Fiido D3 Pro

Yes. It is a 250W electric bike whose motor stops assisting at 15.5 mph, which makes it an EAPC — legally a bicycle. You need no licence, no tax and no insurance, you can ride it anywhere a normal bike is allowed including cycle paths, and there is no helmet requirement. The rider must be 14 or over.

The manufacturer claims Up to 33 km (about 21 miles). Treat that as a ceiling rather than a figure to plan around: claimed ranges come from the lowest assist level on flat ground with a light rider, and hills, cold weather, tyre pressure and rider weight all take a bite out of it.

About 3.5 hours from empty with the supplied charger.

17.3 kg. That is light enough to carry up a flight of stairs or lift onto a car rack without much thought, which in practice decides how often a bike gets used.

No — this model is locked at the UK assist limit with no setting to change it. In the UK, raising the limit takes the bike outside EAPC rules: it becomes a motor vehicle needing registration, tax, insurance and a helmet, it is no longer allowed on cycle paths, and an insurer will treat it that way after an accident. We record the setting because it decides what a bike can legally be, not to suggest you change it.

No — it uses a cadence sensor, which delivers assistance whenever the pedals are turning rather than scaling to your effort. Simpler and easier going, though less natural-feeling than a torque sensor.

Mechanical disc with power cut-off.
