When these first arrived I thought the batteries were dead. It was when I opened them up to see what kind of batteries they needed that I discovered the little pieces of paper meant to keep the batteries from going dead during shipping or sitting on a store shelf. Once removed, the lights worked great! They attract a lot of attention when I'm out riding at night and I've been asked about them a lot. I will say the photo in the listing is a bit misleading you have to be going VERY fast for them to look like a blue ring of light on your tire. This is true of all wheel lights though, so just a heads up about that. Also, if you screw them too far down on the valve stem threads you may inadvertently cause your tire to go flat over night as they can put just enough pressure on the stem to slowly leak air. No problem, I pumped the tire back up and didn't screw them on as tight. Since then, they've given me no problems and like I mentioned before, people really notice them. I like them!

No failures or breakage of the 4 pair I bought. They even came with a little Presta-Schrader adapter.

Only problem is, it's illegal to put a blue light on a bike in California.

I'm going to try putting some clear red tape or plastic over the lens to see if I can get purple, which would be both legal and a cool colour!

The lights work great but one stays on so I had to put paper between the batteries and contact during non-use.

Hard to find size tube for training bike. They installed on my wheels with new tires in a flash. 6 months later and 800 miles they are still holding air.

These tubes work. They are fairly inexpensive and they do a good job. The only thing is the stem is quite long, however, it doesnt hurt anything other than it looks too long.

I was able to put sealant in these tubes, making them very puncture resistant. Also, they are very light, which is a great addition.

I think the rims are 44mm. My local bike store doesn't have them in stock and presta value extenders don't do the trick because the diameter is too small for it. It's just best to buy the right inner tube.

Amazon has very competitive prices and these were able to do the job.

READ THIS BEFORE USING.

As others have said here, the weak point in this stand is the clamp connectors that lock the stand in place. The description is misleading in suggesting you can lock this stand in any position, as you can with higher priced stands. The problem is that the plastic connectors just are not up to the task of supporting the weight of an average bike in an UNBALANCED position. You will likely never get them tight enough to support an unbalanced bike without breaking them, however, there is what I believe to be a flaw in the assembly process that might result in a better working stand if you tend to it first.

Here is what you need to look at: BEFORE YOU USE THE STAND, loosen the bolt that holds the main clamp to its tube and remove the clamp. When you do, you will see there is a notch in the end of the aluminum tube, and inside the clamp there is a tab that is supposed to line up with the notch and go into it. I question whether or not this tab and notch are lined up with each other when the stands are boxed up. I don't know if it will work any better if they are, since I had already damaged mine by using the stand, but it seems obvious that is the way it should be. I drilled a hole where the tab used to be in mine and inserted a screw into it so that it would key into the notch, and it greatly improved the stability of the stand.

That being said, this stand will never hold an unbalanced bike without slipping long-term. Higher priced stands use clamps that are metal on metal, or they are geared or keyed to accomplish this. In practice, the rotating clamps on this stand are only good for changing the angle of the clamp to fit the tube you are trying to put it on. You will need to find the balance point of the bike for whatever angle you want it to sit at, and then clamp it down. I doubt you could use this stand to do something like clamp the bike upside-down from the top tube. Just ain't gonna happen.

But most of the time you will have the bike straight to work on it anyway, and for that it seems quite stable. The legs are wide and stable, and under normal use I don't see it falling over.

One other small annoyance: If you are to believe the instructions, it says to leave at least 3 inches of the top tube exposed on either side of the clamp, or it could become unstable. The problem I have found with this is that if you do it that way, it doesn't always leave you enough room to rotate the pedals without hitting the main bar of the stand, a problem solved on other stands by using an angled main bar. So far I have chosen to ignore this rule, without incident, but we'll see how that goes.

I'm giving the stand a 3 out of 5 mostly because the advertising leads you to believe it can do much more than it actually can. I bought it expecting this after reading the reviews, and I think it will do what I want while spending what I was comfortable spending. Make sure you take that into consideration, and consider saving up the extra bucks if you're going to use a stand a lot, or if you need it to do things that defy gravity.

As one of the other reviewers on here mentions, the most important part of the stand (the clamp that holds your bike) attaches to the base via a set of very weak, very flimsy, plastic tabs. Even when at their tightest, the bike is able to rotate freely if not perfectly balanced on the clamp. I made the mistake of over-tightening just a little bit, because it was proving impossible to make adjustments to the bike with it rotating at the slightest touch, and ended up driving the allen head bolt through the tabs, rendering the entire stand (even more) useless. Without the bolt there to keep the tabs together, the clamp that holds your bike to the base of the stand FALLS OFF.

In an attempt to salvage the stand, I went to Lowe's and bought a pair of face clamps, but no matter how hard you clamp the plastic tabs together, the bike STILL rotates. At least now it doesn't fall off the stand.

This is the worst kind of cheap junk. Spend an extra $50 and get a spin doctor. Or flip the bike on its seat and handlebar.

well... the darn thing looks solid. It sets up fast and it will hold a bike without any fear of tipping/falling. It is easy enough to use without a helper....

Unfortunately it fails in 1 important field. The clamp is attached to the metal arm with a bolt inserted into plastic tabs that squeeze it onto the pole. The clamp on my unit came loose immediately. I tried to tighten the bolt with the included allen wrench (by hand)... The bolt slipped through the plastic tabs with very little pressure, and will no longer fit in the larger sized hole left by the damage. The clamp now slips of the pole freely. Lame.

I noticed, however, with the clamp removed and the arm exposed,that there are predrilled holes in the arm. I believe I can drill through the hard plastic clamp (carefully) and firmly secure it with a bolt going through both the clamp and pole. Of course, this sort of modification should be unnecessary, but I have the idea that this piece of crap would be improved with the makeover. Unfortunately, the way the arm is fixed to the stand is with the same sort of plastic tab/bolt contraption that immediately failed on the clamp... so no doubt I will also be drilling holes to hold this tighter as well.

The only reason this piece of crap got 2 stars is because I believe with some slight modification, this will be a great stand. Like I said before it is sturdy/solid, and for the price that is something...i guess.

Honest reviews on RAD Cycle Products Pro Bicycle Adjustable Repair Stand

This stand is very sturdy yet it is light enough to be moved around very easily. The two bikes that I own 1 mountain and 1 hybrid fit nicely. You do have to apply extra pressure to the knob when you want the bike to stay at a certain angle. After a few uses it begins to grip better and it requires less pressure each time. It has a lot of height and therefore makes it a breeze to adjust to a height that is easy to work on no matter what part of the bike needs attention. It folds up and can be stored in a corner or can be hung up in the garage when not in use. This is a much better product than I thought it would be. I could not justify paying $150.00 for a stand that I am only going to use a half dozen times a year. This one certainly fits my budget and my needs.

I'll chose the garbage any day over this!! Today was the first day that I used the Rad Cycle stand and it nearly broke my collar bone!!! I was adjusting the rear brake on my wife's Trek 4900, the bike weighs all of around 26lbs with upgrades, when the clamp let go and the bike came crashing down onto my right shoulder! The retaining hex bolt pulled straight through the plastic!!!!! I am beyond disappointed and could kick myself for not listening to the other reviews.

Due to back pain, I needed at least a 6" rise over my current straight bar, and settled on a Sinz Cruiser Chromo. I quickly found out that the smaller BMX clamp diameter meant I needed a shim, and this one worked perfectly. Since there is about a 1/8" gap between the two halves (both sides when centered), I used strips of thin double-sided tape to position and hold each in place before positioning and clamping in the stem.

Shimano SG-8R36 Universal Hub Kit Nexus (Silver, 36h 8 Speed) Review

Shimano SG-8R36 Universal Hub Kit Nexus
Customer Ratings: 5 stars
Buy Now
I installed this 8 speed Nexus hub on a recumbent bike I built twelve years ago which was originally equiped with a seven speed derailleur gear set. All my riding here in Florida is on flat land with few hills, so eight speeds is plenty. I'm not a "bike" person per se', so I was not aware of how advanced these internal gear systems had become. Initially was going to install on of the old three speed hubs I remember as a kid, but then was directed to the new hubs like this one. The unit appears vey well made and comes with two external gears that connect to you chain. I used the larger of the two. A snap ring holds the gear firmly in place. The instructions leave something to be desired, which is typical of products built out of country it seems, but there is enough data to get you going after a little study. The only real issue I had with the new hub is that it requires re-lacing the wheel with the correct length spokes. In my case, my rear wheel is a 24". After some research I found a "spoke calculator" program on line that provided me with correct length I needed. Figuring spoke length is not as easy as you might think and it's not something you can guess at. All of the math numbers for the hub are clearly stated with the directions. All you need to do is provided the exact specific dia. of your wheel. This is a little tricky and must be exact. There are many places on the internet that will tell you how to do this. As luck would have it, they needed to cut to length and threaded. My local bike shop provided the 36 stainless steel spokes and new nipples for $2.00 each, cut and threaded. Research showed this to be a fair price. Then, after being told the lacing process by a friend who used to work in a bike shop, I managed to lace and true my first wheel. It's not really hard; it just requires knowing what order to install the spokes and a little patience. It took me about two hours, start to finish. I built my own temporary wheel jig to allow me to true the wheel using stuff I had in my shop. No problem there. Also know this hub does not require any off-set or dishing. All spokes are the same length. I was a little worried at first about this, but it came out perfect when installed on the bike.

If you have not ordered your shifter you will not have the correct parts required to shift the gears. There are two options; a twist shifter and a "Rapid Fire" trigger shifter. The trigger shifter is like three times the price of the twist shifter, but it's what I used because that's how the original shifter system worked and I liked it very much. It's up to you you. Both types work well as designed. Anyway, the required cable connectors, come with the shifter, not the Nexus gear hub. Once you are at the point of making the cable connections is where the instructions become a little frustrating. Again, the internet confirmed the frustration with this part of the installation. In short, with the shifter in 4th gear position, there are two small yellow lines at the hub that will line up with each other. Once you have that relationship correct, the bike is ready to ride. The problem, is that they don't really tell you how rotate the gear hub part that the connector fits into. It's under a clockwise tension and trying to rotate it to the required position to install the cable end and set the adjustment length is a b---h. Understand that the hub parts appear to be a plastic type material so it possible to damage those parts if you are not careful. In the end, after a number of hours of four letter words, I finally broke down a machined my own tool that makes this job easy and painless. It basically looks like a small spanner wrench that picks up the small hole in the rotating part of the hub near the cable end.

Once you finished all of the above, you should be ready to ride assuming you have made any other changes needed for this conversion. If your shifter cable is correctly adjusted, shifting is smooth and fast. I did notice for a number of miles that the hub would seem to "skip" a gear every now and then but this is normal until the unit "beds" in. Now, after a hundred miles or so, it shifts like butter. It trouble free, quite and looks great.

Three other things worth noting are; the shifter functions in the opposite manner than the od derailleur shifter did. Where before I would "pull" the top trigger to shift up, the new hub shifts down. Not a big deal, but after many years of shifting with the old system, it takes a few miles to get used to that. Plus, and this is the feature I really love, you can shift to any gear, up or down, with the bike at a dead stop and no spinning of the pedals. I can't tell how may times I would get caught at a light or need to stop short and be in high gear. What a pain.

And lastly, when the hub is in 5th gear, it's direct drive, which means it's most efficient and no wear is being done to the internal gears. As such, I selected a crank gear that allows me to be in 5th gear at my most comfortable cruising speed and proper cadence of about 85 RPM. Just food for thought.

In the end, this project ended up costing a little over $400, which is more than I had counted on, but I turned out exactly like I wanted. Hope this helps for anyone thinking of making this change.

This hub is quiet (no ratcheting) and shifts very cleanly. It's actually kind of spooky how well it works. I've bought 3 so far and am very pleased with the performance.

It's hard to justify a derailler system after using this. Your chain never falls off either and maintenance is almost non-existent.

Smooth shifting and a wide range of gear ratios from low to high. Had my local bike shop build me a new wheel with the hub. switched out the old nexus 3 speed that was pretty useless.
