SENQI Fixed Gear Bicycle Solid Tires 700c x 23

Bone rattlers, definitely sluggish. I wouldn't like them on a freewheel, too much rolling resistance, but that's not as much of an issue on a fixed gear and it's nice to have a no maintenance beater that's always flat free and ready to roll.I'll caution that I've got these on an absolute jalopy. The install was so terribly difficult, I will never be able to get them off of the wheelset in one piece, and because all of the road bumps transfer right into the wheel, I have some concerns that I could taco something or pop a spoke and I wouldn't want to damage a nice bike by riding with these things.Still, cheap and useful for the right application.

If you are not athletically inclined, or do not ride regularly, these tires are going to be a challenge. They have a lot of drag and you won't roll far after you stop pedaling. I'm by no means a particularly athletic person but I do ride my bike about 6-7 miles daily to and from school, these tires made the ride extremely difficult. What was a casual ride on air tires became a serious workout on these solid tires. They generally do not go as fast nor provide a very smooth ride when compared to air-filled tires.Keep in mind that some tools will be required to install them, I took them to a bike repair shop and had somebody install them because I didn't have the proper tools. You can not install these by hand or with a plastic tube lever, at least I couldn't and that seems to be the general sentiment regarding them. In the event that the tire comes off the frame while riding you must be prepared with the proper tools or you will not get your tire back on. I had one of them pop off after I slipped into a planter and it nudged the tire off the rim. So while they might not be able to puncture and fail if they pop off you're kind of screwed unless you're well prepared.Lastly, I weight about 250 pounds and I shredded through these after a couple weeks of riding. My rim literally shredded through the rubber and began grinding on the concrete. I replaced them with regular air-filled tubes and have never looked back.Highly unrecommended for casual riders and highly unrecommended in general because regardless of riding difficulty (that was a given when purchased them) the fact that they basically fell apart is pretty indicative of the quality of this specific brand.

this tire is actually a great deal for a bike that is used to run to the store or for a kids bike that lives in an area where flats are constant. it it well made and fits the rim great, but its very hard to put on. you will likely need two people to install it, but, its because its not got a tube and doesn't go flat so the tire has to fill in the tube space too. it rolls with more resistance than a normal tube/tubeless tire because it flexes alot when riding so the tire seems only half "aired" up when you are on the bike... more rubber on the road so more resistance. it would be great on a touring bike in parts of the world where tubes are hard to come by or for someone who just wants to not worry about flats and isn't worried about high speed riding in a group. a buddy and i tried this on his recumbent and after a few days of attempting to ride in the medium speed group, we had to take it off and put a tube tire back on. this will be used on his commuter bike though as it seems way more suited for that type of work. a great idea and great for certain uses though

Look peeps they are not that hard to get on you just need to use a tire iron or other sturdy metal tool like a flathead screw driver and pry it onto the wheel. Don't be afraid to use stretch it over the frame its meant to stretch its made of RUBBER. Also as other people have said use zip ties to or something to tie the sections on as you stretch them onto the frame. I did this and The tire took about 10 mins to put on. Also as for it making it feel like your tires are flat im also gonna say nah man not true. I mean yes it is a solid rubber tire it is not gonna ride like a tubed tire but its not like riding through sand like people make it sound its just that there isnt as much shock absorption in the tires so the ride is a bit more shaky but nothing bothersome to be honest and for me having a tire that is consistent and dependable and will get me where i need to go when i need to go there is the tire for me. Am i gonna enter into a race and use these tires Nope. will i use them all the time YA BABY!

I put these on front and back and was quite happy to not have to ever change a flat again... but there is so much drag that you have to peddle down hill. I went back to pneumatic on the back and gained enough... but took a tight corner and the tire buckled on the road and I was thrown over the bike.Kids bikes and wheelbarrows yes... no otherwise.

Less than 18 months into using these tires, one split open. Prior to that, they are slick with any moisture on the road and rub off with a flat area when braking to a skid.

TLDR;difficult to install; difficult to ride, might as well just ride flat tubes.I bought three pairs of these (different colors) at once with high hopes. I commute to and from work everyday by bicycle I thought the different colors would help with visibility during different seasons. I am currently unable to determine if these are just too soft or if the increased road friction due to the material is what's causing the problem, but it is insanely difficult to peddle and requires way more energy to keep the bike moving. While they are solid and will not go flat, it feels like riding on flat tires... in mud.

Perfect fit! Perfect tire for my husband's favorite bicycle. No more air pumps or inner tubes needed!
