Hello to you all , have been for a ride today and after a long downhill my motor cut out after a long free wheel , its done this a few times and can get a bit annoying , is this normal, the display is still on but i have to stop riding for a few seconds ( stop at the side of the road ) and then all seems fine but obviously after going down you end up going uphill and its not what you want to happen , anyone else had this happen
