Varstrom Z8 750W Mid Drive Ebike Conversion kit Tong/-Sheng Mid Drive Kit

• New Upgrade : This upgraded unit uses a 1T4 main cable compatible with Tong/-sheng‑protocol displays. Improved contact stability reduces after‑sales issues by 15%. Its bidirectional freewheeling clutch eliminates traditional one‑way clutch drag for smooth motor‑off pedaling. The reinforced external nylon clutch handles higher torque for better performance. With over 80% efficiency, low wear and quiet operation, it delivers stable long‑term cycling reliability
• Universally Compatible 68mm/73mm Bottom Bracket : Fits standard JIS bottom brackets measuring 68mm or 73mm in length , 33.5mm–36mm inner diameter , 10.5mm thickness — the most common spec across MTBs, road bikes, city commuters, and hybrids. This mid-drive motor kit is not compatible with carbon fiber or wooden bike frames.Mid-drive placement preserves natural weight distribution and handling balance. Basic accessory kit included for straightforward installation. Battery sold separately.
• 140N.m Torque‑Sensor Mid‑Drive Motor : It produces 140N.m peak torque for easy climbing and quick acceleration, hitting 55km/h max on flat ground. Its precise torque sensor reads pedal pressure in real‑time and adjusts power instantly. Harder pedaling brings more power; power stops once pedaling ceases. It provides natural, smooth riding like a standard bike with electric assist. Great for city commuters, mountain bikers, hilly‑area riders and users needing strong climbing ability
• Centralized Weight & Modular Safety : Mid-drive motor centers mass low and between the wheels for balanced handling and stable cornering. Integrated cadence sensor with sealed waterproof housing — no exposed intermediate connectors. Motor output aligns directly with crank rotation and stops immediately upon pedal release. During crank idling, motor remains stationary for predictable, bicycle-like safety behavior
• 3 Riding Modes with EKD01 Smart Display : Throttle mode for motor-only cruising, Pedal Assist with torque-responsive power matching your effort, and Bike mode for traditional cycling. EKD01 display upgrades from VLCD-5, built-in navigation, Type-C charging port, 4-level brightness adjustment, and multilingual interface. Sync with your phone for ride data tracking and route planning
