The Assista polku Motor-Assisted Bicycle with a Higher Capacity, Long-Life Battery for Long-Distance Cycling and Added Assistance Power Now on Sale
 
Bridgestone Cycle Co., Ltd. (president: Yuji Takeuchi) will release on nationwide sale on February 03 the motor-assisted Assista Polku, which is equipped with a higher capacity 6.6Ah long-life battery to increases travelling distance and provide even more assistance power.

The recent effects of the high cost of petroleum and an increased awareness of the environment and personal health have resulted in increased popularity in motor-assisted bicycles, with demand in 2010 at 5% above the previous year (Bicycle Association statistics) and additional demand expected for 2011.

The Assista motor-assisted bicycle series have an extensive lineup of bicycles for housewives and elderly people, and last year we released the Assista polku with additional practical functions and the emphasis placed on design to provide a bicycle that can be used for commuting to school and that will appeal to fashionable housewives.
The main functions of the Assista polku include an easy-to-pedal, finely curved aluminum frame, lamp, carrier, mudguard and chain case that are color-coordinated with the frame, a lock that simultaneously safeguards the front and rear, and the Miharu-kun function that notifies the user when tire pressure is low, and it is also equipped with the latest assistance functions, including a long-life battery that can be recharged approximately twice the number of times of conventional batteries, a handlebar switch fitted with detailed displays on remaining battery power and speed, three assistance modes that can be selected in accordance with prevalent cycling conditions, and S.P.E.C.3, which provides finely-tuned assistance to match up with the gear in use.

The 2012 Assista polku mode uses a large-capacity 6.6AH long-life battery instead of the conventional 4.3Ah battery, and this has increased the distance that can be traveled on a single charge and increased the assistance power. It is fitted with a chain case that is more closely coordinated with the frame color than is usual, and a compact, ear-cleaner style stand that operates on the principle of leverage to make it easy to operate, and by concentrating on both design and practicality, we have developed a motor-assisted bicycle that is easy to use for students to have to cycle long distances every day.

< New Features of the Assista polku>
1. 6.6Ah Long-Life Battery
Using a large-capacity 6.6AH long-life battery instead of the conventional 4.3Ah battery has increase the distance that can be traveled on a single charge and increased the assistance power. This long-life battery has doubled this life-span to between 700 and 900* recharges (until replacement,) which means that the total distance that can be cycled with a single battery has been doubled, providing an economical purchase from the point of view that the extra life represents a full replacement battery with conventional models.
* This figure is a yardstick. The conditions under which this yardstick were established involve an annual recharge count of 200 cycles when used in the standard pattern at a temperature of 25 degrees Celsius. (1 cycle = a full charge after the battery has been allowed to run out.)



2. New Steel Chain Case Color-Coordinated with the Frame
Changing the chain case from resin to steel has enhanced the sense of unity with the frame color to greatly improve the sense of design.

By locking the rear wheel, the wire leading to the head of the frame simultaneously locks the handlebars to provide double security. A dimple key that is very difficult to pick has been used to enhance anti-theft performance over conventional bicycles.



9. Miharu-kun Tire Air Pressure Checker
A red indicator informs the owner that there is insufficient air in the tires and that they need pumping up. Pump the tires until the red indicator disappears for the correct pressure. Maintaining appropriate levels of air in the tires prevents punctures and increases the life span of the tires.



10. Large-capacity, Anti-rust Stainless Steel Basket

Both of the LED lamps begin to flash to provide improved visibility on both sides of the bicycle for additional safety on dark roads. The flashing will continue to approximately 40 seconds after the bicycle has stopped to guarantee safety when stopped at traffic lights. The batteries are recharged from solar panels, so replacing the batteries is not required for an extended period of time.



12. Main switch equipped with a digital meter
Battery capacity is displayed in units of 10% down until 20% remains, and then in units of 1% for the remaining 20%.

1 The assistance level represents the assistance output. Slight differences are apparent between models. *2 The light system is safe in that the light remains on even when the switch to the assistance unit has been turned off. *3 The standard pattern represents repeated cycling at a predetermined speed along two areas of flat road for 1km and up and down a hill with a 4-degree gradient for a total of 4km. The traveling distance data is based on our own data under the conditions of the battery being new, the ambient temperature being 20 degrees Celsius, the load on the bicycle being 65kg * (the total load of rider and baggage,) the surface of the road being flat and smooth, there being no wind, with the lights being extinguished, in second gear when traveling up gradients of 7.0% (4 degrees) and in third gear for all other occasions. There are cases in which traveling distance will become shorter under different conditions and in different environments. *4 The PSE rated capacities for battery capacities are listed on the right-hand side in accordance with PSE revisions (Electrical Appliance and Material Safety Law.) 6.6Ah listings represent 6.3Ah.
