Inspect the frame for any signs of damage, especially around the hinges and folding mechanisms. Check the condition of the tyres, brakes, and gears. Ensure all folding mechanisms lock securely and operate smoothly. Ask about the bike's service history and any previous repairs.
Regularly lubricate the chain and folding hinges. Check tyre pressure before each ride. Inspect brake pads and cables for wear. Consider a professional service annually to ensure all components are in good working order, particularly the folding mechanisms.
Check the frame number, which is usually located on the frame near the bottom bracket. Contact a Brompton dealer or use online resources to verify the frame number. Be wary of deals that seem too good to be true, as counterfeit Brompton bicycles exist.
Pay close attention to the condition of the folding hinges, as these are crucial to the bike's functionality. Check for play or looseness in the hinges. Also, inspect the condition of the rear triangle and ensure it folds and unfolds smoothly. Worn tyres and brake pads are common issues but are easily replaceable.
By law, a bicycle used on public roads in the UK must have working brakes on both wheels. It is also advisable to have a white front reflector, a red rear reflector, and pedal reflectors. While not legally required during daylight hours, it's recommended to use lights (white front and red rear) for increased visibility, especially during periods of low light or at night. Consider wearing a helmet for added safety.
