Quick answer

Every other bike here is built to impress you. The Rocky Pro A-320 is built to ride — the only Freesky with a torque sensor and an 8-speed drivetrain, the lightest at 77 lb, the slowest at 33 mph. On 20-inch wheels and a 5'1"–5'11" fit, it is also the only one made for shorter riders.

Who the Rocky Pro A-320 is for

Buy it if

  • Riders who want assist that answers effort rather than pedal rotation — this is the only torque-sensed bike Freesky makes
  • Shorter riders. The 5'1" fit floor is five inches below anything else in the range
  • Anyone who has to move the bike by hand: 77 lb is the lightest here, on the smallest wheels
  • Riders who want gears that work — an 8-speed against the 7-speed on every other model

Skip it if

  • You want top speed or peak power. At 2,500W and 33 mph this is the least powerful bike in the range
  • You want the longest range — 45–90 miles is the shortest here
  • You are over 5'11". Freesky's own fit range stops there, and 20-inch wheels will feel small
  • You need road-legal. Even the slowest Freesky is five miles per hour past the Class 3 ceiling

The Rocky Pro A-320 in detail

Freesky Rocky Pro A-320 — The only torque sensor in the range
Feel

The only torque sensor in the range

Every other Freesky uses a speed sensor: you turn the pedals, assist arrives. This one measures how hard you are pushing and answers proportionally. It is the single biggest difference in how an e-bike feels to ride, it is why this bike is worth $200 more than the Wild Cat, and it is the reason we would put a nervous first-time rider on this one.

Freesky Rocky Pro A-320 — Shimano 8-speed, not 7
Gearing

Shimano 8-speed, not 7

One more sprocket than anything else in the range. On a torque-sensed bike that matters more than it sounds: with assist responding to effort, having a gear that lets you put effort in cleanly is the difference between the system helping you and the system carrying you.

Freesky Rocky Pro A-320 — 20-inch wheels and a 5'1
Size

20-inch wheels and a 5'1" fit floor

20.0" × 4.0" fat tires on a step-through frame quoted from 5'1" to 5'11". Freesky's other bikes start at 5'3" or 5'4" on 26-inch wheels. If you have been told you are too short for a fat-tire e-bike, this is the one that was built for you.

Freesky Rocky Pro A-320 — 77 lb — the lightest thing here
Weight

77 lb — the lightest thing here

Small wheels, one motor and a 25Ah pack add up to the lightest bike Freesky sells: 77 lb, eighteen under the Ranger Air and forty-five under the Cheetah. Still heavy by bicycle standards, and still the easiest of these to get up a step or onto a rack.

Freesky Rocky Pro A-320 — Full-size brakes on a smaller bike
Stopping

Full-size brakes on a smaller bike

180 mm four-piston hydraulic brakes and downhill full suspension — the same stopping and damping hardware Freesky fits to bikes twenty pounds heavier and seven miles per hour faster. On the lightest bike in the range, that is a comfortable margin rather than a marginal one.

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 Dual Suspension, with a Downhill Full Suspension.
  • 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: 4–6 hours.

Red flags

  • At 33 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.
  • Only 2 of 4 colours are in stock right now (Red, Blue). We list what Freesky can actually ship.

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)

Covered

TÜV SÜD America certificate U14 128702 0007 Rev. 00, issued 2025-07-24, names A-320 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)

Covered

TÜV 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 33 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 5'1"–5'11" for the Rocky Pro A-320, 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

Does the Freesky Rocky Pro A-320 have a torque sensor?

Yes, and it is the only bike in the Freesky range that does. Every other model — Ranger Air, Ranger Plus, Eurostar Turbo, Wild Cat, Swift Horse, Alaska Pro, Cheetah and both Warriors — uses a speed sensor. Assist here responds to how hard you pedal, not merely that you are pedalling.

Is the Rocky Pro A-320 street legal?

No. At 33 mph assisted it is the slowest bike Freesky makes and still five miles per hour past the 28 mph Class 3 ceiling, so it falls outside the federal low-speed electric bicycle definition. Off-road and private land only.

What size rider does the Rocky Pro A-320 fit?

Freesky quotes 5'1"–5'11", the only model in the range built for riders under 5'3". It runs 20-inch wheels rather than the 26-inch fitted elsewhere.

Is the Rocky Pro A-320 UL certified?

Yes. TÜV SÜD America certificate U14 128702 0007 names the A-320 specifically under UL 2849 for the complete electrical system, and U10 128702 0003 covers its FP4825R0 24.5Ah battery under UL 2271. Both PDFs are linked on this page.

How far does the Rocky Pro A-320 go?

Freesky rates 45–90 miles, the shortest in the range, from a 48V 25Ah pack charged in 4–6 hours. That is the manufacturer's figure. Plan around the low end.

Which Rocky Pro A-320 colours are in stock?

As of 23 August 2026, Red and Blue can ship; Black and Green are out of stock at Freesky. We availability-match daily.

The bottom line

The thinking rider's Freesky, and the only one we would hand to someone who has never ridden an e-bike. A torque sensor, an extra gear, the lightest frame and a fit range that finally includes shorter riders — bought at the cost of being the slowest and shortest-range bike here. If you want to enjoy riding it rather than be impressed by it, this is the one.

How we verified this page.
  • Specifications read from Freesky's own product page on 2026-08-24 with the US market forced. An unforced request from outside the US renders another currency, so every price here was read with ?country=US and proven against the base feed.
  • Certificates were downloaded, read, and mapped to this bike by the model code printed on the certificate face — never by the filename.
  • Price and availability are re-checked against Freesky every day by script; this page follows what they actually charge and actually have.
  • Figures attributed to Freesky are Freesky's. Redtail has not independently range-tested or speed-tested this bike, and does not claim to have.
  • Found something wrong? Email our team — we correct pages and date the correction.
