Yamaha Urban Rush Power Assist Bicycle

Details

Nothing beats the excitement of standing at the start line. For you, every stop light and crosswalk line is a chance to win again. Standing-start-sprints on your commute to work. Total concentration. Total pavement domination. No longer do you have to shave your legs to lead the pack.
• The built-in bosses on UrbanRush are there to accept Yamaha’s accessory rear rack to help dial in your ultimate commuter.
• At the heart of UrbanRush is Yamaha’s awesome PWSeries SE center mount drive unit. Integrated to the bottom bracket, the drive unit provides a low center of gravity for exceptional handling. The four levels of power assist assure UrbanRush lives up to its name.
• Large ergonomic control switches and easy to read LCD multi-function display are designed to keep your focus on what’s ahead. The main LCD interface allows you to choose from a full suite of functions; Speedometer, average speed, maximum speed, odometer, trip meter, battery capacity, battery range, cadence, clock and stopwatch.
• Shimano Tiagra hydraulic disc brakes with 160mm center lock rotors ensure strong, confident braking in all conditions. Speaking of all conditions, UrbanRush’s fork has mounting tabs for easy installation of Yamaha’s accessory front fender.
• Shimano’s durable 10-speed Tiagra groupset handles UrbanRush’s shifting duties. The double chainring (50/34T) ensures optimum gear range to conquer any climb your commute presents with ease.
• The UrbanRush is equipped with a powerful LED headlight to help guide the way. The headlight’s on/off button is built into UrbanRush’s multi-function display housing for easy access while riding.
• The fork on UrbanRush has built-in mounting tabs for easy installation of Yamaha’s accessory front fender.
• Exclusive to Yamaha Power Assist Bicycles is a speed sensor engineered into the rear hub. Our speed sensor recognizes the slightest change in bicycle speed and helps adjust motor input to deliver a smooth and natural power assist feel for the ultimate ride experience.
• Yamaha’s 500 Watt-hour Lithium-ion battery pack provides reliable & long lasting energy to power your rides. When it’s time to replenish, you can charge the battery pack on or off UrbanRush using the Yamaha high speed charger.
