The Arctic Leopard / Vetra brake upgrade guide is live on the VoltHaus blog.

If you have tried to sort out a brake upgrade for one of these bikes, you already know the usual advice is much simpler than the actual job. "Just get Ultra Bee brakes" skips the rotors, brackets, bolt patterns, hose fittings, clearance checks, and all the other details that decide whether the parts really work together.

We put together the guide Cory wishes had existed before he started. It covers:

- what the stock brakes do well and what to service before replacing anything
- rotor diameter, thickness, bolt patterns, and front/rear differences
- why the bracket is the part that makes or breaks the conversion
- single versus dual rear brackets, including future foot-brake options
- the supported E-Bike Garage route versus the lower-cost FMO/AliExpress route
- the spoke-clearance issue that led to machining Cory's front caliper
- the exact parts, spares, and ordering mistakes from this build

The stock brakes can work. The upgrade path is real too. The confusing part is knowing what matches your bike and how much verification work comes with each option.

Part 2 will get into the physical install, measurements, clearance, bleeding, and ride testing. Questions and corrections are welcome; the goal is to make this easier for the next Arctic Leopard or Vetra owner.

"Just get Ultra Bee brakes" is not an answer. A hands-on Arctic Leopard / Vetra brake upgrade guide covering stock brakes, rotor compatibility, brackets, no-logo kits, and what Cory ordered.

The 2026 Clouded Leopard XE Pro Series lineup is now laid out, and we put together a rider-focused breakdown of what changed, what appears to carry over, and how the trims compare.

We cover:
- XE Pro S updates
- XE L1E-B
- XE Pro S Enduro
- XE Pro S Super
- XE Pro R

Display, battery, suspension, brake, and compatibility notes
what existing XE Pro S owners should still double-check.
We tried to frame it around the practical questions riders are actually asking: which trim is which, what changed for 2026, what still needs proof in real-world riding, and what should not be assumed before buying or upgrading.

More Arctic Leopard / Clouded Leopard notes coming as we keep digging into display compatibility, battery reports, Pro R differences, and the new suspension options.

Arctic Leopard has presented its 2026 Clouded Leopard XE Pro series lineup: Pro S, L1E-B, Enduro, Super, and Pro R. What changed, what is shared, and what current owners should check before upgrading.

We just published the first VoltHaus blog post.

This one is an honest introduction to who VoltHaus Labs is, why we started building parts for the Arctic Leopard / Vetra ecosystem, and how the blog will support riders with knowledge, not just products.

The goal is practical: clearer install notes, compatibility questions, upgrade guidance, and real process from the shop.

Connect to the module’s Wi‑Fi hotspot, open the browser page, and tune exactly how you want your signals to behave:

• Blink timing (on/off)
• Pulses per press
• Hazard hold time
• Brightness
• Color tuning (idle / left / right / hazard / regen active)

Hit Save to device and you’re done. Built to adapt to your bike + whatever other hardware you’re running.

If you want in on the first test batch, comment your bike model + year.

Appreciate all the interest on the last post — awesome to see how many riders want proper signals on these bikes.

Quick demo of the VoltHaus signal kit in action.

• Left signal
• Right signal
• Hazard mode
• Regen Enable

Everything is running on our current prototype hardware and working exactly how we hoped. Now we’re finishing up a few things before the community test batch:

If you commented “TESTER” on the last post, we’ll be reaching out soon with details for the small community testing group.

Target bikes remain:
Arctic Leopard XE Pro + Vetra Blazer

More updates coming soon!

The VoltHaus PNP Tail Harness v1.0 is officially live!

Thanks to everyone who has followed the development, offered feedback, and waited patiently while this came together. The extra time spent refining the design was absolutely worth it, and I’m excited to finally make it available.

The VoltHaus PNP Tail Harness adds tail light and brake light functionality, a handlebar-mounted regen button, and forward compatibility for future left/right signaling controls. It installs using OEM connectors and existing mounting points—no cutting, soldering, or drilling required, and fully reversible.

For those riding the Arctic Leopard XE Pro / Pro S or Vetra Blazer, this should be a clean, OEM-friendly way to upgrade your lighting and control setup.

Product page and ordering details are now live here:

Thanks again for the support. Looking forward to seeing these out in the wild.

Tail Light Breakdown

Here is new video walking through the full tail light assembly — what’s inside, how it connects, and how it all works with the new VoltHaus PNP Tail Harness V1.

This has been a big focus the past few weeks, and I’m really happy with how it’s coming together.

The harness now supports brake light functionality and is forward-compatible with upcoming signalling cockpit controls (turn signals, hazard, etc.).

I’ll be doing a limited pre-production run available exclusively to members of this group first before public release — so stay tuned for details and pricing soon.

Thanks again for all your patience and feedback — this project keeps getting better because of the community here.

Update from the Lab

Thanks to everyone who's been following along and offering feedback — it's made a real difference. One of the most requested features was brake light functionality, and I'm happy to say: it's here.

Our plug-and-play tail light harness for the Arctic Leopard XE Pro S and Vetra Blazer just got smarter:

✅ Integrated brake light function
✅ Forward-compatible with future cockpit signalling (left/right indicators, etc.)

The video below walks through the updated harness in action, including the tail light assemblies installed on the bike. A full breakdown of each component is coming soon, followed by pricing and ordering info — very shortly.

Appreciate everyone’s patience. I took a bit more time to ensure these upgrades met the high expectations you've helped set.
