Well it has been a couple of years since I first came up with the idea of building a short travel bike . lots of time spent on auto cad working out angles geo and clearances, originally I had planed to get some plates CNC cut and have the swing arm as a bolt together unit but as happens I kept putting other (paid jobs) ahead of this build . I have been working on a new suspension frame design with a good mate who is a gun when it comes to suspension design so I figured now was a good time to revisit my half finished frame re working the swing arm design to be more in tune with the style of frames I am planing to build in the future. To this end I learnt a lot and I’m very happy with the end result, I’m looking forward to seeing how she performs on the trail.

Stay up right ūüėČ

This is the second frame I have built for Terry ,
This time round we went for a lovely Columbas life tubed Phil woods eccentric BB single speed frame. In the past I have used 45% silver to fillet braze the aero tubes to minimize heat distortion on the tubes as you have very little play in the way of cold setting with the life tube sets but this time I chose to use mag bronze and a very careful tacking and welding sequence she came out perfect . Terry chose the color scheme for the frame and with all the rest of the components done in black this will be a very striking bike . Hope you Enjoy her Terry .

Well I just got back from the first Australian custom bike show , and what a weekend it was . There was an amazing selection of beautiful bikes and accessories on display from all the builders in oz but the best part had to be that all the builders where in one room ( to my understanding it the first time it’s happened over here ) this gave punters the opportunity to put a face to the people they had heard about or been following and to see up close the workmanship on display , and from a builders perspective it was fantastic to see what others are producing and through around ideas on what people use and why . All in all it was an amazing event and may thanks go to Andy from fyxomatosis for organizing the event , and I’m already working on ideas for next years show . Hope to see you there .

well this was a huge project .

Peter came to me with a couple of prototype frames that he had built him self (very nice work to) any way after talking to Peter and seeing his frames I took on the project of building him 2 frames one for him and one for his partner but i liked the concept so much i decided to make 2 more one for me and one for my partner. so now i had 4 frames to make

well after a lot of cad work i had all the fittings drawn up and then sent them of to get CNC cut buy John from cycleunderground, john did a fantastic job as always while he was cutting the fittings I had to design and fabricate custom jigs for each section of the frames 5 in total, This turned out to be a time consuming and fiddly job it took almost 3 months to complete them.

next process was to start to build each section again with 4 frames to do this was a long some times painful process but it was cool to start to see them come together .

whilst the building was going on I was working with Peter to organize the wheels , as the bikes use 12” wheels there are no options to build any sort of quality wheels with the rims that are available in the market so i organized to get some custom 24 hole rims made up for the builds ,but with the minimum order for custom rims being 200 units i have quite a few still under my house. next in the wheel saga was cutting custom spokes, peter used his cad skills to draw up the spoke lengths but what works on the screen does not always play out in the real world and lacing the wheels required several sets of spokes to be cut till i got the sizes right and let me tell you lacing and tightening 12″ wheels really sux . I was well happy to see them all finished .

As the design was not mine and every change that i had to make as i came up against them had to be checked with Peter to make sure it would not affect the operation of the folding , It was a big relief when i dry fitted the first frame together and it all folded as it was supposed to do.

I had Peter and his partners frames wet painted buy the master hand of Peter of star enamelers and as always they came up beautiful . for my frames I was trying out a local powder coated John at advanced abrasive blasting and powder coating with fantastic results he does amazing work and we are working on some very cool color options at the moment for the last frame that i will be displaying at the custom frame show in Melbourne in Dec.

one of the main faults with Peters original design was the handle bars the first time i rode his test frame the bars folded under my arms and i was only roiling around the car park so I spent a lot of time coming up with a simple yet very solid braking handle bar set up. the end result is very nice and i have no concerns about them letting go under me .

well the last thing is how do they ride, i have to say very well the design is very solid with very little flex threw the frame they fold down quickly and neatly and are comfy to cruz around on, the 12 ” wheels are not the best for holding speed and you dont want to find any deep pot holes but the frames will accommodate¬† 20″ wheels but you cant fold it with the 20″ wheels in the frame. but I really enjoy riding my little bike and im looking forward to hitting up Melbourne on it in Dec .

All in all this was a monster project that took a year to complete and to many hours to count and though i have a lot of ideas to improve the design further I wont be going back to building these monsters any time soon.

Here is Ben’s new play thing in the raw. (and you thought your fixie was original ūüėČ

I called this post Ben’s¬† what. The . F#@* !! because im pretty sure this is going to be the first thing people say when they see this bike riding by followed but Why.The. F#@* !! then buy can I have a go,. and if your lucky enough to get a ride the first two questions will be answered pretty quickly.

This is the second frame I have built for Ben. The first was a single speed 700cc custom special here is a link to some shots of it

http://primateframes.wordpress.com/2009/07/22/bens-singlefixedeverything-bike/

Well Ben Is a very interesting customer he always has something new attached to his bike  or has changed the set up to suit his latest riding style. I like the way Ben thinks about bikes and his style with them, and when it comes to building for him he keeps on my toes.

He Will rock up with some crazy set up bike or a bunch of  sketched drawings of the ideas he wants to put into a bike, I have to then work out what will work and what will get thrown on the cutting room floor.

So when Ben rocked up on his 12″ folding bike with a hand full of drawings and told me he wanted me to build him one I had to get the gray matter working to work out how I was going to make 12″ rear 20″ front wheeled bike fit a 6′.2″ rider and make it ride smoothly and handle properly !

the first hurdle we had was to find a decent rear wheel no small feat let me tell you. Ben spent a lot of  time searching the web to find any thing remotely decent with not much luck. In the end we went with a 16 hole steel pram wheel I then had to get a 32 hole 120mm Miche track hub and lace it every other spoke hole. It was a fairly tricky build but it came out well in the end .

With the wheel¬† sorted it was time to work out the rest of the build around it, after much to and fro we settled on a 20″ front wheel and the 12″ rear. Ben had been fitted up by Steve Hog from cycle fit the first time I built a frame for him so I used the measurements and adjusted everything to fit the new wheel size. after a few tweaks I¬† had a design I was happy with , then it was time to start to build¬† her , she came together very well and quickly. I had a good excuse to use my new tube bender for the stay bridges¬† on this bike and im very happy with how they came out .

for the forks I had a set of MTB lugged crowns that I thought would be very good for this build after talking with Ben we went with them and the forks you see in the photos were born.

After I had every thing built we decided to  build the bike up for a test run prior to getting her painted. Firstly as we are planing to build a rack on the front forks and I really wanted to see how she would ride , this being such an out there build though I knew the frame would fit Ben I really had no idea how it would ride or handle with such a small rear wheel.

well after prepping and building up the bike it was time to give it its maiden ride. A little bit apprehensively I threw a leg over her and off i went. A quick run around the car park and i had a big smile on my face she felt really nice to ride. With very neutral¬† handling being¬† quick and nimble but very stable you really didn’t feel as if you are¬† on a tiny wheel bike at all.

so now we are working out the carry system for the bike, im designing a front platform rack running of the front forks and then i will be making a trailer for the back.

Ben has kitted the bike out with a nice  build kit,   schlumpf high-speed drive crank set/ Chris king head set/ Thompson post / brooks saddle/ he has not decided on the front wheel build yet but im sure it will be top shelf.

Well all in all I am very happy with this build. It is always nice to have some thing turn out better than you where expecting it to be, and with a very funky color scheme planed for the frame and some cool head badge bling this is going to be a seriously custom build. Keep an eye out for the finished shots.
