A fast, light, sharply styled British step-through built on a carbon-look Exoskeleton frame. Quick off the line and unmistakable to look at, but short-legged. Decoded here with real physics: where the small battery's range goes, peak versus continuous power, what it truly costs, and who it is for. Sources on everything.
A style-and-performance toy for the city, not a long-haul commuter. Plan for ~30 real miles (the 37 mi figure is the eco best case from a small 2.5 kWh pack), strong acceleration from a ~19 hp peak motor, a genuine 60 mph top speed, and ~$7,000 net to own over 5 years. Big on punch and looks, weak on distance.
Assumptions: ~2,000 city mi/yr, $0.17/kWh, no battery replacement in 5 years, ~40% resale (small-volume brand, uncertain), moped/scooter-class insurance. UK pricing converted to USD. Full table in §10.
Every module behind the headlines: who it is for, claims vs. physics, true cost, reliability, parts, and the standard scorecard. All sourced.
A high-performance urban step-through built around a distinctive Z-shaped Exoskeleton frame. It is quick, it is light (~90 kg), and it is unmistakable. The trade is range: a small 2.5 kWh pack keeps it sharp but short-legged. Plan for ~30 real miles (the 37 mi figure is the gentle eco best case), a genuine 60 mph top speed, and ~$7,000 net to own over 5 years. Think of it as a style-and-performance toy for the city, not a long-haul commuter. On those terms it is good. On range, it is not. Here is the math.
Start here, the right answer depends entirely on who is asking.
Same bike, very different answer depending on the rider and the route. We lead every report with this so nobody buys the wrong machine.
The sweet spot. If your runs are short, fast, and inside about 30 miles, the i300 is a genuine thrill: light, eager, and head-turning. Carry-in charging suits apartment life.
The patent-pending Exoskeleton frame is genuinely distinctive, and reviewers consistently praise the looks and handling. If you want a bike that stands out, this one does.
The wrong tool. A small 2.5 kWh pack and a performance focus mean real range lands near 30 miles. If your day involves real distance, you will charge more than you ride.
Zapp is a small-volume UK startup with a limited service footprint and minimal aftermarket. If a deep dealer network matters to you, weigh that carefully before signing.
The struck-through line is what the listing tells you; the big number is what to actually expect. The "why" is in Part C.
What is genuinely clever, and which "innovations" are really table-stakes. The part the brand's own page never tells you.
The i300's case rests on its frame and its punch. Each badge tells you whether it is a real engineering edge, normal for 2026, or marketing gloss.
The patent-pending structural design is genuinely distinctive and central to the bike's low weight and looks. It is the reason a step-through can weigh ~90 kg and still feel rigid and sharp. The real headline here.
★ Genuine edgeTwo 72V packs at ~6 kg each pull out for carry-in charging, a real practical advantage for urban riders who park where they cannot run a cable. You can also run on a single pack. Well executed, though increasingly common among rivals.
✓ SolidAn interior permanent magnet motor delivers eager, motorcycle-flavored launch uncommon in a step-through, reaching ~50 km/h in the low-2-second range. The fun is real, and it is the i300's best on-road trait.
✓ SolidRecovers a little energy on slowdown, but by 2026 this is an expected feature in the class, not a differentiator. Useful, not remarkable.
≈ Now standardMarketing specs vs. the physics. The math is simple, battery capacity and a few formulas, so let us run it.
Peak watts make a great headline; they are not what carries you across town for more than a few seconds. Note that listings vary on the power figure.
Independent specs (autoevolution, the maker, allelectricmotorcycle) put the i300's motor at about 14 kW peak, an interior permanent magnet design. Convert to the unit everyone feels:
The headline gap is small in absolute terms but big in proportion, because the battery is tiny. The 37 mi figure is an eco best case; normal riding lands lower. Here is the arithmetic.
Step 1, real energy in the tank. Range starts with how much energy the battery holds: voltage × amp-hours. The i300 runs two removable 72V packs for a total around 2.5 kWh nominal.
Step 2, how much you spend per mile. Consumption (Wh/mi) is the whole game, and it rises with speed because drag rises with the square of speed. A small, performance-minded bike ridden hard sips less efficiently.
Small packs charge fast, and that is genuinely the i300's saving grace on range: a quick top-up offsets the short legs, if you have the time and a socket.
Shopping for one of these, you will see the same bike listed with different numbers. They are not all lying, here is how to read them.
| You will see | What it really is | Trust it? |
|---|---|---|
| 2.5 kWh / 1.44 kWh | Battery capacity. Most current sources cite ~1.25 kWh × 2 = 2.5 kWh; an earlier figure of ~720 Wh per pack also appears. Check the listing's date. | verify spec date |
| 14 kW | Peak motor power, the honest verified figure across independent specs. | real (peak) |
| 11 kW | A lower figure that appears in some listings; independent specs land at 14 kW peak. | cross-check |
| "37 mi range" | Eco mode, low speed, flat ground. Normal riding lands nearer 30 mi. | eco best-case |
| ~97 km/h top speed | Electronically restricted ceiling, about 60 mph. Genuinely reached. | honest |
The sticker is the smallest number in the story. Here is the whole bill.
The price is a headline, not a checkout total. Here is roughly what leaves your bank account on day one for a street-legal scooter.
| Line item | Typical | Notes |
|---|---|---|
| Bike (price) | ~$9,000 | UK pricing converted to USD; varies by market |
| Shipping / delivery | varies | Direct from a small-volume UK maker |
| Registration / road tax | varies | Moped/scooter class; depends on country |
| Starter gear (helmet, gloves) | $300–$400 | Required for a 60 mph machine |
| Realistic out-the-door | ≈ $9,400+ | Before delivery and local taxes |
The number almost no one shows you. We itemize it, show the math, and state every assumption so you can adjust it to your own riding.
| Cost over 5 years | Estimate | What drives it |
|---|---|---|
| Purchase (price) | $9,000 | UK price converted; tax/delivery vary |
| Insurance & registration | $1,500 | Moped/scooter class |
| Gear (one-time) | $400 | Helmet, gloves |
| Maintenance & consumables | $500 | Tires, brakes; low-mileage city use |
| Electricity (charging) | $100 | Almost nothing, math below |
| Battery (replace / upgrade) | $0 | None expected in 5 yr |
| 5-year total (before resale) | ≈ $11,500 | |
| Resale value (yr 5) | − $3,500 | ~40%; small-volume brand, uncertain |
| Net true cost to own | ≈ $7,000 | ≈ $1,400 / year |
What breaks, who fixes it, and whether you can get parts.
We read the reviews and coverage so you do not have to, and summarize the recurring themes. With a young, low-volume bike, long-term owner data is thin.
A bike is only as ownable as its parts supply, and here the i300 asks you to back a startup.
Zapp is a small UK startup with a limited direct sales and service footprint and minimal aftermarket. Parts and support availability outside core UK and EU markets is a concern, and there is no deep independent network of shops that know this bike. Budget for the possibility that service means going back to the maker.
| Part category | Availability | Notes |
|---|---|---|
| OEM batteries / electronics | via maker | Proprietary; limited footprint |
| Service & support | limited outside UK/EU | Small-volume direct model |
| Aftermarket upgrades | minimal | Young platform, no ecosystem yet |
| Consumables (tires, pads) | standard | Generic scooter sizes |
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 7 here means the same thing as a 7 anywhere.
Our standing methodology, run identically on every e-moto, including bikes we would otherwise have reason to flatter.
The only honest way to compare two batteries. Two ~1.25 kWh packs make ~2.5 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: gentle riding sips, hard riding costs more. Drag rises with speed².
Always ask which number a spec quotes. Peak sells bikes; continuous moves them.
"Fast charging" is meaningless without the charger's wattage. The ×1.1 covers losses and taper.
| Cost assumption | We used | Change it if… |
|---|---|---|
| Annual mileage | 2,000 mi/yr (10,000 / 5 yr) | You ride more → maintenance & tires rise |
| Electricity rate | $0.17 / kWh (US avg) | Your utility differs |
| Insurance & registration | Moped/scooter class, ~$300/yr | Your region differs |
| Battery life | No replacement in 5 yr | Very hard use → sooner |
| Resale | ~40% of price at yr 5 | Small-volume brand; uncertain |
We cite everything and date it, because specs, prices and tariffs 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 May 2026. Manufacturer pages state claimed specs; treat them as marketing figures, not independent tests. Battery capacity figures have shifted between listings (an earlier ~720 Wh per pack versus the current ~1.25 kWh per pack), and we flag that where it affects the range math.
