yes it is so interesting since our bicycle giant maker - Giant moved to ebikes long time but they never even say how big is their battery pack. I just can't understand how company that is so big can hide all of their specs to the customers. The unkown battery capacity is something that would certainly put me off of Giant - regardless how comfy it is.

Look forward to hear your views on Giant
The Giant Freedom uses 10 Ah lithium batteries for their carrier mounts, so 20 Ah for the twin battery system. Despite this the range is not exceptional, 40 to 50 miles in average territory being common. The same was true for it's predecessor the Twist 1, but the Twist 2 used twin 9 Ah NiMh batteries.

The motor on all these was originally the "Motorised Wheel", a regenerative system from the Birkestrand Corporation of the USA, but the design was sold to Sanyo of Japan where Giant got it from. In the Twist 1 and 2 it kept the regeneration so had no motor freewheel, but the resulting drag was unpopular and the regen didn't work well anyway. The Freedom models have lost the regeneration and gained a freewheel and are the better for it, more powerful and able to realise the benefits of their over 400 watts peak power fully.

Giant might not give the information, but I do! :)

thanks Tony,

As usual you are the star that solves all the issues... but te normal consumer like me hiding all this info is just taking my confidence away from this company. What volatge is teh motor, what capacity, what range - promoting electric bikes from the wrong side. These are the features I'm the most interested in!!!

I agree Alex, their "for the average consumer" stance isn't necessary. For decades the motor industry have managed to provide full technical information in ways that don't scare off the non-technical, so there's no excuse for e-bike companies failures in this respect.
