I have got to build a lowracer. My favorite is john tetz . Dad is 90 and gets around great but l gotta get him riding. He plays golf 2 or three days a week.

I will make of carbon fiber. I make and sell square cf tubes on ebay. I will have a new style boom, @ rear will be 26" & 20" up front.

l like john's more uprite and shorter angles:


Will look like this from seat backwards but with no frame. It will be hardtail unibody with no frame. l will use cf 12K twill, innegra, nomex honeycomb. l will use my velomobile mold to make rear, this unibody 2 wheeler will weigh less being all carbon. Enclosed chain canal under seat all the way back to rear derailleur. Enclosed wheels front and rear. Sturmey Archer drum hubs front & rear.


Will have chain canal, runs whole length out to rear bulkhead. Help keep stuff clean.

Carbon fiber square tubes up front will be glued with hysol aircraft adhesive: Also will need uv clear cote over carbon. Or a color. l have seat mold and iam making a new seat (plug) with lil' more height for neck & head.


Maybe a pinion: below 18 speed, maybe to heavy up there.

Different rear seat mount:


carolina Posted - 02/19/2018 : 06:21:23
A lower boom soon closer to front fender, front fender will be carbon later. Have new rear aluminum seat mount hardware from df velomobiel.

Great to have the front fender mold complete:

Kirk gave me this stand, i made it wider. Will put lowracer boom back on in front lil lower. This will help hold it upright on table.

Finally after months of casual work on 20” full fender well mold i am prepping. Will use these molds to complete my rear components that make my unibody a 4 wheeler (rear wheel wells).

Black epoxy tooling gelcoat and carbon and soric over tooling gel. I always keep learning tips and tricks for plugs and molds.

Before frekote l buffed split mold with wizard compounds and my flex german made hand buffer. Dont be home without it.

LETS NOT FORGET DURATEC PRODUCTS/YOUTUBE , compositeenvisions.com, and rev-chem in Southern California.

U see the yellow can of frekote product.
1) frekote cleaner gallon size
2) frekote sealer 4 coats
3) frekote release 4 coats
4) 7 coats of the great TR mold release wax (ebay) over frekote.

Brevity and misspelling rampant (new eye lens couple weeks ago)

Front fender full wheel wells /20”. Will be on ebay/ free shipping.

My channel:

[edit] this split mold finished & curing . Nice to have this full fender mold. I will also use this split mold for my wheel wells at rear on my 4 wheeler velomobile unibody.
carolina Posted - 12/31/2017 : 15:52:51
Left side of split fender mold is complete and curing. Black epoxy tooling gelcoat and carbon fiber twill 11oz. Used compositeenvisions.com medium cure speed epoxy run through michaelenginneering.com pump.


Pop off fence tomorrow night and clean & wax that side ready for a finished 2 part mold.

carolina Posted - 12/24/2017 : 20:34:18
Photobucket is down:

Worked much more on the fence for two part mold of the front fender plug. Takes me so long, about 8 hours to finish & fix that fence. Now i will wax the plug 7 times with TR, reset fence and make the first side of the mold which is easy.

I learned alot from this video and buy from these UK people.


Did switch to lauan wood ($7.48 Home Depot) on larger velomobile rear cowling plug to make the plug “fence” instead of using polycarbonate.The youtube above technique and the lauan wood made it easy. Nice to have these two plugs ready to make the split molds/tools from them.

Ya might have use for one someday. Iam putting one on my 2 wheel lowracer and re-direct the boom. I can put em on ebay too.


warren Posted - 12/08/2017 : 08:33:49
That's cool.
carolina Posted - 12/07/2017 : 19:35:06
Front fender plug, alot of work to only use one time to make the 2 piece mold.

20” fenders /carbon or fiberglass.


carolina Posted - 11/09/2017 : 19:50:18
Gonna re-doo boom /bb lower when l get time.

Gonna attempt a cf frame in my jig . Fb cargo bike. Gonna just stick with my cf velomobiel unibodies. Love making em. Fatbike is not a headache, can't find 2 wheeler recumbent I like.

Working on my motor home:


Try to buy this in January:


Speedbiker Posted - 09/16/2017 : 08:26:09
They bash your neck if you fall that way.

I race fatbikes in winter. Very fun.
Speedbiker Posted - 09/15/2017 : 05:01:08
That's weird. Anyway, I hope you didn't build that over the shoulder frame tube. They are quite dangerous in a crash.
carolina Posted - 09/14/2017 : 12:18:42
What happened to the post again?

Oh well!


carolina Posted - 08/30/2017 : 17:42:19
Gonna build a neck boom on right side . Pic below! Balsa wood sanded to shape with cf. SOB want move then. Well l hope. Gonna slam the bb down a lil to then see if i can get frt fender mold complete soon. The frt fender on john tetz bike is my favorite part.

Rob's below: it's aluminum l think.

carolina Posted - 08/30/2017 : 10:18:45
I have it weak lateral under the seat, some more work. Check out my "fork you" thread for more advanced jig fixtures. Recumbent frames, cargo frames, fat tire frames & frt forks and rear stays.

Thru it back in the jig fixture. Gotta make some more cf sq tubes, iam out! Need some for this and my quad velo.


I ride the shop-mule below for a over 3 years, love it. Gonna convert this metal frame to cf maybe someday. Take me a while to make a few more cf tubes. Speedy with my airbladder mold that stays up 20 hours, then i hold vaccum to pull latex tube out which has mclube release on it.


carolina Posted - 08/28/2017 : 15:47:31
I have lil' to much flex under rear w well but l can fix.

carolina Posted - 08/26/2017 : 09:47:31
I see. ,,, put chain on and try again l will. The side street is level. THANKS. Lowracer BB is 21".

Speedbiker Posted - 08/26/2017 : 07:07:10
Ha! Not remotely the same! Higher seat, lower relative pedals make for a higher cg, giving your more time to react. When you ride the lowracer be prepared to quickly work the handlebars as you start. If you fall it is only because you didn't keep the bike under you.
carolina Posted - 08/25/2017 : 19:40:38
Thanks guys!

I will try, i just wanted a roll down. I will put chain on a go to parking lot.

I rode this below for month or so kirk left here with no problem. Ya would think no problem w/lowracer.


warren Posted - 08/24/2017 : 13:49:42
I agree - you built it right, just practice riding it. It wont take long. It's amazing how fast your brain figures it out.
