Cult Crew Juvi Cranks 18″ (2025 Review)

If you’re building out an 18″ setup for a young shredder or just need a shorter crank for your unique build, the Cult Crew Juvi cranks are an absolute gem.

Even if your kid is progressing fast on an 18″ BMX bike and is beating up his cranks, the Juvis are an excellent replacement.

These cranks are just as tough as the full-sized Cult Crew cranks – they’re simply scaled down to 140mm, making them a perfect fit for smaller riders.

Made from heat-treated, swaged tubular chromoly and reinforced with a wraparound spindle and pedal gusset design, these are clearly built for pro-level durability.

Let’s find out more!

Cult Crew Juvi 18″ Cranks Review

1. Features & Build

Let’s run through what makes the Cult Juvi cranks stand out.

Especially if you’re building a serious 18″ setup that needs high-quality components right from the jump.

These aren’t just scaled-down cranks – they’re made with the same top-level mindset that goes into full-size builds.

And when your (little) rider is progressing fast, having that kind of quality under their feet makes a big difference.

• 18″ aftermarket crankset
• 140mm length, perfect for smaller frames and riders
• 3-piece tubular design for easy maintenance and strength
• Heat-treated & swaged chromoly arms for max durability
• Wraparound spindle and pedal gussets add strength where it matters
• 1-piece spindle/sprocket boss design
• 19mm 48-spline hollow chromoly spindle
• Flush-mount hollow spindle bolts
• Compatible with RHD or LHD setups
• Color: Black, Chrome
• Weight: 28.2 oz (799.4 g)

One important note: The Juvi cranks do not include a bottom bracket, so if needed, make sure you grab a 19mm BB separately.

2. Ride Quality & Performance

These cranks feel just like their bigger brother – solid, responsive, and confidence-inspiring.

For any rider on an 18” build, the 140mm length is ideal.

You get smoother pedal strokes and better control, especially when learning new tricks.

The chromoly arms don’t flex or feel sketchy. In fact, they feel a bit more stuff because of having less leverage.

Moreover, the wraparound gussets help add more peace of mind when landing hard.

Also, since they’re RHD/LHD compatible, you can use them regardless of which side you (or your kid) grind on.

This isn’t some watered-down crankset.

The Cult Crew Juvi cranks are full-performance parts made for smaller riders who need epic gear that holds up.

3. Cult Crew Juvi Cranks Price vs Value

At $154.99, the Cult Crew Juvi cranks aren’t the cheapest option.

But when you factor in the build quality, rider-specific design, and lifetime warranty, it’s a smart long-term investment.

Plenty of cheaper options out there won’t survive a full season of aggressive riding.

These will.

Note: Even if you are a grown-up but are shorter and want to try shorter cranks, the Juvi cranks are strong enough.

And yes, they can work on both an 18″ and a 20″ wheeled BMX bike.

4. Real Rider Feedback

• Max T.: “Got these for my kid’s 18” setup. Fit was perfect, and they’ve handled everything from skatepark sessions to trails. Super solid.”
• Luis V.: “Wish more cranks came in smaller lengths like this. The 140mm Juvis feel great and don’t clip my foot on whips.”
• Erica G.: “I’ve run both the regular Crew cranks and the Juvis. Same amazing quality – just a little shorter. Highly recommend for 18s (but tested them and work on a 20″, too).”
• Mason R.: “I was getting pedal strikes with other cranks, but not anymore. These Juvi cranks fixed that and feel smooth.”

Conclusion: Are Cult Crew Juvi Cranks Worth It?

Absolutely.

If you’re looking for a shorter crank arm that delivers full-size performance, the Cult Juvi cranks should be at the top of your list.

They’re strong, clean-looking, and backed by a lifetime warranty.

Whether it’s for a smaller rider, a compact setup, or just a custom build – they bring the performance without compromise.

If you’re all about doing things right from the start, the Cult Crew Juvi cranks are 100% worth the price tag.

These will last a long time.

• Final verdict: Tough, responsive, and sized just right for smaller setups. A proper pro-level upgrade for 18″ BMX bikes.
