The True Cost Per Mile of Riding an E-Bike

The true cost per mile of riding an e-bike is about 0.11 EUR per km for a median bike over five years. That figure comes from the purchase price, charging, servicing, and what the bike is worth when you sell it. It is far cheaper than driving, and the savings calculator tells you exactly how much you would save.

Understanding Cost Per Mile

Cost per mile sounds simple: divide what you spend by how far you ride. But an e-bike has costs that happen once, like the purchase, and costs that happen every year, like servicing. Some costs, like battery replacement, happen only after thousands of kilometers. To get a fair number, you need to look at a period long enough to include all of them.

The five-year view is the standard. In five years, a median bike will have needed servicing, some charging, and possibly a battery. It will also have a resale value. The cost of ownership calculator totals all of that for you. For a median bike, the five-year total is 1642 EUR, and the cost per km is 0.11 EUR.

Your own cost per mile depends on three things: how much you ride, what you pay for the bike, and how you maintain it. Riding more spreads the fixed costs over more kilometers, which lowers the cost per km. A cheap bike with a small battery will have a different profile than a premium bike with a large one.

Breaking Down the Costs

The purchase price is the biggest cost, but it is not the only one. Over five years, a median bike costs 1642 EUR in total. That includes 63 EUR for charging, 600 EUR for servicing, and the loss in value from 1399 USD to 316 EUR at the end. The bike itself is not the whole story.

Purchase Price

The catalogue has 275 bikes from 37 brands. The median price is 1399 USD, the cheapest is 399 USD, and the most expensive is 4499 USD. A quarter of bikes cost under 999 USD, half under 1399 USD, and three quarters under 1899 USD. You can spend more, but you do not have to.

The price spread is wide. For example, the Fiido D3 Pro costs 399 USD and has a 374 Wh battery. The Cyrusher Trident costs 4499 USD and has a 1040 Wh battery. The median bike, the Velotric Nomad 1, costs 1399 USD with a 691 Wh battery. What you pay affects your cost per mile, but not as much as you might think.

Battery Replacement

Batteries do not last forever. They are rated for about 800 full charge cycles. On a median 720 Wh battery, that is about 38400 km of ordinary riding. When it is time to replace it, a 720 Wh pack costs about 864 EUR at 1.2 EUR per Wh. That is a significant expense, and it is why the cost of ownership calculator includes it.

Battery size varies a lot. The smallest in the catalogue is 192 Wh on the Ridel Cruzzer, and the largest is 1440 Wh on the Troxus Trax Plus. A smaller battery costs less to replace, but it also gives you less range. The range calculator helps you match battery size to your riding.

Servicing and Maintenance

Maintenance is not just tires and brakes. The motor type matters. A hub motor costs about 100 EUR a year to service, while a mid-drive costs 120 to 180 EUR a year. Most bikes with more than 60 Nm of torque are mid-drives, so check the specification.

Over five years, servicing a median bike comes to 600 EUR. That is more than the cost of charging by a wide margin. The cost of ownership calculator uses these figures, so you can see the difference between motor types.

Charging Costs

Charging is the smallest cost. Electricity to ride 1 km costs 0.00 EUR, and 100 km costs 0.42 EUR at 0.28 EUR per kWh. Riding 1000 km in a year costs about 4 EUR in electricity. Even 5000 km costs only 21 EUR. Charging is almost negligible compared to other costs.

Resale Value

What you get back when you sell matters. After five years, a median bike is worth about 24 percent of its original price. For a 1399 USD bike, that is about 316 EUR. The resale value is based on a formula that accounts for age, and it is included in the cost of ownership calculator.

Total Cost Per Mile

The total cost per mile is the five-year total divided by the kilometers you ride. For a median bike, the cost per km is 0.11 EUR. That is the number to compare with driving. It includes everything: purchase, charging, servicing, battery, and resale.

Your cost per mile depends on how much you ride. If you ride 3000 km a year, the cost per km is lower than if you ride 1000 km a year, because the fixed costs are spread over more distance. The cost of ownership calculator lets you enter your annual kilometers and see your own cost per km.

Comparing to Other Transport

The main reason people want a cost per mile is to compare with driving. Driving a car costs about 0.06 EUR per km in maintenance, 0.12 EUR per km in depreciation, and 0.02 EUR per km in parking. That is before fuel. An e-bike costs a fraction of that.

The savings calculator compares the two. If you ride 50 km a week instead of driving, you save about 486 EUR a year. At that rate, a 1295 EUR bike pays for itself in about 32 months. Ride 100 km a week, and you save 1072 EUR a year, paying back the same bike in 14 months. At 200 km a week, the saving is 2245 EUR a year, and the payback is 7 months.

Even if you already own a car, replacing some car trips with e-bike trips saves money. The savings calculator uses your local fuel and electricity prices, so it gives a figure for your situation.

Ways to Lower Your Cost Per Mile

The biggest lever is riding more. The fixed costs, like purchase and battery, do not change, so more kilometers means a lower cost per km. If you ride 3000 km a year instead of 1000 km, your cost per km drops significantly.

Choosing a cheaper bike also helps, but not as much as you might think. A 700 USD bike like the HITWAY BK15M has a five-year total cost of 1153 EUR at 3000 km a year, which is 0.08 EUR per km. A 3599 USD bike like the HIMIWAY D7 PRO will cost more, but the gap narrows if you ride a lot.

Servicing is another lever. A hub motor costs less to service than a mid-drive. If you are handy, you can do some maintenance yourself, but the figures here assume professional servicing. The cost of ownership calculator lets you compare motor types.

Battery care matters. Avoid extreme temperatures and do not let it sit at zero percent for long. A battery that lasts 800 cycles is cheaper per km than one that dies early. The range calculator also helps you choose a battery that fits your needs without paying for extra capacity you do not use.

• Ride more kilometers to spread fixed costs.
• Choose a bike with a smaller battery if you do not need long range.
• Prefer a hub motor over a mid-drive if you want lower servicing costs.
• Maintain your battery to make it last the full 800 cycles.
• Buy at the right price: use the catalogue to find deals.

Hidden Costs and Savings

Some costs are easy to miss. Battery replacement is the biggest hidden cost. A 720 Wh pack costs 864 EUR, which is more than the resale value of a median bike after five years. If you keep the bike long enough to need a second battery, that cost will appear.

Another hidden cost is financing. If you borrow to buy a bike, the interest adds to the purchase price. A 1295 EUR bike over 24 months at 0 percent APR has a monthly payment of 54 EUR and no interest. At 9.9 percent APR, the monthly payment is 60 EUR, and the total interest is 138 EUR. The finance calculator shows the true cost of credit.

There are also savings that go beyond money. Riding an e-bike produces about 5 g of CO2 per km, compared to 170 g for a car. Over a year, that adds up. A tree absorbs about 22 kg of CO2 per year, so riding instead of driving is like planting trees.

The range of an e-bike is also a hidden factor. The claimed range is often optimistic. The median bike claims 97 km, but the estimated range is 48 km. That is a 50 percent overclaim. The range calculator gives a realistic estimate based on your riding conditions.

Real-World Examples

To see how the numbers work, look at a few bikes from the catalogue. The cost of ownership calculator gives a five-year total and a cost per km for each, assuming 3000 km a year.

The HITWAY BK15M is the cheapest mountain bike at 700 USD. Its five-year cost is 1153 EUR, which is 0.08 EUR per km. The HAOQI Leopard Pro costs 1899 USD and has a 1056 Wh battery, but its five-year cost is 1802 EUR, or 0.12 EUR per km. The more expensive bike costs more per km, but it also has a larger battery and likely better components.

The Velowave Rover and Velotric Summit 1 are other examples. The Velotric Summit 1 has the highest five-year cost at 2362 EUR, which is 0.16 EUR per km. That is still far cheaper than driving, but it shows how price and maintenance add up.

How to Use the Calculators

The MathBikes calculators do the arithmetic for you. The range calculator estimates how far a battery will take you based on assist level, terrain, tires, temperature, pace, and rider weight. The savings calculator compares riding to driving. The cost of ownership calculator totals five years of costs. The battery calculator converts amp hours and volts into watt hours, range, and charge cost. The finance calculator works out monthly payments and total interest.

Start with the cost of ownership calculator to get your cost per mile. Then use the savings calculator to see how much you would save by switching from driving. If you are choosing a bike, use the range calculator to make sure the battery fits your commute.

The true cost per mile of an e-bike is low, but it is not zero. The median bike costs 0.11 EUR per km over five years. That is a fraction of the cost of driving. The best way to know your own number is to use the calculators with your own inputs.
