A2B Octave Review
The A2B Octave is a high quality bike with a solid, durable feel. It is an upgraded version of the iconic A2B Metro, one of the first mainstream stylish electric bikes. In 2011 A2B merged with F4W and is now a part of the Hero Eco group. The re-released and renamed “Octave” features improved tires, better positioning on the speedometer and key slot and quieter chain guide.
Driving the Octave is a gearless 500 watt rear hub motor that is nearly silent! This bike comes with one battery labeled as “A” but can accommodate up to two batteries for increased range. The second battery fits beneath the rear rack and is labeled as “B”. To switch between batteries you just turn the key from A to B.by
