I've only rolled on these for about 20 miles but it's been about 50% heavy rutted ice, 25% sloppy wet but mostly clear street and 25% slippery snowy slush on top of old smooth ice.
I've only ridden a few winter seasons. I gave up biking all together in 2014 actually when went over the front and severely separated my shoulder.
But I got into electric bicycles this summer and couldn't stop!
I was hesitant to start up naturally. My last season on ice was on a Trek mountain bike with massive klondikes. I never had a problem with those.
I tentatively attempted road bike studs with klondikes again but never felt comfortable in the road bike position on ice. so those got rusty and have sat for 5 years.
My Electric Bike is a Populo V3 and the clearance for the tire didn't allow me to use my trusty old klondikes.
The hub bike co-op in Minneapolis carries the Xerxes and recommended them for my low clearance needs.
Going online I see SO MUCH HATE for these tires! I have NO idea why!
Granted a lot of those reviews are 2 years old maybe they've changed the design???
I grant you that these do not handle ice ruts lol but NO road bike tire is meant to! They're skinny! They slide down the side of ruts that's just how it is!
My electric bike can go a max 20 mph with a regular (slow) cadence.
I have these tires pumped to the minimum 35psi... Maybe that's why they grip perfectly for me??
I've grabbed my front and rear brake moderately hard on rutted THICK ice and they stop on a dime.
I would 100% recommend these tires to anyone.
Granted I've only run them a handful of miles, I've hit probably the worst road conditions you can get (I'm in MINNESOTA remember) so if you know how to handle ice, these will be fine.
As always if you grip the handlebars for dear life and don't let your tire guide you through the ice, you're already halfway to a spill.
Be safe out there!
Thank you for your feedback.
