Notes

  • The universal freewheel's diameter is 147mm.  Make sure your sprocket/pulley is large enough to clear this.  
  • I am unable to list all my products on the shop app.  This is the only product I have listed so far.  To find more products, including belt kits, please visit beltsNshit.com also, more stock and colors for the universal freewheel adapter

Features

Use Any Sprocket or Pulley

The Universal Freewheel Adapter is designed to fit multiple bolt-hole patterns with near-perfect alignment (within 0.5mm), including:

  • Stock razor sprocket/pulley
  • 76mm pit bike sprocket/pulley
  • Split sprocket/pulley

Prevent Over Threading

Built-in locking tabs prevent the adapter from threading too far onto the hub — a common issue with RSF rims that use un-welded freewheels.  

Already have an over-threaded hub? No problem. This adapter can still be used effectively without relying on the factory locking clip.  As long as the threads aren't toast you're good to go.

 

Shitty Stock Freewheels Suck Shit

Sick and tired of those shitty stock freewheels that can't handle the might of your badass upgrades? It's high time you switched to a robust billet CNC aluminum universal freewheel adapter!

With built in threads there’s no more need to give your wheel the ol’ reach-around to tighten it’s nut while you jerk the Allen from the front. 

 

Regenerative Braking Is Totally Tits

Ditching the stock option for a universal freewheel adapter means more than just durability. It guarantees constant motor engagement, letting you tap into the full power of motor regeneration (braking) with your belt kit. This magic not only feeds energy back into your battery, slightly boosting your range but also goes easy on your brake pads, saving you some cash in the long run.

 

Reliability

Elevate your ride with a universal freewheel adapter and embrace confidence like never before! Leave behind the nagging worries of unexpected freewheel breakdowns. Our universal freewheel adapter doesn't just eliminate the risk of breakage; it also significantly reduces wear on your entire drivetrain. By neutralizing the harsh forces exerted by a freewheel in motion, you're ensuring extended longevity for your motor, chain, mounts, and every other component linked to your drivetrain. Upgrade today for a more dependable and enduring ride experience.

 

Predictability

Want more predictability while stunting? With constant motor engagement, you no longer experience a random delay or an unpredictable surge of power when you twist your throttle. Instead, you receive consistently smooth and predictable power delivery every time.

 

Installation

The 4 notches go facing outwards this way you can remove it with the removal tool later if needed.  There are a few good options to get the freewheel off:

  1. Use the freewheel removal tool with an impact wrench(as shown in this video and this video) possibly an impact driver, or a large hand wrench.  If you use a wrench,  use the axle and the axle nuts to hold the tool down while you crank on it. 
  2. Split it with a grinder like I show in the video above
  3. Go to your local bike shop and have them get it off
  4. Get a new wheel from razor as they are pretty cheap and it's good to have a spare.

These are good cheap impact wrenches:

Broke on me the very first day. Weld was not strong at all.

Hello Nicholas,

I am writing to personally apologize. I just read your review and I am genuinely sorry for the frustrating experience you've had.

I also want to sincerely apologize for the unacceptable delay in my response. I have just become aware of this review platform and it was a serious oversight on my part not to be monitoring it. That is my mistake entirely, and I feel terrible that your feedback went unanswered.

My number one priority right now is to resolve this for you. I left you a voicemail a few moments ago and am eager to connect. Please call me back at your convenience.

I look forward to speaking with you and making this right.

Best regards,
Bryan

Just as described, thank you, can’t wait to install this on my bike

Hell yeah, Summer! I'm just now realizing this review section exists, so sorry for the ridiculously late reply. I was apparently living under a rock. I hope the install went awesome and you've been ripping around on that bike for the last year. Thanks for the killer review!

Questions?

How do I install it on my bike?

Check out the installation guide

Regen?

Absolutely. Just be sure to not overheat your motor and weld your freewheel.

SX vs MX?

The MX and SX have the same distance from the motor to the rear wheel so the belt length is the same.

What about all the other Razor models?

With a bit of work you can put a belt kit on the following razors:

  • MX350
  • RSF350
  • MX400
  • Pocket Mods
  • Dirt Quad(Probably)

Let me know what model of Razor you want a belt drive kit for by filling out this form.

What about the old chain tensioner?

Try to unscrew it. I didn't have much luck unscrewing mine so i just cut the bitch out.

What about the old freewheel?

Freewheel stays but needs to be fixed/welded. The rear pulley mounts on to the freewheel just like the old sprocke. Highly recommended using a welded freewheel as this reduces wear and tear on your drivetrain drastically.

Should I worry about snapping a belt?

One time I snapped a belt while testing the limits of the belt's tension. Under normal tension the belt should not snap or skip. If you hear skipping you should check the tension on your belt. Be sure to check out our installation guide for proper installation techniques.

Does it squeek in the rain like my car belt?

No. Only v-belts do this. Timing belts don't slip or squeak even when soaking wet.

Mud?

Not so much with the V1 kit. The V2 kit has slots for debris to pass through the pulleys if you do a lot of mud trails.

What is better for off road riding?

For hardcore off road riding where sticks and shits gets in the gears chain may be better. Most hardcore dirt bike riders use chains. Probably for a good reason. I am working on a tool free belt replacement option that may work well for this scenario.

How did beta testing go?

International shipping?

Yes. Please contact us for details. Taxes and duties are a bitch but doable.
