Orbea Gain - no power

[Gmac]

Hi everyone, received my Orbea Gain D40 yesterday, put it all together, charged it up to 100%, downloaded the Ebikemotion app and paired the bike in EBM mode. So far so good. Switched on, no faults, cycled through the assistance modes. All good. Ride the bike. Zero power and no motor rpm. All connections good, magnet and sensor distance in spec. HRM mode disabled. Totally at a loss. Any help welcome!
