Trailblazer AT: The 2000W Fat Enduro, Fully Loaded
The short version: This week's build is a HPC Trailblazer AT specced to the very top of every option tier — the V2 2000W motor system making 185 Nm of torque, a Rohloff E-14 electronic-shift hub paired with a Gates carbon belt drive, a 1,050Wh battery, a custom green/black two-tone finish, and 4.8″ Maxxis Minion FBF/FBR fat tires. Below, we break down each upgrade over the stock Trailblazer AT and exactly why it changes how the bike rides.
A stock Trailblazer AT is already the world's first true performance fat enduro — a carbon, full-suspension e-bike that climbs like a goat and descends like a downhill rig. This build takes that platform and maxes it out. Every box that could be checked, we checked. The result is a fat-tire enduro machine with motorcycle-grade torque, a maintenance-free drivetrain, all-day range, and a look that stops people in the parking lot.
Here's what makes this particular Trailblazer AT special — and why each choice matters once the trail points up (or down).
Spec highlights of this featured build. The stock Trailblazer AT starts at a 750W Class 1 motor and a standard drivetrain — see the full comparison below.
V2 2000W Motor System
Why it matters
The stock Trailblazer AT ships with a 750W, Class 1 motor — plenty for mellow trails. This build steps up to HPC's V2 2000W motor system, the top power tier for the platform. That's not just a bigger number: the extra headroom means the motor spends most of its life working well below its limit, so it stays cooler, holds power longer on sustained climbs, and doesn't sag when you need a surge.
For a heavier fat-tire enduro bike, that reserve is the difference between grinding up a technical climb and floating up it. More available watts also means quicker acceleration out of corners and confident passing speed on fire roads — the V2 system tops out in the 38–40 MPH range in its uncorked configuration.
2000W Power System, 185 Nm of Torque
Why it matters
Watts get the headlines, but torque is what you feel. At 185 Nm, this build produces motorcycle-class twist at the crank — the force that launches a 4.8″ fat bike up a loose 20% grade from a dead stop without a single pedal-mash of panic.
High torque at low RPM is exactly what a fat enduro bike wants. It lets you sit and spin up technical climbs in full control instead of standing and fighting for traction, and it makes the bike feel effortless under load — two-up, loaded with gear, or on a steep switchback. Paired with tuned assist levels, the 2000W system delivers that grunt smoothly and predictably rather than in an on/off punch.
Rohloff E-14 Electronic Shifting Hub
Why it matters
This is the single biggest upgrade on the bike. The Rohloff E-14 replaces a fragile external derailleur and cassette with 14 sealed gears inside the rear hub — German-engineered, effectively bomb-proof, and hidden away from rocks, mud, and derailleur strikes.
The "E" means electronic shifting: tap a paddle and the hub changes gear cleanly, even at a standstill. That's a genuine advantage on an enduro bike — roll up to a steep pitch in the wrong gear and you simply click down to your climbing ratio before you start pedaling, no coasting or soft-pedaling required. With a 526% gear range, you get a granny gear for the walls and a tall gear for the flats, all with the consistent, precise steps only an internally geared hub delivers.
For a high-torque 2000W build this pairing is ideal: an internally geared hub tolerates big power far better than a thin derailleur chain, which means less drivetrain wear and dramatically less maintenance over the life of the bike.
Gates Carbon Belt Drive
Why it matters
Feeding the Rohloff hub is a Gates Carbon Drive CDX belt in place of a traditional chain — and it's the perfect partner to an internally geared hub. A carbon belt doesn't stretch, doesn't need lube, and won't rust. There's no oily chain to blacken your leg or fling grime up the frame, and no chain to snap under 185 Nm of load.
Belts run whisper-quiet and last several times longer than a chain, often 2–3× the mileage, which is exactly what you want on a high-power bike that puts serious force through the drivetrain. Practically, that means you can hose the bike off after a muddy ride and go — the drivetrain is essentially maintenance-free. Clean, silent, and durable: it's the finishing touch that makes this build feel like a premium machine every single ride.
1,050Wh High-Capacity Battery
Why it matters
Big power is only useful if you can feed it. The stock AT starts with a 10Ah pack good for around 25 miles; this build carries a 1,050Wh battery — the largest option for the platform — for up to roughly 52 miles of range.
On a 2000W bike, range is about more than distance. A larger pack sags less under heavy current, so the motor holds its full output deeper into the ride and on long, sustained climbs. It also means you can run higher assist levels, chase a longer loop, or ride two days between charges without range anxiety. More capacity is quieter confidence: you point the bike at the mountain instead of watching the battery meter.
Green/Black Two-Tone & 4.8″ Maxxis Minions
Why it matters
Not every upgrade is about watts. This build wears a custom green/black two-tone finish — a deep gloss forest green against blacked-out components that gives the AT an unmistakable, one-of-one look. It's the detail that turns a great build into your build.
Where form meets function is the rubber: Maxxis Minion FBF/FBR 4.8″ fat tires, the front and rear pairing that defines a serious fat enduro. The FBF (Fat Bike Front) and FBR (Fat Bike Rear) are tuned for their jobs — the front bites for cornering grip, the rear digs for climbing traction and braking. At 4.8″ wide, they float over sand, snow, roots and rock, add a huge contact patch for the 2000W motor to put power down, and take the edge off big hits before the suspension even reacts. It's confidence you feel everywhere the pavement ends.

Frequently Asked Questions
What makes the Trailblazer AT a "fat enduro" e-bike?
The Trailblazer AT combines a full-suspension carbon enduro frame with 4.8″ fat tires. That pairing gives it downhill-capable geometry and suspension plus the flotation and traction of a fat bike, so it handles sand, snow, and loose technical terrain that a standard e-MTB can't. HPC bills it as the world's first true performance fat enduro.
How much range does the 1,050Wh battery give?
This build's 1,050Wh pack delivers up to roughly 52 miles of range, depending on assist level, rider weight, terrain, and how much of the 2000W power you use. Higher assist and steep climbs shorten range; lower assist and flatter terrain extend it well beyond that figure.
Why choose a Rohloff E-14 hub with a Gates belt over a normal derailleur?
An internally geared hub seals all 14 gears inside the rear hub, protecting them from impacts, mud, and wear, and it shifts electronically even at a standstill. Paired with a maintenance-free Gates carbon belt, the drivetrain handles the build's 185 Nm of torque with far less wear and virtually no upkeep — no chain lube, no derailleur adjustments, and much longer service life than a chain-and-cassette setup.
What's the difference between the stock AT and this build?
The stock Trailblazer AT starts at a 750W Class 1 motor, a 10Ah battery, and a standard drivetrain. This featured build upgrades to the V2 2000W motor system (185 Nm, 38–40 MPH), a 1,050Wh battery, a Rohloff E-14 electronic hub with Gates carbon belt drive, Maxxis Minion 4.8″ tires, and a custom green/black two-tone finish. Every one of those is a factory-available option.
Can I customize my own Trailblazer AT?
Yes. The Trailblazer AT is built to order. You choose the power level, battery capacity, drivetrain, suspension and brake package, color, and accessories in the configurator, so you can match this exact build or tailor one to your riding.
