The Cheapest E-Bike Per Kilometre of Real Range

The cheapest e-bike per kilometre of real range is rarely the cheapest on the price tag. We divide price by our estimated range, not the claimed one. That changes the ranking. A 399 USD folding bike with 28 km estimated range costs about 14 USD per km. A 1299 USD folding bike with 53 km estimated range costs about 25 USD per km. The cheapest bike is not the best value.

Why Claimed Range Misleads

Manufacturers quote range from ideal conditions. Our catalogue shows a median claimed range of 97 km. Our median estimated range is 47 km. That is a median overclaim of 50 percent. The widest overclaim is 84 percent. 483 bikes out of 505 claim more than our estimate. Only 22 bikes claim less or equal.

The claimed range is not a lie. It is a laboratory number. Real riding includes hills, stops, wind and your pedalling effort. Our formula accounts for those. We use assist consumption of 7 to 20 Wh per km, depending on assist level. We multiply by terrain, tyre, temperature and pace factors. The result is a range band, not a single number.

The Real Range of a 720 Wh Battery

The median battery in our catalogue is 720 Wh. Our worked examples show what that battery delivers under three riding styles. Easy riding gives 94 km, with a band of 82 to 105 km. Ordinary riding gives 48 km, band 42 to 53 km. Hard riding gives 20 km, band 18 to 23 km.

Cold weather cuts range. The same 720 Wh battery in the cold gives 40 km, instead of 48 km in mild conditions. Knobby tyres reduce it to 42 km. Road tyres increase it to 52 km. These differences matter when you compare bikes.

The range band is plus or minus 12 percent. That is our published uncertainty. Use the low end for planning, the high end for optimism.

Price per Real Kilometre: The Method

To find the cheapest per kilometre, divide the price by the estimated range. For example, the Fiido D3 Pro costs 399 USD and has an estimated range of 28 km. That is about 14 USD per km. The Heybike Ranger S costs 1299 USD and has an estimated range of 53 km. That is about 25 USD per km. The Fiido is cheaper per km, even though it has a smaller range.

But price per km is only one lens. A bike with a tiny range may not cover your commute. A bike with a huge range may be heavy and expensive. You need to balance cost per km with usability.

The Cheapest per km: Examples from the Catalogue

We looked at the cheapest bike in each type. The cheapest folding bike is the Fiido D3 Pro at 399 USD, with 28 km range. The cheapest city bike is the VIVI C26UL at 500 USD, with 27 km range. The cheapest MTB is the AAIRSK Q7 at 647 USD, with 21 km range. The cheapest cargo bike is the Fiido M1 Pro at 799 USD, with 41 km range.

Now divide price by range. The Fiido D3 Pro gives about 14 USD per km. The VIVI C26UL gives about 19 USD per km. The AAIRSK Q7 gives about 31 USD per km. The Fiido M1 Pro gives about 19 USD per km. The cheapest per km is the Fiido D3 Pro, but only if 28 km is enough.

Among mid-priced bikes, the picture changes. The Koolux RK10 costs 1068 USD and has 45 km range, about 24 USD per km. The Samebike RS A02 Plus costs 1554 USD and has 47 km range, about 33 USD per km. The G-Force ZM costs 1399 USD and has 55 km range, about 25 USD per km. The Vitilan H5 ALL Terrain costs 1894 USD and has 74 km range, about 26 USD per km.

The table shows that the cheapest per km is not always the cheapest bike. The VIVI C26UL and Fiido M1 Pro offer similar value to the Fiido D3 Pro, but with more range. The AAIRSK Q7 is poor value per km because its range is short for its price.

The Role of Battery Size

Battery size drives range. Our catalogue lists batteries from 187 Wh to 1920 Wh. The smallest battery, on the Onesport OT02 PRO, gives an estimated range of 14 km. The largest, on the Coswheel GT20 PRO, gives 107 km. But larger batteries cost more and weigh more.

Our worked examples show the range for each battery size. A 374 Wh battery gives 25 km. A 504 Wh battery gives 33 km. A 720 Wh battery gives 48 km. A 1040 Wh battery gives 69 km. A 1920 Wh battery gives 127 km. The relationship is not linear because weight and other factors play a role.

Consider the Coswheel GT20 PRO. It has a 1920 Wh battery and costs 2094 USD. Its estimated range is 107 km. That is about 20 USD per km. The Emoko C94 has a 1680 Wh battery, costs 1824 USD, and has 109 km range. That is about 17 USD per km. The Emoko is cheaper per km and has a longer range.

Type Matters: Folding vs MTB vs Cargo

Bike type affects range and price. Folding bikes tend to have smaller batteries and lower prices. MTBs often have larger batteries and higher prices. Cargo bikes are heavy and need big batteries.

The median folding bike has a 720 Wh battery and costs 1299 USD. The median MTB has a 1040 Wh battery and costs 1554 USD. The median cargo bike has a 720 Wh battery and costs 1499 USD. But these medians hide a wide spread.

For folding bikes, the cheapest per km is the Fiido D3 Pro at 14 USD per km. The most expensive folding bike is the ADO AIR Carbon at 4199 USD, with 26 km range, about 162 USD per km. That is poor value unless you need its 15.9 kg weight.

For MTBs, the cheapest per km is the AAIRSK Q7 at 31 USD per km. The Cyrusher Trident Full Suspension costs 5799 USD and has 58 km range, about 100 USD per km. That is the most expensive bike in the catalogue, but not the worst value. The worst value is the ADO AIR 30 PRO at 3335 USD with 27 km range, about 124 USD per km.

For cargo bikes, the Fiido M1 Pro at 799 USD and 41 km range gives about 19 USD per km. The HIMIWAY Big Dog costs 3599 USD and has 46 km range, about 78 USD per km. The Mukkpet Breeze costs 1499 USD and has 46 km range, about 33 USD per km. The Fiido M1 Pro is the clear value leader.

The Overclaim Problem: Real Examples

Some bikes overclaim more than others. The Aventon Ramblas eMTB has the widest gap between claim and estimate. Its claimed range is not in our brief, but its estimated range is 20 km. The Hidoes C5 has the closest claim to estimate, with an estimated range of 27 km.

Overclaim matters because it distorts value. A bike that claims 100 km but delivers 50 km is half as valuable per km as it seems. Our estimate corrects for that.

The median overclaim is 50 percent. That means half of all bikes claim at least double our estimate. When you see a claimed range, divide it by two for a rough reality check. Then use our calculator for a precise estimate.

Beyond Price per km: Cost of Ownership

Price per km is a useful metric, but it ignores running costs. Our cost of ownership calculator totals five years of price, charging, servicing, battery and resale. For a median bike, that total is 1573 EUR. Charging costs 63 EUR, servicing 600 EUR, and resale returns 293 EUR. The cost per km is 0.10 EUR.

Electricity is cheap. Charging a median battery once costs 0.20 EUR. Riding 100 km costs 0.42 EUR in electricity. Riding 5000 km a year costs 21 EUR. Servicing is the bigger cost. Hub motors cost 120 EUR per year, mid-drives 180 EUR per year. A bike with a mid-drive motor, counted from 60 Nm, costs more to maintain.

Battery replacement is a future cost. A 720 Wh pack costs 864 EUR to replace. Over 800 cycles, that pack delivers 38400 km. That is about 0.02 EUR per km for the battery alone. Resale value declines over time. After five years, a median bike retains about 293 EUR of its original value.

Financing and Payback

If you finance your bike, the interest adds to the cost. A 1203 EUR bike over 24 months at 0 percent APR costs 50 EUR per month with no interest. At 9.9 percent APR, the monthly payment is 55 EUR and the interest is 128 EUR. That is a 128 EUR premium for convenience.

Payback depends on how much you ride instead of driving. Riding 50 km a week saves 486 EUR a year. A 1203 EUR bike pays back in 30 months. Riding 100 km a week saves 1072 EUR a year, paying back in 13 months. Riding 200 km a week saves 2245 EUR a year, paying back in 6 months.

The savings come from avoiding car costs. Our formula uses 0.06 EUR per km for maintenance, 0.12 EUR for depreciation, and 0.02 EUR for parking. That totals 0.20 EUR per km. An e-bike costs 0.04 EUR per km for maintenance plus electricity. The gap is large.

What Should You Do Next?

Start with your own range needs. Use the range calculator to estimate how far you need to go on a single charge. Then filter the catalogue by type and price. Look at the estimated range, not the claimed range. Divide the price by the estimated range to compare value.

Consider the total cost of ownership, not just the price tag. Use the savings calculator to see how much you save by riding instead of driving. Use the finance calculator to see monthly payments. Then make a decision based on your budget and riding habits.

The cheapest e-bike per kilometre of real range is the one that fits your life. For short trips, the Fiido D3 Pro is unbeatable. For longer commutes, a mid-priced bike with a 720 Wh battery may be better value. Use the tools on this site to make the numbers work for you.
