The Value Question
The simple answer: For most bike types, buying used offers better value because you avoid year-one depreciation (25-35% value loss).
But it depends on:
- Bike type
- Your experience level
- Risk tolerance
- Specific circumstances
Let's break it down with real UK numbers.
Depreciation: The Key Factor
How Bikes Lose Value
| Age | % of New Price |
|---|---|
| 0 (new) | 100% |
| 1 year | 65-75% |
| 2 years | 55-65% |
| 3 years | 45-55% |
| 4 years | 35-45% |
| 5+ years | 25-35% |
Year one is brutal: A £2,000 bike loses £500-700 driving it off the forecourt.
New vs Used: 3-Year Ownership
Example: £2,000 Road Bike
Buying New:
- Purchase: £2,000
- Resale after 3 years: £900
- Net cost: £1,100
Buying 2 Years Old (£1,100):
- Purchase: £1,100
- Resale after 3 years: £650
- Net cost: £450
Saving from buying used: £650 (59%)
This is why used bikes offer better value for those who can assess them.
When to Buy New
1. E-Bikes
Why new makes sense:
- Battery health is critical (and hard to verify)
- Warranty protects expensive motor/battery
- Technology improves rapidly
- Reputable seller ensures quality
Exception: Dealer-certified used e-bikes with documented battery health
2. Your First Bike
Why new makes sense:
- Warranty protection (mechanical issues covered)
- Dealer support (free adjustments, advice)
- Peace of mind (no hidden problems)
- Correct sizing (fitted properly)
Better approach: Buy entry-level new, upgrade used later when you know more
3. Very Cheap Bikes
Why new makes sense:
- Used cheap bikes often have problems
- Repair costs may exceed value
- Quality used bikes cost similar to cheap new
- Decathlon/Halfords entry bikes are reasonable value
The rule: Below £300 used, quality is very variable
4. Latest Technology
Why new makes sense:
- Electronic shifting (new generations improve)
- Specific new features you want
- Marginal gains matter to you
5. Specific Configuration
Why new makes sense:
- Exact size, colour, spec you want
- Custom builds
- No compromise on requirements
When to Buy Used
1. Road Bikes
Why used makes sense:
- High depreciation, reliable technology
- Quality brands last well
- Easy to assess condition
- Huge used market
Sweet spot: 2-3 year old bikes with 105 or Ultegra groupset
→ Browse used road bikes at /bikes/road
2. Mountain Bikes
Why used makes sense:
- High depreciation
- Tough and long-lasting
- Trail demo bikes often available
- Previous year models heavily discounted
Watch out for: Crash damage, worn suspension
3. Hybrid/Commuter Bikes
Why used makes sense:
- Simple, reliable technology
- Low maintenance needs
- Huge used supply
- Great value under £500
Sweet spot: £250-400 for quality 2-3 year old hybrid
→ Browse used hybrids at /bikes/hybrid
4. High-End Anything
Why used makes sense:
- Depreciation hits expensive bikes hard
- Premium components are durable
- Marginal difference from new
- Significant savings
Example: £5,000 new bike at £2,500-3,000 after 2 years - same performance

Frequently asked questions
Is buying a used bike worth it?
Yes, for most bike types. Used bikes save 25-35% on total ownership cost because you avoid year-one depreciation (biggest value loss). Exceptions: e-bikes (battery health critical), first bikes (warranty peace of mind), and very cheap bikes (quality concerns).
How much cheaper are used bikes?
Typically 35-50% cheaper than new for 2-3 year old bikes in good condition. A £2,000 new bike costs £1,000-1,300 at 2-3 years old. This saving increases for higher-priced bikes.
What should I check when buying a used bike?
Essential checks: (1) Frame number against stolen databases (cyclesite.co.uk/bike-history/check), (2) Frame for cracks/crash damage, (3) Drivetrain wear (chain stretch, cassette teeth), (4) Brake function, (5) Wheel true, (6) Test ride everything. Get proof of purchase.
Should I buy a new or used first bike?
For complete beginners, a new entry-level bike (£400-800) offers warranty protection, dealer support, and correct sizing. Once you know what you want, buying used for your second bike offers better value.
Is it safe to buy a used e-bike?
Riskier than other categories because battery health is critical and hard to verify. Only buy used e-bikes with documented battery health (cycle count, diagnostic report) or from dealers offering certification. A degraded battery can cost £400-700 to replace.
