mm arms (stock was 140)
Shimano nothing fancy square taper BB
Kenda wire bead small block 8 tires
Not shown, but a friend gave me a Ritchey carbon super logic post. He had crushed the bottom portion of the post and cut it down to about 8", so perfect for the next couple of years.

I picked up a 2005 or so Specialized Hot Rock about a year ago for my son and documented the build then. I have done a few upgrades since. As it sits now:

Specialized 2004 13.5" hotrock.
Stock 165mm cranks with Sinz bottom bracket (dropped nearly 1/2 pound from stock with this)
1x7 with 32 tooth front chainring, Paul Chainkeeper, stock freewheel.
Race Face Stem, Price Point Sette flat bars.
SRAM x3 derailleur and x5 shifter.
Sette seatpost and Odysey BMX Saddle.
Stock rear wheel with Alex rim.
2001 Sid XC 80mm fork with Sun Ryno Lite XL 24" rim and Deore Disk hub (thanks to Chad at Redbarn). For a little more the Sun Envy Light is about 80 grams lighter.
Avid BB7 front brake and Single Digit 7 rear.
Kenda SB8 Tires.

Hits the scale at 24 pounds even.

Caliper 198g x2 163g x2 -70g
Fork
Seat 309g ? ?

Sorry about the formatting, in the edit window it all looks lined up, when I post it I lost the tabs.

If I take the seat post as 145g, then I've shaved off 1325g. Not as much as I hoped, but a lot of it was for the performance of the new parts over the stock one

Intense Balance Bike

My wife thought I was crazy when I bought this during the Christmas sale at Performance Bike last year for around $50-60 (since my son was only 11 months at the time). Had the intense head badge and decals in my toolbox to help fit in with the "cool kids" :cool:

My son loves it since he always see's Mommy and Daddy on their bikes. At 21 months now he can finally touch the ground while seated so hoping to take him out to the park for some practice this weekend :thumbsup:

Here are few pictures of my son's bike. It started out this morning as a 14" Sette Reken and together we moved the parts to a new Jamis Dakar XCR Expert 13". I built him the Reken last august for his 8th birthday with a decent spec and 24" wheels that I built. He's really improved and loved going with me so when Jenson had the 13" Dakar XCR, I bought it. Glad I did he loves the new ride! We will move the Reken to his street ride and also loan it friends when they want to hit the trails with us.
