Amortization Calculation
When does the e-bike pay for itself?
Compared to the car
Investment e-bike: €1,499
Monthly car costs (fixed): €400
Monthly e-bike costs: €30
Monthly savings: €370
Amortization after: 4 months
You will have recouped your investment in just three months. Everything after that is pure profit.
Compared to public transport
E-bike investment: €1,499
Monthly public transport costs: €49
Monthly e-bike costs: €30
Monthly savings: €19
Amortization after: 79 months (6.5 years)
It takes longer here, but keep in mind: After 5 years, you can still sell the bike for ~€400. Realistic amortization: ~5 years.
Hidden financial benefits
1. Tax advantages (commuting)
If your employer offers a company bike scheme:
Up to 40% savings through salary sacrifice
Example: €1,049 becomes €630 net
New amortization compared to a car: 2 months
2. Healthcare costs
Studies show: Regular cyclists have lower healthcare costs.
Fewer sick days
Lower risk of cardiovascular disease
Better mental health
Hard to quantify, but real. Count on €200-500/year in savings for the healthcare system (in economic terms).
3. Productivity
No traffic jams means:
More punctual for meetings
Less stress
A better start to the day
For freelancers and entrepreneurs: Time is money. 50 hours/year less in traffic can easily be worth €1,000+.
4. Resale value
The Rex Commuter S as an electric brand bike with Shimano and Gates components retains its value better than no-name alternatives.
Estimated values:
After 2 years: ~€650 (62%)
After 4 years: ~€500 (48%)
After 5 years: ~€400 (38%)
A no-name e-bike is often at 20-25% after 5 years.
The question: How much does an e-bike weigh financially?
The question "what does an e-bike weigh" takes on a new dimension here. It is not the physical weight that counts, but the weight in your budget.

The Rex Commuter S is not a bargain at any price. It is a well-thought-out e-bike electric bike with a fair price-performance ratio. The 60% discount on the MSRP is not a marketing gimmick, but reflects genuine, competitive pricing.
For price-conscious commuters who think long-term, it is one of the most rational mobility decisions you can make.
And let's be honest: when was the last time you made an investment that paid for itself after 4 months and saved you €370 every month thereafter?
FAQ
Is an e-bike worth it for short distances (<5 km)?Financially yes, but the health benefits are lower. A conventional bike might make more sense here.
What happens to the battery after 5 years?It can be replaced (approx. €500). However, it often still has 70-80% capacity and remains usable.
Can I deduct the e-bike from my taxes?As a professional commuter, yes (commuter allowance). As an employee, you can save up to 40% via company bike schemes.
Is insurance mandatory?No, but highly recommended. E-bike theft would otherwise be a significant financial loss.
Is the model also available as an e-bike in white?Yes, the Rex Commuter S is available in several colors. The price does not vary by color.
How do rising electricity prices affect costs?Minimally. Even if they doubled to €0.60/kWh, the annual costs would only increase by €15.
All calculations are based on average values. Individual results may vary. Status: 2024.
