These are a decent improvement to pedals for a casual cyclist who doesn't want to bother with full-on clips. They are fairly easy to install (assuming your pedals have holes pre-drilled in the front). You won't get the grip or power from these as you would with a clip, but still will have some improvement over bare pedals. They do take some getting used to as you have to make sure the pedals are right-side up when you put your feet on them, you can't just mash your foot down. All that said, these are durable and seem to work well for what they are.

They're a little harder to engage than my previous Look pedals, but not bad.  The other 'vintage' Look pedals lasted over 20 years at about 1000 miles per season, and are still functional, and there didn't seem to be a reason to replace them, other than I felt it was time (well, the berrings were getting a bit squeaky.  These new pedals have a lot more play, and I anticipate riding a tricycle before these babies wear out.

It took a minute to figure out how to install them, but once on the bike they work well. This is my first time using foot straps, and I like how wide and comfortable they are. One concern was being able to get them cinched down tight for longer rides on a fixie. But the design makes it very easy to cinch the first foot in with one foot on the ground standing still. Once you start riding and get the other pedal flipped over it's easy to wiggle your foot forward and get a very secure connection to the pedal.

As other reviewers said, you'll need to buy some extra stainless flat and lock washers, but the instal of these foot pegs is pretty easy on most roll bars.

I really don't know what people are talking about who say these are "impossible" to install.  I had no difficulty putting them on my toddler's tricycle so he can comfortably reach the pedals.  Not the highest quality merchandise I've ever seen, but they get the job done.

With just a one inch aluminum corner around 1.5 feet for each side, and a few screws, plus a touch of paint, you can place the pedals at a more comfortable position.  The stand is nice,  but this tweak makes it real.

Haven't given them the hardcore Moab test again yet, but they were easy to install and seem like they might prevent the front coil springs from dumping into the dirt like they did last year on Golden Spike. I have a flexy Fabtech suspension, which let the axles extend further than the springs were interested in going. Hopefully, these babies will keep them tacked in place. The self-tapping bolts went easily into the existing holes in the lower spring perches on the axle, and the clamps snug down on the lowest coil. I had to take the weight off the springs so I could rotate them into a good position for the clamp, but otherwise pretty simple.

If you need to angle your foot and you have a little excess room in the front of your cycling shoe, these are a great solution. My shoes were a little loose, so I could get two stacked up under my insole. They fit perfectly in my size 45 Shimano shoes, without having to trim them. I need about 6 degrees of correction, so I also had to use three cleat wedges. Overall, I like the shoe inserts better because the cleat wedges are more laborious to install, and not very durable (they get deformed when you tighten the cleat screws.) They seem overpriced, but I suppose they have to have the wedge-shaped plastic sheet stock custom made...and since it completely got rid of my knee pain, I'm not complaining.

Upon receiving the product, I notice there aren't any manuals, but no worries the clips are already half assembled for you. You'll just have to do minor adjustments like side to side orientation of the clips. And installation was like any other pedals, so there wasn't a need for a manual.

I've ridden around 2000miles with these pedals and I've encountered some problems, you're to judge if they're major/minor...

The clips I received had written on the top, "Large" and as far as I can recall, there were no option during purchase to pick a size. I'd looked into this because my knees where having pain after rides, which didn't exist before the pedals. And after analyzing my pedal strokes and foot position, I realized I was driving the pedals with the arch of my feet. I've looked up replacement clips for smaller sizes and I deemed it not worthy, so I cut some packaging Styrofoam from my waste bin (Woooo) and duck taped it to the clip. Now my balls of the feet are driving the pedal and I'm no longer locking my knee from a heel-down stroke. I wear a size 41 (US 10) Feiyue shoes for reference. Additionally, the teeth on the pedals are aggressive, my shoes have indentations from wear.

I've also dented the pedal frame (the part around the axle) from a slight bump while flipping the bike for cleaning, so watch out for that.  The reflectors are removable and mine eventually fell out.....while riding so unfortunately, one of four are lost.

Now aside from all the problems, this product has served me well. I recall times before having clips where my foot would slide of the OEM pedals and hurt my shins. Now I can spin 120rpm sprints without fear of fracturing my shins!

In Conclusion, I think these are a fine set of pedals if they had included a size option for the clips.

Without specifying the size, e.g. 1/2" or 9/16" it is not possible to know if these pedals will fit your bike!
Pedals appear okay.

UPDATE:
The product description was updated and now specifies that inserts are included so that both 1/2" and 9/16" pedal sizes are accommodated. I have added 1 star to my original rating - now 4 stars.

Great pedals.  Very easy to install on my beach cruiser.  They look great and are very sturdy.  Don't forget to use grease when putting these on.  Grease is not included with these, FYI.

I enjoy tinkering with bikes, so when I saw loose ball and a reasonable price I bought 2 sets.
Both my bikes have identical cranks and identical pedals seemed like a natural progression.
After buying a lot of hubs that seem to have a minimal amount of grease in the bearings, my first thought was to add more grease.
Not necessary! These were amply greased. I thought the bearings were adjusted a bit snug, so I adjusted them. They probably would have  "worn in" OK, But I don't like a gritty feel. IF they "wear in" more, I'll simply snug them up later.
They are a bit heavy and the pegs DO draw "shin blood" if you aren't careful.

Good quality, low cost replacement pedals - all metal design. They do need a little bit of extra grease and some glue on the dust caps.

Have been using a pair of these for the last few months on my cruiser style bicycle and have been very happy with them. They're easy to install with a bit of patience, already have another set on hand for the next change.

I installed these on my Honda CTX700 and really like that they can be installed to be rigid and unmovable or left loose.  On my bike I have the right side installed fixed (rigid) and the left side is installed to be movable.  This allows me to push my floorboard aside for easier access to my center stand.  Installing these and a set of Kuryakyn floorboards is really easy.

Got these for swapping out my cleated pedals when i want a more casual ride. They don't have a super aggressive tread, which is fine. I'm not the guy to calculate my bike in ounces, so the weight doesn't bother me. They are sturdy, don't flex under my weight, and installed easily. Nice cheap cruising around town pedals.

Pedals work great.  I am using these on a road bike.  The extra bit of cage surrounding the clip doesn't seem to make a whole lot of contact with my current biking shoes, but it really helps a lot when I want to jump on my bike with non-bike shoes.  Although if you plan to do that extensively then you are probably better off with the pedals that have an actual platform on one side.
