The 2,160 Wh Single-Motor Fat-Tire — Built for Range, Not for Roads The Alaska Pro M-520 is the longest-range single-motor fat-tire bike in our catalogue. One rear hub motor. 4,000 W of peak power. A 48V 45Ah dual battery system that totals 2,160 Wh — 50% more energy than the dual-motor AWD Ranger Plus M-540, and roughly three times the capacity of the standard 720 Wh fat-tire benchmark. For riders who do not need all-wheel drive and would rather trade a second motor for a battery they cannot exhaust in a day, Freesky built exactly that. The bike weighs 90 lbs — 16 lbs lighter than the dual-motor Ranger Plus despite carrying more battery. That is the trade Freesky made: skip the front hub motor and its associated harness, controller pair, and copper, and reinvest the weight budget into cells. The result is a bike with the practical range of a dual-battery hunting machine and the simpler mechanical layout of a conventional rear-drive eBike. One motor to service. One drivetrain to maintain. Two batteries that swap in and out for indoor winter storage or extended-day swaps. The honest caveat: this is a step-over frame with a 28.7″ standover. You swing a leg over a top tube to mount. If hip mobility, knee flexibility, or balance at standstill is a concern, the step-thru Ranger Plus M-540 is the better choice — it costs more, weighs more, but you step through it. The Alaska Pro is for riders who want maximum range and power without the AWD complexity, and who can mount a traditional fat-tire frame. Free Canada-wide shipping.

Two adults recommended for unboxing — the bike is 90 lbs in the box and the dual-battery configuration adds extra centre weight. Final assembly takes 30–45 minutes: Unbox and inventory all parts against the printed checklist Install the front wheel and align the brake disc between the caliper pads Mount and align the handlebars, tightening stem bolts evenly Thread in both pedals (right side clockwise, left side counter-clockwise) Adjust the seat height within the 30–38″ range; the alloy 30.9 × 350 mm seat post slides freely once the clamp is loosened Insert both batteries into the frame mounts and lock with the included key Charge each battery fully before the first ride — expect roughly 6 hours for the 18Ah pack and 9 hours for the 27Ah pack on the included 3A charger when charged one at a time Power on, test both brakes, run through all 5 PAS levels and confirm throttle response before your first real ride Printed Owner’s Manual: Included in the box. Covers assembly, display operation, PAS levels (0–5), battery removal and indoor charging procedures, brake bedding-in, and maintenance schedules. Reviews & Walkthroughs The Alaska Pro M-520 is new to the Freesky catalogue. Independent long-form reviews are still being filmed. If you want a personal walkthrough — battery removal, PAS feel, brake response, frame fit at your height — call Zeus eBikes at 1-866-938-7580 and we will set up a live video walkthrough on the actual bike from our warehouse before you commit. That offer stands for every bike we sell. For the underlying single-motor fat-tire experience and battery handling that this platform shares with the broader Freesky range, the M-540 platform assembly guide is a useful reference: Why 2,160 Wh Changes Everything About Range Anxiety The number is the point. 2,160 Wh is not a marketing spec — it is a category leap. Most fat-tire eBikes ship with 672–720 Wh. Premium dual-battery hunting platforms ship 1,440 Wh. The Alaska Pro arrives stock with 50% more usable energy than even those dual-battery flagships. At realistic Canadian mixed-terrain consumption of 15–20 Wh per kilometre, the math reads: Riding Profile Wh/km Practical Range Low PAS, flat pavement, summer ~10 Wh/km ~210 km Mixed PAS, rolling terrain, summer ~15 Wh/km ~144 km High PAS, gravel/sand, summer ~20 Wh/km ~108 km Mixed PAS, winter (−10°C, 25% capacity loss) ~15 Wh/km ~108 km Throttle-only, full power ~25–30 Wh/km ~72–86 km Freesky publishes a 98–175 mile (158–282 km) claim. The high end of that figure assumes very low PAS, flat tarmac, light rider, and warm temperatures — conditions that rarely line up in real Canadian riding. Our practical estimate above is what the bike will actually deliver across the conditions most riders see. Even our most conservative number — 108 km on high PAS gravel — is longer than the entire range of a typical 720 Wh single-battery fat-tire. The dual-battery layout is a separate practical advantage from the raw capacity. Each pack — 18Ah and 27Ah — is independently removable. You can carry one inside for indoor charging through a Canadian winter while the other stays in the bike. You can swap a depleted pack for a charged one mid-ride. You can replace one battery in five years without binning the second. Single-battery platforms force an all-or-nothing replacement when degradation starts. For a full breakdown of how watt-hours translate to real-world range across Canadian terrain and weather, see our long-range eBike guide → 4,000W from One Rear Hub — What That Actually Means Single-motor 4,000W peak is a different proposition from dual-motor 4,000W AWD. The Ranger Plus splits 4,000W across two hub motors, gaining traction at the cost of weight and complexity. The Alaska Pro concentrates 4,000W peak in one rear hub — the rider feels it as a single, immediate hit of acceleration from the back wheel, the way a motorcycle delivers power. The 160 N·m of torque arrives at the rear contact patch in one place, not divided. The trade-off is traction on loose surfaces. When the rear wheel breaks loose on wet grass, packed snow, or loose gravel, a single-motor bike fishtails or spins where an AWD bike claws forward. The Alaska Pro’s 4″ fat tires and the bike’s weight over the rear axle help, but they cannot replicate dual-motor mechanical traction. If your riding regularly involves loose surfaces at the limit of grip — deep snow, sand at speed, hill-climbs on wet ice — the Ranger Plus M-540 is the more honest answer. If your riding is fast over packed surfaces — gravel roads, hard-packed snow, dry trails, pavement — the Alaska Pro delivers power without the dual-motor weight penalty. Top speed: 40 mph (64 km/h) on PAS, 20 mph (32 km/h) on throttle alone. Default factory limiting is set lower — adjustable through the display. At 4,000W combined peak this is unambiguously off-road equipment in Canada. See the legal section below. For more on how single-motor wattage compares across the catalogue, see our wattage guide → Key Features 4,000W Peak Rear Hub Motor — 160 N·m Torque — Brushless rear hub paired with a 48V/30A controller. Acceleration is immediate from a stop; the 160 N·m peak delivers usable climb force on grades that bog smaller motors. Power delivery is throttle-direct — what you twist is what you get. Wattage guide → 48V 45Ah Dual Battery — 2,160 Wh Total — Both Removable — 18Ah pack + 27Ah pack, mounted in the frame, each independently removable for indoor charging. The largest stock battery configuration anywhere in our catalogue. Real-world range across Canadian conditions: 108–210 km summer depending on PAS and terrain; ~108 km mixed winter at −10°C after 25% cold-weather capacity loss. The dual-pack design means winter degradation does not strand you — one indoor-warmed pack will get you home even if the second is cold-soaked. Long-range guide → UL2849 Certified by TÜV — The complete eBike electrical system — controller, motor, wiring, BMS interaction — is independently tested and verified to UL2849 by TÜV. This is the system-level safety standard most eBikes in this category do not carry. UL2271 battery-level certification is not currently listed on Freesky’s published materials — we state only what we can verify. Full Suspension — Front Lockout Fork + Rear Shock — The front fork is a downhill-rated coil unit with rider-adjustable preload and a lockout for efficient pedalling on pavement. The rear shock handles trail chatter, drops, and the frost-heaved tarmac that defines Canadian spring. Combined with 4″ tires, the system stays composed at the bike’s 40 mph ceiling on rough surfaces where a hardtail would buck. 4-Piston Hydraulic Disc Brakes — 180 mm Rotors — Four pistons per caliper deliver substantially more clamping force than the two-piston units standard on most eBikes in this class. At 90 lbs of bike, 400 lbs of payload, and 40 mph top speed, four-piston brakes are the minimum responsible spec. Consistent feel in rain, mud, and packed snow — no cable stretch, minimal fade on long descents. 26″ × 4.0″ Fat Tires — Four inches of contact width floats over sand, snow, mud, and loose gravel. The 26″ wheel diameter rolls over obstacles more smoothly than smaller fat-tire setups and gives the Alaska Pro a stable ride height. Fat tire guide → Colour LCD Display — Shows speed, battery percentage for each pack, PAS level (0–5), trip mileage, odometer, and headlight status. Walk-assist mode (6 km/h) for pushing the bike alongside, cruise control on the throttle, and a USB output port for charging phones or accessories on long rides. Integrated 2,500-Lumen Headlight with Horn — Most eBike headlights run 200–400 lumens — enough to be seen, not enough to see by. The Alaska Pro’s 25W / 2,500-lumen unit throws a real cone of light for genuine after-dark riding on unlit roads or trails. The integrated horn replaces the standard bell — substantially louder, useful on shared paths where pedestrian alerts at speed matter. Shimano 7-Speed — KMC Chain — Seven mechanical gears layer on top of five PAS levels. Low gear for comfortable pedalling on climbs; high gear for efficient cruising. KMC chain is globally serviceable at any bike shop. The 7-speed is functional, not refined — honest take below. 400 lb Payload — IPX6 Weather Sealing — The electrical system is rated IPX6 for water-jet resistance, which means snow, rain, slush, and trail spray are not bike-killers. The 400 lb payload accommodates riders up to ~280 lbs with 120 lbs of cargo margin for panniers and gear. Heavy rider guide → Heavy-Duty Adjustable Aluminium Kickstand — A 90 lb bike on uneven ground needs a real kickstand. The Alaska Pro’s is rated for the full weight and length-adjustable for parking on slopes. Three Frame Colours — Black, Blue, and Green. All three use the same 6061 aluminium step-over frame. Everything Included Ships ~85% pre-assembled. Expect 30–45 minutes for final setup: front wheel, handlebars, pedals, seat post, battery installation. Two adults recommended for unboxing — the bike is 90 lbs in the carton. Freesky Alaska Pro M-520 eBike — Black, Blue, or Green 48V 18Ah lithium-ion battery pack — removable 48V 27Ah lithium-ion battery pack — removable 3A US-standard smart charger Colour LCD display with USB output (pre-installed) Integrated 2,500-lumen LED headlight with horn (pre-installed) Rear LED tail light (pre-installed) Heavy-duty adjustable aluminium kickstand (pre-installed) Pedals Battery keys — one set per pack Assembly tool kit Printed owner’s manual Not included: Rack and fenders are not included with the Alaska Pro M-520 — if you need them for cargo carrying or wet-weather riding, budget for aftermarket fitment. This is a notable difference from the Ranger Plus M-540, which ships with both. Free Canada-wide shipping — Zeus coordinates delivery to your door. Dimensions & Fit Guide Frame Geometry Frame Type Step-over — 28.7″ (73 cm) standover Total Length 76.5″ / 194 cm Wheelbase 47.4″ / 120 cm Total Height 44″ / 112 cm Wheel Diameter 26.7″ / 68 cm Recommended Rider Height 5’6″–6’8″ / 168–203 cm Recommended Inseam 27″–35″ / 69–89 cm Fit notes: The 28.7″ standover means riders need at least a 28″ inseam to clear the top tube comfortably at a standstill. Riders at the bottom of the 5’6″ height range will be at the limit — consider sitting on the bike before committing if you are short-legged for your height. The 47.4″ wheelbase is long for a 26-inch-wheel bike; combined with the 90 lb mass and fat tires, this creates a planted, stable ride that resists crosswinds and absorbs road irregularities. The trade-off is manoeuvrability — tight U-turns require more room than a lighter, shorter-wheelbase bike. At 6’8″ the Alaska Pro is one of the very few fat-tire bikes in our catalogue that fits tall riders comfortably without a frame size upgrade. The 90 lb / 2,160 Wh Reality — What This Bike Asks of You 90 lbs is heavy by general eBike standards but light for what this bike is. Most eBikes weigh 55–75 lbs. The Alaska Pro is 90. The Ranger Plus M-540 with similar peak power is 106. The 90 lb figure with 2,160 Wh of battery on board is the practical headline — Freesky kept the weight down by skipping the front motor, which translates to a bike that’s easier to lift, push, and load than its dual-motor counterpart. That said, 90 lbs is still 90 lbs: Ground-level or garage storage is strongly recommended. Up a flight of stairs is a serious two-person job. The dual battery system helps here: pull both packs (combined ~7–8 kg / 15–18 lbs) and the bike drops to roughly 75 lbs — manageable for short single-person lifts. Vehicle loading should use a ramp. Lifting 90 lbs onto a truck bed or rear-mount rack without a ramp risks back injury and brake-lever damage. Bench-loading ramps are an inexpensive one-time purchase from any hardware retailer. Once you are riding, the weight disappears. 4,000W of peak rear-hub power moves 90 lbs like it is not there. The low centre of gravity (heavy frame + 26-inch fat tires) makes the bike feel planted and stable at speed, not top-heavy. In crosswinds, on gravel, over rough pavement — heavier bikes track straighter. If weight matters more than range, single-motor step-thrus in our Step-Thru collection weigh 50–65 lbs and use smaller batteries. If you need the maximum traction insurance that AWD provides and can carry 16 more pounds, the Ranger Plus M-540 is the answer. The Alaska Pro is the right answer when range and power matter more than either of those. The Honest Take — What We’d Change Zeus sells this bike because 2,160 Wh of stock battery on a 90 lb frame at 4,000W peak does not exist anywhere else under our price ceiling. That does not mean it is perfect: Speed sensor, not torque sensor. The Alaska Pro uses a cadence-style speed sensor — it detects whether you are pedalling, not how hard. Assist is binary per PAS level: on when spinning, off when stopped. No proportional, natural-feeling pedal response. For throttle-dominant off-road riding this is functional. For pathway riding near pedestrians where precise speed control matters, the difference shows. The Eunorau Hunter X7 offers a genuine Bafang mid-drive torque sensor; the Velotric Nomad 2 has a SensorSwap system that toggles between torque and cadence on the fly. Torque vs cadence explained → UL2849 only — UL2271 not listed. Freesky publishes UL2849 (system-level certification by TÜV) but does not currently list UL2271 (battery-level certification). UL2271 covers cell-level thermal runaway, impact, and overcharge testing independently from the system. The Velotric Nomad 2 carries both UL2849 and UL2271. If battery-cell-level certification is a hard requirement for you — condo insurance, building bylaws, personal preference — verify with your insurer before purchasing. 7-speed Shimano is undergunned for a 4,000W machine. A bike with a 40 mph PAS ceiling and 160 N·m of torque deserves 8- or 9-speed gearing. The Eunorau Hunter X7 runs Shimano 9-speed. The Taubik Westridge 4T Off Road runs Shimano Acera 8-speed. Both are more appropriate for this power class. The 7-speed feels overgeared at low speed and undergeared at top speed — you ride on PAS and throttle, not the cassette, more than you should. 3A charger is too small for a 45Ah pack. Freesky claims 6–8 hours charge time. At 3A with one 45Ah pack, the math is closer to 15 hours full charge from empty. The 6–8 hour figure is achievable if you remove one pack, charge them separately, and stage them — 6 hours for the 18Ah, ~9 hours for the 27Ah. Budget for an aftermarket 5A charger if same-day multi-charge cycles matter to you. The Velotric Nomad 2 ships with a 3-hour fast charger from the factory at this price point — the Alaska Pro should match it. No included rack or fenders. At this battery size and the off-road positioning, an unpaved-day rider expects splash protection. The Ranger Plus M-540 includes both. The Velotric Nomad 2 includes fenders. Plan for an aftermarket rack and fender set, or buy from the Zeus accessories collection. No turn signals or NFC security. At 90 lbs and 40 mph, the Alaska Pro has the road presence of a moped. Turn signals are not included — aftermarket handlebar-mount signal kits are inexpensive and worth fitting. NFC anti-theft locking is not included either; rely on a heavy chain lock and indoor battery storage. The Velotric Nomad 2 has integrated turn signals and Apple Find My / Android Find Hub for tracking. Not a federally classified power-assisted bicycle in Canada. The Alaska Pro’s 4,000W combined peak and 40 mph PAS ceiling exceed Transport Canada’s 500W nominal / 32 km/h limits for a Power-Assisted Bicycle (PAB). This bike is sold for off-road trails, private property, motorised-vehicle-permitted routes, and Crown land where local rules allow. It is not for public roads, dedicated bike lanes, or multi-use pathways. Confirm local rules before riding off your own property. Trade-offs acknowledged: a 90 lb single-motor fat-tire with 2,160 Wh of removable battery, full suspension, 4-piston brakes, and UL2849 system certification under the price tier of Velotric’s smaller-battery Nomad 2 is a genuine value proposition. The Alaska Pro is the right bike for the rider who has decided range, power, and battery flexibility matter more than AWD or integrated security tech.

Optional Zeus extended support plans available at checkout Who Buys the Alaska Pro M-520? Rural riders, acreage owners, and property workers — 108–210 km of summer range means you check fences, ride to the back of the property, drive to town, return, and still finish the day with battery to spare. The 400 lb payload handles rider plus gear plus tools. The IPX6 weather sealing handles the spring mud, summer dust, and fall rain that define rural Canadian riding. Hunters and Crown-land riders — 2,160 Wh is enough to ride out, hunt, and ride back without thinking about charging. Single-motor simplicity means fewer connectors, fewer harnesses, and less to fail in the field. Quiet hub-motor operation (mid-drives whirr, hubs hum) helps on approaches. Long-distance trail and gravel riders — If you ride 80–150 km on dirt and gravel in a day and want to do that without battery swapping or PAS rationing, the Alaska Pro’s 2,160 Wh is the difference between riding freely and riding while watching the percentage. The 4″ fat tires and full suspension keep that day comfortable. Heavy riders up to 400 lbs — 400 lb payload is generous. A 280 lb rider still has 120 lbs of cargo capacity. The 4,000W peak power and 160 N·m torque deliver real climbing performance for heavier riders where smaller-motor bikes bog down. Heavy rider guide → Canadian winter riders — Fat tires + full suspension + IPX6 sealing is the right configuration for November–March. The dual battery lets you carry one pack inside through the night and swap it in for a cold-weather start. Even with 25% capacity loss at −10°C, the bike still delivers ~108 km of mixed-terrain range — longer than most warm-weather single-battery fat-tires. Winter guide → Throttle-first off-road riders — If you primarily ride on throttle rather than pedal assist, the cadence-vs-torque sensor distinction matters less. 4,000W on the throttle is genuinely fun. Pedal assist vs throttle guide → Tall riders (6’2″–6’8″) — The 47.4″ wheelbase, 38″ max seat height, and 35″ max inseam accommodate riders the smaller-frame fat-tires cannot. If you have struggled to find a fat-tire that fits comfortably, the Alaska Pro likely will. Who it is NOT for: Riders with hip or knee mobility constraints — The 28.7″ standover requires swinging a leg over a top tube. If you cannot or prefer not to, the step-thru Ranger Plus M-540 or one of the bikes in our Step-Thru collection is the better choice. Riders who need AWD traction — If your riding involves loose surfaces at the limit of grip — deep snow, sand at speed, ice — a single-motor hub will fishtail where a dual-motor AWD will pull through. The Ranger Plus M-540 is the right answer for that use case. Riders who want torque-sensor pedal feel — The Eunorau Hunter X7 offers a genuine Bafang mid-drive torque sensor; the Velotric Nomad 2 offers SensorSwap (torque + cadence). Street commuters in Canada — At 4,000W peak the Alaska Pro is off-road only. If you need a federally classified PAB for bike lanes and pathways, see the Urban eBike collection. Apartment dwellers above ground level — 90 lbs of bike up multiple flights of stairs is impractical. The dual-battery removal helps, but you are still lifting a 75 lb frame.

The 4,000W peak motor and 160 N·m torque sit at the top of this group. Full suspension and 4-piston brakes are spec advantages over the Westridge (hardtail, dual-piston) and Hunter X7 (hardtail). If raw range and power matter most, this is the answer. Choose the Velotric Nomad 2 if: You want the best technology and electronics in this group at a comparable price point. Dual UL certification, SensorSwap dual-mode sensor (torque + cadence), integrated turn signals, 500-lumen auto-sensing headlight, Bluetooth display, cruise control, walk mode, step-thru frame option, and a 505 lb payload — the highest in this comparison. 75 lbs makes it 15 lbs lighter than the Alaska Pro. Trade-off: 705.6 Wh is roughly one-third the Alaska Pro’s battery, and 90 N·m torque is well below the Alaska Pro’s 160 N·m. The Nomad 2 is the better commuter; the Alaska Pro is the better long-day backcountry bike. Choose the Taubik Westridge 4T Off Road if: You want a Canadian-brand build with a 1,000W Bafang geared hub motor and the widest tire in this group — 4.8″ Maxxis Minion fat tires (versus 4.0″ everywhere else). The torque sensor delivers cleaner pedal feel than the Alaska Pro’s cadence sensor. Trade-offs: hardtail (no rear suspension), dual-piston brakes (versus 4-piston), 286 lb payload (substantially lower than the Alaska Pro’s 400 lbs), and smaller battery. Strong choice for riders who prioritise pedal feel and tire grip over absolute range and power. Choose the Eunorau Hunter X7 if: You want whisper-quiet Bafang mid-drive power with a torque sensor and the option to expand to dual 1,440 Wh. Mid-drive efficiency translates 160 N·m through 9 Shimano gears for devastating climbing torque. The trade-offs: hardtail (no rear shock), no UL2849 or UL2271 certification listed, base battery (720 Wh) is one-third the Alaska Pro’s stock capacity, and the second-battery upgrade adds cost. Better for hunters and trail riders who value drivetrain quality and pedal feel over raw battery capacity. Frequently Asked Questions Is the Alaska Pro M-520 street-legal in Canada? No. The 4,000W peak motor and 40 mph PAS top speed exceed Transport Canada’s 500W nominal / 32 km/h limits for a federally classified Power-Assisted Bicycle. The bike is sold for off-road trails, private property, Crown land where local rules allow, and routes that permit motorised vehicles. Confirm local trail and Crown-land rules before riding. What is the real-world range I can expect in Canada? Practical Canadian range from the 2,160 Wh dual-battery system: ~210 km on low PAS over flat pavement in summer, ~144 km on mixed PAS over rolling terrain in summer, ~108 km on high PAS over gravel or sand in summer, and ~108 km mixed riding in winter at −10°C after typical 25% cold-weather capacity loss. Freesky’s official 98–175 mile (158–282 km) claim sits at the optimistic end of that envelope and assumes ideal conditions. Long-range guide → Are reviews available for this bike? The Alaska Pro M-520 is a newer addition to the Freesky catalogue and independent long-form reviews are still being filmed. If you would like a pre-purchase live video walkthrough of the actual bike from our warehouse, call us at 1-866-938-7580 and we will set one up — the offer stands for any bike we sell. Does it have a torque sensor? No. The Alaska Pro uses a cadence-based speed sensor. Pedal assist delivers a fixed power level for each PAS setting (0–5) regardless of how hard you push the pedals. For throttle-dominant off-road riding this is functional. For pathway and shared-trail riding where proportional speed control near pedestrians matters, a torque sensor delivers noticeably better feel. Torque-sensor alternatives in our catalogue: Eunorau Hunter X7 (Bafang mid-drive torque) and Velotric Nomad 2 (SensorSwap toggles torque and cadence). Sensor guide → How heavy is it, and how do I handle it? 90 lbs. Practical reality: (1) Ground-level or garage storage is strongly recommended — carrying it up stairs is a two-person job. (2) Use a loading ramp for truck or van transport — lifting 90 lbs without one risks injury and brake-lever damage. (3) Both batteries are removable: pulling both drops the bike to roughly 75 lbs, which is more manageable for single-person lifts. (4) The 47.4″ wheelbase makes the bike stable and planted at speed but requires more room for tight U-turns at walking pace. What rider heights fit this bike? Freesky rates it for 5’6″–6’8″ (168–203 cm) with a 27″–35″ inseam. The 28.7″ standover requires at least a 28″ inseam to clear the top tube comfortably at a standstill. Riders under 5’6″ or with short legs for their height should consider a step-thru alternative. At 6’8″ the Alaska Pro is one of the few fat-tire bikes that fits very tall riders without needing a frame size upgrade. What is the warranty on the bike? Every Alaska Pro M-520 ships with a 1-month Zeus eBikes limited warranty (Canadian-handled), plus the Freesky manufacturer warranty: 24 months on the motor, battery, and controller, and 12 months on other parts. Wear-and-tear items (tires, brake pads, chains, grips, saddles) and damage from misuse or unauthorised modifications are not covered. Optional Zeus extended support plans (1, 2, 3, or 5 years) are available at checkout for additional remote diagnostic and support access. What certifications does the battery have? UL2849, verified by TÜV. UL2849 certifies the complete eBike electrical system. Freesky’s published materials do not currently list UL2271 (battery-cell-level certification). If UL2271 specifically is a building-bylaw, insurance, or personal requirement for you, the Velotric Nomad 2 carries both UL2849 and UL2271 at a comparable price point. How long does each battery take to charge? With the included 3A US-standard smart charger and packs charged one at a time: roughly 6 hours for the 18Ah pack and roughly 9 hours for the 27Ah pack. Freesky’s 6–8 hour total charge time figure assumes this sequential charging approach. For multi-ride days, an aftermarket 5A charger can cut each pack’s charge time by roughly 40%. Can I finance this bike? Yes. Zeus eBikes offers Canadian financing options at checkout. See our eBike financing guide for the available lenders, eligibility requirements, and how payment terms are structured. Do I need a license, insurance, or a helmet to ride this? Because the Alaska Pro’s 4,000W peak output and 40 mph top speed exceed the federal Power-Assisted Bicycle limits, on-road use is not covered by PAB exemptions. Off-road land-use rules vary by province, by municipality, and by individual park or Crown-land area. Helmets are mandatory on all eBikes in every Canadian province where eBike use is regulated; full-face or motocross-style protection is recommended at this power class. Confirm specific rules with your provincial transport authority and any private trail or land owner before riding. Zeus eBikes Canada — Free Canada-wide shipping.
