20 Most Recent Huffy Pro Thunder Boys 16-Inch BMX Bike Questions & Answers


does it make the "clicking" noise when coasting, pedaling or both? If it is only when pedaling, check to make sure the cranks are not rubbing on a chain guard or hitting the frame, if not then the chain is probably too tight and it is the gear cog teeth meshing with the tight chain. Loosen the rear axle nuts and slide the rear wheel forward slightly, this should take care of it. If the noise happens while coasting then one of the wheels could be rubbing on the frame intermittently, or the hub bearings could be too tight (also making it difficult for small legs to pedal) and the bearings are crushed and flattening making the "clicking" noise as they are being ground up.

There are 2 standard sizes:

Standard one-piece cranks 1/2" x 20 tpi

Standard 3-piece cranks 9/16" x 20 tpi.

The Right Pedal (gear side) has a normal thread, the Left has a reverse thread.

Please go to my tips and tricks page. There are links to huffy's website for on-line assembly instructions and detailed owners manuals. Good website.

No, they do not - a chain tool has to be used. Also, a 10 speed (2 gears in front, 5 in the rear) would be quite old, so the rear gear cluster (freewheel) will be worn as well as the chain, and also takes a specialized tool to remove. Replacing both on a Huffy will cost more than the bike is worth.

Google "Huffy motorized bike serial number" and see what you can find. That's all anyone else can do.

Just Google "install 7 speed derailleur" and pick the link or video that works best for you. Better yet, if there's a bike co-op in your city go there for in-person help. You can also get great repair guidance at Park Tool's site: Repair Help

Chain length should be determined by the specific bicycle. Just Google "Install bicycle chain". Almost every guide and video will give you a procedure for sizing the chain. Not all yield the same length, but they pretty much all work. In my view the best source, though, is Park Tools.

It most likely will take a 3/8" x 24 thread per inch nut. Any bike shop will stock something to fit, and even a big box store that sells bikes may be able to help, as well as a nieghbor or craigslist advertiser that sells used bikes.

If it came off even once it was not installed initially with enough torque. At this point there is a good chance the threads on the crank are damaged badly enough that the problem will reoccur. If you bought it assembled return it and complain. If you assembled it's your error, and a good idea to go over all other tighteners and adjustments. Loctite is unlikely to cure the problem. A bike shop may have to install a "Helicoil insert" to fix it, or replace the crank arm.

You may not need tires, but just tubes, and they are not specific to a certain brand. You just need to look at the size printed on the tire and get a tire of the same size and a compatible tube. Bike shops, Walmart and other big box stores and hardware stores are all potential sources. A bike co-op or knowledgeable friend can help, or a bike shop can do the installation. It's important to do properly, so if you decide to strike out on your own be sure to consult several online sources before starting.

Not always the same from year to year. Just Google "install chain coaster brake bike". It's easiest if you have a tool to size the chain. If you have a bike co-op or community bike workspace in town they can help.

Huffy Cycling | Answered on May 19, 2019


You already know it's about 20 years old. The exact year is totally unimportant, as the bike has very little monetary value.

Take old battery off first it will tell you on there, as long as it 12volts and the same size then it will do the job.

Huffy Cycling | Answered on Jan 12, 2019


Condition and quality determine value. A Huffy, even if older, has very little value.

The "rear sprocket" would be a freewheel. They are not meant to be serviced, so a new freewheel would be the common solution. If you actually mean the rear hub ball bearings you need to follow proper repair procedures and will need specialized tools If you have a local bike co-op ("bike kitchen") they can provide both tools and assistance. Otherwise Google "overhaul rear hub".

Just loosen the bolts on each side of the clamp under the seat!

Huffy Cycling | Answered on Aug 20, 2018


Not possible to ID by serial number, and even if it was it's not important. Huffy's are not valuable and parts are not specific to a particular brand, let alone year or model of bike. The model name is printed on the bike's frame. If not there bike has been cheaply repainted, possibly because it's stolen.
