Bike Maintenance Checklist: Before, During & After Every Ride (2026)


Most bikes don't break down suddenly — they send signals for weeks. The clicking you've been ignoring? That's your drivetrain spending its savings. The slightly spongy brake lever you've adapted to? That's your stopping distance quietly growing.
This guide is structured around how you actually interact with your bike — before you leave, while you're riding, and when you return — not by component category or workshop manual order. By the time you finish reading, you'll know how to read every signal your bike sends, maintain it efficiently, and know exactly when to DIY versus when to book a workshop.

Squeeze both tires firmly. They should resist with significant force. A tire that yields noticeably under thumb pressure is underinflated. Road tires: 80–120 PSI; mountain/gravel tires: 20–40 PSI; e-bike tires (Amflow PL/PX/PR): typically 25–35 PSI depending on rider weight and terrain.

Squeeze each brake lever individually. It should feel firm well before reaching the handlebar. A lever that travels more than halfway before engaging signals air in hydraulic lines, worn pads, or cable stretch. Neither wheel should spin freely while you squeeze the brake.

Give the chain a visual once-over. It should be lightly coated in lubricant — not dry and dull (needs lube), not black and gunky (needs cleaning). A well-maintained drivetrain shifts cleaner and lasts significantly longer. Visit Amflow Support for detailed drivetrain care guides.

Straddle the bike and run through these in sequence:
• Grip both ends of the handlebar and attempt to twist them independently. Any rotation indicates a loose stem clamp.
• Apply the front brake and push the bike forward. A rocking or clicking sensation at the front indicates a loose headset.
• Check that thru-axles or quick-release levers are fully closed and secure on both wheels.
• For the Amflow PL: verify battery charge is sufficient and the Avinox system powers on correctly via the Avinox Ride app.
• For the Amflow PR: check that the removable battery is fully seated and the lock mechanism is engaged before every ride.
• For the Amflow PX: confirm the Avinox system powers on and IoT connectivity status shows correctly in the Avinox Ride app.

| Sound | When it happens | Likely source | Action |
|---|---|---|---|
| Clicking | Each pedal stroke | Dry chain, loose pedal, worn bottom bracket | Clean and lube chain first; if it persists, check pedal threads and BB |
| Squealing | Braking | Contaminated brake pads or rotor | Clean rotor with isopropyl alcohol; if pads are contaminated, replace them — don't ride on contaminated pads |
| Creaking | Standing climbs or sprints | Seatpost (most common), headset, crank interface | Remove seatpost, apply carbon paste or grease, reinsert at correct torque |
| Grinding | Pedalling, any gear | Severely worn chain/cassette, damaged jockey wheel | Stop riding — metal-on-metal grinding accelerates damage rapidly. Workshop visit required. |
| Knocking / thud | Rough terrain, repeated | Loose bottle cage, mudguard bolt, or saddle rail | Push/pull components one by one to locate; tighten the offending bolt |
| Tick on climbs only | High torque pedalling | Chainring bolts, crank bolt | Check chainring bolts (M5, 4–6Nm) with appropriate hex key |
| Motor whine (e-bike) | Engagement / acceleration | Normal Avinox M1/M2S/M2 system operation | Normal. If accompanied by OLED error codes, contact Amflow support. |

• Brakes feel soft or progressive: Hydraulic systems signal air in the fluid line. Mechanical systems signal cable stretch or pad wear. A hydraulic bleed or barrel adjuster turn is needed.
• Gears hesitate, skip, or refuse to shift: Start with the barrel adjuster (half-turn increments). If the chain skips under load, the chain or cassette is likely worn past its limit.
• Front end feels vague or loose: Hold the front brake and rock the bike fore-aft. Any play indicates headset bearing wear. Check stem bolts and fork crown race before your next ride.
• Pedalling feels rough or notchy: Bottom bracket bearings may be contaminated or worn. More common after riding in wet or muddy conditions.

The drivetrain is the highest-friction, highest-wear system on your bike. Clean it first, while everything else is dry, so contamination doesn't spread.
Cleaning sequence: Chain tool → rear cassette (toothbrush in each sprocket gap) → chainrings → jockey wheels → chain again. Use a proper degreaser, not dish soap — dish soap degrades rubber seals in bearings over time.
The WD-40 question: Don't use it on your drivetrain. WD-40 is a water displacer and light solvent, not a lubricant. It evaporates quickly, leaving a residue that attracts dirt and provides almost no load-bearing lubrication. Use dedicated chain lube: dry wax lube in dry conditions, wet lube in wet or muddy conditions.
Chain replacement timing: Use a chain wear indicator. Replace at 0.5% wear to protect the cassette. By 0.75% you're accelerating cassette wear; by 1.0% the cassette is likely already damaged. For all Amflow models (PL, PX, and PR), Amflow recommends replacing the chain every ~1,000km.

Brake pads: Most pads have a wear indicator groove. If the groove has disappeared, replace them. New pads are typically 3–4mm thick; replace at 1mm or less. All three Amflow models are equipped with Magura hydraulic brakes — the PL uses MAGURA MT5 or MT7 Pro, while the PX and PR Carbon Pro use the Magura Gustav Pro with 203mm rotors. Use only manufacturer-compatible pads for each system.
Rotors: Inspect for scoring, warping, and thickness. Rotors below minimum thickness (stamped on the rotor body) should be replaced. Never touch rotors with bare hands — skin oils contaminate brake surfaces and cause squealing.
Hydraulic fluid: Replace once a year regardless of pad condition. Dark or murky fluid indicates moisture absorption, which reduces boiling point and brake feel. See Amflow's service guide for annual brake fluid change recommendations for your model.

Use a torque wrench on all bolts contacting carbon fibre — overtightening is the number one cause of carbon component failure.
| Component | Bolt size | Typical torque |
|---|---|---|
| Stem clamp (handlebar) | M5 | 4–6 Nm |
| Stem to steerer | M5 | 5–7 Nm |
| Seatpost clamp | M5–M6 | 4–8 Nm |
| Saddle rail clamp | M8 | 8–12 Nm |
| Chainring bolts | M5 | 4–6 Nm |
| Brake caliper mount | M6 | 6–8 Nm |

Before you call the service complete, validate your work with a short controlled test ride. This is not optional — it's how you catch the reassembly errors that happen even to experienced mechanics.
What to test: Brake engagement (both independently, hard stop from 15mph); gear shifting through all gears under moderate load; any new noises that weren't present before your service; headset play replicated while riding slowly.
If something feels worse after your service: Stop. The most common culprits are an incorrectly routed cable creating friction, a brake caliper that needs re-centering after pad replacement, or a bolt that wasn't fully tightened. Run through your work methodically before riding further.

| Part | Replacement interval | Notes |
|---|---|---|
| Chain | ~1,000km | Use chain checker; replace at 0.5% wear |
| Cassette | Every 2–3 chains | Replace sooner if skipping under load |
| Brake pads | When <1mm thick | Check monthly; replace sooner if contaminated |
| Chainring | Every 3–5 chains | Look for "shark fin" tooth profile |
| Brake fluid (hydraulic) | Annually | Regardless of how brakes feel |
| Gear cables & housing | Annually | Or when shifting doesn't respond to barrel adjuster |
| Suspension fork service | Every 100h or annually | For Amflow PL/PX/PR: FOX recommends every 150h |
| Rear shock service | Every 100h or annually | Air chamber + damper service |
| Tires | When tread is gone | Replace sooner if sidewall is cracked or bulging |

DIY Confidently:
• Chain cleaning and lubrication
• Tire pressure and tubeless sealant top-up
• Brake pad replacement
• Cable barrel adjuster tuning
• Bolt torque checks (with torque wrench)
• Cleaning frame, drivetrain, and cockpit
• Replacing bar tape, grips, saddles
• Battery charging and Avinox app updates
• Amflow PX/PR geometry adjustments (head tube angle, BB height, chainstay length)
• Amflow PR battery removal, charging, and reinstallation
| Problem | Most likely cause | Quick fix | Time | Go to shop if… |
|---|---|---|---|---|
| Squeaky chain | Dry or dirty lubrication | Clean and apply fresh lube; run through gears to distribute | 5 min | Noise persists after lubing — chain may be worn |
| Soft brakes | Air in hydraulic lines; pad wear | Check pad thickness; adjust barrel adjuster (mechanical) | 2–5 min | Hydraulic lever goes to bar; needs professional bleed |
| Gear skipping under load | Stretched cable or worn chain/cassette | Barrel adjuster (half turns); check chain wear | 3 min | Chain/cassette at wear limit; drivetrain replacement needed |
| Puncture (tubeless) | Thorn, glass, or rim impact | Spin tire to seal with sealant; insert inner tube if unresolved | 2–10 min | Sidewall tear larger than 5mm; sealant won't hold |
| Creaking seatpost | Lack of grease or carbon paste | Remove, clean, apply grease (alloy) or carbon paste (carbon), reinsert at correct torque | 10 min | Noise persists — seatpost may be cracked |
| Chain drops (front) | Worn chainring or narrow-wide needed | Check chainring teeth for "shark fin" wear profile | 5 min | Regular dropping despite good chainring — rear derailleur tension issue |
| Avinox won't power on (e-bike) | Battery depleted or app connection issue | Charge battery; force-close and reopen Avinox Ride app; re-pair via Bluetooth | 5 min | Error code on OLED display — contact Amflow support |
| PR battery won't seat or lock (Amflow PR) | Debris in slide-rail or lock mechanism | Clean slide-rail with dry cloth; re-align battery and push firmly until lock clicks | 2–5 min | Lock mechanism damaged or battery won't power on after reseating |

The original Amflow PL remains the benchmark for lightweight full-power eMTBs. At 19.2kg (Carbon Pro 600Wh, M frame), it's one of the lightest full-power eMTBs on the market — while the Avinox M1 motor delivers 105Nm of torque and peaks at 1,000W. The 2-inch OLED touchscreen, OTA firmware updates via the Avinox Ride app, and 80% battery capacity retention after 500 charge cycles make it the easiest bike in its class to maintain and monitor.
Key specs:
• Peak torque: 105Nm
• Starting weight: 19.2kg (Carbon Pro 600Wh, M frame)
• Max battery: 800Wh
• Max range (Eco mode): 157km
• Warranty: 5 years on carbon frame (first owner); 2 years on Avinox e-system

The Amflow PX arrives with the next-generation Avinox M2S motor — delivering 150Nm of torque and 1,500W peak power, a 45.9% increase in power density over the M1. Despite the power increase, the M2S unit weighs just 2.59kg and operates at under 45dBA, keeping the ride immersive and the motor effectively silent. The carbon frame weighs approximately 2.4kg, with the complete bike starting at 20.6kg.
Where the PX stands apart mechanically is its 40-combination adjustable geometry: 5-position head tube angle (64.2° default, adjustable ±1°), 2-position bottom bracket height (345/349mm), and 4-position chainstay length (438–451mm). This means a single bike can be reconfigured for climbing efficiency or high-speed descending stability using only a hex key — no specialist tools required. The 700Wh custom battery supports 3x fast charging and a maximum range of 144km in Eco mode.

The Amflow PR is built around a fundamental shift in how e-bike range works: its 800Wh battery is fully removable via a slide-and-lock mechanism. You can charge the battery independently without bringing the bike indoors, swap a depleted battery for a charged spare mid-ride, and replace the battery at end-of-life without a workshop visit. The 800Wh capacity with 3x fast charging supports a maximum range of 158km in Eco mode — and with a second RS600 battery (available separately for XL and XXL frames), range extends further still.
The PR Carbon Pro uses the Avinox M2S motor (150Nm, 1,500W peak), while the PR Carbon uses the M2 unit. The same 40-combination adjustable geometry system as the PX is present — with the PR's default head tube angle at 64.5° and chainstay length range of 440–452mm, suited to slightly longer travel and more technical terrain. The carbon frame weighs approximately 2.9kg, with the complete bike in the 22kg class.
