⚙️ New Version – Built-In Display Limiter

• This is our latest-generation kit, now featuring an integrated limiter directly on the display — no remote key is required ✅
  ✅ Limited mode: Activate by holding the “–” button on the display for approximately 3 seconds. This limits the speed to 15.5mph / 25km/h and caps the output to a 250W equivalent.
  ✅ Throttle disabled: The throttle is automatically disabled while the limiter mode is active.
  ✅ Full-power mode: Deactivate the limiter to unlock up to 1000W+ performance for use on private land and off-road areas where permitted 🚀⚡
  💡 The limiter setting is stored after the system is switched off, so it does not need to be reactivated every time the bike is powered on.

⚡ Why Choose This Kit?

• 🔌 Plug and Play: No wire cutting or splicing is normally required.
  🔋 Universal Controller: Supports 36V, 48V and 52V setups.
  ⚙️ Wide Compatibility: Designed for rear dropouts measuring approximately 135–148mm.
  🚴 HG Cassette Compatible: Suitable for 7–11-speed cassettes.
  🚀 Powerful Performance: Ideal for trails, private land and serious off-road riding.

  The motor features an M12 axle, designed to provide a secure fit inside a suitable slotted rear dropout for improved alignment and power transfer.
  
  Please note that the cassette itself is not included. The tools required to remove your original cassette and install it onto the new motor wheel are supplied with the kit.
