👋 Welcome to E Bike Power UK

Looking to take your ride to the next level? 🚴💨

Our premium electric bike conversion kits are built for performance, reliability, and pure fun — designed for DIY riders who want serious power with plug-and-play simplicity 🔧✨.

⚙️ New Version – Built-In Display Limiter

This is our latest generation kit, now featuring an integrated limiter directly on the display — no more remote key needed ✅

  • Limited mode: Activate by holding the “–” button on the display for 3 seconds. Limits speed to 15.5mph (25km/h) and caps output to 250W equivalent.
  • Throttle disabled: Automatically switches off throttle when limiter mode is active for full UK road compliance.
  • Full power mode: Release limiter to unlock up to 1000W+ performance for off-road riding 🚀⚡

💡 The limiter setting is stored even after power cycling, so you stay compliant without having to reactivate it each time.

⚡ Why Choose This Kit?

  • 🔌 Plug & Play: No wire cutting or splicing needed.
  • 🔋 Universal Controller: Supports 36V / 48V / 52V setups.
  • ⚙️ Wide Compatibility: Fits rear dropouts 135–148mm, HG cassette 7–11 speed.
  • 🚴 Off-Road Beast: Built for trails, private land, and serious riding.

📦 What’s in the Box?

Inside your kit you’ll find everything you need for the ultimate DIY build:

    • 🔋 48V 19.2Ah LG Battery — 30A BMS downtube style, 3A UK charger, ~8hr charge time
    • 1000W Brushless Gearless Hub Motor (fits 135mm dropout)
    • ⚙️ HG Cassette Body (7–11 speed, spacer needed for 7)

    • 🔧 Cassette-Style Hub: Best suited to bikes that already use a cassette, allowing you to utilise all of your gears from 7 to 11 speed. The motor features an M12 axle which gives a snug, secure fit inside the rear frame dropout for improved alignment and power transfer.
