OPIUM will launch two new e-bikes this summer, the 6.0 and the 4.0. Both models will be capable of travelling up to 340 km (~211 miles) on a single charge, the equivalent of riding from Zurich to Geneva. The e-bikes have regenerative braking technology and an optional mounted second battery to achieve this extended range.

With a brand name like that, you know it's not made in China. ;)
I have 120 kg. Believe me this bike can NOT make 90 kilometers !
