Kootu folding pedals LACK Ball Bearings! (exposing Kootu)
I purchased these Kootu folding pedals from Amazon in August 2021, they were listed as Amazon's Choice for folding pedals. Within two weeks of normal use, they wobbled a lot and were leaking tons of grease. I replaced them in early 2022.
Kootu misadvertises these on Amazon as having ball bearings, not mentioning at all the fact the pedals really roll on a single plastic bushing and on the rubber seal! That's right, the rubber is used as a bushing! No wonder they became super wobbly!
I've since replaced these with a nice set of Wellgo folding pedals. They also run on plastic bushings, but are very stable and durable thanks to each pedal having two bushings instead of one. Also, Wellgo doesn't hide the fact they run on plastic bushings, unlike Kootu's pedal design, which are designed specifically to hide the flaws within.

First one i show is a working one, the second detached one doesn't work.
Ohhh…. What a bummer!, Thanks, I almost ordered them. So, any other folding pedals brand that really good? My place is so small, my leg often bumped the pedals since my narrow hallway is the only place I csn put my bike.
I've seen many medium/low end plastic folding pedals work just fine and are reliable for their price. I've since learned that the main issue with the Kootu pedals is that rubber bearing/seal thing, that's what squeals like crazy.
I could see a spark plug causing P0303 but a vacuum leak P2177 ?
This case was a cracked spark plug, yes there's potential that a vacuum leak is possible in your case. Also check MAF sensor is clean and swap around the coils to see if one is bad, depending on your code.
@@ivanvarela3215 MAF sensor was the problem in our car. I cleaned the sensor with electrical contact cleaner and it is working great now.
@@bobsoft good stuff mate!
I hv the same problem, how did you fix it
Ok so it could be many things. Swap the coilover with the misfire with another to see if the misfire code changes location. Check the air intake is secured properly, check the engine air filter is clean and clean the MAF sensor with a can of MAF cleaner. Next, check the spark plugs. Most likely you'll encounter the issue somewhere along the line.
Old-style bottom brackets (cup, caged balls, spindle, caged balls, cup) have the tendency to warp into the aluminum frames. Before this happens, some cups will crack on the race, this is your best indicator to stop and recommend installing a sealed race bottom bracket. To get these out, use a wood working clamp to hold the bottom bracket tool firm. With splined cups, use a BBT-2 (or equivalent) with 2 ParkTool chain whips so torque can be evenly applied by 2 individuals, again being held with a wood-working clamp.
Cause was a cracked spark plug.
How to fix pls
Sparkplug was cracked. Replace spark plugs.
Also could be vacuum leak. Try spraying all the hoses with brake or carb cleaner, if it's leaking it'll Rev the engine.
Ignition coil?
Close, Sparkplug was cracked. Replace spark plugs.
for those maybe still looking, also could be vacuum leak. Try spraying all the hoses with brake or carb cleaner, if it's leaking it'll Rev the engine.
How did you fix it? Same issue, new fuel pump with filter, new injectors and still nothing
Did you ever fix yours? I'm in the same boat, new pump, maf, plugs, injectors, o2 sensors. I'm pulling my hair out here.
@@chrissmith135was just a cracked spark plug.
Spray brake or carb cleaner around all the hoses and see if it revs due to vacuum leak.
@@ivanvarela3215 thx
@@chrissmith135try swapping around the coilovers with each other to see if the misfire changes.
Regardless of the quality of the pedal, grinding nonferrous metals on a stone wheel can be hazardous to your health! Nonferrous metals such as aluminum and brass load up into the structure of the stone and can cause the stone to actually EXPLODE! I've seen it happen. I've been an aircraft mechanic for over 40 years and that is "structures 101". Sanding belts are for such metals. Stones are for STEEL ONLY!
I’m otw with your school bus Ivan. It will be glorious
My god~!

Dang, I wish I'd seen this before wasting my money on this Kootu junk on Amazon!
I ordered them and they just arrived. After what I saw I doubt I'm fixing them on my bike. Waste of money.
Yup, other comments confirm the worst.
Also have one. Are these pedals not serviceable? I look into them but I can't find any nut or bolt which I can use to open it.
Nope, hence why I had to use a grinder.
Had I known earlier, I would've been warned. Unfortunately, I found out late right when you released this video. There were no negative reviews about this before I purchased online, and in the product description it said it has a sealed bearing. I even asked the seller coz the brand was unheard of. At first, I thought I just had to give it time to break in coz it doesn't spin smoothly unlike the legit sealed bearing ones - that the problem was the Litepro crankset was no good since I purchased this for my folding bike. I also doubted its weight, too, but still I gave it a chance. Time went by that one day I started to find myself constantly tightening these each way whenever I use this daily, city to city. I thought maybe I just had put too much grease upon prepping the threads. It was so bad it came to to its breaking point the left crank suddenly wobbled. Upon checking, it ate the threads of both the crank and itself, ending up stuck on one end. I had it machined and maybe have luck on the rethreading the crank using helicoil. These cheap pedals may seem a bargain for its price, weight, and looks, but hell it destroyed my crank's threads holding on to this lousy thing. Didn't even lasted me a year. This crap costed me a new pair of cranks. Never settled for anything less afterwards, so I skipped trying on other options and my curiosity on the quick release pedals and went straight to MKS FD-7 folding pedals instead. Simply the best choice. Bar none.
Shucks. We live and learn.
no wonder mine started cracking noise after several uses. damn!
Đây là loại pedal vớ vẩn nhất mà tôi đã dùng, mặc dù khi vừa mua và lắp lên xe thì trông chúng có vẻ chắc chắn. Tuy nhiên chỉ sau 2 tháng pedal đã lúc lắc và tòi hết cả dầu mỡ ra. Và trục lại tán chặt nên không thể tháo ra sửa chữa được. Kiểm tra lại thì pedal không hề có vòng bi như quảng cáo. Nói chung là không nên mua!
Yeah, piece of crap! They are advertised as having ball bearings, which is absolutely false. Thanks for sharing with us.
No problem! I realized that unless someone exposed them, they'll just keep getting away with it.
What's the most disappointing product you've ordered online?
