About this calculator
Bicycles lose value through a combination of time, wear, and market factors. This calculator models depreciation using: value = round(originalPrice × 0.85^ageYears × condition × max(0, 1 − mileage / 50,000) × tierMultiplier). The 0.85^ageYears term applies a 15% annual depreciation rate, compounding each year. The condition factor (0.95 excellent down to 0.45 poor) scales the result linearly — a bike in Very Good condition (0.85) retains 85% of its age-adjusted value. The mileage factor reduces value to zero at 50,000 km, reflecting mechanical wear. Finally, a quality-tier multiplier applies directly: 0.7 for a high-end road/mountain bike, 0.6 for mid-range, 0.5 for entry-level, and 0.4 for a basic/hybrid bike — reflecting that higher-end bikes retain more of their age-adjusted value thanks to stronger used-market demand for quality components.
How to use
Consider a mid-range bike bought for $2,000, now 3 years old, with 8,000 km, in Very Good condition (0.85). Apply: value = round(2000 × 0.85³ × 0.85 × max(0, 1 − 8000/50000) × 0.6). Step by step: 0.85³ = 0.6141; 0.6141 × 0.85 = 0.5220; 1 − 8000/50000 = 0.84; 0.5220 × 0.84 = 0.4385; 0.4385 × 0.6 = 0.2631; 2000 × 0.2631 ≈ $526. Your mid-range bike’s estimated current value is approximately $526.
Frequently asked questions
How much does a bicycle depreciate per year on average?
Most bicycles lose approximately 15–20% of their value per year in the first few years of ownership, which is the rate this calculator uses. Higher-end bikes sometimes depreciate more slowly because there is a strong enthusiast market for quality components. Conversely, entry-level and basic/hybrid bikes can depreciate faster because buyers at that price point often prefer new with a warranty.
What factors affect bicycle resale value the most?
Condition and age are the two most influential factors — a well-maintained five-year-old bike can outsell a neglected two-year-old model. Brand reputation also plays a major role outside this formula; bikes from Specialized, Trek, or Cannondale hold value better than off-brand equivalents. Mileage matters most for drivetrain-heavy components like chains, cassettes, and chainrings, which wear predictably with distance.
Why do high-end bikes hold their value better than basic or entry-level bikes?
High-end bikes tend to retain value better because their frames, groupsets, and components age more gracefully, and there is a strong enthusiast resale market for quality parts. Entry-level and basic/hybrid bikes lose appeal faster as buyers at that price point often prefer new with a warranty over used. This calculator applies a quality-tier multiplier directly — 0.7 for high-end road/mountain bikes down to 0.4 for basic/hybrid bikes — to reflect these real-world resale-market trends.
