Assembly Information
Assembly Video
Watch the assembly guide below before first setup.
Yes. DYU's current T1 specification includes a Shimano 7-speed transmission. That is useful even with electric assistance because you can select an easier mechanical gear for hills and a taller gear for faster flat riding.
This is worth knowing because some older reseller specification tables incorrectly describe the T1 as a single-speed bike.
No. Folding makes the T1 much easier to store or put in a car, but at roughly 22.5kg it is still a full e-bike. It is better for occasional lifting than repeated carrying up several flights of stairs.
Yes. Its 20-inch wheels, 36V 10Ah battery, torque sensor and 7-speed gearing give it a more bicycle-like feel than the smallest DYU folders. DYU quotes up to around 60km of assisted range under favourable conditions.
If your priority is natural-feeling pedal assistance rather than simply having the smallest folded bike, the T1 is one of the strongest options in this DYU group.
The Vélo Électrique Pliable Dyu T1 20 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.
The Vélo Électrique Pliable Dyu T1 20 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.
