Quality is not laughable the Giant brand says it all compare the motors sanyo (believe to be taken over by panasonic now) to dapush sanyo batterys to ?? & nexus 8 spd internal hubs & tried & tested for a year
The Giant bikes are mostly good quality, but other comparisons are not as good as they superficially appear. The battery power capacity of their twin 10 Ah 26 volt batteries is 520 Wh, the capacity of the Wisper 37 volt 14 Ah battery is 518 Wh, almost identical and lighter.
The so-called Sanyo motor is actually the old US designed Birkestrand Motorised Wheel of many years ago which Sanyo bought after Birkestrand dropped it. It's better now that the very poor regeneration feature has been discarded, but it's not up to the standards of the latest technology Dapush motor.
Panasonic's takeover of Sanyo has indeed now been finalised after many delays, but they've shown their opinion of the "Sanyo" hub motor by now designing their own advanced front hub motor instead, 3000 of which are now on trial in the Japanese market. A few of a variant have also been sold in the EU fitted in Kalkhoff bikes. It's these with which they will compete with Dapush.
