A six-figure British carbon-fibre electric sportbike, genuinely brilliant engineering and a cautionary tale at the same time. We decode the torque headline, run the energy math, and explain why the real ownership risk is not a part, it is a failed company. Sources on everything.
One of the most ambitious electric motorcycles ever attempted, and the market punished that ambition twice. The carbon monocoque is real, clever engineering. But Arc went bankrupt in 2019 and again in 2024, only about 11 bikes reached customers, and there is no factory support left. This is a collector's curiosity, not a motorcycle you buy to ride for a decade.
What we know, and don't: the purchase price is six figures and varied by market and configuration. Beyond that, insurance, specialist servicing, and any repair on a defunct platform are unpredictable, so we mark them "unquantifiable" rather than invent a number. This is a collector's object, priced like one. Methodology in §8.
Every module behind the headlines: who it is for, the torque number decoded, the real ownership risk, true cost, and the standard scorecard. All sourced.
An ultra-premium electric sportbike from Coventry, England, built around a carbon-fibre monocoque where the 16.8 kWh battery is itself a structural part of the frame. Gorgeous, genuinely clever, and effectively rolling art at around $117,500. It is also a cautionary tale: Arc filed for bankruptcy twice (2019 and 2024), only about 11 bikes were delivered, and there is no factory support today. Admire it, study it, but go in clear-eyed: you are buying an orphan. Here is the full picture.
Start here, and for this bike the honest answer is "almost certainly not, unless you are a collector".
Same bike, very different answer depending on the buyer. We lead every report with this so nobody buys the wrong machine, and this one has a very narrow right buyer.
The right buyer, and almost the only one. A remarkable story, exotic engineering, and genuine rarity (about 11 delivered) make this a compelling conversation piece for someone who already owns several normal motorcycles.
The carbon monocoque, with the battery as a stressed member, and the hub-centre front end are exotic in the best way. As an object to study and admire, it is extraordinary.
If you want something to actually ride and keep running for a decade, look almost anywhere else. No factory support, bespoke parts, and no meaningful service network make this impractical as a usable vehicle.
At six figures with no support, there is no value case. Far quicker, far cheaper, fully supported electric sportbikes exist. Buy this only for what it is, not for what it does per dollar.
Same bike, two stories. The headline specs are genuinely impressive; the catch is not in the numbers, it is in the company behind them. The "why" is in Parts C and E.
What is genuinely brilliant, and which "innovations" were headline-grabbing gloss. The Vector has both, in large measure.
The features that matter, rated honestly. Some of the Vector's engineering is genuinely class-leading; some of the show was always more press release than purpose.
The real story. The 16.8 kWh battery is itself a structural element of the frame, which keeps the whole bike light for the class (~485 lb) and is genuinely advanced engineering. This is what makes the Vector matter.
★ Genuine edgeA ~105 kW motor, a claimed 3.1 second 0 to 60 mph, and an electronically limited ~124 mph (200 km/h). Genuinely fast, with strong torque available from the first crack of the throttle.
✓ SolidAn exotic alternative to a conventional fork, in keeping with the bike's no-compromise design brief. Rare, sophisticated, and part of why it rides as smoothly as reviewers describe.
✓ SolidA heads-up helmet that feeds you data and a suit that buzzes to warn you. These grabbed press coverage but mostly added cost and complexity to a bike that did not need help being expensive.
⚠ OversoldMarketing specs vs. the physics. The standout here is the torque number, which is true but not quite what it sounds.
Arc loved to quote a huge torque figure that read like a Tesla rivalry. That number is real, but it is measured at the wheel after gearing, not at the motor. The difference matters.
The headline figure was 397 Nm at the output sprocket, achieved through internal gearing. 397 Nm of motor torque. Per MCN and Wikipedia, the actual motor output is closer to 85 Nm (about 63 lb-ft):
The Vector carries a genuinely large 16.8 kWh pack for a motorcycle, so the range claim is plausible, but like every bike it falls at speed. Here is the energy math.
Step 1, energy in the battery. The pack is a 16.8 kWh Samsung-cell unit. Arc does not publish a simple V and Ah split in our sources, so we use the stated kWh rather than invent the numbers:
Step 2, how far that goes. Sources cite up to ~168 mi mixed and around ~120 mi at highway speed. Back out the implied consumption:
Charge time is just battery size divided by charger power. Arc claimed a fast figure, but with so few bikes in the wild it is not widely verified.
Arc claimed roughly 30 minutes on a fast charger, with sources also citing about 0 to 80% in ~45 minutes on a fast charger and around 4 hours on a standard charger. Run the formula to see what wattage that 4-hour standard charge implies:
The sticker is six figures, but the real cost is risk. Here is what we can verify, and what we will not pretend to know.
A normal out-the-door table does not capture this bike. The purchase price is the knowable part; everything after it is shaped by a defunct manufacturer.
| Line item | Typical | Notes |
|---|---|---|
| Purchase (approx) | ~$117,500 | Quoted $111k–$130k across markets and time; six figures |
| Insurance | unquantifiable | A rare, defunct-make six-figure EV; specialist underwriting, varies widely |
| Servicing | unquantifiable | No factory network; bespoke electronics need a specialist who can find one |
| Major repair | impractical | Bespoke carbon and electronics, no surviving parts supply |
| Resale | collector-driven | Value is rarity-based, not depreciation curves; thin, unpredictable market |
| Realistic ownership cost | six figures + risk | Dominated by the failed company, not running costs |
The hardest part of the report, and the most important: there is almost no support network behind this bike.
Too few units sold to establish a reliability record. The dominant ownership risk is the defunct manufacturer, and we report it plainly.
One scorecard, identical axes on every bike.
Every e-moto on the site is scored on these same eight axes, by the same rules, so a 1 here means the same thing as a 1 anywhere. The Vector scores brilliantly on engineering and terribly on everything ownership.
Our standing methodology, run identically on every e-moto, including bikes we would otherwise have reason to flatter.
The only honest way to compare batteries. Arc does not publish a simple V/Ah split here, so we use the stated 16.8 kWh.
You never use 0 to 100%. The BMS holds a reserve and voltage tapers at the bottom. We assume ~88%.
Consumption is the lever: ~88 Wh/mi mixed here, more at highway speed. Drag rises with speed².
Also ask where torque is measured. Arc's 397 Nm is at the wheel after gearing; the motor makes ~85 Nm.
"Fast charging" is meaningless without the charger's wattage. Arc's 30-minute claim implies DC fast charging.
| Cost assumption | We used | Change it if… |
|---|---|---|
| Annual mileage | 1,500 mi/yr (7,500 / 5 yr) | A collector may ride far less |
| Electricity rate | $0.17 / kWh (US avg) | Your utility differs |
| Sales tax | ~8% | Your state or country differs |
| Battery life | Unknowable on this platform | No support to replace it through |
| Resale | Collector-driven, not modeled | Rarity, not depreciation, sets the price |
We cite everything and date it, because specs, prices and corporate status change. Manufacturer figures are labeled as claims; real-world numbers are our estimates from the methodology above. Spot an error? Our corrections policy means we fix it in public.
Sources retrieved June 2026. Manufacturer figures are claims, not independent tests, and with so few units delivered, real-world data is limited. The company's defunct status is the single most important fact for any prospective owner; confirm current status before acting.
