Built with care: Our mechanics fully assemble your bike before it's carefully packaged and shipped to you.

At Tweeks Cycles, we ensure your bike arrives fully assembled and, most importantly, well packaged so it arrives with you as it left us.

Upon delivery, simply unpack it, attach any included pedals (believe it or not, some bikes don’t come with pedals!), adjust the handlebars, and you're ready to ride!

It’s all super simple!

BUT! Please take extra care when fitting any pedals that are provided with your bike. Pedals are side specific and MUST be fitted to the correct side of the bike. They are usually clearly labelled Left and Right. Failure to do so will permanently damage the bike, void the bikes warranty and lead to many tantrums, for children or grown children alike!

Comprehensive 14-Point Inspection

Each bike undergoes a meticulous 14-point inspection to guarantee optimal condition and performance:

  • Ensure Cycle is free of any mechanical damage, paint chips or missing parts
  • Grease seat tube, secure seat clamp, make sure the saddle is level and ensure all fixings are secure
  • Ensure handlebar, stem and brake/gear levers are secured
  • Assess headset for play or tightness
  • Ensure handlebar tape or grips are fitted securely
  • Ensure wheel nuts, quick-release levers or through axles are tightened (please note: some adult mountain bikes come with the front wheel removed for transport), true the wheels for optimal alignment and check wheel bearings for proper adjustment
  • Inflate tyres to the correct pressure
  • Ensure front and rear brakes operate correctly. Bleed hydraulic brakes if required
  • Ensure pedal threads are greased
  • Test all gears to ensure smooth operation
  • Check suspension system for correct operation and ensure bolts are tight (if required)
  • Ensure smooth bottom bracket rotation with no free play and secure crank bolts
  • Check cable/house routing and that cable ends are fitted
  • Install reflectors and bell

This thorough process ensures your bike is in peak condition upon arrival. We do not fit mudguards or other accessories prior to shipping as these are likely to be damaged in transit.

Note on Electric Bikes

Due to shipping restrictions, in some circumstances you may receive your new electric bike and its battery separately. This is due to carriage restrictions on some removable batteries.

Note on Balance Bikes

Balance bikes are shipped unassembled, allowing you to enjoy the building experience and retain the original packaging-perfect for gifting.

Details

The SpeedBox 1.2 removes your e-bike’s speed limiter, allowing for unlimited top speed. It connects via the E-Tube port (also accommodates e-bikes without a spare E-Tube port, see below) bikes without  and displays real-time speed up to 23 km/h. Designed with new hardware and firmware, it ensures seamless integration with Shimano motors.

Key Features and Benefits:

  • Removes speed limits on your e-bike: The SpeedBox 1.2 suppresses the factory-set speed restriction. This allows you to ride without artificial limits.
  • Retains real-time speed data up to 23 km/h: Your display continues to show accurate speed values up to 23 km/h. Above this, your speedometer may display altered data.
  • Standard version for E-Tube port connection: This model plugs directly into your motor’s spare E-Tube port. It ensures a clean, reliable installation with minimal wiring.
  • +E-Tube port version for specific e-bikes: If your e-bike lacks a free E-Tube port, select the “+E-Tube port” version. This allows for proper connection in all compatible Shimano models.
  • Light-controlled activation and deactivation: The tuning chip switches on and off with your bike’s lights. This makes it easy to enable or disable the speed boost whenever needed.
  • Firmware and hardware redesigned for better performance: The latest SpeedBox model includes updated components. This results in smoother function and greater reliability over previous versions.

Enhancing your Shimano-powered e-bike with the SpeedBox 1.2 gives you full control over your ride. It eliminates restrictive speed caps while maintaining real-time speed data up to 23 km/h. This tuning chip is a practical upgrade for riders seeking unrestricted performance.
