What to know before buying

Listing details to confirm

Listing details are inconsistent or unconfirmed: the page identifies the model as R004 while the product description calls it M612, describes a 26-inch commuter/fat-tire bike but gives narrower 26" × 1.95" tires, and lists battery life as 6 hours while separately claiming approximately 5.5 hours to recharge. Confirm the selected model and battery information before purchase. The advertised 35-mile range is for pedal assist, while throttle range is stated as 20 miles, both dependent on conditions.
