Noisy During Use
Bowflex Fitness Equipment
Severity: MinorWhat Does This Error Mean?
Most Bowflex noise during use comes from loose bolts, a dry treadmill belt, or resistance cables rubbing. Check all bolts with the provided Allen keys — they loosen from vibration over time. Apply treadmill lubricant to the deck if you hear squeaking under the belt.
Affected Models
- Bowflex Treadmill 10
- Bowflex Treadmill 22
- Bowflex Bike C6
- Bowflex Bike VeloCore
- Bowflex Max Trainer M9
Common Causes
- Loose frame or deck bolts from vibration
- Dry treadmill belt squeaking on the deck
- Resistance cables rubbing on the frame
- Pedal or crank arm loose on bike models
- Roller bearing worn on treadmill
How to Fix It
-
Tighten all visible bolts and hex screws.
Use the Allen keys and wrench provided with the machine. Focus on the deck bolts, upright post bolts, and handlebar bolts. Do not overtighten — snug is enough.
-
Lubricate the treadmill deck if you hear squeaking.
Lift the edge of the belt and apply 100% silicone lubricant to the deck. Repeat on the other side. A dry deck squeaks rhythmically with each footfall.
-
Check resistance cables on Max Trainer or bike models.
Inspect the resistance cables running from the handlebars. A cable rubbing on the frame makes a consistent ticking or scraping sound. Reposition it away from any metal edges.
-
On bikes, check the pedal and crank arm connection.
A clicking sound that syncs with pedalling is often a loose pedal. Tighten the left pedal counter-clockwise and the right pedal clockwise with a pedal wrench.
-
Apply a dry lubricant to squeaking pivot points.
For arm handles and pivot joints, use a silicone spray or PTFE dry lubricant. Avoid WD-40 on plastic — it can damage it over time.
When to Call a Professional
A grinding metal-on-metal noise that persists after tightening all bolts usually indicates a failed bearing or damaged roller. Contact Bowflex support for an inspection.
Frequently Asked Questions
Why does my Bowflex treadmill squeak with every step?
Rhythmic squeaking with each footfall on a Bowflex treadmill is almost always a dry deck. Apply 100% silicone treadmill lubricant under the belt on both sides and walk on it for 5 minutes at low speed.
Is it safe to use a Bowflex that makes noise?
A squeaking or clicking noise from loose bolts or a dry belt is safe to use temporarily — but fix it soon. A grinding noise from a metal component should not be ignored and needs inspection before further use.
