Trailblazer Pro Build: 2000W, Rohloff Belt Drive & DVO Prime Coil
The short version: This custom HPC Trailblazer Pro takes our full-carbon enduro platform and adds eight upgrades over stock: the V2 2000W motor (190 Nm), a Rohloff E-14 electronic hub driven by a Gates carbon belt, a 1,050Wh battery, the new 2027 DVO Onyx 38 Prime fork, a DVO Jade X Prime coil shock, an Ergon saddle, and an integrated lighting system. The result is a quiet, low-maintenance, all-day trail bike with motorcycle-level torque and coil-sprung traction. Here's what each upgrade does and why it's worth it.
A stock Trailblazer Pro already rolls on pro-level parts: a full-carbon frame with 155mm of travel, Magura MT7 four-piston brakes, e*thirteen carbon wheels, and Continental Kryptotal DH tires. This build keeps all of that and changes the parts you feel on every ride: how it puts down power, how it shifts, how long it lasts, and how it handles rough ground.
The theme is set it up once and ride. Belt drive instead of a chain, sealed gears instead of a derailleur, coil instead of air, and lights that run off the main battery. It's a high-performance enduro e-bike that asks very little of you between rides.
Stock 2027 Trailblazer Pro: 750W motor (100 Nm), 10Ah battery, SRAM X0 Transmission, DVO Onyx 38 fork with Topaz Prime air shock, WTB saddle, no lights. Full comparison below.
V2 2000W Motor System
Why it matters
The stock Pro ships with a 750W motor making 100 Nm. This build runs HPC's V2 2000W system, built on the Bafang M560 V2 with our own controller and firmware. It makes 190 Nm of torque, nearly double the stock motor, and the new magnesium housing is about 1.1 lb lighter than before.
That torque is what changes the ride. You can stay seated and spin up steep, loose climbs that would stall a 750W bike, and it pulls hard out of every corner. Because the motor has so much headroom, it isn't working at its limit, so it runs cooler and doesn't fade on long climbs. In its off-road setting it reaches 40+ MPH. See the full torque and power curves.
Rohloff E-14 Electronic Hub
Why it matters
Stock, the Pro uses a SRAM X0 Transmission, which is a great derailleur system. This build replaces it with a Rohloff E-14: 14 gears sealed inside the rear hub, made in Germany, with a 526% range from a low climbing gear to a tall top gear.
The E-14 shifts electronically from a paddle on the bar, and it shifts while you're stopped. If you stop on a steep pitch in a high gear, you tap down before you pedal off. There's no derailleur hanging under the bike to hit rocks, and no cassette to wear out. At 190 Nm, that durability matters more than ever: a sealed hub handles big torque much better than a thin chain and cassette, so you spend far less on drivetrain parts over the life of the bike.
Gates Carbon Belt Drive
Why it matters
A Gates Carbon Drive CDX belt carries power from the motor to the Rohloff hub. A belt doesn't stretch, never needs lube, and won't rust. There's no greasy chain to clean or snap, and it typically lasts two to three times as long as a chain.
It's also almost silent. Combined with the sealed Rohloff, the drivetrain makes so little noise that you mostly hear your tires. After a muddy ride you rinse it off and you're done. We break down this pairing in more detail in our Rohloff E-14 + Gates belt explainer.
1,050Wh Battery
Why it matters
The stock Pro starts with a 10Ah pack. This build carries the 52V 20.25Ah Extreme Performance battery, about 1,050Wh and the largest pack the Trailblazer takes, good for up to roughly 52 miles depending on how you ride.
On a 2000W bike, a bigger battery does more than add miles. It holds its voltage better under heavy load, so the motor keeps its full power later into the ride and on long climbs. It also powers the lights on this build, so you're not carrying or charging a second battery.
2027 DVO Onyx 38 Prime Fork
Why it matters
The stock Pro already uses a DVO Onyx 38. This build steps up to the new 2027 Onyx 38 Prime, which adds DVO's new Prime damper. It replaces the old bladder with a spring-backed internal floating piston, uses a higher-flow piston, and has lower-friction internal finishes.
On the trail, that means more support when you push hard into a berm or land a drop, and a smoother feel over small bumps. It has separate high- and low-speed compression adjustment, so you can tune it to your weight and terrain. The 38mm stanchions keep the front end stiff and accurate on a fast, heavy e-bike.
DVO Jade X Prime Coil Shock
Why it matters
The stock Pro uses DVO's Topaz Prime air shock. This build switches to the Jade X Prime coil. A coil spring feels the same at the bottom of a long descent as it does at the top, because there's no air to heat up. It's also very smooth off the top, so the rear tire stays in contact with the ground over roots and rocks. That gives you more traction for both climbing and braking.
The Prime version adds a piggyback compression circuit with a new piston and shim stack, tool-free high- and low-speed compression dials, a rebound dial you can turn with gloves on, and updated bushings for a smoother stroke. A heavy, powerful e-bike is where a well-tuned coil makes the biggest difference.
Ergon Saddle
Why it matters
The stock WTB saddle is light and race-focused. This build uses an Ergon saddle, shaped to support your sit bones and take pressure off soft tissue.
That matters more on an e-bike than you might think. With 190 Nm of help, you spend much more time seated, climbing and covering long distances. A better saddle means less numbness and fatigue, and you can ride longer. On a bike with a 52-mile battery, the saddle is often what decides how long the ride lasts.
Integrated Lighting System
Why it matters
The stock Pro doesn't come with lights. This build has a front headlight and a rear taillight wired into the main battery, so there are no separate batteries to charge or forget.
That makes early-morning and evening rides easy, and it helps you be seen on fire roads, bike paths, and the ride to the trailhead. On a bike this fast, being visible is a real safety feature, not a nice-to-have.

Frequently Asked Questions
What upgrades does this Trailblazer Pro have over stock?
Eight: a V2 2000W motor with 190 Nm of torque (stock is 750W), a Rohloff E-14 electronic hub (stock is SRAM X0 Transmission), a Gates carbon belt instead of a chain, a 1,050Wh battery (stock is 10Ah), a 2027 DVO Onyx 38 Prime fork, a DVO Jade X Prime coil shock (stock is a Topaz Prime air shock), an Ergon saddle, and integrated front and rear lights.
Is a coil shock better than an air shock on an e-bike?
For many riders, yes. A coil spring stays consistent on long descents because there's no air to heat up, and it's very smooth over small bumps, which helps traction. E-bikes are heavy and spend a lot of time on rough ground, which suits a coil. An air shock is lighter and easier to adjust for rider weight, which is why the stock Pro uses one.
Why a Rohloff E-14 and belt instead of a derailleur?
The Rohloff E-14 seals 14 gears inside the hub, shifts electronically even when you're stopped, and has no derailleur to damage. The Gates belt needs no lube and lasts much longer than a chain. Together they handle 190 Nm of torque with very little wear or maintenance, and they're almost silent.
How far can it go on one charge?
Up to roughly 52 miles with the 1,050Wh battery. Actual range depends on assist level, speed, terrain, and rider weight. Riding hard at full power uses more battery; lower assist goes farther.
How much does a Trailblazer Pro cost?
The 2027 Trailblazer Pro starts at $13,000 and is built to order. Upgrades like the 2000W motor, larger battery, Rohloff belt drive, and suspension options are added in the configurator.
