FAQ
Questions before you ride.
Is the D3S road-legal in Europe?
Yes. Pedal assist is limited to 25 km/h in line with the European EPAC rules for electric bikes.
What real-world range should I expect?
The rated range is 35 to 60 km. It depends on assist mode, terrain, carried weight, tyre pressure and temperature.
Does the bike fold easily?
Yes. The compact frame and stem fold in seconds, so you can store the D3S under a desk or carry it in a boot.
What rider height is it designed for?
The D3S suits riders roughly 147 cm to 178 cm tall, thanks to its adjustable seat and stem.
What is the maximum supported load?
The D3S supports a total load of 120 kg (about 265 lb), including rider and luggage.
How long does the battery take to charge?
Allow about 5 hours for a full 0–100% charge with the supplied charger.
Can it ride in the rain?
IP54 protection resists splashes and light rain. Avoid immersion and high-pressure washing.
Does the bike arrive assembled?
The D3S arrives almost ride-ready: just unfold it, adjust the seat and top up the tyres if needed. A manual is included.
