Voxan's one-off, dry-ice-cooled land-speed special, decoded with real physics: the two-way record versus the GPS flash, where 317 kW comes from, and why this is a halo machine, not a hint at production. Sources on everything.
The fastest electric motorcycle in the world, and honest about what it is: a single-purpose record machine. It averaged 283 mph two ways in 2021, ran a 292 mph GPS peak, makes 425 hp from a Formula E powertrain, and is not for sale, not street-legal, and not rideable by you. Here is exactly what it did and how.
Why a price stack is missing here: the Wattman is a single prototype built to set records. There is no MSRP, no dealer, no out-the-door cost, and no five-year ownership story, because you cannot own one. We never invent numbers that do not exist; for this machine, the record is the whole story. Detail in §C.
Every module behind the headline: what it is, the verified record, the hardware, why you cannot live with one, and the scorecard. All sourced.
A partially streamlined land-speed missile, not a road bike. In November 2021 it averaged 455.737 km/h (283.182 mph) two ways with Max Biaggi aboard, claiming the world record for the fastest electric motorcycle, a title it still holds. It makes 425 hp (317 kW) from a 15.9 kWh Saft pack and a Mercedes-EQ Formula E powertrain, and it is cooled by dry ice rather than airflow. It is a one-off prototype: not for sale, not street-legal, not rideable by you. Here is exactly how it earned the number.
Short answer for almost everyone: no, and that is the honest point of the page.
The Wattman is a record holder kept by its makers, so "who is it for" is unusual: nobody is buying one. We frame it by who it actually serves.
The intended audience. The Wattman exists to prove how far an electric two-wheeler can be pushed when budget and engineering are unconstrained. As a proof-of-possibility machine it did its job and still holds the title.
Worth admiring as a halo. It shows what the technology can do at the extreme edge, even though none of it transfers to a bike you would ride. Read it as a flagship statement, not a buyer's guide.
There is nothing to buy. No price, no dealer network, no registration path, no production plan was announced. If you came looking for a fast electric road bike, this is not it; it is a one-off special.
It is not street-legal and is maintained by its team for flat-out runs. The dry-ice cooling alone tells you this is a racing-team solution, not something you operate yourself.
With this bike the "claim vs real" story is unusual: the headline is a real, verified record. The interesting gap is between the two-way average that counts and the GPS flash that gets quoted.
What is genuinely cutting-edge here, and what is purely a racing-team solution that will never reach a road bike.
The Wattman's hardware is serious. Each badge says whether it is a genuine engineering edge or a one-off measure you will only ever see on a record machine.
A 317 kW (425 hp) motor drawing on a Mercedes-EQ Formula E powertrain. This is top-tier electric racing hardware adapted to a two-wheeler, which is how the Wattman reaches speeds no production e-moto approaches.
★ Genuine edgeThe pack uses Saft Lithium-Ion cells, chosen for high power delivery at low weight. Saft credits the chemistry with weight and power gains that helped the bike sustain record speed without sacrificing reliability on the runs.
✓ SolidInstead of relying on airflow, the Wattman is cooled by dry ice during its flat-out runs. It is a pure racing-team fix for surviving sustained full power, and a clear sign this is a special, not a product.
★ Genuine edge (race-only)The body is partially streamlined, which is also why it competes in a specific FIM class ("partially streamlined, under 300 kg"). The class definition matters: it is how the record is categorized and compared fairly.
✓ SolidThe headline speed is a two-way average over a flying kilometer, run in opposite directions within two hours, per FIM rules. That method cancels wind and slope, which is what makes it a legitimate record rather than a one-way flash.
★ The honest way to claim itThe math behind the record. The two numbers that get conflated, and the power conversion everyone should run.
Peak kilowatts make a great headline. Convert to the unit everyone feels, and the figure is honest: this really is a 400-plus horsepower motorcycle.
This is the one number people get wrong. The two figures are both real, but only one is the record, and they measure different things.
The record is 455.737 km/h (283.182 mph). Under FIM rules it is a two-way average over a flying kilometer, run in opposite directions within two hours. Averaging both directions cancels any tailwind or downhill help, which is what makes it count.
The 470 km/h GPS reading is the highest instantaneous speed the on-board speedometer logged in a single direction. It is genuinely impressive, but it is not the record, because it was not averaged both ways. We keep them separate so a one-way flash never gets quoted as the official result.
On most reports this is where we derive real range and charge time. For a land-speed special, those formulas are the wrong tool, and inventing numbers would break our one rule.
The Wattman has a 15.9 kWh pack, but no manufacturer range claim, no nominal voltage and amp-hour split, and no stock charger wattage are published for a bike that was never sold to ride. It is built to empty itself at maximum power over a measured kilometer, not to commute. So we do not estimate a "real-world range" or a "charge time" here: there is no honest consumption figure for a record run, and we never guess.
There is no price, and we will not invent one. Here is why, stated plainly.
A full out-the-door and five-year breakdown is not possible for this model, because it was never offered for sale.
The Voxan Wattman is a single prototype built and maintained by its team. No MSRP, freight, tax, or five-year ownership figure exists for it, so there is no out-the-door table and no cost-to-own stack to show. Producing one would mean inventing numbers, which we never do. The cost that actually defined this project was a record-program budget at the maker, and that figure is not public.
You cannot, and that is the honest answer.
There is no owner community to summarize, because there are no owners. We report what is verifiable about the machine instead.
A bike is only as ownable as its parts supply. Here there is effectively none, because the Wattman is a single machine.
There is no aftermarket and no consumer parts channel for the Wattman. It is maintained by its own team with bespoke, race-program components. This is the opposite of a mass-market platform: nothing about it is designed to be serviced or upgraded by an owner.
| Part category | Availability | Notes |
|---|---|---|
| OEM consumer parts | none | One-off prototype |
| Aftermarket upgrades | none | No platform to build on |
| Dealer service | none | Maintained by its team |
One scorecard, identical axes on every bike, even one you cannot buy.
We score every machine on the same eight axes by the same rules. For a record one-off, most "ownership" axes score low by design; that is the honest reflection of what it is, not a knock on the engineering.
Our standing methodology, run identically on every e-moto. For this record one-off we use only the formulas that have honest inputs.
The honest way to compare batteries. The Wattman's pack is 15.9 kWh; the V and Ah split is not published, so we do not derive it.
You never use 0 to 100%. A BMS holds a reserve and voltage tapers. Not applied here, because there is no published range to derive.
Consumption is the lever, and it rises with speed squared. A land-speed run has no meaningful "range" figure, so we leave it blank.
317000 ÷ 746 = 425 hp, which matches the maker's figure. On a record run, peak power is exactly what is used.
"Fast charging" means nothing without the charger's wattage. No stock charger spec is published for the Wattman, so we do not estimate a time.
| Cost assumption | We used | Change it if… |
|---|---|---|
| Annual mileage | n/a, not a road bike | There is no ownership case to model |
| Electricity rate | $0.17 / kWh (US avg) | Not applied, no range or use case |
| Sales tax | ~8% | No retail price to tax |
| Battery life | n/a | Team-maintained prototype |
| Resale | n/a | Never offered for sale |
We cite everything and date it, because specs and records get misquoted. Manufacturer figures are labeled as claims; the record figures are FIM-verified results, kept separate from the one-way GPS peak. Spot an error? Our corrections policy means we fix it in public.
Sources retrieved May 2026. The record (283 mph two-way average) is an FIM-verified result; the 292 mph figure is a one-way GPS peak and is not the record. The Wattman is a one-off prototype with no price, no production plan, and no parts supply; we state that rather than estimate ownership figures.
