KC's 4-stroke 3-speed on GT2A-S gas tank frame

I have been itching to build a high end bike from the ground up on the cool Grubee GT2A frame designed specifically for motorizing from the in-frame 2.5L 2/3 gallon tank to the engine friendly frame geometry and I finally have my chance.

I have a customer that wants a 4-stroke 3-speed shifter like Big Red, but without the 'barnacle' gas tank.

I went through all the common options but as his budget grew so did the options until we got to GT2A frame which made for a ton more options.

Anyway, other than a base color theme and look I had him start with from the options of 3-speed wheel sets I have a big pallet to work with.

After an hour in my local bike shop with nothing but the bare painted frame and wheel set I got it on it's feet and rolled it out the bike shop door yesterday.

The is no easy way to explain how cool it is to have great little small business bike shop around corner that has actually grew to accommodate my business needs with MB enthusiasm.

They have a work space for me to do things so I looked at tire options and finished the wheels and then moved on to picking the right fork, headset, handlebars and seat post by trying them on and looking at it.

But back to the build...
I had my local auto painting place paint the frame, chain guard, all the SBP 4-stroke shift kit parts and other misc parts to exactly match the rim color.

They did a nice job.
3 coats of primer, 2 coats of paint, and then 3 coats of sealer on everything.

Some parts specs:

Fork:
RST CAPA
Weight 1980g
Axle to Crown Length 460mm
Crown Race 30.0
Brake Type Cantilever, Disc, Linear Pull
Wheel Size 26"
Travel 80mm
Front Hub Spacing 100mm
Front Axle Type 9x1
Spring Coil
Wheel Mount Center Offset 0mm
Steerer Type Straight

KORE headset with 5 1/2" forward offset and 'just right' beach cruiser handlebars.

Tire Parts:
Standard inner liner.
Sunlite 6321 HD thorn resistant tube.
Thick 'special material' outer liner.
Kenda K1008 Flame 26x2.125" Cruiser Tires.

I really like Kenda tires and the cool flame tread design and not just because my wife's name is Kenda ;-}

Obviously more to come but I couldn't resist posting about this new build as it comes along from this point ;-}

*Note I made a topic here http://www.motoredbikes.com/showthread.php?42525-GT2A-S-in-frame-tank-frame-for-MB-s
with pics and specs for a real close up look at what th4 GT2 frame is and what is really required to build any MB with this frame as the base so please refer to it for frame details.
 
Really nice build, love the detail of the big pics.

Do you think it would take Schwalbe's Fat Frank 26x2.35's?

What headset does this frame take?
Thanks.
I built that early this year, my topic about it is here http://kcsbikes.com/topic.asp?TOPIC_ID=696

Tire width for the front depends on the fork you get, for the back the V-brake bosses limit you to 2 1/8", to go wider you'd have to cut them off which would not be wise unless you have another brake option.

I ran this on the front:

Specs:
Fork:
RST CAPA
Color Black
Weight 1980g
Axle to Crown Length 460mm
Brake Type Cantilever,Disc,Linear Pull
Wheel Size 26"

Spring Coil
Defined Color Black
Steerer Type Straight

KORE headset with 5 1/2" forward offset and just right beach cruiser handlebars.

Tire Parts:
Standard inner liner.
Sunlite 6321 HD thorn resistant tube.
Thick special material outer liner.
Kenda K1008 Flame 26x2.125" Cruiser Tires.

Cool bike, I like the attention to the little details.
Thanks chainmaker, like you I think the details matter.
The more bikes I build (85+ so far) the more I tend to continue to focus on the little things like cable length matching and painted parts for ascetics once the mechanical is good.

This is the link to what I have built the last 4 years showing all to start but you can sort them by engine and drive type, and all build have their own topic for details.

Pretty cool I think ;-}
 
I'm not sure whats going on at the moment, but I can't see your pictures. Couldn't see them in some other posts also. Temporary maintenance on your image host? I'll be sure to check back later.

Ya, server is down this morning, it'll be up before long.
 
Thanks for the info KCvale. I have a couple of fork options in mind that should work. As for rear brakes, I am looking at a rear disc so the v-brake bosses can go. As mentioned it is all in the details and you obviously take care of them.

There is no brake boss for a disc on the frame. I'd go with a disc fork and brake on the front and keep the V's for the rear.
