E-bike commuting: 44 km a day and the fine print on range

Commuting by e-bike: 44 km a day and range that doesn't add up

Is an electric bike worth it for commuting? The math looks simple: 22 km along a bike path through a forest versus 30 km by highway, half an hour stuck in traffic, and fuel costs of around 8 euros a day. A mid-range e-bike starts at 1,000 euros. A kit to electrify the bike you already own, 300. The problem shows up when you add up the real kilometres, the rain and the battery that ages.

The starting point of the calculation is a 44 km daily commute (22 each way). The law limits the motor to 250 W and assistance to 25 km/h; above that, the bike stops being a bike and falls into moped territory, with type approval, insurance and a licence. Cheap kits promising more power and more estimulante ilegal exist, but they put the user on the wrong side of the law.

Kit or integrated bike: the devil is in the cables

The kit option is cheaper, and that's where the advantages end. Those who have installed one tell it like it is: in the seller's photos everything looks clean; in reality, the cables are zip-tied to the frame and many connectors are left exposed. With frequent rain, that's a problem, not a cosmetic detail.

The integrated bike costs three times as much, but arrives assembled, with a warranty and with components designed to work alongside a motor. Even so, the final tune-up isn't optional: out-of-true wheels, loose bolts and badly adjusted brakes show up on bikes fresh out of the box. A bike shop charges around 50 euros to get it right, and it's worth budgeting for.

How many real kilometres does an e-bike battery deliver?

The 100 km some models advertise is measured under ideal conditions: light load, flat terrain, minimal assistance. In the real world, with an 85 kg rider and heavy assistance, the figure falls far short. For 44 km a day, a just-enough battery means charging at work or pedalling unaided one way.

Wear makes the math worse: a battery that today covers the route with room to spare will lose capacity in two or three years and stop doing so. Buying extra capacity isn't a luxury; it's the difference between using the bike and leaving it parked.

The real cost versus the car

The fuel savings are real: about 8 euros a day in petrol versus cents in electricity. But an honest calculation includes the spare battery, maintenance and time. By bike, the commute takes around an hour and a half a day; by car, an hour with traffic. The difference is paid in health or in hours, depending on how you look at it.

Some argue that, at these prices, an old diesel still works out cheaper. That argument ignores the health cost and the air you breathe on the bike path. It also ignores that the e-bike doesn't replace the family car: it complements it.

---

The conclusion, with the numbers on the table, is uncomfortable: the 1,000-euro e-bike isn't an indulgence, but it isn't the bike the brochure promises either. It's a vehicle with shrinking range, maintenance needs and a battery that expires. Anyone who buys it counting on the advertised 100 km will discover the brochure lies less than it seems: it simply doesn't talk about their commute.
