Work great and seem like they will last for a long time!
Super durable tires and tubes. I have limited time on them so far cause I cooked my motor but upon install the tubes were noticeably higher quality than the oem ones that I was taking out (that I had patched extensively lmao). Tread seems solid and looking forward to getting 1000's of miles out of these like others have done. Once my 5000w motor shows up that is. Will see if I can make them do a burn out with that....:)

The guy at the bike shop said they are good tires.
Yes... A good choice. I wore out the Original knobby tires and replaced them with these. Traction is just as good and I'm sure I'll be less prone to flats. The guy at the bike shop said they are good tires.

Nice road tires for my electric cargo trike.
The tires are a good price if you buy the set of 2. I have a trike so I had to pay more for a single tire for the front. These 2 tires came in a box and had been folded in half and then rolled up and bundled tightly with large zip ties. I had to unbox them and unfold them and let them sit for a day to somewhat return to normal shape, but even then they were not perfectly round until after I got them on the rim and inflated the inner tube. The single tire that is the same size\brand was shipped in a large but thin box (24x24x2) and that tire was not folded in half and rolled up so it was able to be installed straight out of the box. So keep in mind they will need a day (or several) after unboxing and unfolding them to allow the tire to return to a round shape, otherwise it would be a real pain to try and fit them on the rim. Has only been a few days since I put them on, but they are working great so far.

Fits the X Trail Bandit Pro E Bike
These tires and inner tubes fit the X Trail bandit pro stock rims: 20"X4" They seem very sturdy, rugged and are built for moped style e bikes, motorcycles and mopeds. I'm sure they work for other e bikes that are more cafe style. The stock CST BFT tires on the bandit x trail pro are more like mountain bike tires, and these yunsum tires are more like moped/motorcycle tires in terms of build and quality. I suspect they will last a very long time and will perform great in light off road applications where thorns are an issue. Definitely get these if you want to do off road riding on your e bike.

Strong durable tires.
A heavier thicker tire design that will slow your bike down about 2to3 mph and make the battery work harder. With that in mind the tire really grabs the road under all weather conditions. A small sacrifice for speed and range but to be safer out there on the roads and sidewalks equals more value in the end. Great tires I expect to get about 3,000 miles out of these for sure. Great purchase.

Great Performance for the money
Do not hesitate to order these. The tires are of high quality and really grip the road. I was due for an upgrade for a long time and started looking at cheaper options. Decided to treat myself to these for my ebike and oh boy I'm glad I did! They are like motorcycle tires, super tough and include some great inner tubes that are thick. They are not loud but audible, though super smooth on the streets. Rides great over potholes and really grips the road. Do not sleep on these. Edit: They come out of the box unfolded so you won't have to deal with creases!

Better than the original tires.
Far superior to the original tires and much more stable in turns.

Update 2nd flat This is a reaction tire, not so much puncture protection
*update typed after everything you will read below* This tire is good for traction not so much puncture resistance, got my second flat today, don't think I've had these a month. Luckily I had some slime and a small pump, then I started Praying to YHWH and out of nowhere, in the rain and the late night darkness miles from home a guy comes up to me while I'm praying and says he is a long ebike owner and he has a portable air compressor 🤯 the odds. Decent traction in light snow and rain , not and I repeat not good for puncture resistance. 🚨 If you are going to use these for a long ride please carry tube slime sealant (The green one) on 80z per tire. I'mI got this tire to replace the wobbly death trap tires that was on the bike before. I was going to leave a terrible review because I got a flat 2 days after installing them. But what punctured them was a sheet rock screw that happened to be in the street. But before that they were solid, and after that to this day they are still solid. They surprised me in lite snow and in light drizzle with wet streets. Both snow and rain I was not going full speed. On wet streets I wasn't that confident only because I don't fully know these tires fully yet. But I do know they performed 10x better than most tires I had before on wet roads, and had decent traction in light snow and on gravel. Keep at a high psi, I even accidentally did 35 psi instead of 30 psi and that's when they performed best in my opinion. I'm not telling you to do anything I did, I'm just letting you know how it worked for me. Riding around promoting my movie (THE ADVENTURES OF DIDDY) 🤯 ON YouTube

Ho acquistato 4 copertoni YunSCM 2Pcs Heavy Duty 20 pollici per 2 bici da 750w Inizio con le note dolenti che riguardano il montaggio, questo risulta molto difficoltoso nella centratura in quanto basta anche una lieve asimmetria per sentirla molto forte nella guida, tipo di sentire le ruote ovali. Ciò non mi era capitato con i precedenti pneumatici di altre marche, anche se arrivati piegati. Detto ciò, dopo aver fatto 500 km confermo quanto descritto nelle info prodotto, davvero eccellenti. Tenuta in curva da moto, ottimi anche sull'asfalto bagnato, nel fango vanno molto meglio degli originali tassellati, su strade bianche ti concedono un po' di piega, consumi non aumentati (forse 4 o 5 im in meno). Riguardo alla velocita max rispetto a prima cala di 5 kmh, ma non sono reali, in quanto essendo di diametro maggiore falsa il tachimetro, mentre al tachimetro gps e quello della mia vettura rimane invariato. Nonostante la possibilità di variare la misura al display in vari tipi di 20" non c'è la misura appropriata. Su asfalto liscio si sentono i denti dei copertoni, non tanto con le orecchie ma con i polsi sul manubrio, abbastanza accentuati. In conclusione, prezzo elevato ma rapportato all'eccellenza del pneumatico che niente a che spartire con i copertoni (termini diversi perché prodotti diversi) provati finora, BST, Kenda etc. Decisamente è più sicuro quanto a tenuta e di spessore elevato per le varie spine raccolte finora. A fine estate aggiornerò la recensione riguardo alla durata AGGIORNAMENTO al 28 sett. 2025: Dopo 6000 km ho invertito anteriore e posteriore, il posteriore aveva un consumo di 2 mm rispetto all'anteriore. Confermo la buona qualità dei copertoni che si comportano egregiamente in ogni situazione, ho fatto salite e discese del 20% su sterrato e sentiero con un ottimo grip e tenuta. Su asfalto liscissimo, non hanno perso la vibrazione provocata dai tasselli, ma trovo che sia l'unica pecca e trascurabile. Ottima resistenza alle forature, anche se consiglio del lattice nelle camere per precauzione, infatti girando le gomme ho trovato una spina (6000 km!!!) nel posteriore ma vulcanizzata dal lattice della Wag.
