🛠️ Installation Notes (Read First)

• We don’t currently supply a printed manual, but we’re happy to help if you have questions. Please review the following before you start:
  
  1- Motor–controller plug: A white plug is supplied separately. Do not connect it until you’ve trial-fitted spacers, torque arms and axle nuts. When ready, connect the plug — match colours red→red, black→black, green→green, blue→blue, yellow→yellow.
  2- Cable groups: Three thicker cables are motor phases; five thin 5V wires are the hall sensors.
  3- Connectors: Photos may show a yellow MT60. For this BMX kit we use bullet connectors (push-fit) with a silicone sleeve to allow spacer/torque-arm/nut clearance.
  4- Spacers: Gold spacers (with folded tab) can be used inside or outside the dropouts. They’re not always essential — choose what gives the best fit. The tab should locate in the dropout to help secure the axle.
  5- Dropout size: Typical BMX rear dropout is approximately 110 mm. Steel BMX frames are tough to spread — plan your spacer/washer stack accordingly. Fit both torque arms.

🔋 Battery Placement (BMX Frames)

• BMX triangles are small and usually lack bottle-cage mounts. A common solution is top-tube mounting.
  We recommend using a rivnut gun to install threaded inserts in the tube for a secure battery base.
  You’re welcome to use a different battery if it suits your needs.

🔌 Battery Compatibility & Plug-and-Play Setup

• If you purchase the kit and battery from us together, everything is designed to work plug-and-play — no cutting or joining wires required.
  The controller battery connection is XT60, so if you purchase just the kit on its own, you will need a compatible XT60 battery connection if using your own battery or one from elsewhere.
  You can also choose a different battery from our store if preferred.
  All of our batteries are compatible, and where required we supply an XT90 to XT60 adapter with our battery packs.

⚖️ 250W Street Mode

• The 250W speed limiter is now integrated directly into the SW900 display.
  
  Press and hold the minus (–) button to activate Street Mode.
  Street Mode limits pedal assist speed to 15.5 mph (25 km/h).
  The throttle is disabled and functions as a walk-assist only while Street Mode is active.
  Press and hold the minus (–) button again to return to full-power mode.
  The selected mode remains saved even after the bike is switched off and back on.
  This function is designed to HELP users comply with applicable e-bike regulations where required.
