Schwalbe
Great Schwalbe tires, no surprise. Excellent grip on hard pack fire roads and the like. But they are pretty noisy and slow on city streets and the handling is not for the road (~60m). I switched to the Super Moto-X which are quiet and quick on the streets, handle fantastic, but still have enough grip for some hard packed fun. Once things get sandy or single tracked, the Al Grounders are far superior. These are Town and Country tires, not for the Urban and Suburban'ites. FYI; both the 2.35 Al's and the 2.40 Moto-X's measured 2.25 on my wider ebike rims.
had no problems with these tubes for many many miles. I had a pinch flat (not the fault of the tube). I patched it and used it for a spare. Later after installing this spare in a tire It held air for only a few hours. I found the cause was a small hole at the base of the presta valve where the tube is reinforced at the edge . Because of the location of this hole there was no way for it to have happened during installation. I checked my other Schwalbe tube with about the same mileage and age and found an identical problem developing at the same spot. I closely examined the wheel and found nothing to have caused this. It is curious that both of the tubes had the same issue in the same exact spot. I replaced the tube with another manufacturer and so far no problem. I love the Marathon tires but a bit leery about the tubes now.
Generally, I agree with other reviews, very light, easy to install, great ride, excellent air retention.
I have ridden several hundred miles and had no flat issues on two bikes.
The valve stem is absolutely terrible!!!
Difficult to add air with a standard hand pump. valve core can easily dislodge and make the tube unusable. I don't know if I would purchase again due to the almost dysfunctional stem, but I would definitely buy if they had a quality stem, even if they were slightly higher cost over their already high price.
perfect tires for an ebike and I get groceries with these tires without any issues. The tread on the rear tire after nearly 500~ miles doesn't even seem worn and no punctures. I ride through broken glass sometimes(car accidents rarely get cleaned up in a timely manner in my area) and in grass without any issues.
The only problem is the variety of different measurements, I couldn't order the correct size tires. Now I have to order the correct size because .2 inches made my bike nearly 3mph slower(this is due to the controller on the bike not the capabilities of the tires).
