How to choose an electric bicycle: a practical guide.

How to choose an electric bicycle: the practical guide (no marketing)

Buying an e-bike is choosing a "system": frame + motor + battery + brakes. If one of these is too weak for your needs, you'll feel it every day.

1) First you decide on the "real use" (not the dream)

City/commute: urban or trekking.
Multimodal (subway/car): foldable.
Steep trails and climbs: e-MTB.
Children/deliveries/shopping: cargo e-bike.

If you're going to use it for urban commutes and want to avoid bureaucracy, focus on pedelec/EPAC (assistance up to 25 km/h) .

2) Motor: select according to inclines and load.

Mid-mounted engine (recommended for hills and heavy loads)

  • better efficiency and response

  • Excellent for climbing and handling extra weight.

Hub motor (okay for flat city and budget)

  • cheaper and simpler

  • It can lose "power" on long ramps.

Quick rule: if you frequently have uphill climbs or will be carrying heavy loads → consider a mid-mounted motor + more Wh.

3) Battery (Wh): the decision that most defines your autonomy.

Forget about "up to 120 km" without context. Range varies greatly depending on conditions (mode, weight, incline, wind, and temperature).

Practical suggestion:

  • Light city/short commutes: 400–500 Wh

  • For climbs and longer distances: 600 Wh+

  • Load, intensive use: 700 Wh+ (when available)

4) Brakes, tires and frame: where is it worth investing?

Brakes: disc (ideally hydraulic) = more safety in rain and downhill.
Tires: puncture-resistant for city use; wider for comfort and stability.
Frame: easy to put on and take off (especially in urban/cargo situations); the right size prevents pain.

5) Weight and ergonomics: the detail that makes you either love it or regret it.

E-bikes weigh more. If you have stairs, a small elevator, or need to carry them, consider this:

  • Electric folding (more compact)

  • Removable battery (for charging without getting on the bike)

  • frame with handle/friendly shape

6) Final checklist before clicking “buy”

  • Is it a pedelec/EPAC 25 km/h for urban use?

  • Battery with enough Wh for your journey?

  • Quality brakes?

  • Warranty and support in Portugal?

  • Anti-theft devices and accessories (lights/reflectors) — essential items for security.
