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

No installation instructions included with the delivery. Had to YouTube and finally got the tire installed. Tip is to “warm up” the tire so it is more pliable. Still, performance even on an indoor trainer added a great deal of resistance - this could be used as an off-season trainer for a serious cyclist. However, for the average rider looking for the best solution for a durable alternative I’d recommend a tubeless wheelset or a hardshell traditional tire - you’ll enjoy riding much more than with this senqi

This Tires are the option tu avoid punctures ( and I have a lot), during bike rides,on commute and family rides should be no issue, good option, and recommended.but for long rides, and little bit more in to training, This tires are heavy, high rolling resistance, and slow you down ( in my case at half speed) on my usual ride of 12 miles/ 16 mph speed, 46 min Ride, took me 90 min, and 2 rest point to reach the same distance, and a lot more tired.No worries about punctures, but some small rocks remain stuck and I have to stop to remove the rock, and because is a solid tire the hole remains, material didn't return to the previous form.
