FAQ

Q: Are your cargo bikes compliant with EU EN 15194 regulations for electric power-assisted cycles?

A: Yes. Standard commercial configurations feature 250W nominal mid-drive motors, pedal-assist actuation without a throttle (unless specified for non-EU markets), and a maximum cut-off speed of 25 km/h, fully compliant with EN 15194 and EPAC directives.

Q: What is the expected lifespan of the battery packs under commercial fleet operating conditions?

A: The Samsung/LG lithium-ion cells utilized are rated for 800 to 1,000 charge-discharge cycles while maintaining at least 80% of their original nominal capacity. Under typical daily commercial usage (one full cycle per day), this represents approximately 3 to 4 years of operational service.

Q: Can we integrate our existing fleet management telematics or GPS tracking systems?

A: Yes. The electrical architecture includes dedicated CAN bus communication ports and auxiliary 12V power outputs, allowing seamless integration of third-party telematics hardware for real-time location tracking, remote diagnostics, and geofencing.

Q: How do you handle spare parts supply for maintenance and repairs in Europe?

A: We maintain a comprehensive inventory of high-wear components (brake pads, rotors, tires, belts, controllers, and replacement batteries) at our partner warehouse networks, ensuring standard replacement parts dispatch within 24 to 48 hours across major European markets.

Q: What is the procedure for requesting a prototype sample for evaluation?

A: Sample requests are initiated by submitting technical requirements or fleet application details. Following agreement on specification and sample pricing, units are built, tested, and dispatched via air or sea freight with a standard sample lead time of 15 to 20 business days.

Q: What anti-corrosion treatments are applied to steel frames used in wet or coastal climates?

A: All structural steel frames undergo an acid pickling and phosphating wash, followed by an electro-deposition (ED) primer coating and an exterior polyester powder coat. This multi-layer barrier prevents internal and external oxidation even when exposed to road salt and continuous moisture.
