I had the local bike shop, (LBS) assemble this beauty so that part was stress free. They will do a free cable adjustment in a couple weeks as well, so I would recommend that newbies like me use a good LBS.

I took it out for a casual 40km ride yesterday, my first on a road bike and I absolutely loved it! I got a couple of compliments on how nice the bike looks and the LBS seemed impressed with the components.

Outstanding customer service from Giantnerd! I had a minor shipping issue, being Canadian, and they were quick to help me out.

So far, so good. This has been an awesome purchase.

Review of Xootr Mg with Fender - Black

Xootr Mg with Fender - Black
Customer Ratings: 4.5 stars
Buy Now
I've been a long time Xootr owner. I bought my first over 9 years ago. I have probably owned in excess of 20 of them. I don't keep buying them because they break; I typically donate them to some worthy child I meet on vacation.

Originally I bought a bunch of Razor scooters to take and donate with me while I'd travel to some relatively poor areas of the world. I'd take a few with me and give them to deserving kids I'd meet. At the time I had a Razor scooter myself. It was pretty crappy to ride unless on very smooth pavement and it wasn't really big enough for my large feet to ride comfortably.

One time I returned to where I had previously "donated" a few Razor scooters and met up with the kids I had given them to. Every one of them was broken. I tried to fix them best I could but I had noticed they really didn't last that long in some of these areas.

At this time I searched for a replacement for my "big wheeled" Razor and encountered a little article on the Xootrs. At first I was struck by the thought that would anybody pay THAT much money for a scooter. What were they thinking? I read another good review and another and finally I opened up my wallet and bought a shiny new Street. After 4 days of waiting the UPS truck pulled up with my Xootr.

My first push and then glide seemed to go on forever. I was hooked after that first push. I immediately got rid of all my Razors and I never looked back. The Xootr has been an amazing traveling companion for me. I have Xoot'rd all over the world. I have taken my Xootrs to Russia, Ukraine, Germany, Holland, France, many other countries. Never once I have had to worry about a flat or any other problems while on traveling.

I have now donated quite a few Xootrs over the years. They are more expensive so I don't only donate 1 a trip. I have gone back and seen kids riding the same Xootr 2 or 3 years later. They were a little worse for wear but everything was still working fine with likely no maintenance done to them at all.

Only one recurring issue I see with current Xootrs is that the handlebar alignment pin seems to be off a few degrees so they are not lined up exactly right on any of my scooters. It is a minor thing and doesn't really affect the handling.

I have owned every model of Xootr including the carbon fiber ones they previously made and the eX3 (electric scooter no longer in production and that is a shame!). The magnesium one is a great scooter and a lot of bang for the buck. I love the street as it is incredibly tough. It also has the highest weight capacity if you are on the hefty side like I used to be. The Roma is my favorite. It is narrow (more efficient kick) and the fastest.

Keep in mind that your speed is limited to how fast you can kick. There is no mechanical advantage you get like on a bicycle that has gears. As a result you are going to be limited to going about as fast as you can run but with less effort. I find on level ground I can easily keep up a 10-12mph pace. In the city I am about as fast as on my bicycle but a lot easier to carry with me.

For commutes over 3-4 miles I'd suggest a bike. A Xootr folding bike is a great option too. In heavy traffic the Xootr can allow you to scoot through pedestrians much easier than I can on a bike. It is much more portable.

It is very quick to fold and put away. I also found that while some metro (subway) systems charged me to bring my bike on; they never once charged me for my Xootr. The quick release pin allows you to fold it down in about 5 seconds or less.

If you've read this far I'd like to give a few quick words of advice. Don't ride your Xootr on ice, snow or wet roads. This is a recipe for disaster in short order. The reflective road dividers are slick when dry and absolutely treacherous if even slightly moist. Take time to get use to the braking characteristics. While the brakes work they are not incredibly efficient. You will NOT stop on a dime and get change. They are not efficient at all when damp. Absolutely AVOID puddles. Also watch the bigger holes that could swallow a wheel as well as grates that have long longitudinal gaps. Always try to cross things perpendicularly (right angle). Pretty much the only wear item is the wheels and they are amazing. Bad roads accelerate tire wear.

While riding your Xootr is fun, it can also be fun to customize it too. There are some very neat accessories now. They have carrying bags, handlebar straps and even pretty cool quick-detachable luggage. With the magnesium version you can even get a few different colors. I've added a quick detachable 3 watt LED headlight to mine and a rear light as well. I use a Garmin Nuvi as a nav system on a RAM handlebar mount. I use a luggage carrier up front to carry groceries. All in all it has been one of the best purchases I've made. It is also a great conversation starter when I travel. I feel like I have become a Xootr ambassador when I travel to places around the world. Almost all my friends now have bought them. At first they cringed a bit about the price but after buying them they are incredibly happy and have no regrets. It is the exact opposite of buyer's remorse!

I've been riding a Xootr to work every day for ten years! (since 2000!). I ride to the train, and then I ride from the train to the office. I repeat this on the way home. It's about 3 miles total each day. Over a decade of workdays that adds up to more than seven thousand miles! It's hard to believe but it's true!

My Xootr saves me about one hour of walking per day. Bicycles are not allowed on the train during certain hours, but nobody notices or cares when or where I take my Xootr. If necessary, I can even bring the Xootr into a restaurant or movie theater. Try that with a bicycle! My Xootr adds so much efficiency to my life that I'd pay $1000 or more if I had to. The good news is that I don't have to. They're quite affordable.

Over the years, the company has made a number of meaningful improvements to the design. If you've bought a Xootr in the past, the ones they sell today are the best Xootrs yet!

Just to name a few of the improvements:

The handlebar clamp is now made of solid aluminum whereas it was originally made of plastic (in the early years). The front axle is now a much better design especially if you need to remove the wheel for some reason. The brake itself was much improved when it was moved from the back wheel to the front. The fasteners are larger, stronger and more corrosion-resistant than before, and of course the improved 'ergonomic' locking pin is now standard. There's more to tell, but you get the idea.

In comparison to other scooters:

I've used or researched nearly every push scooter available, and in my informed opinion, nothing else can match the Xootr in terms of offering the right mix of mechanical efficiency, size, style and quality.

I purchased a Xootr Roma (the smallest/lightest model) from the Xootr website for use when I walk to work from the subway. Here are my first impressions:

1. Scooters aren't as easy to ride as I remember when I was a kid. I almost killed myself in my living room trying to balance it without moving. You pick it up very quickly but I would recommend that before you jump into the fire on your first day of commuting with it, you take it out for a test drive or two without the throngs of fellow commuters to fall into. Watch out for curbs you have to be moving VERY fast or jump REALLY high to ollie them.

2. Definitely wear a helmet (I am using my snowboarding helmet in the winter and bike helmet in the summer).

3. It is bigger and heavier than I thought (to carry when collapsed). Even though I had an intellectual idea that it was bigger than a Razor, in my head, it wouldn't be that much bigger. When I opened the box, I was a little shocked.

4. It is VERY well built. This thing feels really solid and the relative high cost compared to Razors is completely understandable once you see/feel it in person.

5. The bag was surprisingly nice and is worth getting.

Overall, I am happy with my purchase and would have purchased it through Amazon had it been for sale here because of Amazon's good customer service (Amazon CS was a known entity and Xootr's wasn't at the time of purchase). That said, it was mailed promptly and I have no complaints about Xootr CS.

(Since Karl Ulrich mentions the fact that they sell their Xootrs on both Amazon and their website, I felt ok using this forum to discuss the Roma. )

Update: One last thing. If you are considering riding one of these any time after a rain, you absolutely have to get it with the rear fender/brake. It is amazing how much water the wheels pick up from what looks like nothing.

Honest reviews on Xootr Mg with Fender - Black

I'd echo much of what others have said. This is by far the best scooter I have ever owned, and I have owned lots. This is probably the 6th Xootr I've bought, also like the other reviewer because I tend to give them away when I see people who really need them.

We keep our Xootr next to the front door. I use it anytime I need to run someplace 1-2 miles away. For these short trips it is better than a bike because (1) it is just easier to grab, and (2) when you get to your destination you can just fold it up and take it with you rather than having to deal with locking it up.

It is perfect for getting to a subway or bus stop, again because you can take it with you. It is also perfect for running to the store because you just step off, walk it around with you in the store, hop back on to go home.

I also use it to take my kids to school when are running late (often). We call it "double-scootering" and my kids love it. Even with my 10-year old on the Xootr with me, it still rides great. School is about 1.5 miles away and hopping on the scooter cuts the trip from 20+ minutes to 7 minutes. And it also gets me back home in half the time, so it saves me about 1/2 an hour round-trip.

I do agree with the other reviewer who didn't like the locking mechanism for the handlebars. It works fine and is reliable and strong, but the pin is a bit awkward and gets a little stuck sometimes. Graphite powder helps. If the Xootr people are listening, this might be the one thing you could work on to make an excellent product even better.

I'd also add that any scooter has a limited range. After about 2 miles a bike makes more senseit is faster and has a smoother ride. I've taken Xootr on some longer trips by necessity and had a bit of a "shaken up" feeling afterwords. But for the short trips it is designed for, Xootr beats bike in terms of both convenience and total time.

In closingthis is one of the few products I own that tangibly makes my life better. If there is 1-2 miles of pavement separating you from someplace you go to regularly, then a Xooter will save you lots of time.

I commute into NYC and use a scooter every day, covering about 3-4 miles. I had a couple years in on regular Razor scooters so did have some experience with various types of smaller wheeled scooters. For the last 2 and a half years I have been riding another brand and I will tell you why.

Here are some of the issues I found with the Xootr I purchased. These were fed back to the team at Xootr 2-3 years ago and got no response.

Handle post is a solid piece.

You cannot detach the bars, so if you need to carry, store or move through crowds of people you will constantly have issues with this. It does not fit in a commuter bus overhear bin for example.

The foot bed is very wide on the standard models.

This has two detrimental side effects: One is again storage, as, not only is it tall folded, but because of the handle post and the width of the foot bed, it also is wide. The second is your kick leg has to move further out and around it to contact the ground. In practice this means that your standing leg has to bend further so that the leg pushing can do it's work. This means that the standing leg gets tired faster.

The magnesium on the foot bed can chip. The magnesium foot bed model is only one of a number of Xootr options, but on the model I had it chipped within the first week, and in a place where there was no contact with anything likely to cause a chip. This looked unsightly and didn't speak highly of the quality of the materials.

The Xootr pin to secure the scooter is a simple idea, in theory, but fiddly in practice. If you drop the pin and happen to be standing over sewer or subway grating or in a crowd of people (Murphy's law says you will always end up in one of these situations for some reason) you are out of luck. The pin also has a bad habit of coming apart very easily (it screws together). If you lose a piece of this pin, you are going nowhere. I tied mine to the scooter with a piece of yellow nylon rope. Why am I tying a $220 product together with string?

The brake is on the front. This is my biggest complaint from a safety perspective and an area where I think Razor actually got it right. I am very athletic and I regularly move through the streets of NYC at speeds of up to 20 mph (depends on the road surface). Drivers and taxis in NY change their minds in a heartbeat and suddenly end up in front of you. You have to be able to stop. With a Xootr you hit the handbrake and you shoot over the front off the foot bed, while holding the handle bars, only to have the foot bed then swing around and whack you in the back of the ankle. This hurts like hell. Also remember you are now standing in the middle of traffic. The Razor scooter design means that to stop you must move your body weight back and over the rear wheel because you use the rear fender to stop. This keeps you solidly on your scooter and still in control. You only need to have a couple close calls to see the flaw in the Xooter design.

Big wheels. You will find that if a scooter is designed with a bit of thought you can have big wheels and easy storage. Razor has just released a large wheel scooter that proves this point but comes up a little short on the foot bed. The larger the wheel the faster and smoother the ride because the rolling resistance is reduced. If you have a long thin foot bed you can rest the front of your pushing foot to the rear of the resting foot without depressing the rear fender. This gives you a very flat storage and the opportunity for bigger wheels.

I ride a "Viza Kickit Air" which came with pneumatic tires which give a very smooth ride, but are silly because they can flat and they actually take so much more energy to push. What is nice about this model, however, is the quality of the build and the fact that you can put 7" wheels on it. I have actually gone from the original wheels to 6" Trikke wheels and then on to Trikke 7" wheels and the ease of ride after the transition to the bigger wheels was noticeable in each case.

So I guess this is as much a review as another design note to Xooter (I simply could not resist when I saw the VP of Xootr and the infamous Dorlene writing reviews). After all, what's the point of continuing to stand still if you are a scooter company ?

The generator was much better than expected. I had a more powerful unit that could not withstand the elements (rain, mud, etc.) but this unit, although less powerful, is rugged.

Click Here For Most Helpful Customer Reviews >>

I bought one of these and set it up on my bicycle back when they carried the BELL brand name, but it's the same unit now that it's sold under the X Factor brand name.

This light is easy to install and set up. Clamp the front bracket to your front forks and adjust so that the bottle dynamo driveshaft is in line with a radius line drawn from the axle. Attach the rear light similarly. Be sure that the ground screw goes into the frame enough that you have a nice circuit or else it won't work. I think a lot of people don't know what the ground screw is for.

String the wire between the generator and the headlamp and the generator and the rear lamp and off you go.

I ride my bicycle for exercise very early in the morning and this system throws plenty of bright white light with the halogen bulb. People can see you better than with reflectors and you can see them. You can also see objects in the road, potholes, cracks, puddles, etc. I really do think it's very, very bright. The rear light gives off a nice bright red glow as bright as the tail light on a car or motorcycle, though it is a lot smaller.

It does turn off when you are not in motion because it is driven by friction from the wheel turning. I have an auxiliary battery-powered rear light for that, but also reflectors keep you visible.

For $20, you really can't go wrong. They do create a bit of noticeable drag depending upon how heavy your bike is, but it's not bad. Since I ride my bike for exercise, the extra drag is good.

Bulbs last a long time if it's wired up well and maintained well (make sure those contacts are clean and bright!). I bought and installed my first one of these back in 2003 and have ridden my bike an hour and a half a day three to four times a week in that time and I haven't had to replace a bulb yet. You can get bulbs on line pretty easily or at reflectalight on the web.

Installing this kit will double the value of your old 1970s era Columbia!

Thought I was getting a good deal with the price. Good price, but the product is lacking in quality. Used it a couple times, then once I got above 20 mph riding the generator wouldn't produce a charge. Overheated very easily. If you gently ride and know how to install it's worth the money, but if you're like me and do a lot of fast riding then it's not worth it. Would have scored higher with a better review if the product was better made.

Honest reviews on X Factor 3-Inch Bicycle Generator Light Set

One issue I had is No Instruction!!! it is very difficult to install this thing.

-This generator is designed to be mounted at the front so the headlight has a shorter wire than the taillight.

In my case, my front fork is too fat so I had to mount it at the back. Then I found out the only way I could

do that is to mount it on the left side (the side without the chain ). It is the only place that you can mount

the dynamo so that when you press the lever it should swing toward the tire to engage the dynamo.

-I also realize that by mounting it at the back, my headlight wire will not reach the dynamo bottle. Also

I would have extra wire length for the tail light; so I had to improvise. Note that each light and the dynamo

has only one positive terminal. The negative terminal is the bike frame so make sure you have good electrical

contact with the bike.

--I figured out how to mount the dynamo but the lights, I had to strap it to the bike using plastic zip ties.

I just don't know how to do it otherwise. I ended up with some screws and bracketts that I had no clue what

to do with them. You may find yourself making a trip to the hardware store to make this work.

-While I tested it worked well enough. The lights are not supper bright but good enough. One thing I like

is the friction wheel (drive wheel) is very quiet. I could hardly hear it or feel it. Note the lights are Not LED.

I opened up and check.

-The drive wheel is plastic but it is hard enough that I don't think it will wear out easily.

-I also tested the voltage with a meter. It can go as high as 9V AC no load, and the current is 0.5 Amps so there

is some extra margin. After you connect the light, the voltage will drop.

Here are some numbers:

The friction wheel diameter is 19 mm which mean if you bike at 15 km / hour or 10 mile / hour, it will turn

at 4200 RPM

The dynamo bottle has two diameters: 4cm and 1.4cm

The total heigh is 8cm and the heigh of the lower part is 3.2cm

fairly small dynamo bottle.

Overall it works fine, if you want a cheap generator. Personaly I would go for the 12V 6W dynamo.

I own an older light set and dynamo (Made in "West Germany") that I pulled off of an old race bike. I got a new bike so I figured let me purchase a new dynamo to compliment it.

My first complaint with this product is that after a certain speed it cuts out. I haven't experienced this with any other generator, but it's extremely inconvenient when you pick up speed as things are getting dark and the light cuts out. To remedy this in I substituted the old dynamo back.

After my second ride, my lights began to flicker after hitting some bumps in the trails (bad connections). Tightened everything up but the plastic bulb holder inside the tail light cracked on me rendering the light useless. So, I substituted the old red light in the back.

As of now I am three days into using the product and 2/3 of the product is already out of commission/not being used. The front light seems to be holding up, but the only problem is when I adjust it it temporarily loses connection and I'll have to tap it to get it running again (happens with bumps too, so I'll have to open him up and see if everything is tight inside).

Overall, I trust the deals in Amazon, they always treated me well. This product though is a perversion of the older dynamo's that used to be sold. At least it shipped to my house quickly :-/.

Perfect inner tubes for my Stella 4T scooter at a great price. These were 3 times more expensive from one of those online scooter shops. It pays to Check Amazon! The tubes are a perfect replacement for the OEM tubes on your Stella 4T, probably better. I paired mine with the Shinko SR550 Whitewall Tire. Ordered 2, tubes, installed them, then decided to order 2 more as spares. If the insides of your split rims are rusting and flaking sand them down and repain't them, that's what caused my puncture in the first place. Will order these again from amazon in the future.

This purchase was a gamble because I really wasn't interested in what I feared would be extra drag and weight just to power a headlight that I might rarely use. But because I go on occasional bike/camping treks, my hope was that I could get the dynamos' output to charge AAA and AA batteries which I could then use to operate a flash light, tent light, reading light, mp3player/radio, etc., in addition to the bike's running lights. The charger I intended to use (UltraLast Green 2AA/AAA/USB On-the-Go Charger with 2 AA Everyday Precharged Batteries) supposedly can also power cell phones through one of its adapters.

After receiving the hub dynamo (ahead of schedule from Bikewagon), I purchased 4 silicon diodes and a USB cable from Radio Shack and built a bridge rectifier to convert the dynamo's AC output to DC required for the battery charger. Because the dynamo output was approximately the same magnitude as the charger input requirements, I was somewhat optimistic for the big test, but guessed it would take at least 3 hours to fully charge 2 completely dead AAA batteries. However, on the test ride I checked the charging progress after 1 hour of pedaling, using a separate battery level indicator, and to my great surprise found the batteries completely charged!

As far as extra weight or drag, I haven't been able to detect any, although I should qualify this by stating that I am a coaster-brake bicycle aficionado and not obsessed with speed. In addition to the dynamo, I believe the Sturmy Archer hub is the only one with a drum brake, which like a coaster brake is protected from the elements. The drum brake has worked out just fine for me as a standalone brake, or in conjunction with the coaster brake to reduce the heat stress of long steep descents. It is comforting to know that the drum brake is always there if the chain derails and the coaster brake becomes useless.

I do have one minor complaint about purchasing the brake lever. The dynamo product description did not state whether the lever was included with the package, although the "frequently bought together" line implied that it was not. I took a chance that it was included and ended up purchasing the lever separately which cost me some time and extra shipping costs. But having a quality alternate brake and being able to generate all the electricity I need for my traveling devices more than compensates, as does the great customer service I received from Sturmey Archer (North America) regarding questions I had about the hub. I greatly recommend this product.

CHARGING UPDATE May 26, 2012: the performance of the above described charging system has declined over the past month. I first noticed that the charger's output function was not working and now, after a few hours of pedaling, dead batteries barely get over half-charged. I am pretty certain there is not a problem with the Dynamo, because the same thing happens when I use the charger's AC adaptor to charge batteries. I certainly can't fault the charger either, because charging it with the variable output characterized by the dynamo is not listed as a feature. Thus the problem could stem from my lack of circuitry knowledge, or even from inadvertently attempting to charge batteries inserted backwards for a short time. At any rate, the initial success showed me what is possible, which will keep me trying (and learning).

I like this hub a lot, particularly for my previous, 10 mile, unlit bike path commute (with Busch & Muller Cyo light also excellent).

Braking: could be better. When new it's pretty bad, but gets better over the next couple of hundred miles. Better than an old single-pivot caliper, not really as good as a modern dual-pivot, let alone cantis, linear pull, disks. Still, quite adequate mostly. Not *entirely* maintenance free eventually get dirty and water does get in there, at which point braking is not as good and they can even stick on. At worst I had them lock on, when very dirty. Cleaning isn't too onerous, and typically once every 3-5k miles. Braking is quite bad the morning after a wet ride home, as some sort of grime has to be dealt with.

Drag: quite apparent when spinning the wheel, not apparent with > 200lb momentum. The bike glides along nicely. It'd be nice if drag was lower, but for the typical
