Sunlite Thorn Resistant Bicycle Tube, 700 x 35-40 (27 x 1-3/8) 32mm Reviews

Customer Ratings:

Unlike some other reviewers, I've waited several months before posting my review. I don't find it helpful whatsoever to hear someone's opinion about how a functional product looks, or that they haven't tried it yet and can't really offer me any assurances.

Anyway, that aside, before I bought these tubes I made a daily commute of about 15-16 miles every day. I rode over all sorts of terrain, but generally sidewalks and streets, some of which were very scarcely swept and which persistently have broken glass littered all over. Under those conditions I was getting a flat every one or two weeks, and was missing classes in college as a result. Not only was it inconvenient, but it was prohibitively expensive to buy new tubes or have to constantly restock patches and vulcanizing glue.

So I decided to buy a pair of these puncture-resistant tubes. They're not a lot more than regular tubes, really. Installation was a bit finnicky, though; the tubes are very thick rubber and are much heavier than usual. It was difficult to fit them into my tire, but that's probably because my tires were slightly undersized (there's no danger in getting an oversized tube, it's vice versa that you don't want to do). The good thing is that since they're so stiff the danger of pinching them during installation is slim.

I bought a spare just in case I'd have to perform a swap, but, I never even used it! For the past three months I haven't even gotten a single flat. It's practically miraculous. Now I ride over palm trees, debris, glass, and branches and don't even give it any conscious thought. It's certainly saving me a lot of money, and having to remove and patch or swap tires is a royal pain, so I'm glad to have my bike require less maintenance. I had even bought some "STOP Flats 2" tire liners and never ended up needing them. Some people who live in different areas of the continent might want to double up, though, since there are more aggressive species of thorned plants out West, I understand. I live in an urban area in Miami FL and my worst concerns are usually sharp branches and glass.

These also operate and feel surprisingly stiff at low PSI, which I like because it makes bumpy rides more comfortable. The valve stem is disappointingly short, but it's still totally serviceable. All in all, I'm extremely happy with this purchase. The next time I work on a friend's bicycle, I'll be replacing their tubes with these.

-----------------------------------------------

UPDATE: February 2nd, 2013.

I think it's been nearly ten months since my last review. Thus far my tubes are, surprisingly, still going strong. My third tube is still sitting unused in my closet. I've been riding a daily commute of approximately 15 miles, which over the past two months has been reduced to 7 miles, giving me a usage over the past duration of around 2400 miles.

With that said, I've noticed that the tubes are tending to lose their air a little more quickly now, and I have to top them off marginally more frequently. Of course, since the rubber is pretty thick, when the tire drops in PSI it's not imminently noticeable.

Something that's important to note is that these tubes really do weigh quite a bit in comparison to normal tubes. I didn't become acutely aware of it until coming into possession of a second road bike, which I now use to race, while keeping the other cycle loaded with these tubes as a commuter. Since these are basically made for a commuter bike, I don't think this reflects negatively on the product.

I'll probably leave another review in a few months again, or when this tube finally needs replacing.

-----------------------------------------------

UPDATE: August 15th, 2013.

This'll probably be the last time I update this review, at least until I begin using my bicycle again, assuming that the tubes are still good! Don't worry, I haven't given up the ghost; I simply appropriate a new Cinelli cycle that's much, much lighter and faster. I still occasionally use my Schwinn loaded with the Thorn Resistant tires, and I can report that they're still holding air and quite all right after riding around on sidewalks and dirty city streets.

Installed this tube on a Trek 7500 hybrid bike. Much much sturdier tube than OEM equipment. Very pleased.

Keep in mind, stem is only 32mmmight be too short for certain rim applications.

I can not attest to the puncture resistance yet but they sure seems sturdy.

The tube is really heavy though and so thick walled so that it doesn't seem to properly expand inside a Kenda Kourier 700x40 tire I use it with. Furthermore the valve 'stem' is so short so that it may be tricky to pump with some pumps.

I think these are what you want if you bike through mine fields. They are THICK and heavy, leave these at home when you ride the Tour de France. But for cross country or across the hood, these will get you there flat free.

I saw some mixed reviews, but given the price, this works great!

1) Removal of bearings was straight forward.

2) With the two large metal bushings (included) installation was also a snap. Purchase a 1/2" x 5" bolt to compress the bearings with the aid of the bushings. They will go in straight as an arrow.

Save yourself the $100's and do not buy the overpriced compression tools for Park Tools and others. Unless you are full time professional mechanic, this is more than you will ever need.

Review of Bike Peddler Take A Look Cycling Eyeglass Mirror Helmet Adaptor Kit

Customer Ratings:

I purchased this item to allow me to move my Take A Look mirror off my glasses to a more secure mounting point on my helmet. I absolutely love the Take A Look mirror but I have very thin wire frame glasses that just did not provide a secure mount for the mirror. As others have pointed out this is just a simple piece of translucent plastic with two tabs that are supposed to attach to the foam on the inside of your helmet with included adhesive pads. The problem for me with this approach is that I could feel the plastic piece against the side of my forehead and due to the curve of the helmet foam the adhesive would tend to pull away from the foam on one of the tabs. I fixed this by carefully drilling out two very very thin slots in the foam just thick enough to allow a tight fit for the tabs with the adhesive pads removed. Once I was satisfied with the dry fit I removed the tabs from the slots and covered them with some 5 minute epoxy and pushed them back into the slots. The tabs are so thin that once they are epoxied back in the slots the integrity of the foam liner should not be compromised. A very small amount of foam is being removed here and the void in the foam is being filled by the mirror mount. Now my mirror mount is rock solid and sets about 1/4 inch out from the inside edge of the foam. This provides me a very stable rear view even over bumps. I just leave the mirror attached to the mount all the time, but it would be easy to remove and reattach over and over if you are so inclined. Once the mirror is removed you would barely notice the small portion of the plastic mount protuding below the surface of the helmet.

First off, I love the Take A Look mirror. I recommend that product without reservation.

That said, this adapter did not work on my Atmos. The positioning of the straps and support system on that particular lid won't let me mount the adapter in any usable position. But I am not going to base my product score on that. I think helmet designs are diverse enough that it would be nearly impossible to design a simple adapter that worked on all of them.

But about the adapter, it is just a small piece of plastic with mounting adhesive. It is transparent so it won't be an eyesore when the mirror is not mounted. Simple and effective design. Can't say much more about it.

I like the idea of having the option to mount the mirror on my glasses or helmet, and if this product would mount on my hardhat, it would be well worth the price and I would use it and love it. Sorry to report that I cannot use it. I will just continue mounting the excellent mirror on my sunglasses.

I purchased this at the same time I purchased the rectangular eyeglass mirror. I did not know that the mirror could attach to the helmet visor. I attached my old one to my eyeglasses but wanted another option because my sunglasses are thin wire frames and do not hold the mirror well. For what it is it is not bad but I did find that you need to be careful when adjusting the mirror or the helmet as the mirror can slide off the adaptor.

Honest reviews on Bike Peddler Take A Look Cycling Eyeglass Mirror Helmet Adaptor Kit

I actually thought that I was getting the mirror when this adaptor showed up. I sent it back for a full refund to BikeWorldUSA who credited me for my mailing costs. I paid the additional money needed and they sent me the LOOK Mirror.

It was ridiculous to pay almost half the price of the mirror just for $.10 piece of plastic to attach it.

In my 30 years of riding with many different mirrors, I have never purchased a mirror that didn't include all the required attaching hardware. I can easily make the mirror attach with some plastic and double sided peel off posterboard squares.

I did this with my previous mirror that still works fine on another helmet.

I love the mirror itself for the multiple swivel options and it is much sturdier than the plastic mirrors. This is my second Look Mirror. I found that the plastic mirrors with the plastic ball and socket start to loosen after a few years. But the positive side to the plastic mirrors is they are made to easily attach to the helmet.

They should make the Look Mirror with either a helmet attachment end or an eyeglass frame attachment and give the buyer the choice

or just include the plastic attachment. Bike Peddler Take A Look Cycling Eyeglass Mirror.

This plastic bit is supposed to stick inside your helmet and then you can clip the mirror onto it. This worked fine for a while, until I went on a longer ride and really started to sweat. I'm talking about "industrial-strength" sweat! And the adhesive on the adapter, even though it's 3M VHB adhesive, was not up to the task. I love the Bike Peddler Take A Look Cycling Eyeglass Mirror but I ended up using cable ties to attach it to my helmet, after the adapter fell out on that ride.

I'm giving this a "tentative" 5 stars as I purchased it as a Christmas gift for my 2 year old nephew and he hasn't seen/played with it yet. I'll update this review after Christmas with how it went.

Price:

IMHO, the entire recumbent trike market is way overpriced. But in that context, the asking price (although possibly still a smidge high) is about what I'd expect for this type of product.

Quality:

The trike appears to be made from good quality parts (i.e., no parts looked inherently sub-standard to me). The main frame, seat frame, and steering assembly are made of a sturdy metal tubing and the welds look decent. The steering linkage, fenders, fender supports, and crank arms are also made of metal. The pedals and tire rims appear to made of plastic. Once assembled, the trike seems very sturdy with all parts properly fitting together snug and secure.

~The caliper handbrake is adjustable.

~The front tire is inflatable (rear tires are solid).

~The front rim is freewheel (braking with handbrake only or possibly by dragging feet).

~The valve for the inflatable front tire is angled outward and can easily be accessed by a standard bike pump.

~Removable bike flag/post included.

Assembly:

The following parts came pre-assembled: 1) steering linkage/steering arm/complete brake assembly/front frame/forts/front wheel/cranks and 2) seat frame/cushions. So all I needed to do was to attach those two pre-assembled sections to the rear axle and put on the rear tires, reflector, bike flag, decals and put air in the front tire.

~In no rush, it took me about an hour to de-box, read instructions, and assemble the trike (and then another hour or so to apply the custom decals).

~Tools Do yourself a favor and use your own tools to assemble the trike. The manufacture is kind enough to include tools but I found them to mostly cause frustration (with the exception of the allen wrenches).

~Decals The manufacture also provides a nice variety of decals so you can customize the look of the trike. The nice thing about decals is that they are more forgiving if you misapply and need to adjust their positioning. However, if you haven't applied decals in a while (or ever), I would suggest you practice applying (then removing before it dries) one or two of the larger decals you don't plan on using as they can be a little tricky. Also, the instructions indicate to place the decals in water for a few minutes. However, the decals I received took about an hour in warm water before I could properly separate them from their backing.

Portability:

This trike is light enough for just about any adult (even petite moms) to easily lift and it's small enough to fit in the trunk/back seat of a typical compact car.

If I haven't added an update at the top of this review, then this product is still working for me as described.

This thing is absolutely ridiculous. While it is expensive, there is not a better "tricycle" out there for a little guy.

Huge advantages over regular tricycles/big wheels:

StabilityMy son has tipped over other tricycles and become scared to use them. With the low center of gravity this is pretty much impossible to tip even when turning on a hill/driveway.

Free wheelhas a freewheel on the front wheel, in other words you can coast without having the pedals move, very cool and unlike most tricycles/big wheels. Makes it much safer if the kid picks up a little speed going downhill and removes his feet from the pedals(I remember the pedals on my big wheel digging into my shins more than once).

BrakeHas a hand brake, no need to Flintstone it. However the handbrake is too big for my two year old to use yet (can't get his hand around it) so he is still using the flintsone method to stop.

Anyways my 2 1/2 y/o has no problems steering/pedaling this. In fact he can reach speeds faster than I can comfortably walk. Everyone at the park is quite impressed at the speeds he reaches (he luckily is very courteous and respectful not to run people over/pulls to the side of the sidewalk and waits if a dog approaches). He should get a good 2-3 years out of this bike, making a great investment, despite the high price.

Overall

Great bike for the price. Improvements would be increased quality control on batteries and chargers, upgrading handlebar, and redesigning the battery terminals.

Buy it. It works fine for what it is.

Pros

Great value for an electric assist bike. Paid for itself in commuting savings not to mention health benefits.

Comfortable ride (thicker tires help)

Surprisingly quiet motor

Having both Pedal Assist and Twist features is nice

Cons

-Quality control issues combined with 90 day warranty:

-Battery replaced in two weeks (warranty replacement plus shipping charge) $25

-Charger replaced in four months $40

-Battery terminal 1 replaced in five months $20 (part only)

-Battery terminal 2 replaced in 11 months $20 (part only)

-Email customer service never replied to requests. Phone CS are helpful though.

Design Comments

-Basic handlebar design is generally uncomfortable, grips hurt hands without gloves

-Kind of slow with only 7 speeds

-Motor on another bike in the same line is 250 watt, not 450. Could this be marketing voodoo at work? Can't confirm this, though sounds iffy.

-Battery and Bike Weight

The SLA batteries work fine on this bike. These are most cost effective batteries on the market, not most advanced. If you want more of a performance feel to your bike, pony up 400 bucks for the Lithium battery.

Steel that is used in this bike frame is the most cost effective material and also the heaviest. Two other common bike frame materials, Aluminum and Carbon Fiber are much more expensive.

Currie offers the IZip line with improved components at a premium. Via Lento Aluminum frame with SLA battery (extra $200), Via Rapido aluminum frame with Lithium battery (extra $500).

I actually bought this bike from Walmart.com to save on shipping costs. I have had it for 2 months now. I have to say that for the price it is probably the best e-bike you can buy. My first real test for my bike was a sponsored event called 'Bike Around The Buttes'. A forty mile ride with a few hills but mostly flat. I had 2 batteries for this trip. I pedaled at a moderate pace (12-15 mph) in battery assist mode. I was very nervous because I did not think the batteries would last that long. Surprise, the first battery went twenty miles. good thing too because the batteries lasted a whole lot longer than my legs did (I am 65 and about 60 lbs over weight :-). The second battery went about 18 miles. I had forgot to charge it up the night before so it had a short trip to work and back on it. fortunately the first battery had partially come back to life and it brought me the rest of the way to the finish. I was still able to maintain about 12 mph.

The instructions tell you to discharge your battery 2 times completely to 'condition it', but I think this information is incorrect. Please read this article. I just found it today, essential reading IMHO.

The quality of components on my bike are ok for a commuter. The tires are great for street riding, brakes work good, shifting gears is easy, the rims are aluminum alloy and look nice, brakes work great, seat adj. is easy.

I am planning on upgrading the front forks, and the rear derailleur to improve the looks and performance of my bike. I have recently changed out the pedals to sealed bearing units.

Out of the box my bike needed some tuning. the wheels needed truing (I tend to be a perfectionist :-), brakes needed adjusting, and motor chain needed adjusting after the first couple of hours.

If I had it to do all over I would buy it again.

enjoy.

I have owned my eZip Trailz for a year now. I put on about 500 miles on it. I have found that for me an electric bike is the best, environmentally-friendly mode of short range transportation for commuting and pleasure. I have found that many on the market are too expensive and don't come with a free test ride. There are even some upwards of $1,000 that come with SLA batteries.

Pros:

+ affordable entry-level electric bicycle

+ reduction in carbon footprint

+ minimal sweat after a ride; longer distance achieved with same amount of effort as a non-electric bike. (This is the primary reason anyone would get an ebike, right?)

+ convenient battery lock and disconnection

+ free bicycle parking when commuting to work in the downtown zone

+ pedestrians and other bicyclists see you and whisper to each other "hey, that's an electric bike!"

+ torquey 450 watt motor

+ quiet operation

+ brakes and other components are more heavy duty in comparison to a non-electric bike

+ fat road tires are comfortable and has little rolling resisitance

+ 7-speed geared to allow a rider to pedal downhill up to 26 mph (but there is hardly any motor assist past 16 mph)

+ first electric bike; will not be the last. (I will never forget my "OMG!" feeling from the first ride.)

Cons:

bike not meant for trails (despite the name). Stay on roads and sidewalks to ensure the bike doesn't vibrate parts off.

bike is rear-heavy

rear rack support bars started rubbing away plastic battery casing leaving white powdery residue. Eventually lead to loud & annoying rubbing sounds when going over road bumps and cracks.

rear rack bolts loosened themselves off over time. (should've used loctite on them at the beginning)

left side terminal died after 300 miles. Right side died after 200 miles. Comes to find out, the positive wires connecting to the terminal blew off. Required new ring connectors and a little knowledge about cutting and crimping wires.

SLA battery shows weakness after 30-40 charges.

SLA battery drastically loses power after a few miles of riding. Battery didn't have the same amount of oomph as when new. Likely that the range suffers over time as well.(Tough to make it home if your ride ends at the top of a hill.)

After the breakdown at 500 miles, I removed the kit and rode the bike without the motor/battery for 100 miles without a problem. It felt just like a regular mountain bike. This year, I upgraded the bike with a brushless hub motor kit with a LiFEPO4 battery and have been riding for 600 miles now. The bike and all of its components has been holding itself well to the newly found power without a problem.

Its about 3 weeks or so I have been using this bike. Easy to assemble bit heavy as expected for acid base batteries. I use it for my commute to and from Train station.

I ordered this to help me make a 14 mile commute. The bike came well packaged and mostly assembled. Just follow the good instructions and you'll be up and riding in about an hour. (without the battery as it needs 8 hours to charge.)

So far I've put on about 60 miles and here are my impressions:

1. The build quality is good, very strong frame. The rear brakes and derailleur came factory adjusted and I did not need to tweak them. Nice! The front brakes are adjusted during the assembly process, but it's easy.

2. I would recommend putting loctite on the pivot screw threads for the hand brakes. One of mine vibrated off (never to be found) within the first 3 hours of riding. And they are metric, just in case you have to go through the same thing. I also put loctite on the screws that secure the hand brakes to the handle bars as are similar.

3. The battery/motor combination seems well tuned. I set my expectations low and road the bike for awhile without the battery assist. Then on the hill up to our house I used the battery, what a difference it makes, wonderful!

4. Beware of the weight of the bike and battery when you dismount. I'm a bigger guy so it doesn't bother me too much, but you have to take care when you are off the bike if you lift the front tire and the bike is at an angle. The weight of the battery makes the bike want to fall over easier. It's best to grab the seat tube to maintain control when you are moving the bike around.

5. I thought the heavier bike and battery combination would make the bike difficult to move, but the low rolling resistance of the hybrid tires make the bike seem easier to move than my knobby tire mountain bike.

6. The brakes are good and wide to give extra stopping power.

7. I highly recommend the Topeak MTX Trunk Bag DX with Side Panniers. It fastens to the rack solidly and has plenty of room.

8. If you are going to be riding this for more than 30 minutes at a time, I highly recommend getting one of the wide saddle seats with the gel inserts. Unless you are gifted with an iron butt, you'll figure this out soon enough.

Cheers and good riding!

Customer Ratings:

It does what it needs to, however there is one key annoyance that keesp it from being on my wheels anymore.

It requires sealing tape, and even then, if you don't wrap enough it still may leak. If you are using tubulars, it would require removing the tire, and re-wrapping it. Then re-glue the tire. Needless to say I found another extender that has an o-ring that seals much more effectively and can be put on without taking off the tubulars.
