A polished 125cc-equivalent e-scooter Yamaha ran as a 100-unit lease and demonstration program, not a product. Where the range really lands, why the fast charging is genuinely clever, and why this is a signpost, not a purchase. Sources on everything.
A well-finished urban scooter that Yamaha deliberately refused to sell, running instead as a limited lease (about 20,000 yen a month in Japan). Plan for ~45 real miles (not 65), genuinely useful fast charging (0 to 90% in about an hour), and remember the catch: you could never own one. Treat it as a demonstrator, not a buyable bike.
Why no 5-year table: ownership cost needs a purchase price, resale, insurance and parts pipeline. None of those existed for the E01, which only ran as a lease. We never fabricate a number to fill a section, so this one stays a lease figure. More in §7.

The E01 is not a product, it is a science experiment with a Yamaha badge. A large-format urban scooter pitched at the 125cc class, with an 8.1 kW motor and a fixed 4.9 kWh battery, run as a 100-unit lease to gather data. Plan around ~45 real miles (not 65), enjoy the genuinely good fast charging, and accept that you can't have one. Admire the engineering, note the fast charge, and treat it as a signpost. Here is exactly how we get there.
Start here, though the honest first answer is that you cannot buy it. Read on for who it would have suited.
Because the E01 was lease and demonstration only, the real audience is anyone studying where Yamaha's electric scooters are headed. We still frame who the bike itself would fit.
A polished 125cc-equivalent city tool: 8.1 kW, traction control, three ride modes, and a fast-charge option that suits lunch-break top-ups. The catch is the fixed 4.9 kWh pack and ~45 real miles, fine for a city loop, tight for much more.
The real value of the E01 is as a preview. It tells you what a serious Yamaha e-scooter looks and rides like, refined and well finished, which is exactly why it matters as a catalog entry.
You can't. It ran as about 100 units on a three-month lease (roughly 20,000 yen a month in Japan), then the program ended. There is no purchase price, no dealer stock, and no second-hand market.
Same scooter, two stories. The struck-through line is the headline; the big number is the honest one. The "why" is in Part C.
What is genuinely clever here, and which features are really table-stakes. The part the press release never ranks for you.
The E01 is a clean, capable preview, and its standout is the charging story. Each badge tells you whether it is a real plus or normal for 2022 and after.
A quick charger does 0 to 90% in about an hour, a normal home charger does 0 to 100% in about five hours, and the bundled portable charger trickles a full charge in about 14 hours. The fast option is the win: a lunch-break top-up, which is what urban riders actually want.
✓ SolidPower, Standard and Eco modes (Eco caps power at 5.4 kW), with traction control managing the instant electric torque. A feature set still uncommon in the scooter class, and a sign of how seriously Yamaha treated the demonstrator.
✓ SolidPress impressions praised the build quality and refinement, which is what you get when a big maker treats a 100-unit test fleet like a flagship. It feels like a product even though it never was one.
★ Genuine edgeNon-swappable. That keeps the bike tidy and lets Yamaha integrate the pack cleanly, but it means no carrying it indoors, no spare, and no swap. For a fixed-pack city scooter the fast charger is the answer Yamaha chose, and it mostly works.
≈ Class-typicalMarketing specs vs. the physics. The math is simple, battery capacity and a few formulas, so let us run it.
Yamaha is fairly honest here: the E01 quotes 8.1 kW maximum, with Eco mode capping power at 5.4 kW. Convert to the unit everyone feels.
The range claim is a best-case figure. Yamaha publishes the battery's voltage and amp-hours, so we can show the arithmetic exactly.
Step 1, real energy in the tank. Yamaha lists the fixed pack as 87.6 V and 56.3 Ah. Range starts there: voltage times amp-hours.
Step 2, how much you spend per mile. A heavier city scooter sips less when ridden gently and a lot more in faster mixed riding, because drag rises with the square of speed. Run the range formula at both ends.
Charge time is just battery size ÷ charger power, so a vague "fast" claim means nothing without the wattage. The E01 actually backs it up with real numbers across three chargers.
Because the E01 was a demonstrator, third-party listings repeat mixed numbers. Here is how to read them against Yamaha's own figures.
| You will see | What it really is | Trust it? |
|---|---|---|
| 8.1 kW / 5.4 kW | Power-mode max vs Eco-mode cap. About 10.9 hp and 7.2 hp respectively. | real |
| "62 mph" | Some listings show this; independent coverage (RideApart) verifies a real top speed near 45 mph (72 km/h). Plan for the lower, verified figure. | listing high |
| "104 km range" | Best-case, gentle low-speed riding. Mixed real use is closer to 72 km. | best case |
| 87.6V / 56.3Ah | The fixed battery. Multiply: ~4.9 kWh. Non-swappable. | real |
| "Buy the E01" | You can't. Lease and proof-of-concept only, about 100 units, then the program ended. | never sold |
For most bikes this is a 5-year table. For the E01 it is a single lease figure, because that is all that ever existed.
A full 5-year cost-to-own breakdown for this model cannot be itemized, because the E01 was never sold at a retail purchase price. We never fabricate a number to fill a section, so here is what is real.
| Line item | Figure | Notes |
|---|---|---|
| Lease (Japan program) | ~20,000 yen / mo | About $169/mo, three-month fixed term, tax incl. |
| Purchase price | not offered | Never sold at retail |
| Insurance / registration | within program | Handled inside the lease, not an owner cost |
| Resale value | no market | No second-hand market existed |
| Electricity (charging) | low | ~4.9 kWh per full charge; cheap to "fuel" |
| 5-year cost to own | not applicable | No purchase, no resale, no parts pipeline |
Or rather, why you mostly can't, and what the limited program tells us anyway.
Because the E01 only ran as a limited lease and demonstration, there is no meaningful body of long-term owner reliability data. We summarize what coverage exists and flag the gap plainly.
A bike is only as ownable as its parts supply. For the E01 there essentially is none.
Because the E01 was never a retail product, there is no consumer parts pipeline, no dealer stock for buyers, and no aftermarket. It was supported only within Yamaha's program markets, for the duration of the program. If you somehow obtained one outside that program, you would be on your own for parts and service.
| Part category | Availability | Notes |
|---|---|---|
| OEM parts (consumer) | none | No retail pipeline |
| Dealer support | program only | Yamaha program markets, while active |
| Aftermarket | none | Never a retail platform |
| Battery (fixed pack) | program only | Non-swappable, no consumer supply |
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. A lease-only demonstrator scores low where ownership matters, by design.
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. 87.6V × 56.3Ah gives the E01's ~4.9 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 city riding sips less, faster mixed use spends more. Drag rises with speed².
Always ask which number a spec quotes. The E01 lists 8.1 kW peak and a 5.4 kW Eco cap.
"Fast charging" is meaningless without the charger's wattage. The E01 publishes real figures: ~1 hr to 90%, ~5 hr normal, ~14 hr portable.
| Cost assumption | We used | Note |
|---|---|---|
| Purchase price | None (lease only) | No retail sale ever happened |
| Lease | ~20,000 yen/mo (Japan) | Three-month fixed term |
| Electricity rate | Low; ~4.9 kWh/charge | Cheap to "fuel" in any market |
| Resale | No market | Lease-only, no second-hand sales |
| Parts | Program only | No consumer pipeline |
We cite everything and date it, because specs and programs 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. The E01 was a limited lease and demonstration program, not a retail product, which is why no purchase price or 5-year cost is published here.
