low smoke without carbon deposits. works fine for 2 stroke dirt bikes.

Mine has been up and running for a week now and I can confirm that it is achieving BETTER than advertised speeds with NO tweaking or mods of any kind. It is VERY quiet and I HIGHLY recommend it.

Perfect for adding a derailleur to a single speed frame, used it on a single speed Mongoose Fat Bike no troubles.

Ed is a great guy to work with.  He answered his text from me within a minute.  I bought one for my VTX 1800 and the other for my Triumph Speedmaster.  This light is BRIGHT!  It is awesome!!  It uses almost no power.  I had "Super Bright Halogens" before in both the headlight and spots (H3's).  Couldn't use the spots with the headlight as it would use too much power.  Now with all the lights on, my voltage is at 14.25.  Before it went down to 12.0 which is of course not enough.  The fan motor at the opposite end of the light adds maybe a half inch or so of depth to the light assembly.  After I removed the headlight lens cover I noticed a lot of wiring.  I moved the wiring looms from directly behind the rear and lifted and easily moved one set of wires to go above the light and the other two to both the left and right of the light within the headlight housing.  This allowed for plenty of room for the additional depth of the H4 light.  The fan motor is whisper quiet and there is no way you can hear it with the bike running.  You can barely hear it with the engine off and ignition in the on position.

Works well so far. A bit pricey at more than $30. Unfortunately, 8 speed freewheels are not easy to find.

Perfect dirt pedal.  Being able to fine tune the mids is the best feature.  Compact and easily fit on my board.

I'm trying to get back into mountain biking and looked at several MTB's. I particularly like the 8-gear setup on the Hook as it is simple and less maintenance. I took it off-road and 8 gears are enough.
I followed the recommendation of another reviewer and installed a different front gear sprocket. The chain stays on but I hear a grinding noise from the chain touching the plastic chain guard.
The components seem fine, I have had no issues with any of he standard components so far.
I also like the value I got for the money. Much better than any off the cheap chain store bikes but not too expensive either.
I am 6'3" and the XL frame is perfect for me. Assembly took me about 1 hour but I also replaced the factory front gear with an upgrade which added additional time.

Installed on an 80 gallon emglo with a 5 hp single phase motor and it works perfectly.
I have already burned 2 of the cheaper ones up already.

i bought this scooter with the intent to make it go really fast.
 stock at 5500 foot elevation with me at 160 lbs on it it would go about 25 mph not 35 .. maybe going down a hill or something
- i put a gp460 46cc engine on it with 4.2hp stock instead of the little 2hp thing it had on it. its 260 bucks
- then i installed a jetpro rhino tuned exhaust pipe from jetpro .. that made a huge difference added a powerband. its 180 bucks
-then i put on a different head gasket to raise the compression.. while i had the engine apart i did a mild port job. $10 + dremel
-then i put on a 44 tooth sprocket to get more max speed. $15
-i changed the tires to wet tread pocketbike 9.5 in. tires $30
-i also put clutch saver springs in it so the clutch fully engaged just off idle $10
-and of course a few tuning tricks to get max power from the walboro carb on the gp460 with a race filter and velocity stack.
- i want to try one of those nitrous kits for like 50 bucks but haven't cause i didn't want to hurt my baby. never tried boost bottle.
  im for sure pushing i would guess 7+ hp now and i got pulled over in a 40mph zone and the cop said i was going 46mph but i think it might go faster than that according to my gps ive hit 52mph on it but thats a guess too really..

  keep everything loctite tight cause this thing basically ejects bolts and nuts i feel like every time i ride it i have to tighten stuff or ill lose it..
  one more thing if you live in colorado you have to register it and get a low power scooter sticker which essentially means its a motorized bike .. you need insurance for the sticker .. the sticker is about 6 bucks for 3 years and my insurance is 33 bucks a year..  you have a max speed of 40 also in colorado and you have to put a horn on it or a bell .. and to ride at night you need a light on the front and a reflector on the back.. also in colorado you cant ride on the sidewalk just bikelanes and street..
  overall i love my scooter for the money but i would have went with a genuine goped if money was no object.. the only thing i worry won't hold up to the 7+hp is the transmission it gets oil from the exhaust and chain in the second gear clutch and i have to spray it off with carb cleaner once in a while or itll slip.. probably not a problem with the stock motor.. i only rode it for about an hour with the stock motor but it was fairly quick and started right up with it..

 the belts on the tranny were way way to tight when i got mine and the back tire wouldnt turn at all i thought there was something wrong with it .. but opened the tranny up loosened it and voila.. this scooter goes by the name evox2 made by evo powerboards.. if you look for info online thats how i found it in forums etc.  any 78mm centrifigul clutch motor should bolt up .. like the tanaka 47r or the bluebird 57 but my gp460 is a really revvy beast .. i love it

I purchased this in November 2014 for my five-year-old son. It has performed very well. It has a 250W motor, 7ah  batteries, a on/off half throttle, no suspension,  strong all metal frame.  If you take good care of the batteries they will last many years, always recharge them after use, do not leave them on the charger indefinitely.  Never let lead acid batteries sit around low on charge, they will start to be damaged after only a few days if they are left low.  The size of this dirt bike is best suited for children 9 years old or younger in my opinion.  This dirtbike is easy to upgrade, here are the upgrades I have done in January 2017:
 I put on a 500W  Motor controller, a 350W motor, 10ah batteries, variable speed throttle with digital voltage display, LED headlight, LED brake light, a horn, and cup holder.  My son loves his little dirtbike and he is getting ready to turn eight years old.  Lots of parts can be found on eBay and Amazon.  I have added pictures, but remember it does not come with a headlight or any extras that you see in my pics.

I have the all black version.  I am a casual bike rider.  I got this one second hand for about 100 dollars.  It was brand new and still had the wrappings/packaging on it.  I know little about setting up bikes but was able to put the thing together in less than an hour (after I found the right tools).  The bike rides great.  It is a single speed with one front break.  Great for casual riding, commuting, city riding.  Looks great and the build quality on all the components are great.

I'm not a bike snob, if you are this isn't a 5000 dollar bike so don't have all of those high expectations going into this.  If you are someone who wants a well built single speed bike with the ability to make it into a fix gear this is the bike for you!!

The other reviewers sound like they are not running the proper hub spacing and chainline. You cannot just throw a freewheel on a Mountain bike.  This is a low cost throw away freewheel and it seems to be at least equal to the higher priced Shimano.  I run a White too and this freewheel works fine.  I've been running them on my two Beach single speeds for years and they still spin free and quiet.  A bargain at $10.

I would give 5 stars but it doesn't have gain adjustments or separate crossover. Power is good. quality is average. Can run 2 or 4ohm . I would recommend it to others. Running jbl 6.5s in the fairing and 5.25a in the rear. This is on a Harley Davidson ultra classic.

This is the upgraded Motorcraft design to replace the OEM metal-housed DPFE which was known to fail prematurely (though it wasn't the case with mine). Easy 5 minute swap.

I'm working on my second single-speed conversion project and used this crank (in black) on my first one and was very satisfied with it, so I ordered another one (in red) for my current project. Great cranks at a reasonable price! Very nice engraved logo and lettering on them. Never a problem with them. The customer with the creaking should try spreading a thin coat of grease on the spindles before pedal installation and cranking them down tight-----should eliminate this as a source. Could be a seatpost creak too, which could be mistaken for a crank squeak.

I use Mobil 1 v twin  20/50 in my vt1100 shadow spirit I like it. bout after 2000 miles  when I check the oil level it was about 1 quart short with out any oil leak.
