Voxan Wattman · the honest report

The 283 mph record,
and the bike you cannot buy.

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.

Start with what matters
The 10-second answer

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.

What actually happened

Two runs, two hours,
one average.

0455.737 km/h, the two-way FIM record
Between November 18 and 23, 2021, Max Biaggi and the Voxan Wattman set 21 world records at Space Florida's Launch and Landing Facility at the Kennedy Space Center. The headline figure, 455.737 km/h (283.182 mph), is the class record for a partially streamlined electric motorcycle under 300 kg. A GPS speedometer logged a peak of 470.257 km/h (about 292 mph) during the runs.

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.

The full report

Every module behind the headline: what it is, the verified record, the hardware, why you cannot live with one, and the scorecard. All sourced.

The 10-second honest answer

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.

A

Is this bike for me?

Short answer for almost everyone: no, and that is the honest point of the page.

01

Who it is actually for

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.

🏆Record chasers and engineers

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.

Verdict, exactly what it is for
📚EV enthusiasts and the curious

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.

Verdict, admire from afar
💰Buyers and commuters

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.

Verdict, not purchasable
Anyone planning to ride one

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.

Verdict, unrideable by you
02

At a glance: claim vs. record

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.

Innovations

What is genuinely cutting-edge here, and what is purely a racing-team solution that will never reach a road bike.

03

What makes it special

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.

Formula E-derived powertrain

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 edge
🔋15.9 kWh Saft battery

The 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.

✓ Solid
Dry-ice cooling

Instead 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)
🗻Partial streamlining

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.

✓ Solid
🏁FIM two-way record method

The 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 it
Why this beats the brand's own page: a manufacturer page leads with the biggest single number. We separate them for you: the 283 mph two-way average is the record, the 292 mph GPS reading is a one-way instantaneous flash, and the dry-ice cooling is a race-only measure, not a feature you would ever get. That is what is actually remarkable, and what is just headline.

Keeping them honest

The math behind the record. The two numbers that get conflated, and the power conversion everyone should run.

04

The "317 kW" headline, decoded

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.

# Horsepower = Watts ÷ 746
Quoted output:  317000 W ÷ 746 = 425 hp  (matches the 425 hp the maker states)
Voxan Wattman
425 hp · 317 kW
A fast production e-moto
~85 hp typical
Why it matters: on a road bike the question is always "continuous or peak," because heat rolls peak back. On a land-speed run that distinction matters less: the bike makes a short, maximal effort over a flying kilometer, which is exactly the kind of burst a peak figure describes. The torque is quoted in four figures (about 1,003 lb-ft), which is what launches a streamlined machine toward 283 mph.
05

283 mph vs. 292 mph: which is the record?

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.

# FIM record = average of two opposite runs over a flying km
Two-way average:  455.737 km/h = 283.182 mph  (the verified record)
GPS peak (one-way flash):  470.257 km/h ≈ 292 mph  (instantaneous, not averaged)

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.

The takeaway: when you see "292 mph" attached to the Wattman, it is the GPS peak, not the title. The world record, the one that still stands, is the 283 mph two-way average.
06

The range and charging math we are not running

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.

⚠ What we will not fabricate We have the battery size (15.9 kWh) and the motor power (317 kW), but not the V and Ah split, a claimed range, or a charger spec. Rather than fill those with plausible-sounding numbers, we leave them blank. For this machine the meaningful figure is the record, and that one is fully sourced.
D

What it costs

There is no price, and we will not invent one. Here is why, stated plainly.

07

Cost to buy and own

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.

Our position: when a model has no real price, we say so rather than estimating. A full five-year breakdown for this machine does not exist and cannot be itemized honestly, so we leave it blank. If a production Voxan road bike is ever announced with a real price, it would get its own report with a real cost stack.
E

Living with it

You cannot, and that is the honest answer.

 
08

Service, reliability, and ownership reality

There is no owner community to summarize, because there are no owners. We report what is verifiable about the machine instead.

✓ What is genuinely strong

  • Set 21 world records over a single November 2021 campaign, a sign of a well-prepared, repeatable machine.
  • Saft credits its cells with reliability across the record runs, not just peak power.
  • Race-grade engineering throughout, drawing on a Mercedes-EQ Formula E powertrain.
  • Still holds the title years later, which speaks to how far ahead the program built.

✕ Why you cannot live with one

  • One-off prototype: no aftermarket, no dealer network, no spare-parts supply.
  • Not street-legal and has no registration path; it is a closed-course record machine.
  • Dry-ice cooling and team maintenance mean you do not simply operate it.
  • Not for sale at any price, so ownership is moot.
⚠ Street-legal status The Wattman is a purpose-built land-speed special, not a road-going motorcycle. It is not street-legal and was never homologated for sale. Anything you read about registering, insuring, or commuting on one does not apply.
09

Parts & aftermarket availability

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.

The verdict

One scorecard, identical axes on every bike, even one you cannot buy.

10

The standard scorecard

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.

Bottom line: judged as a consumer motorcycle the Wattman scores low almost everywhere, and that is the point: it was never meant to be one. Judged as what it is, a record machine, it is genuinely remarkable and still the fastest electric motorcycle in the world. Admire the numbers, run the two-way average rather than the GPS flash, and do not expect a road-going version.

The math toolkit

Our standing methodology, run identically on every e-moto. For this record one-off we use only the formulas that have honest inputs.

5 formulas, every bike
1Real energy in the battery
Energy (Wh) = Voltage (V) × Capacity (Ah)

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.

2Usable energy
Usable Wh ≈ Nominal Wh × 0.85–0.90

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.

3Real range
Range (mi) = Usable Wh ÷ Consumption (Wh/mi)

Consumption is the lever, and it rises with speed squared. A land-speed run has no meaningful "range" figure, so we leave it blank.

4Power you can feel
hp = Watts ÷ 746  |  Continuous = cruise · Peak = launch

317000 ÷ 746 = 425 hp, which matches the maker's figure. On a record run, peak power is exactly what is used.

5Charge time
Time (hr) ≈ Battery Wh ÷ Charger W × 1.1

"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.
