winter commuting

Hi everyone! I am currently looking for a new bike tire for winter for me. I have pretty high expectation for it. It has to have e-50 standard as i ride fast e-bike - normal tires are getting flat too often. For last two years i was using schwalbe marthon plus mtb and those were great. 25k km...

I’m supremely new to this all and am interested in the Velec Citi+ but I can’t find reviews on it. If anyone has other recommendations I’d be open to it. I’m looking to use it for the winter in Calgary so I’d also be looking to get studded tires. Would this be an okay solution to every day...
