First Look: Angeles' Spade Prototype Was Designed by a 19-Year-Old

Mar 22, 2023

Angeles Spade

The future looks bright for the youth that take advantage of the technology we have at our finger tips today. Take for example, nineteen year-old Ethan Eggert of Bend, Oregon who is producing his own enduro frame under the brand name Angeles. The 170mm of travel “Spade” prototype a CNC'd frame built for enduro racing and freeriding.

Ethan admits he’s had friends help him bring the prototype to fruition with photography, marketing, and 3D printing test models. However, he did design the frame, linkage, and graphics himself.

Angeles Spade Details
• Wheel size: Dual 29", MX, or dual 27.5"
• Frame material: CNC'd 7075-T6 alloy (and more)
• Travel: 160-170mm, 160-200mm
• 63° head tube angle
• Reach: 475-485mm
• Chainstay length: 440, 450, 460mm
• Sizes: L
• Pricing: TBD
• Weight: TBD

The brand’s name and theme come from Port Angeles, home of the Northwest Cup - one of Ethan’s favorite places to ride. After that, he happened upon a suiting model name when he picked up an ace of spades, Bicycle branded playing card, complete with angels on the back.

bigquotesThe idea started when I was helping a friend fix his bike and I was trying to explain how the linkage on his frame could be better but he just looked at me very confused and just said you should make your own frame and here we are.Ethan Eggert

Frame Details

Taking cues from recent manufacturing methods, the Spade is machined from large blocks of billet aluminum to form halves and is then bonded together. Focus will be placed on building the frames sustainably by machining 7075-T6 into shape, but Ethan hints that Angeles bikes won’t be limited to aluminum construction. There's also a strong emphasis on this frame being a prototype and that it is subject to change.

A driving factor in the kinematics for the Spade were a primarily vertical axle path and also a frame that allowed for versatility in the setup, depending on the rider’s style. Basic functions haven’t been left out of the equation either, so the frame can hold two water bottles.

Angeles Bikes weren’t ready to share the kinematics just yet, but the design uses two short links where the upper component is only half visible from the side profile. This upper arm acts as a rocker link to compress the shock from above, similar to Cannodale’s Jekyll.

Between the interchangeable dropouts, geometry flip-chip, and shock travel spacers, the frame to be set up in eight unique configurations. The base is a full 29er enduro bike with 170mm of travel at either end by using a 205x65mm stroke shock. That can be dropped to 160mm by reducing the stroke to 57.5mm and matched with an equal length fork. At the opposite end of the spectrum, the Spade can run multiple dual-crown builds as well; 200/170mm with MX wheels, or 190/170mm with either rear wheel size.

Then, there are the reversible head set cups that give you 5mm of reach adjustment to tune the fit and style of the bike. Ethan claims that the Spade is both, “A race weapon and a freeriders dream.”

Normal standards are also part of the equation with a threaded 73mm BSA BB, 52mm chainline, and UDH-compatible dropout. There are also ISCG tabs and the cables run internally through the front triangle.

Geometry

As it stands, the single prototype is deemed to be a size large frame with a base reach measurement of 480mm (+/- 5mm) and a stack height of 635, which aligns in the middle of most other brands’ offerings.

The seat tube holds a few numbers that jump off the page with a taller 450mm length and 82-degree angle. Then the head tube is also on the attack side being 100mm long and tipped back to a slack 63 degrees.

Thanks to the interchangeable dropouts, the chainstay length can vary between 440, 450, or 460mm. There’s also a vertically offset dropout to compensate for the drop a 27.5” rear wheel would produce. In the full 29er mode, the BB drop is 25mm

All of those numbers add up to a 1289mm wheelbase (in the 450mm chainstay setting) to keep things in check for enduro racing and freeriding alike.

Availability

At this time, Angeles has not yet determined a price but says they will have a small batch of frames ready to sell by the end of the year. To get in touch with Angeles Bikes, you can contact them by email at: Angelesbicycles@gmail.com

 I need to know how he funded machining one of these.. Designing a bike frame is already difficult, but actually getting something manufactured in this way seems like it would be crazy expensive. Would love to know who does the machining and what it realistically costs for a company to machine a frame?

 I used to work in a mill working shop. There were lots of artsy type guys experimenting with CNC stuff after hours. They’d usually show up with a couple bottles of wine and the guy who owned the shop would hang out and have a few drinks. There was one guy who was doing solid works programming during the day and the owner would let him use the table for his “hobby projects” after hours. One guy was machining 4’x8’x3” foam panels and then painting them to make 3D murals. As long as you know someone with a shop, are willing to pay for your own tooling and are flexible about when it’s getting done it’s reasonable to expect this kid could pull it off. Especially around Bend where the shop owner might be a biker himself and willing to eat some of the cost.

 It's possible he contacted a local machinists, showed up with an actual design and plan, and someone decided to help him out. Either way, I dig it. Keep doing what you're doing and maybe you'll sell me a bike one day.

 Would also like to know this. I made my own enduro frame from steel tubing with a small amount of machining for the linkage. That was by FAR the most expensive piece and is one of the main hurdles in making another. I am always shocked to see fully machined frames purely from a cost standpoint, although I'd love to hear how it's a better engineering solution too. Props on the frame though! Looks amazing.
  • 1 0
 As a machinist, I belive cnc rate was $120/hr end of last year for the 'small' mills, double for the very large 5-axis machine. If he's designing his own frame and cad modeling, he's done most of the programming already. If he has an in at a shop, after hours or knows the owner, it would likely be totally reasonable considering a new premium brand frame is $4500 (beaver pelts)

@ethaneggert42 absolutely awesome job! That's no small feat. Looks killer, and look forward to seeing one in the wild someday

 I'm more interested in someone explaining the kinematics... I imported that cad screenshot into Linkage and it's telling me that we've got anti-squat at about 250-650% depending what gear you're in, and a leverage ratio that starts at about 10 and reduces to about 1 at bottom out.

Now I know it's rough and inaccurate, but those are some batshit insane, unrideable numbers.

 Looks great! Sick work! But, 8 configurations! When, according to the bike media world, major manufacturers sometimes can't even nail one single configuration... I can't help but wonder if any of the configurations is really dialed, especially for what seems to be a novel suspension design.

 @ethaneggert42 - Could you share what type of bonding agent was used? I've been toying around with the idea of doing this same thing. I've been making CNC'd bike and motorcycle parts for 20 years as a hobby. I assume there were still some bolted connections to aid with strength of joining? Thanks!

 Great seeing a 19yo jump in and make things, it is quite a project. I am unsure how sustainability comes into this apart from a buzzword. Looking at this I would expect it takes about 165kgs of aluminum, so >95%scrap from CNC, compared to about 18% scrap for welded construction. The market has space for him to make these and earn a nice living. I wish him the best.

 It looks like it has an obscene amount of AS. For a bike without an idler, that is a super high pivot.
  • 2 0
 @AgrAde: I don't think the high pivot has too much too do with it. but the instant center is very high and in a weird place.
  • 1 0
 @Shtrek: yes, I was referring to the IC or virtual pivot location.
  • 2 0
 @AgrAde: ah ok. I just saw your other post about putting the design into linkage. I did the same as well after I realized the bad AS. the leverage ratio is pretty crazy and the bike is super progressive, around 280% for 70kg rider and 30% sag. At least the AR isn't bad, depending on what you prefer.
  • 1 0
 @Shtrek: I did look at the AR but can't remember... It was about 100-110% at sag wasn't it?

Makes me think that he completely forgot to consider chain forces when calculating the AS, and only took the geometry-driven AS into account. Whoops.
  • 1 0
 @AgrAde: Something like that. It seems to me like he didn't really look into suspension kinematics. But i gotta admit the frame does look really good. I think paired with a good suspension platform it would be a very sick and cool bike.

 @AgrAde: Don’t worry I did a lot of work with kinematics and definitely consider chain forces. It’s not perfect yet but so far it’s doing exactly what I want it to do. Might try testing with and O chain

 @ethaneggert42: right. How are you going to market the frame's suspension behaviour in an honest and clear way, given that "unrideable" is the word most people would use?

 Unreal design, looks so beefy. Would love to hear more about the programs and reference material required to become competent at designing a frame.
  • 2 0
 Here is some basic resources between books and software that are super useful:

Linkage Bike Checker software for suspension design

Bike Cad for designs if its simple (works best for hardtail designs)

If you want to get more complex with 3D shapes and hardware design and such Onshape and Fusion360 are both free and easy to learn. Solidworks also has a maker edition now for a pretty reasonable price.

Good resources for learning about geometry and suspension would be Vorsprungs YouTube channel. Their "tech Tuesday" series is super informative. As well as the following two books have a wealth of knowledge:

"Motorcycle Handling and Chassis Design the art and science" by Tony Foale
"Motorcycle Dynamics" by Vittore Cossalter

"Dialed" by Lee McCormack is a book about bike fit that is useful to ready through, and the "Shut up and build bikes" podcast is very informative about different small builder ideas and thoughts on bike design/manufacturing.

This frame looks sick. Back in the day it was all throw something together that looked cool. Most bikes were horrible. This bike looks awesome props to you x1000. No matter what people say it does in some computer program nothing beats riding the thing and finding out for yourself. I am interested for sure can't wait to see it finished. Ethan keep having a mind of your own don't listen to what they say you need or want do you and you will become wleverything you dreamed.
