Freesky Eurostar Turbo M-410
Take the Ranger Air's drivetrain and put a top tube on it: that is the Eurostar Turbo M-410. Identical 2000W+2000W motors, 48V 25Ah pack, 34 mph and 60–105 miles — but a diamond EMTB frame and a 120 mm travel fork. At $1,349 you are paying $50 for geometry, not power.
- 4,000WPeak power

Every figure above is Freesky's own published specification for the Eurostar Turbo M-410, read from www.freeskycycle.com/products/eurostar-turbo-m-410 on 2026-08-24. Manufacturer claims, not Redtail test results — we label them that way rather than dress them up.

Who the Eurostar Turbo M-410 is for
Buy it if
- Riders who want a top tube — standover clearance and a frame you can throw around rather than sit in
- Anyone who prefers a conventional 120 mm travel fork to a downhill unit
- Buyers cross-shopping the Ranger Air who want the same power in a mountain-bike shape
- Riders 5'3" and up: this is the shortest fit floor of the 26-inch Freesky bikes
Skip it if
- You want the lightest bike here — at 99 lb this is the heaviest of the 4,000W group
- Swinging a leg over a 99 lb bike is a problem; the Ranger Air is the same drivetrain, step-through
- You need a road-legal machine. 34 mph is outside every US e-bike class
- You want long-travel suspension. The 120 mm fork here is less than the downhill units on the step-through bikes
The Eurostar Turbo M-410 in detail
Why the frame is the whole decision
This bike and the Ranger Air share a motor system, a battery, a brake set, a tire size, a drivetrain and a top speed. What differs is the frame: EMTB diamond geometry with a top tube against a step-through. If you are choosing between them, ignore the spec sheet and choose the shape you want to ride.
2000W + 2000W, 210 N·m combined
Two brushless peak motors, front and rear, at 105 N·m each. Freesky rates the pair at 34 mph under pedal assist. The dual-motor layout earns its keep on loose climbs, where a single rear wheel breaks traction and two driven wheels simply keep pulling.
A 120 mm fork, and what that trades
Freesky fits a 120 mm travel suspension fork here rather than the downhill double-shoulder units elsewhere in the range. That is less travel — and also less weight over the front wheel and more conventional steering feel. On trail rather than drops, it is the more sensible choice.
48V 25Ah, 6–8 hours to full
The same FP4825R0 pack as the Ranger Air, Rocky Pro and Wild Cat, rated 60–105 miles and charged in 6–8 hours from the US 3A smart charger. It is also the pack with the cleanest paperwork in the range — certificate U10 128702 0003 covers it exactly.
99 lb, the honest number
This is the heaviest bike in the 4,000W group, four pounds up on the Ranger Air and sixteen on the Swift Horse. On the trail you will not notice. Loading it onto a rack, you will.
The honest ledger
Green flags
- Brakes are the real thing: 180MM 4-piston Hydraulic Brakes. Four-piston hydraulics on a bike this heavy is not a given at this price.
- Suspension: Front and Rear Suspension, with a Suspension Fork 120 MM Travel.
- The complete-system UL 2849 certificate exists, names this model on its face, and we link the PDF — not a badge image.
- Rated to carry 400 lbs.
- Charging time: 6–8 hours.
Red flags
- At 34 mph assisted, this is outside every US e-bike class. Off-road and private land, not bike paths.
- Freesky publishes peak wattage only — no rated figure. Under our own rating system an undisclosed specification scores zero, and we do not guess at it.
- It weighs 99 lbs. Getting it onto a hitch rack is a two-person job.
- Cadence (speed) sensor rather than a torque sensor — assist comes on with pedal rotation, not with how hard you push.
What Freesky publishes about certification
A badge image on a product page is not a certificate. Below is what the certificate document itself says — issuer, number, standard edition, the models printed on its face — and what it does not cover. Every PDF is hosted by us, so the link will still work if Freesky reorganises their files.
UL 2849 (complete e-bike electrical system)
CoveredTÜV SÜD America certificate U14 128702 0008 Rev. 00, issued 2025-07-31, names M-530, M-540, M-410, A-340 at a rated voltage of 47,19VDC. Tested to UL 2849:2020/R:2022-12 and CAN/UL 2849:2022. Read the certificate (PDF).
UL 2271 (battery pack)
CoveredTÜV SÜD America certificate U10 128702 0003 Rev. 00, issued 2025-04-03, covers battery FP4825R0 at 47.19Vd.c., 24.5Ah — the pack this bike ships with. Read the certificate (PDF).
All 3 UL 2271 battery certificates in this range — certificate no. U10 128702 0001 Rev. 00, U10 128702 0003 Rev. 00, U10 128702 0009 Rev. 00 — carry the same remark on their face: “The battery is used for off-road LEVs.” That is the certifying body describing the intended use, not our characterisation of it.
Speed and the law
Outside the federal and state e-bike definitions — off-road and private land
Freesky rates this bike at 34 mph under pedal assist. The federal low-speed electric bicycle definition (15 U.S.C. § 2085) and every state three-class framework stop at 28 mph, so this machine sits outside them on speed alone — before wattage is even reached. It is not a Class 1, 2 or 3 e-bike, and we will not sell it as one.
Freesky does not publish a rated (nominal) motor wattage for any bike in this range; the figures they publish are peak. The statutory tests are written against the rated figure, so the wattage limb of those tests cannot be run on published data. We say that rather than substitute the peak number, which would be the wrong number.
Freesky's own manual puts it this way: “laws regulating the use of battery-operated bicycles on public roads, parks, and other open areas may vary by state and locality. It is important to consult with your local authorities before riding your e-bike in public areas.” Buy it for private land, OHV areas, and anywhere motor-vehicle rules allow. Check your own state and city before you ride it anywhere public — and ask us, we will put the answer in writing.
We publish a state-by-state e-bike law hub, and if you want your own state answered in writing before you order, ask us and we will put it in an email you can keep.
How to read this spec sheet
Peak, not rated
Freesky publishes peak motor wattage on every model and a rated (nominal) figure on none of them — not on the product pages, not in the comparison table, not in any of the seven user manuals. Peak is the short-burst ceiling; rated is the continuous figure that statutes are written against. A Freesky peak number and another brand's rated number are two different quantities, and comparing them directly will mislead you.
Range is a range for a reason
Every range figure here is Freesky's, quoted as a span. Plan around the bottom of it. Rider weight, terrain, temperature, tyre pressure and throttle use all take from the top.
Top speed is unloaded
Manufacturer top speeds are measured under favourable conditions. They are useful for comparing models within a range and much less useful as a promise about your commute.
Size and fit
Freesky quotes a rider-height range of 5'3"–6'5" for the Eurostar Turbo M-410, on a 30.9*300MM Alloy Seatpost. That is the manufacturer's fit window, not a guarantee — if you are near either end of it, tell us your inseam and we will tell you honestly whether it will work.

What we counted
Measured by Redtail
We pulled Freesky's entire published catalogue on 2026-08-24 — all 60 products and every variant — and counted what could actually be bought that day. Freesky could sell 30 of its own 38 published bike configurations on the pull date — 79%. 0 of its 10 bike models had no buyable colourway at all.
Across the accessory and parts range, 108 of 136 variants were buyable. We mirror that availability daily rather than list a colour nobody can ship — which is why some options on this page may be greyed out today and back tomorrow.
Between 2026-08-23 and 2026-08-24 three Camouflage colourways rose $50, one accessory went out of stock, and one product was withdrawn from the catalogue entirely. That is why this page is re-checked daily rather than copied once.
Warranty
Buy the bike from Redtail and Redtail handles the claim. Send photos or video of the issue with your order number and we take it from there — we file and manage the claim with Freesky on your behalf, and we do not send you to the manufacturer to argue it yourself.
Who covers you
Freesky's published warranty says, in its own words: “This warranty applies only to products purchased directly from the official FREESKY website (www.freeskycycle.com).” and directs buyers from authorised dealers to “their respective warranty policies”. Redtail is a dealer — so the cover on your bike is Redtail's, and the claim comes to us.
What Freesky stands behind
- Motor, battery and controller: 24 months (orders on or after 13 November 2025); 18 months before that date
- All other components: 12 months
- The applicable warranty period begins on the original purchase date.
What is excluded
- Consumables and wear parts — tyres, tubes, brake pads, cables and housing, grips, chain, spokes
- Incorrect assembly, water damage, accidents, or improper or negligent use
- Operation or maintenance contrary to the product's maintenance instructions
- Defects inherent to the normal service life of the product
Freesky's warranty terms as published at www.freeskycycle.com/pages/warranty-policy, read 2026-08-24. Reproduced as context for what the manufacturer stands behind; your cover is Redtail's.

Frequently asked questions
What is the difference between the Eurostar Turbo M-410 and the Ranger Air M-540?
Frame and fork. Both run 2000W+2000W peak motors, a 48V 25Ah pack, 180 mm four-piston brakes, 26 × 4.0 tires, Shimano 7-speed, 34 mph and 60–105 miles. The M-410 is an EMTB frame with a 120 mm fork at 99 lb; the M-540 is a step-through with downhill full suspension at 95 lb.
Is the Eurostar Turbo M-410 street legal?
No. At 34 mph assisted it sits outside the federal low-speed electric bicycle definition and every state three-class framework, which stop at 28 mph. Off-road and private land only.
Is the Eurostar Turbo M-410 UL certified?
Yes, at both levels. Certificate U14 128702 0008 from TÜV SÜD America names the M-410 under UL 2849 for the complete electrical system, and U10 128702 0003 covers the FP4825R0 24.5Ah pack under UL 2271. Both PDFs are linked on this page.
What size rider does the Eurostar Turbo M-410 fit?
Freesky quotes 5'3"–6'5", the lowest fit floor of the 26-inch bikes in this range. Riders over 6'5" should look at the Ranger Air or Alaska Pro, both quoted to 6'8".
How long does the Eurostar Turbo M-410 take to charge?
6–8 hours on the supplied US Standard 3A smart charger, for the 48V 25Ah pack.
Does the Eurostar Turbo M-410 have a torque sensor?
No. Freesky specifies a speed sensor, so assist responds to pedal rotation rather than to how hard you push. The Rocky Pro A-320 is the only bike in this range with a torque sensor.
The bottom line
A $50 premium over the Ranger Air buys you a top tube and a more conventional fork, and costs you four pounds. That is the entire decision. If you want a mountain-bike shape, this is the one; if you want to step through, save the fifty dollars. Either way it is an off-road bike, and we will not sell it to you as anything else.
