The multifunction handlebar switch provides ECO/TURBO selection, mode switching and single/dual motor control logic in a single compact module compatible with both Dualtron and ROVORON control systems. Electrical contacts and an isolated encoder are specified for high cycle life and resistance to ingress, matching the wiring harness interfaces used on Spw 4, Spw 5 and the various Kullter platform variants.Housing design uses impact-resistant polymer with sealed switch caps and reinforced mounting tabs to minimize flex under aggressive control inputs. The unit supports both single and dual motor configurations and is pin-compatible with existing handlebar clusters to simplify retrofit or replacement operations.Compatible Models: Kullter Kullter 23.4Ah Kullter Luxury 30Ah Spw 4 Spw 5 .faq-accordion { max-width: 900px; margin: 40px auto; } .faq-item { border-bottom: 1px solid #ddd; } .faq-item input { display: none; } .faq-item label { display: flex; justify-content: space-between; align-items: center; padding: 16px; cursor: pointer; font-weight: 600; background: #f9f9f9; } .faq-item label::after { content: "+"; font-size: 22px; transition: transform 0.3s ease; } .faq-item input:checked + label::after { content: "−"; } .faq-content { max-height: 0; overflow: hidden; transition: max-height 0.35s ease; padding: 0 16px; } .faq-item input:checked ~ .faq-content { max-height: 500px; padding-bottom: 16px; } .faq-content p { margin: 12px 0; } Shipping France Standard: €8.99 (Free over €149) Delivery time: 3–5 working days France (Express) Price: €12.99 Delivery time: 2–3 working days Europe & International From €11.99 Delivery time: 3–7 working days Price & eligibility calculated at checkout Please confirm compatibility with your electric scooter model before ordering to avoid installation issues.
