Description
The Solar Sparrow is designed for riders who want a lightweight, low-maintenance, and confidence-inspiring e-bike that blends simplicity with premium performance. Weighing just 53 lbs, this step-thru cruiser is SGS certified for UL 2849 (system) and UL 2271 (battery) standards, ensuring the highest safety and reliability. With a 500W Bafang hub motor, up to 40 miles of range, and a Class 3 top speed of 28 mph, the Sparrow is built for urban commutes, recreational rides, and daily errands.
Comfort comes standard. The Solar Sparrow features a Uni-Fork suspension with 30mm of travel, paired with an SR Suntour NCX suspension seatpost to absorb bumps without unnecessary weight. A wide Velo comfort saddle and upright adjustable stem keep your riding position relaxed and ergonomic. Kenda Kwik Six 26” x 2.4” tires with reflective sidewalls add stability, traction, and visibility on city streets or light trails.
The drivetrain is a standout: a Gates Carbon Belt Drive with a single-speed setup provides quiet, grease-free operation and zero maintenance. Paired with both torque and cadence sensors, the motor delivers smooth, responsive assistance that adapts to how you pedal. A left thumb throttle adds extra boost on demand, making hills and quick starts effortless.
For safety, Tektro E350 hydraulic disc brakes with 180mm rotors deliver confident stopping power, while brake-activated motor cut-off levers enhance control. A 200-lux dual beam headlight and an integrated rear light with steady and flash modes provide all-day visibility. Internal cable routing keeps the bike clean and low-maintenance, while a full rear rack (50 lb capacity) and fenders make the Solar Sparrow practical for everyday use.
