How to buy an e-bike: find the right model for city, commute and transport

If you're looking to buy an e-bike, you'll probably start by comparing motor power, range and price. But these figures alone aren't enough. What really matters is whether the electric bike suits your height, your daily route, the terrain you ride on and the load you need to carry. An electric city bike for your commute has different requirements to a cargo e-bike for shopping or commercial transport.

Common pitfalls when buying an e-bike

1. Maximum range is mistaken for real-world performance

Claims like "up to 100 km" are usually achieved under ideal conditions. Rider weight, headwinds, hills, tyre pressure, outside temperature and the assistance level you choose all affect the actual range. An e-bike with a 100 km range can go much further on flat roads than on frequent climbs with a heavy load.

So pay attention to:

  • Battery capacity in Wh, not just a mileage figure
  • Removable batteries for charging indoors
  • Realistic usage based on your body weight and route profile
  • Charging time and availability of a spare battery

2. 250 watts is promoted as the only power figure

A 250-watt e-bike on a standard pedelec doesn't automatically mean a certain hill-climbing ability. Torque in Nm, the sensor system, gearing and total weight also matter. For use on public roads, you should check the applicable regulations. For pedelecs, pedal assistance up to 25 km/h and the permitted motor power are among the relevant factors.

Higher torque can be useful on inclines. But it doesn't replace a suitable gear system or correctly adjusted tyre pressure.

3. Comfort and safety features are only looked at superficially

A step-through e-bike makes getting on and off easier. But that alone doesn't tell you about the riding position, frame stability or the right frame size. Likewise, disc brakes aren't automatically hydraulic. If you often ride in wet conditions, with luggage or on downhill stretches, you should check the exact brake type.

The key parameters to consider before buying

Battery, range and charging options

Watt-hours are calculated from voltage and amp-hours. A battery with 48 V and 10.4 Ah, for example, delivers around 499 Wh. A battery with 36 V and 15.6 Ah gives around 561.6 Wh. These figures allow a more objective comparison than vague range promises.

An e-bike with a removable battery is especially practical if your bike is stored in a courtyard, cellar or bike room without a nearby socket. To prolong battery life, use the original charger, protect the battery from frost and avoid fully discharging it during long-term storage.

Frame, step-through and load capacity

Check the recommended rider height and the maximum total load. This usually includes the rider, luggage and any accessories. A cargo e-bike or load e-bike needs a sturdy frame, suitable racks and a clearly stated load limit for heavy transport.

Wide tyres increase the contact patch but can create more rolling resistance. The Fiido T2, for example, uses 20 × 4.0-inch wide tyres and, according to the product specifications, is designed for a total load of up to 200 kg. Actual use must stay within the manufacturer's limits for the frame, rack and attachments.

Brakes, gears and lighting

An e-bike with hydraulic disc brakes offers a different maintenance and operation concept to a model with mechanical disc brakes. Hydraulic systems transmit brake pressure through fluid; mechanical versions use a cable. Both systems require regular checks of pads, discs and hoses or cables.

An e-bike with a Shimano 7-speed gear system is suitable for varying speeds in city traffic and moderate inclines. You should also check for mudguards, a rack, lighting and road-legal markings.

FAQ about buying an e-bike

What are the running costs of an e-bike?

In addition to electricity consumption, you'll have costs for tyres, brake pads, the chain and regular servicing. The electricity needed per charge depends on the battery capacity and its state of charge. If you commute frequently, you should also check whether a spare battery, charger and wear parts are available.

How long does an e-bike battery last?

The lifespan depends on charge cycles, temperature, storage and usage. Store the battery in a dry, frost-free place, avoid deep discharging it for long periods and use the designated charger. For the specific warranty and guarantee terms, please refer to the product conditions.

Is a step-through e-bike suitable for longer distances?

Yes, provided the frame size, riding position, battery and luggage solution suit the route. For longer commutes, you should also check range reserves, lighting, mudguards, brake type and the ergonomic adjustment of the saddle and handlebars.
