The 15 essential bike accessories (and which to avoid)

The essentials: don't ride without these

1. Front and rear lights

Mandatory at night and even during the day for visibility. Invest in USB rechargeable branded lights (Lezyne, Knog, Sigma, Giant). Avoid no-name Amazon lights that die in 3 months.

  • Front: minimum 200 lumens to be seen, 400+ to see the road at night
  • Rear: minimum 50 lumens, flashing mode mandatory

Budget: €25-60 for the set (front + rear)

2. Serious lock

A €10 cable lock protects nothing. Invest in a U-lock (Kryptonite, Abus) or folding lock (Abus Bordo). The rule: 10% of your bike's price on the lock.

Folding (Bordo)Medium-high700-1100 g€50-100
ChainHigh1500-3000 g€60-120

3. Helmet

Not mandatory for adults in many countries, but strongly recommended. A good helmet costs €40-80 and should be replaced after any impact or every 5 years.

4. Floor pump (for home)

A real pump with a pressure gauge. Not a pocket gadget. Brands: Lezyne, SKS, Topeak. Budget: €25-50.

5. Mini pump or CO2 cartridge (to carry)

For roadside flats. Mini pump is more reliable, CO2 is faster. Budget: €15-30.

6. Flat repair kit

  • 2 spare inner tubes (right size!)
  • 2-3 tire levers
  • 1 patch kit (as backup)
  • Total budget: €15-25

7. Multi-tool

A compact tool with 2-8 mm Allen keys, screwdriver, and ideally a chain breaker. Brands: Crankbrothers M19, Topeak Alien, Lezyne RAP. Budget: €15-35.

Strongly recommended

8. Chain lube

The chain is the fastest-wearing component. Good lube (Muc-Off, Finish Line, Squirt) applied regularly extends drivetrain life by 50%. Budget: €8-15.

9. Bottle cages + bottles

Hydration changes everything. Two cages + bottles for €15-25.

10. Mudguards

If you ride in rain or winter, mudguards are life-changing. Clip-on mudguards (SKS, Topeak): €15-30.

11. Bike computer / GPS

To track speed, distance, elevation. From basic (Sigma BC, €20) to advanced GPS (Garmin Edge, Wahoo Elemnt, €200-400).

12. Saddle bag

To store your flat kit, multi-tool and keys. Budget: €10-25.

Optional but useful

13. Bell

Legally required in many places. A Knog or Spurcycle bell is discreet and effective. Budget: €10-30.

14. Mirror

Very useful for commuting. Bar-end mirror models (Busch & Muller) are the most practical. Budget: €15-30.

15. Phone mount

For GPS navigation. Quad Lock (the reference) or SP Connect. Budget: €30-60.

What to avoid

  • No-name Amazon lights: short battery life, questionable waterproofing, die fast
  • Cable locks: zero protection, false security
  • Uncertified helmets: demand EN 1078 (Europe) or CPSC (US) certification
  • Poor quality tools: they strip screws and bolts
  • Wrong-size inner tubes: check ETRTO before buying (e.g., 700x25C = 25-622)
