A sub-140 lb, 72V Sur-Ron-class e-dirt bike that nails fun-per-dollar for about $5,000, decoded with real physics: where the range actually goes, rated versus peak power, what it truly costs over five years, and the durability asterisk a hard-use test exposed. Sources on everything.
A light, quick, low-maintenance off-road e-moto with genuine value, wrapped around a range number built on a crawl. Plan for ~15 to 50 real miles depending on how hard you ride (not 90), a 5 kW rated motor with a 12 kW burst, about $4,350 net to own over 5 years, and no, it is not street-legal as shipped.
Assumptions: recreational off-road use, ~1,500 mi/yr, $0.17/kWh, maintenance ~$100/yr, light insurance/registration, resale ~40% of sticker at year five (budget Chinese e-moto). Full table in §10.
Every module behind the headlines: who it is for, claims vs. physics, true cost, the durability story, parts, and the standard scorecard. All sourced.
A sub-140 lb, 72V Sur-Ron-class e-dirt bike with a 2.88 kWh Samsung-cell pack, a 5 kW rated motor with a 12 kW peak, and a genuine ~60 mph, for about $5,000. Plan for ~15 miles hard, up to ~50 at a crawl (not 90), ~$4,350 net to own over 5 years, and no, it isn't street-legal as shipped. One hard-use pro test broke it; everyday reviewers love the value. Here is exactly how we get there.
Start here, the right answer depends entirely on who is asking.
Same bike, very different answer depending on the rider. We lead every report with this so nobody buys the wrong machine.
The sweet spot. Light, punchy and quick (~2.36 s to 30 mph), with branded Samsung cells and very low maintenance. A genuine afternoon of off-road fun for budget money.
Where the SS 2.0 shines. A 72V platform and a real 60 mph undercut a lot of pricier rivals, and the 2.0 revision strengthened the footpeg and linkage hardware that fails first on cheap e-motos.
The asterisk. GritShift's hard-use pro test, bluntly titled "It Broke Too Quickly," found competition-level abuse exposes the bike's limits. The 2.0 helped, but this is a recreational ceiling.
Not street-legal in stock form in most of the US: no DOT lights, signals, or on-road VIN. Faster than a bicycle, but a poor and legally risky commuter.
Same bike, two stories. 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 reasons to pick this over a pricier rival, rated honestly. Each badge tells you whether it is a real edge, normal for the class, or marketing gloss.
A 72V architecture and a real 60 mph for budget money. Higher voltage and genuine top-end undercut much of the class on price, which is the core of the value pitch.
✓ SolidThe 72V / 40Ah pack uses branded Samsung cells, a real step up from the generic cells common in budget e-motos. The pack is also removable for indoor charging.
✓ SolidAdjustable power, throttle and regen from a phone, carried across the E Ride line. Genuinely handy for tailoring or capping a new rider, but most serious e-motos now do this.
≈ Now standardE Ride strengthened the footpeg mounting and linkage hardware, exactly the parts that fail first on cheap e-motos. A targeted, honest durability fix, not a marketing relaunch.
★ Genuine edgeMarketing 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 down the trail for more than a few seconds. Read the rated number underneath it.
Dealers list the SS 2.0 as a 12 kW machine. That is the brief peak. The motor's rated (continuous) figure is about 5 kW, sometimes quoted as 6 kW. Convert both to the unit everyone feels:
The headline gap. The claim is not a lie, it is a best-case crawl you will basically never reproduce on a dirt bike. Here is the arithmetic.
Step 1, real energy in the tank. Range starts with how much energy the battery holds: voltage × amp-hours.
Step 2, how much you spend per mile. Consumption (Wh/mi) is the whole game, and it explodes with speed because drag rises with the square of speed. A gentle 25 mph crawl sips ~50 Wh/mi; flogging a light bike off-road can hit 170+.
~60 mph claimed and class-competitive. The figure itself is plausible. But hitting top speed is exactly what destroys the range above.
Held flat-out, a light bike draws hard just to push air, so consumption climbs toward ~150 to 180 Wh/mi. Run the same range formula pinned:
So the "60 mph" and the "90 miles" on the same spec sheet are mutually exclusive: you get one or the other, never both. That is the most important thing the marketing never says out loud.
Charge time is just battery size ÷ charger power, so a vague "about 2 hours" claim depends entirely on which charger is in the box.
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? |
|---|---|---|
| 72V 40Ah | The battery. Multiply V×Ah: 2.88 kWh nominal. The number that sets real range. | do the math |
| 5 kW / 6 kW | Rated (continuous) motor power, the honest "what it sustains" figure. | real |
| 12 kW peak | Brief burst before thermal rollback. The launch number, not the cruise number. | burst only |
| "50 to 90+ mi" | Low-speed crawl on flat ground; the top end assumes ~15 mph. | lab best-case |
| "Street legal" | Off-road / closed-course only in most US states as shipped. | verify locally |
| SS vs S, 2.0 vs older | Trim and revision. The 2.0 added the footpeg/linkage fixes; check the year and trim. | check trim |
The sticker is the smallest number in the story. Here is the whole bill.
The MSRP is a headline, not a checkout total. Here is what actually leaves your bank account on day one.
| Line item | Typical | Notes |
|---|---|---|
| Bike (MSRP) | $5,099 | Via US dealers such as Voro Motors |
| Shipping / freight | $150–$300 | Crate freight; sometimes baked in |
| Sales tax (~8%) | ~$410 | Some states exempt off-road vehicles |
| Setup / assembly | $0–$150 | Free if you uncrate it yourself |
| Starter gear (helmet, gloves, armor) | $300–$500 | Non-negotiable at 60 mph |
| Realistic out-the-door | ≈ $5,900–$6,500 | Before a single mile |
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 (MSRP) | $5,099 | Excl. gear; tax/freight vary by state |
| Gear (one-time) | $500 | Helmet, gloves, armor |
| Electricity (charging) | $55 | Almost nothing, math below |
| Tires, brakes, consumables | $500 | ~$100/yr recreational use |
| Insurance / registration | $200 | Light, off-road only where applicable |
| Battery (replace / upgrade) | $0 | None expected in 5 yr |
| 5-year total (before resale) | ≈ $6,354 | |
| Resale value (yr 5) | − $2,000 | ~40% of sticker, budget Chinese e-moto |
| Net true cost to own | ≈ $4,354 | ≈ $871 / year |
What breaks, who fixes it, and whether you can get parts.
We read the forums, reviews, and owner groups so you do not have to, and summarize the recurring themes, not cherry-picked raves.
A bike is only as ownable as its parts supply. Here the SS 2.0 is fair: a healthy specialist scene, but no broad OEM dealer bench.
The SS 2.0 is well-supported by specialist vendors such as Electric Cycle Rider, GritShift and Voro Motors, with a growing catalog of batteries, chargers, tires and upgrades. There is no broad OEM dealer network, so you will lean on these enthusiast shops for parts and service rather than a local franchise.
| Part category | Availability | Rough cost |
|---|---|---|
| Batteries / chargers (72V) | fair to good | $120–$1,800 |
| Tires, brakes, consumables | good | $20–$250 |
| Ergonomic / chassis upgrades | good | $40–$300 |
| OEM electronics / controllers | fair | via specialist vendors |
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. 72V × 40Ah holds 2,880 Wh.
You never use 0 to 100%. The BMS holds a reserve and voltage tapers at the bottom. We assume ~88%.
Consumption is the lever: ~50 Wh/mi gentle, ~90 mixed, 170+ flat-out on a light bike. 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 | 1,500 mi/yr (7,500 / 5 yr) | You ride more → maintenance & tires rise |
| Electricity rate | $0.17 / kWh (US avg) | Your utility differs |
| Sales tax | ~8% | Your state differs / exempts off-road |
| Battery life | No replacement in 5 yr | Very hard use → sooner |
| Resale | ~40% of MSRP at yr 5 | Condition & market vary |
