      The Radio Flyer Flex e-bike is a thoughtfully designed utility bike that caters to a wide range of riders. Like Goldilocks evaluating the sizes of bears' chairs, prospective buyers may conclude that the Flex is “just right.” Its success stems from its size, frame type, ease of use, numerous safety features, and extensive accessory options.

      The Flex is a great option for those seeking an e-bike for frequent short journeys. Founded by Antonio Pasin, Jr., who sold the first Radio Flyer red wagon in 1922, Radio Flyer is now headed by his grandson, Robert Pasin, the Chief Wagon Officer. Similar to the classic wagon, the Flex is built to serve as a versatile family transport option for kids and cargo, making it enjoyable and easy to ride.

      **Radio Flyer Flex e-bike: Purpose and Ideal Use**

      Radio Flyer refers to the Flex as "the ultimate utility e-bike," an accurate characterization of its best application. However, it is not suited for off-road or dirt riding, as it lacks the necessary tires and suspension to absorb shocks from uneven surfaces.

      The Flex isn’t particularly suitable for commuting due to its speed limitation of 20 mph and its weight of 67 to 68 pounds without accessories, which can be cumbersome for many to lift or carry regularly. My test model, fully equipped with accessories, weighed 86.2 pounds.

      Do not confuse the Flex with a cargo bike such as the Pedego Cargo or the Rad Wagon 5, which are designed for carrying multiple children and heavier loads. The Flex is lighter and shorter than a typical cargo bike, with a maximum cargo capacity of 100 pounds, and a standard rear rack limit of 80 pounds.

      The rear wheel covers help prevent small feet from getting caught in the spokes. The Flex is an excellent choice for frequent short trips around town, running errands, taking a child to a friend's house, or simply enjoying rides in the neighborhood. Its variety of options for transporting small passengers, packages, or groceries enhances its versatility, embodying the true spirit of a utility bike.

      **Radio Flyer Flex e-bike: By the Numbers**

      The Class 2 Flex e-bike is equipped with a 500-watt Flight Speed rear hub motor. Though Class 2 bikes can have motors up to 750 watts, the "Flight Speed" name seems a bit optimistic. This motor delivers 53 Newton meters of torque, which is quite moderate, especially when carrying near its 330-pound maximum limit for rider and cargo combined.

      The 48-volt, 9.6-amp-hour battery fits vertically behind the seat post and stores 458 watt-hours of energy, leading to a modest range of 20 to 40 miles. You can utilize five levels of pedal assistance or a thumb throttle located by the left-side grip, but speeds cannot exceed 20 mph when relying solely on battery power. Given the Flex’s weight and gearing, pedaling without battery support may make it challenging to surpass 20 mph on flat terrain.

      The top speed adheres to Class 2 regulations, though the range estimate can fluctuate significantly based on multiple factors, including speed, acceleration, weight, terrain, and temperature. While I don’t test range due to its variability, for those hoping for nearly a 40-mile range, sticking to a low pedal assistance level and speeds of 15 mph or less is advisable. A 20-mile range may be ambitious if using the throttle liberally.

      **Electric Motor Power**

      - Power: 500 watts

      - Torque: 53 Newton meters

      - Battery: 48 volts x 9.6 Amp hours = 458 watt-hours

      - Top Speed (PAS): 20 mph

      - Top Speed (Throttle): 20 mph

      - Range: 20 – 40+ miles (variable)

      - Charging Time (0-100%): 4.5 to 5 hours

      **Radio Flyer Flex e-bike: Comfort and Convenience**

      The Flex has a modest size but isn't small, available in two frame sizes: S/M for riders from 5 feet to 6 feet tall, and M/L for those 5 feet 5 inches to 6 feet 5 inches. Both sizes support riders weighing up to 220 pounds, allowing for 100 pounds of cargo with an 80-pound maximum on the rear rack.

      Finding a comfortable seat height is straightforward, and the
