Huffy Green Machine Bike Reviews

My seven-year-old son received a Green Machine for Christmas, and I'm here to share my honest review of it.

The Green Machine Big Wheel

The original Green Machine was a toy of the late 1970s and was a souped-up version of the classic "Big Wheel" tricycle. The Green Machine was fast, had swivel-action rear wheels, and could spin and out-maneuver a standard Big Wheel. The bike was originally targeted to kids who were in the 8–10-year-old age range, and many 30–40-year-old adults remember the bike with nostalgia.

Huffy is still manufacturing the bike, and it is a really cool ride-on toy for older kids. The "stick shift" steering mechanism includes two lever-style handles that control the swivel of the rear wheels. A hand brake is attached to one lever, allowing the child to slow the bike down. A junior version of the bike is also available for kids in the 5–8-year-old range.

The Jr. version of the bike does not have a metal frame, hand brake, or a pneumatic front tire. The frame and wheels are plastic, but the bike functions well and is a great "starter" version of the toy for younger kids. These bikes are not intended for preschoolers, and children under the age of 5 years will not be able to reach the pedals on the bikes (even on the "junior" version).

Green Machine Performance and Review

My 7-year-old son received a Green Machine for Christmas. He is tall for his age, and this bike was preferred over the Green Machine Jr., since he would likely outgrow the Jr. version of the bike in a short period of time.

The bike comes unassembled and is a bit tedious to put together. All of the necessary tools are supplied, including an Allen wrench. The assembly took approximately 1 hour, including the application of the decals.

My son is 49" tall and could barely reach the pedals with the seat pushed all the way forward. The seat is adjustable and will slide back as he grows. He donned his helmet and took the bike out for a spin (literally).

The steering is done via two hand levers, and my son got the hang of it after a few rides. By pulling the levers in opposite directions, the bike is able to spin in 180° arcs. A helmet is absolutely necessary, as the bike may tip over when a spin is performed at high speeds.

The metal frame and front rubber tire make this bike excellent for riding on asphalt and other rough surfaces. Unlike the Razor 360, this bike will perform on our rough country roads. We had considered other spin bikes, but they feature caster wheels that only work on smooth surfaces.

Original Green Machine Pros and Cons


  • The bike fits older children and adults up to 180 pounds.
  • The bike spins and offers a smooth ride.
  • The bike works on rough asphalt as well as smooth cement.
  • The bike is durable with a solid feel.


  • The bike may tip over when spinning at high speeds (helmets required)!
  • Customers have reported problems with the seat breaking or sliding. Our bike did not have this problem, so the defect may have been corrected.

The Green Machine Jr. Performance and Review

The original Green Machine is designed for older children, and will be too large for kids in the early elementary school age range. My younger son is 5 years old, 38 pounds, and 42" tall. Huffy manufactures a "Jr." version of the bike for children in the 5–8-year-old age range.

I assembled the Jr. Green Machine in approximately 90 minutes. This bike was more challenging to assemble than the original version. Sliding the axle pole through the rear tire assembly was extremely frustrating, and this was the most difficult part of putting the bike together. The instructions were also difficult to follow. Once the bike was together, it felt solid and stable.

This version of the bike is all plastic; the front wheel is also plastic, unlike the rubber tire offered in the "big" version. While this bike is the "Jr." size, it is still a large bike and my 5-year-old child could not quite reach the pedals, even with the seat pushed all the way forward. We used a rolled-up towel in the seat to allow him to ride the bike.

This bike performs well and is perfect for younger kids who still want the thrill of a Green Machine. My 5-year-old loves riding his bike and will do spins and other tricks while riding. A helmet is absolutely required for these bikes, as the bikes may tip when spinning.

The Green Machine Jr. is perfect for kids in the 5–8-year-old age range.

Green Machine Jr. Pros and Cons


  • Perfect for kids in the 5–8-year-old age range.
  • Durable and sturdy once assembled.
  • Spins and performs tricks like the "big" version of the bike.
  • Works on rough asphalt as well as smooth cement.


  • Difficult to assemble, particularly the rear wheel assembly.
  • Some customers have noted problems with the rear wheels breaking. We have not had this problem - the difficult and unclear assembly process probably contribute to this problem.
  • The bike may be too large for some small 5-year-old children.

My boys still love their Green Machines, Kristen! My younger son can still ride his "Junior" Green Machine, though he prefers the big one. My older son is 9 1/2 and rides his all the time!

Kristen Howe from Northeast Ohio on April 28, 2015:

Great bike review Leah for kids. Talk about nostalgic, when I remember Big Wheels in the mid 1980s. Voted up for interesting!

Leah Lefler (author) from Western New York on January 04, 2015:

It is a fun bike, RealtorRachael. Our boys love spinning out in the driveway.

Leah Lefler (author) from Western New York on January 04, 2015:

We had an extremely difficult time putting our Green Machines together. I hope you can either return your bike or exchange it for one that is easier to put together. Our boys do love them, but the assembly process was a nightmare!

Rachael Okerstrom from Fort Myers FL on December 26, 2014:

This looks like an awesome bike for kids. Great option for Christmas. Love it!

WowoP on December 25, 2014:

I'm trying to put a big one together for this Christmas (2014). I think I'll have to take it back when stores open tomorrow. The receiving nut for the bolt that holds the wheels on is so full of welded metal that the bolt won't even fit without stripping.

Leah Lefler (author) from Western New York on March 07, 2014:

Oh, Brittany - so frustrating! I had read about issues with the seat cracking and breaking, but hadn't heard about the bolt issue with the frame! Our Green Machine has held up well, but it sounds like there is a definite design or manufacturing problem with the front wheel fork. I hope Huffy will replace the bike or reimburse you for your expenses. I am so frustrated when a toy turns out to be poor quality.. or even worse, has a safety issue. Keep me updated on what happens? I will add your experience into the article (with your permission). Thanks!

Brittany on March 01, 2014:

I am not impressed by this new version of the Green Machine. We purchased on for our son for Christmas this year and had to take one back due to the bolt that holds the wheels to the frame busting after 2 days of riding it and now 2 months later we have the same issue. I'm very frustrated. Just waiting for a phone call from Huffy to see what they will do about this situation.

Leah Lefler (author) from Western New York on December 26, 2013:

Allen, are you trying to put the Green Machine Jr. together? It is EXTREMELY hard to get the limiter pin put through the holes - I was beyond frustrated with the process. I finally got mine through, but I was ready to throw the whole thing across the room by the time I managed to get it secured. The "big" Green Machine is MUCH easier to put together.. the Green Machine Jr. is a pain in the neck! I hope you manage to get the pin through - it is the most difficult part of the entire process. It does help if you have a second person to hold the rear axle steady while you're putting the pin through, but it is nearly impossible to get the entire assembly to line up.

Allen on December 26, 2013:

How did you get that "Limiter Pin" through the plastic and posts for the rear axle? No matter what I do, it won't line up!!! Please help. Thanks

Leah Lefler (author) from Western New York on February 05, 2013:

The Green Machines spin at a pretty high velocity, teaches, so helmets are definitely necessary! My boys automatically put them on when we go outside to ride any sort of bike or scooter. I have a friend whose daughter recently fell from a scooter and had a severe concussion with some bleeding on her brain. She may have permanent brain damage now (slurring words, some confusion) - we hope she recovers, but I am fanatical about wearing helmets. You can fix a broken arm, but you can't fix a broken brain!

Dianna Mendez on February 04, 2013:

I remember how my kid used to love his big wheels when he was little. They are such fun! I am glad you mentioned they need helmets, it can be a little thrilling when you take a spin or tumble. Great share and thanks for the tip down memory lane.

Leah Lefler (author) from Western New York on February 02, 2013:

I remember a Green Machine on our street as a kid, Lipnancy - but it was owned by an older boy. I was born in 1977, so I was still a very little kid in the late '70's and early '80's. These bikes are quite large and really meant for the 8-10 year old age range. I'm glad they came out with the Jr. version, as my younger son loves to ride it, but could never reach the pedals on the full-size version!

Nancy Yager from Hamburg, New York on February 02, 2013:

I do not remember these. I think all we had were big wheels. I find the stirring mechanism interesting.

Leah Lefler (author) from Western New York on February 02, 2013:

Thanks, Mhatter99. My kids really love their bikes. There are some reports of the seat breaking from other customers, so hopefully our Green Machine will be OK (I hope Huffy has fixed the problem). So far, so good!

Thank you for this review.
