Questions and answers

Is the FLYPKIN FK20 worth it at $513?
At $513 at Walmart as of November 4, 2026, it is cheap for a full-suspension 750W fat-tire e-bike with a passenger seat. Expect to spend time on assembly and to get less range than advertised.
How fast does it actually go?
The specs list a 20 mph maximum, while the description claims 28 mph in pedal-assist. Plan on roughly 20 mph, which is the legal limit for many Class 2 e-bikes.
What range should I expect from the 48V 18Ah battery?
The 864.8Wh battery supports a claimed 40 to 70 miles. At 20 mph with a rider aboard, expect closer to the low end, and less with a passenger or hills.
How long does charging take?
The specs give 5 hours and the description gives 7 to 8 hours with the included 2A charger. A full charge overnight covers most commutes.
Does it come assembled?
No. Assembly is required, and the box includes the battery, charger, tool kit, manual and rear seat. Budget an hour or two and check the brakes and bolts before the first ride.
Is it legal to ride on the street?
It has no NRTL listing, and rules vary by state. Check your local e-bike class limits before riding on roads or paths.
