Smart Mercedes bike sprocket

I have just acquired a Smart Mercedes ebike. The only problem is that the drive sprocket slips round when pressure is applied by a pedal or by hand. It looks as though it might be a simple fix. Bike shop has had a quick look, 1 gear engages, but other 2 slip or engage sometimes The advice is to check You Tube, but can' find any videos that dismantle the hub gear side? The motor is OK. Any help would be much appreciated. Rob
