What are the 20 × 4-inch fat tyres on the FF500 actually good for?

The wide tyres create a larger contact patch and a more planted feel on loose, uneven or poor-quality surfaces. Combined with the front suspension, they make the FF500 more forgiving than a narrow-tyre city bike.The trade-offs are extra weight and rolling resistance. Fat tyres are useful for comfort and stability, but they do not make the bike a substitute for a purpose-built mountain bike on technical trails.

Can the FF500 battery be removed for charging?

Yes. DYU lists a removable 48V 14Ah battery, so it can be charged away from the bike. This is particularly useful because the complete FF500 is heavy and inconvenient to move just to reach a socket.

What range should I realistically expect from the FF500?

DYU advertises up to around 70km from the 48V 14Ah battery under favourable conditions. A 31kg bike on 4-inch fat tyres can use considerably more energy when ridden hard, uphill or on soft ground.For real trip planning, leave a generous reserve and expect rider weight, tyre pressure, temperature, terrain and assistance level to make a noticeable difference.

Is the DYU FF500 opvouwbare elektrische fatbike easy to assemble?

The DYU FF500 opvouwbare elektrische fatbike arrives mostly assembled. Final setup normally includes aligning and securing the handlebars, fitting the pedals and completing essential safety checks. Allow approximately 20–30 minutes, or select our professional assembly and PDI service.

Is the DYU FF500 opvouwbare elektrische fatbike water resistant?

The DYU FF500 opvouwbare elektrische fatbike is not fully waterproof. Avoid prolonged exposure to heavy rain, and never submerge or pressure wash the bike or its electrical components. After riding in wet conditions, wipe the bike dry and store it in a dry, sheltered location.
