Leaperkim Lynx S Review: 3,800 W, 2,700 Wh, Claimed Range and Real Price

The Leaperkim Lynx S is the upgraded version of the Lynx: a 20-inch electric unicycle (EUC) with a 3,800 W motor, a 2,700 Wh battery and 90 mm of hydraulic suspension. It costs more than the original Lynx in every store we checked, and it is easy to confuse with the older wheel. The harder problem is evidence: we found no independent test of its range or top speed, so every performance number below is a claim.

We did not ride this wheel. The specs come from eRideHero's spec page, ewheels, e-rides (EU), NextGen Mobility and eScooter Clinic. The only ride impressions we found are from Freshly Charged's review of the original Lynx, which shares the same 151 V platform but is not the same wheel.

Which Lynx is it?

• Lynx (original): 3,200 W nominal and 8,000 W peak, 2,700 Wh, about 88 lb. ewheels lists it at $3,299 (list price $3,999).
• Lynx S: 3,800 W nominal and 10,000 W peak, the same 2,700 Wh pack and 90 mm suspension, and about 94 lb. ewheels lists a higher top speed, a brighter headlight and about 5 lb more weight than the original, and e-rides adds a retractable kickstand, adjustable pedal height and Hall-sensorless firmware to the list of changes.

eRideHero lists it as the "Veteran Lynx-S", while ewheels sells it as the "Leaperkim Lynx-S", so search for both names. Our own arithmetic: the nominal power gain over the original is about 19% (3,800 against 3,200 W) and the peak gain is 25% (10,000 against 8,000 W). That explains why one seller says 18% more power and another says 25%.

At a glance

What the numbers really tell you

Range claims run from 50 miles to 100 miles for the same wheel, and no tester has measured it. At 60 miles the claim needs about 45 Wh per mile; at 100 miles it needs only 27. The KingSong S22 Pro, which eRideHero did test, used about 53 Wh per mile (42.1 miles from 2,220 Wh). At that rate a 2,700 Wh pack would give roughly 50 miles. This is our estimate, not a measurement, and a faster, heavier wheel ridden hard can do worse.

Speed is also a claim. NextGen Mobility says the 65 to 70 mph figure is an estimate built from testers in China who reached 56 mph without extra field-weakening software, and calls the 93 mph lift-off speed a software limit. Treat 56 mph as the only number tied to a test, and it is a second-hand report; treat the rest as limits, not cruising speeds.

What a reviewer said about the original Lynx

Freshly Charged tested the original Lynx. The reviewer, who weighs 220 lb, found no pedal dipping or beeping on deep, rutted hills, and said the suspension felt comfortable on 6-foot drops. The reviewer also noted that Leaperkim switched from Samsung 50E to 50S cells for a higher discharge rate and a better safety margin, at the cost of a shorter cycle life. These points probably carry over to the Lynx S, but we cannot confirm that.

Complaints about the original: no kill switch, very loud beeps, no pads from the factory and rear turn signals that only work while turning. Seller pages for the Lynx S say nothing about reliability, so there is no evidence either way.

Price check

At the US price the Lynx S costs about $1.37 per watt-hour, against about $1.22 for the original Lynx; the EU price works out to about €1.04. The extra $400 over the original buys the stronger motor and about 5 lb more weight. By comparison the KingSong S22 Pro we reviewed lists at $2,449 with a tested 42.1 miles from a 2,220 Wh battery.

Parts at ewheels: Lynx S 3,800 W motor assembly $545 (on backorder), a single shock assembly $205, a headlight $79.

Who it suits

Buy it if you want a very powerful 20-inch suspension wheel, you ride at speed on rough roads and you accept that nobody has independently measured its range. Skip it if you carry your wheel up stairs, need a documented range figure or want a wheel that dealers describe with the same specs on every page.

Check your national rules before riding on a public road, because rules for unicycles differ a lot between countries.
