    THE ELECTRIC ASSIST SYSTEM The Brompton Electric gives motor assistance to support the pedaling input from the rider. A sensor in the bottom bracket measures the rider’s cadence* and power, a sensor within the hub motor measures the speed of the bike. The system analyses this data to determine how much assistance the hub motor gives.

    You can also use a hand-pump, or an air-line found at petrol/gas service stations. All Brompton Electric Bicycles use a 37 x 349mm tyre (16 x 1-3/8”) and corresponding inner tube.

  • Page 26: Gears

    USING THE SHIFTERS A Brompton can be fitted with either 1, 2, 3 or 6 gears. 2-speed bikes feature a left hand shifter, 3-speed bikes a right hand shifter and 6-speed bikes use both a left and right hand shifter.
  • Page 27 3-SPEED GEAR SHIFTER ƒ 3-speed shifters are used on 3 and 6-speed bikes ƒ If you are unsure about any fitting or operation instructions please contact a Brompton dealer USING THE SHIFTER The 3-speed shifter uses a self-returning lever to change between the three gears.

  • Page 32: Brakes

    You should adjust your brakes on a regular basis as they are critical to your safety. The time between adjustments will vary depending on how often you use your Brompton; if your brake lever touches the handle bar when you pull on it, your brakes need urgent adjustment. The brakes should be set so that the brake pads are as close to the rims as possible without interfering with the rotation of the wheels.
  • Page 33 Correct cable routing and cable housing length is essential; cables must pass in front of the handlebar, to the left of the handlebar support and to the right of the main frame tube. IF YOU ARE UNSURE ABOUT ANY OF THESE ADJUSTMENTS CONSULT YOUR BROMPTON DEALER, DO NOT ATTEMPT TO USE THE BIKE WITH POORLY ADJUSTED BRAKES Fig.
  • Page 34 LIGHTING A Lighting system is available for the Brompton Electric; a front and rear lamp, powered by the battery. These can be added to bikes not originally equipped with a lighting system, this work can be carried out by an authorised Brompton Electric Dealer.

  • Page 35: Front Luggage

    • When the front luggage is loaded, the steering and braking may behave differently • The Brompton Electric luggage is compatible with all handlebar configurations • Do not attempt to use the Brompton Electric luggage, or Brompton Electric front carrier with any other bicycle EFCB Fig.

  • Page 36: Rear Luggage

    REAR CARRIER PLATFORM The rear carrier platform has a load capacity of 10kg. It mounts to the rear frame in two points, the brake tube (fig. 29) and the dropouts (fig. 30). The rear mudguard mounts to the rack (fig 29, 31) in two positions. Before starting it is worth removing the rear wheel from the bike in order to make it easier to fit or remove the rack, information on this can be found on page 38.

  • Page 37: Cleaning & Lubrication

    When lubricating your Brompton, avoid getting oil or grease on the seatpost or the wheel rims. Any good quality general purpose grease is satisfactory. For the chain, ‘dry’ chain lubricants with good penetrating properties give the best results.
  • Page 38 Do not submerge the bike, hub motor or battery in water; this can allow water to enter the motor, battery and electrical systems. This could cause overheating bursting or ignition. Do not place the battery or bag down on a wet floor, this could allow water onto the battery connector. Do not use the bike if it has been submerged in water.
  • Page 39 The notch in the side of the Brompton Electric battery is for strain relief (fig. 33) for the USB cable. This may be used to control the cables in the bag and prevent damage if the battery is attempted to be removed with the usb cable still attached.

  • Page 44: Rear Wheel - Removal And Fitting

    REAR WHEEL – REMOVAL AND REFITTING When removing the rear wheel it is easiest to do with the bike in a workstand to lift it from the floor, or with the bike in the parked position (see folding instructions) so that the bike can support itself. If the tyre is deflated it can pass through the brake pads more easily.
  • Page 45 STURMEY ARCHER 3 SPEED ADJUSTMENT Fig. 47 Adjustment is carried out by slackening the lock nut N, turning the barrel B (fig. 45) to obtain correct setting, and relocking the nut N. Ensure the indicator rod is the correct length for the hub-type.

    FRONT WHEEL – REMOVAL AND REFITTING When removing the front wheel it is easiest to do with the bike in a workstand to lift it from the floor, or with the bike in the parked position so that the bike can support itself. If the tyre is deflated it can pass through the brake pads more easily.
  • Page 47 FITTING THE WHEEL Make sure the wheel is in the correct orientation with the motor cable on the left hand side of the fork (fig. 48), next to the plastic hook. Fig. 49 Push the axle into the dropouts, ensuring that the washer is on the inside of the dropout and that the wheel is fully inserted on both sides.

  • Page 48: Routine Replacements

    ALUMINIUM COMPONENTS As on other lightweight machines, aluminium alloy is used in the construction of the Brompton, and this material has a finite design life before failure. In normal use, the risk of aluminium fatigue failure is remote, even after many thousands of miles. However, the risk of failure increases with use, especially with hard riding or other severe loading.
  • Page 49 The worn sleeve can eventually cause damage to the frame itself if not replaced. Replacing the sleeve requires specialist tools and should be done by an authorised Brompton dealer. REAR HINGE Over time the bushes in the rear frame pivot can wear, slight play will become detectable. In order to remove the play the bushes need to be replaced.

  • Page 50: Warranty

    (in the case of the frame) or two years (in the case of other parts) of the date of first purchase of the bicycle. The Brompton is for use on roads and well-made paths. It is not designed for cross-country riding: this can overstress the frame, and the tyres and wheels are unsuitable.
  • Page 51 8. Defects caused by faulty adjustment, or repairs and alterations performed by a non-authorised Brompton Electric Dealer, are not covered by this warranty. 9. Defects caused by the use of parts and accessories not authorised by Brompton Bicycle Ltd are not covered by this warranty.
