I've now thoroughly reviewed both PDFs. Let me give you a clear summary.
Yes, both USB charging and battery protection are already covered in your battery architecture — they're part of the self-contained battery pack design you've been developing. Here's the breakdown:
The battery pack includes a full USB-C PD charging system built into the electronics bay at the bottom of the scaffold: [ppl-ai-file-upload.s3.amazonaws](https://ppl-ai-file-upload.s3.amazonaws.com/web/direct-files/attachments/139085844/034f9600-ef48-4131-a73d-2b01ba0dbb3c/battery-bike.pdf?AWSAccessKeyId=ASIA2F3EMEYERY5HOSGV&Signature=JgABIWblZW1FlfgqIHao4y8FOZ0%3D&x-amz-security-token=IQoJb3JpZ2luX2VjENn%2F%2F%2F%2F%2F%2F%2F%2F%2F%2FwEaCXVzLWVhc3QtMSJIMEYCIQCgnjY6IyRbvPPuTLrMDmePKA8eVfe3Wphw98YV44f40AIhAIC3sX49jELv1e1IUSZhEHZBWMIGpf4zip4GI9fnNuXsKvwECKL%2F%2F%2F%2F%2F%2F%2F%2F%2F%2FwEQARoMNjk5NzUzMzA5NzA1IgxSlv5mMW3VgEeWYQ0q0AQme1trLWTjmqRM5ZlrdIS5k90hb6bm
can you give me direct links to the product pages of the solution you suggest: Anderson SBS75X — best feature overlap (finger-proof, power + signal, flat-wipe self-cleaning contacts), widely available including from RS in Norway, but mates horizontally and isn't sealed CHOGORI FC09 Pro — closest application match (e-scooter battery swap, blind mate, IPX7, 40A+5A), but uses conventional pin/socket rather than interleaving fins Amphenol BSC — most configurable (modular power + signal inserts, IP2X finger-proof, optional IP67 shroud), but oversized for a 10A ebike-scale application
Here's a cartoon meme concept:
Panel 1: A circle of concerned-looking characters (a Period, a Comma, a Semicolon, and a Colon) sit in folding chairs facing an AI robot who's slouched in a chair, arms crossed defensively.
Panel 2: The Period stands up, reading from a letter: "We love you, AI… but you used 38 em dashes in a single paragraph. It's time to get help."
There's a lot of potential here, especially since you're already building custom firmware/controller logic and have deep experience with local AI. The torque sensor gives you a real-time force signal at ~100–200 Hz — that's a rich data stream most e-bike brands barely use beyond simple proportional assist. adventuro
Run a lightweight model (TinyML / TFLite on the controller MCU, or on a companion ESP32) that learns your pedaling signature over time: tamobykesport
- Builds a personal torque-cadence-speed profile across different terrains and conditions.
- Automatically adjusts the assist curve without you touching PAS levels — it just knows you want more on climbs and less on flats.
- Could run entirely offline, fits Omera's local-first philosophy. [adventuro](https://adventuro.com/how-
Omera’s ethos is: a real fixed‑gear that just happens to be electric, not an e‑bike pretending to be a fixie. lunacycle
- Stealth first. All electronics are hidden: battery in the down tube, controller inside the frame, almost all cables internal, hub motor that reads like a flip‑flop hub. From a few meters away it should pass as a clean track bike, not an e‑bike. newatlas
- Fixie ride feel, lightly augmented. Geometry, belt, and torque sensor are tuned so it rides like a good brakey street track bike; the motor just adds legs, not a scooter feel. Think “slightly superhuman rider,” not moped. velotricbike
- Mechanical honesty. Simple, serviceable aluminum frame, standard parts (BSA BB torque sensor, Gates belt, 36V hub system) that any competent shop can understand. No glued‑in proprietary batt
Here's a comprehensive overview of ebike battery designs — especially relevant for your Omera frame project.
The industry has largely moved to 21700 cells for new builds. They're 50% larger in volume than 18650s but pack up to 45% more energy density, meaning more range with fewer cells and better heat management. em3ev
| Spec | 18650 | 21700 |
|---|---|---|
| Diameter | 18mm | 21mm |
| Height | 65mm | 70mm |
| Max capacity | ~3,500 mAh | ~5,000 mAh |
| Weight | ~48g | ~70g |
| Best for | Compact builds, legacy packs | New builds, higher range batterydesign |
That's a smart move. The Detroit is the spiritual reference, but the Omera needs its own visual identity. A seat tube cutout is a strong signature — instantly recognizable and signals "this is a track-bred frame" without copying Dosnoventa's exact look.
| Feature | Detroit | Omera |
|---|---|---|
| Seat tube | Standard round | Cutout wrapping rear wheel ✅ |
| Down tube | Columbus Airplane ovalized | 50mm round (battery inside) |
| Drive | Chain | Gates CDX belt (visible difference) |
| Brakes | None (track) or rim | Hydraulic disc |

That's a great workflow — OpenSCAD is code-based, so you just describe what you want and I write the script. Perfect for parametric bike frame geometry where everything is defined by numbers.
But there's actually an even better option for your needs: CadQuery — it's a Python CAD library that works the same way (you prompt, I code) but exports STEP files directly, which factories prefer over OpenSCAD's STL. cadexchanger
