YAMAHA : URBANRUSH
The UrbanRush is designed with a foundational focus on an exciting and comfortable stoplight to stoplight ride for the urban commuter, ideal for those traveling around the St. Petersburg and Tampa downtown areas. This Power Assist Bicycle begins with a geometry and rider fit focused on balancing the often times opposing needs of an urban commuter: long-ride comfort and nimble, agile handling on tight city streets. The UrbanRush then caps it off with a well-rounded package of features, including a traditional road handlebar, for a variety of hand positions, and maximum aerodynamic efficiency while riding.
At center-stage is a Shimano Tiagra 10-speed drivetrain (with a double chainring for optimal gear range) connected to Yamaha’s center-mounted PWSeries SE motor, which offers four levels of Power Assist and a max speed support of 20mph. That is mounted to an all-aluminum frame and fork, which includes internal routing for all cables, offering a clean outside and better protection from the elements. The frame is already fitted with all mounting/wiring points for Yamaha’s option front/rear fenders and rear rack. Stopping is handled by a powerful, reliable Shimano Tiagra hydraulic disc brake system both front and rear.
The Triple Speed Sensor, integrated into the rear hub assembly, is another industry leading innovation found on the UrbanRush. This sensor is constantly taking readings of pedaling power, the bike’s rolling speed, and rpms of the pedals to better anticipate in realtime the adjustments needed to Power Assist levels to ensure a seamless, natural feeling ride through the duration of your trip. All this is handled behind the scenes, so you can pay attention to the road ahead.
The tough, ergonomic interface of the Multi-Function Meter displays all the stats you need, such as speeds, battery life, and time, and has an integrated multi-color LED indicator to allow you to see what power-assist level you are engaged in at a glance.
The UrbanRush is one of the lightest bikes in its category, only 43lbs, and does not make any compromises in quality or features to get there. Lastly, it is equipped with a LED Headlight to help keep you safe on the road.
PWSeries SE Drive Unit
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 it’s name.
Yamaha 500Wh Battery
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.
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.
Hydraulic Disc Brakes
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.
Integrated Speed Sensor
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.
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.
We equipped UrbanRush 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.
Integrated Mounts for Optional Fender and Rear Rack
The fork on UrbanRush has built-in mounting tabs for easy installation of Yamaha’s accessory front fender. The built-in bosses on the UrbanRush frame are there to accept Yamaha’s accessory rear rack to help dial in your ultimate commuter.
