The Pikabike S9 electric mountain bike is aimed at adults who want moped-style comfort, high peak output, and all-terrain hardware in one package. Its Walmart listing combines a 2,500W peak brushless motor, 90Nm of torque, a 48V 20Ah removable battery, full suspension, and 20-by-4-inch fat tires.
Pikabike S9 Performance Profile
Long-range battery capacity with full-suspension traction
Motor Power and Real-World Expectations
Pikabike advertises 2,500 watts of peak output and 90Nm of torque, with a maximum off-road speed claim of 33 mph. Peak wattage describes short bursts rather than continuous output, but the specification still points to brisk acceleration and stronger climbing support than a basic city e-bike. Rider weight, grade, charge level, tire pressure, wind, and controller limits determine actual performance.
A machine capable of higher speeds demands more braking distance and protective equipment. Riders should use an appropriate helmet, practice low-speed braking before traffic or trails, and confirm local e-bike classification and access rules. Some jurisdictions may not treat a 33-mph configuration as a standard bicycle.
960Wh Battery and the 100-Mile Range Claim
The removable 48V 20Ah battery stores approximately 960 watt-hours. The listing advertises up to 100 miles in pedal-assist use. That maximum will depend on a low assist setting, steady speed, cooperative terrain, and a lighter load. High-power acceleration, throttle riding, steep climbs, soft sand, cold weather, and low tire pressure will shorten range.
Even with conservative expectations, a 960Wh pack is large enough to make the S9 relevant for longer recreational rides and extended commuting. The detachable design also allows charging away from the bike and more controlled indoor storage.
Full Suspension and 20 x 4-Inch Fat Tires
The combination of front and rear suspension distinguishes the Pikabike from rigid-frame moped-style models. Full suspension can reduce repeated impacts over broken pavement, packed dirt, and moderate trail chatter. Four-inch-wide tires add traction and flotation on gravel, grass, sand, or snow, while the 20-inch diameter keeps the center of gravity relatively low.
Fat tires are not automatically ideal for every surface. They add weight and rolling resistance, and incorrect pressure can make steering vague or harsh. Tire pressure should match the load and terrain while remaining within the manufacturer’s limits.
Rider Fit, Controls, and Utility
- Steel frame: listed to support up to 365 pounds.
- Rider range: advertised for heights from 5 feet 2 inches to 6 feet 5 inches.
- Dual disc brakes: braking hardware at both wheels.
- Front and rear LED lighting: better visibility in low-light conditions.
- NFC startup: keyless access using a compatible NFC control.
- Large LCD screen: displays speed, battery level, and ride information.
- UL2849 listing claim: a relevant electrical-system safety certification signal.
Who the Pikabike S9 Suits Best
This model fits riders who prioritize battery capacity, high peak power, upright moped-style comfort, and mixed-surface ability. It may appeal to taller or heavier adults because of the broad advertised fit range and 365-pound capacity. It also makes sense for commuters who want lighting and a large display built in.
It is less suitable for anyone who regularly carries a bike upstairs, needs a lightweight pedal-first feel, or transports the bike on a rack with a low weight rating. Before buying, verify total bicycle weight, rack compatibility, assembly requirements, service options, and replacement battery availability.
Frequently Asked Questions
How fast is the Pikabike S9?
The listing claims a maximum off-road speed of 33 mph. Actual speed varies, and local rules may restrict where that performance can be used.
What battery does it use?
The S9 listing specifies a detachable 48V 20Ah battery, equal to roughly 960Wh of capacity.
Can it really travel 100 miles?
One hundred miles is the listing’s maximum pedal-assist claim under favorable conditions. Throttle use, hills, cargo, cold temperatures, and high assist levels reduce range.
Is it built for larger riders?
Pikabike lists a 365-pound capacity and a rider-height range of 5 feet 2 inches to 6 feet 5 inches. Comfort still depends on inseam, reach, and riding position.
Verdict
The Pikabike S9 stands out for its 960Wh battery, 2,500W peak motor claim, full suspension, and broad rider capacity. It is a high-spec option for buyers who want range and rough-surface capability, provided they are comfortable with the weight and responsibility that come with a faster fat-tire e-bike.
