The Propella 9S Pro V2, unveiled late last year, is gaining attention as one of the few low-cost torque sensor-enabled electric bikes. The new model has officially started shipping to customers, offering a unique feature highly praised by electric bike riders who prioritize pedaling over using the throttle.
Torque sensors, commonly found in European e-bikes, provide a more intuitive and natural pedaling experience than the simpler cadence sensors often used in lower-cost e-bikes in the US. While most US e-bikes with torque sensors are typically priced above $2,000, the Propella 9S Pro made headlines last year for offering a torque sensor at $1,199.
The Propella 9S Pro V2 comes with significant upgrades, moving away from the minimalist design that the brand is known for. It introduces two frame style options, including Propella’s first-ever step-through design, and features an integrated frame battery, enhancing aesthetics and complying with safety standards.
The 360 Wh capacity battery, while smaller compared to industry standards, provides a maximum range of 55 miles on lower power pedal assist.
Powered by a 500W peak-rated rear hub motor, the e-bike reaches a top speed of 20 mph, adhering to the legally allowable limit for Class 1 e-bikes. Including a torque sensor enhances the pedal-assist experience, delivering power based on the rider’s pedaling effort.
Additional features contributing to the bike’s value include a 9-speed drivetrain, an integrated headlight running off the main battery, an adjustable stem, a color LCD screen, fenders, a high-power charger for three-hour recharges, and hydraulic disc brakes.
While lacking suspension, the 2″ tires provide a cushioning effect for a more comfortable ride. The Propella 9S Pro V2 showcases how affordable electric bikes can incorporate advanced features, making them more accessible to a broader audience.
