Swing the rear wheel under the frame by turning the handlebars slightly to the left, setting the driveside pedal to 8 o’clock, and lifting the rear end of the bike while releasing the lever behind the seatpost. (If you have mudguards, lift the rear end high enough and guide the wheel to prevent the mudguard flap from scraping on the ground.)

Jake’s Bonus Tips: The most effective place to stand while folding a Brompton bike is on the left (if you’re left-handed, try standing on the right side!).

Unscrew the mainframe clamp and hold the stem above the clamp while lifting the front of the bike slightly. Swing the front of the bike towards you and make sure the hook is in contact with the chainstay.

This is the fun part – loosen the handlebar clamp to release the handlebar, then let it swing into place. The weight of the handlebar will secure it into the locking notch.

Release the clamp and lower the seatpost into the frame to lock everything in place. This interlocks the folding mechanism and allows for a compact fold. (Remember to engage the clamp again after lowering.) 

Fold the left side pedal by pushing the centre and lifting it – this will prevent any unwelcome shin strikes when carrying your Brompton. Listen for a click to ensure it is folded.
