Hi I have been riding my Gain for the last two weeks on holiday in France on their wonderful bike paths . I have not had to use power most of the time but turned it on yesterday to level 1 for some 10% climbs through the forests , the power came in after one revolution straight to full assistance and would stay on full just by turning the pedals in a very low gear and without any effort on my part flew up the hills . the app. did not show any percentage power at all . I tried in level two and three and I seemed to have more power. the power comes in and out very quickly , it was like having a throttle . Has anyone else experienced this problem. It was great fun but used the battery quickly.
