Heavy Duty 20x4.0 Fat E-Bike Tire, High-Performance 20X4/102-406 Compatible with 20 x 4.0 Electric Bike, MTB, Mountain, All-Terrain Directional Tread Bicycle Tire

Great tires, perfect for off or on road riding

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.

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....:)

good

I've been using these tires for a few months now as I got them to replace the tires my e-bike originally came with and they are working out a thousand times better.

Look and feel great. Quick delivery

Paid this much for tires they should be at least drivable. I took theses riess ro a professional bike shop to have them put on my son's ebike. The back one was put on first which is labor intensive, then when he went ro put on the front and spun it on the machine there was a defect and wobbled. Since they come as a set, and the back was already put on, now if he takes the back off so I can return them, it will cost me more money to have it done all over again once I return this set. It is not a good situation.

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.

Pneus solides

So far so good, fits perfect, easy to install, fast delivery, smooth ride, low noise. The only thing I noticed is on the side of the tire they say 20 PSI but my last tire I do 30 PSI, so I did the same, I put 30 PSI into these tires, the only thing I changed is the inner tubes, I put the puncture resistance tubes that I got on Amazon, I dont see why i cant put 30 PSI into these tires, so I did and Ive been on a few rides going over some pretty big jumps and curbs through trails and they feel good. Yeah they come all rolled and look like they wouldn't fit but they are perfect. I personally was looking for tires that didnt have seems in them, but only time will tell. The price is pretty good for these so far. I will update.

Tyres are great, slight niggle with the order but all was rectified nice and quick👌🏼 please bare in mind that if your coming from slick road tyres then these being a chunky tyre will most definitely deplete the battery range quicker but apart from that all good.

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.

耐摩耗性は純正と比べものにならないほど高いです！
