How we score electric unicycles

We review electric unicycles from the brands' and sellers' published product, specification, warranty and returns pages and their US prices, read on the date shown on each page (last on November 13, 2026). We don't run a test track: we read, compare and score what each page states. Every wheel gets one score out of 10, and that score is the same on every page of the site.

What are the 8 criteria?

How is each criterion scored?

Each criterion is turned into a score out of 10. Where a scale is given as anchor points, we interpolate in a straight line between them and cap at both ends.

• Price: the dated US price at the seller we link, compared with the median of our list ($1,999). Ratio to the median: 0.25× → 10, 0.5× → 9, 0.75× → 8, 1× → 7, 1.5× → 5.5, 2× → 4, 2.5× → 3.
• Battery: capacity in watt-hours, as published: 400 Wh → 3, 750 Wh → 5, 1,500 Wh → 7, 2,400 Wh → 8.5, 3,000 Wh → 9, 4,200 Wh → 10. We score capacity and not claimed miles, because every seller measures range its own way.
• Suspension: travel in millimeters, as published: 0 mm → 3, 60 mm → 6.5, 75 mm → 7.5, 85 mm → 8.5, 90 mm → 9, 100 mm → 10. A wheel sold without suspension takes the bottom of the scale.
• Published protections: a water rating on the page (4 points for IPX6, IP56 or better, 3 for IPX5 or IP55, 2.5 for IP54), a UL certification stated on the page (3 points) and a smart BMS stated on the page (3 points).
• Motor power: nominal watts, as published: 800 W → 3, 1,000 W → 4, 2,200 W → 6, 2,500 W → 6.5, 3,000 W → 7.5, 4,000 W → 8.5, 5,000 W → 9.3, 6,000 W → 10. Peak watts are shown in each review but not scored.
• Weight: pounds to lift and carry, lighter is better: 32 lb → 10, 41 lb → 9, 51 lb → 8, 66 lb → 6.5, 77 lb → 5.5, 90 lb → 4.5, 103 lb → 3.5, 112 lb → 3.
• Rider load: the maximum load the page states, gear included: 220 lb → 4, 265 lb → 6.5, 300 lb → 8.5, 309 lb → 9, 330 lb → 10.
• Warranty, returns and shipping: warranty in years (1 → 6, 2 → 9) for 50%, return window in days (0 → 1, 14 → 5, 30 → 8) for 25%, shipping for 25% (10 when the seller ships free, 4 when shipping is charged at checkout).

Why isn't top speed a criterion?

Because a claimed top speed is not a speed anyone should plan to ride. Some listings quote a figure close to the motor's no-load or "free-spin" speed, and a wheel near its limit has no power left to keep the rider balanced. We print every speed and range figure as the brand's or the seller's claim, and we score the things that give margin at normal speeds: motor power, battery, suspension and published protections. Our ranking of the fastest electric unicycles lists the claims and is ordered by motor power for the same reason.

What happens when a figure isn't published?

A criterion the seller's page doesn't publish scores 2/10. We can't credit what isn't stated, and a wheel should not win on silence. A wheel with no published price, or fewer than 5 published criteria, gets no score at all.

How does the raw score become the score you see?

The raw score is the weighted average of the 8 criteria. Every wheel we list is a current product sold and shipped in the United States, so we show it on an editorial scale: displayed score = 7.5 + 0.72 × (raw score − 5.1), kept between 7.5 and 9.6. The order of the raw scores never changes. Labels: Excellent from 9.0, Very good from 8.5, Good from 8.0, Fair below 8.0.

Why do two wheels never show the same score?

Scores are shown with one decimal, so two wheels can round to the same number. When that happens, the order comes from the formula first and then from a published tie-break:

1. the higher raw score (before rounding);
2. then the lower price per watt-hour of battery;
3. then the lighter wheel;
4. then alphabetical order.

The wheel placed second then shows 0.1 less than the one above it, and so on down the list, so every displayed score is different and the order is still the formula's. Scores stay between 7.5 and 9.6. Right now this applies to the InMotion V9 (formula 9.1, shown 9.0), the InMotion V14 Pro (formula 9.1, shown 8.9), the Leaperkim Lynx-S (formula 8.3, shown 8.2), the Leaperkim Sherman-L (formula 8.3, shown 8.1), the KingSong S22 Pro (formula 8.3, shown 8.0), the KingSong 16X Pro (formula 8.1, shown 7.9), the InMotion V8S (formula 8.1, shown 7.8).

How are the rankings by need built?

Each ranking puts the same criteria in a different order of importance, and most only admit wheels that meet a condition: 66 lb or less and a claimed top speed of 37 mph at most for beginners; under 80 lb with a built-in trolley handle for commuting; at least 75 mm of suspension travel for off-road; 1,500 Wh or more for long range; a claimed 42 mph or more for the fastest list; a price at or under $1,500; a published load limit of 300 lb or more for heavy riders. The weights change the order of the list, never the score: each wheel keeps its one overall score everywhere.

Where does the data come from?

• Specs and prices come from the US product page of the seller we link (the brand's own store, or eWheels for the brands that don't sell direct in the United States) and its warranty, returns and shipping pages. Every review links its sources.
• Prices are the price you could pay on the date shown, in US dollars. When a seller shows a discount, we use the discounted price and say so, with the regular price next to it.
• Stock is read on the same pages. A wheel sold out at the linked seller is flagged with the date, and the ranking keeps the formula's order.
• We don't use user ratings or star averages from stores. Where a review quotes a buyer, the quote is attributed and dated.
