SECTION B: FOLDING AND UNFOLDING.

If you have not had the Brompton demonstrated or explained to you, read

this section before trying to unfold or fold the bike. If you have used a

Brompton before, part 3 may still be a useful source of tips.

Part 1: ORDER OF UNFOLDING & FOLDING - OVERVIEW.

a) UNFOLDING:

Stage 1: raise saddle & handlebar and (if a folding pedal is fitted) unfold

pedal: these items can be dealt with in any order, but they must be

unfolded before moving on to stage 2.

Stage 2: unfold front wheel. The bicycle is now in its "parked" position and

ready for use.

b) FOLDING:

Always "park" the bike by swinging the rear wheel under before folding:

Stage 1: fold back front wheel (right hand pedal should be moved out of

the way if necessary).

Stage 2: lower handlebar & saddle and, if fitted, stow folding pedal; again,

these items can be dealt with in any order once the front wheel has been

folded back and latched onto the rear frame.

Part 2: OTHER POINTS TO REMEMBER.

1. The seat pillar, when folded, is what locks the folded package together: it

projects down from the main frame, so preventing the rear frame from

rotating. So, if the seat pillar is projecting below the main frame, DON'T try

to park or unpark the Brompton: also DON'T try to latch or unlatch the front

wheel from the rear frame, as this requires that the rear frame rotates

relative to the main frame. Also if the saddle is not fully down, the folded

package may fall apart when you pick the bike up.

2. The folded bicycle can be carried by the main tube. Alternatively grip the

front of the saddle, but to do this re-clamp the seat pillar after folding (best

with the saddle pointing slightly rightwards, over the centre of gravity).

3. Turning the cranks/pedals to get the RH pedal out of the way when the

bike is parked: on any bike you can back-pedal, but if the bike has

mudguards, you can also move the pedals forward. Note that:

a. the LH pedal should not be folded when turning the cranks, as it can

catch on parts of the rear frame

b. if back-pedalling, particularly with a new hub-gear in top, turning the

cranks quickly can cause the chain to go slack, or even come off. To

avoid this, keep the bike in middle gear when folding, or else (if

possible) pedal forwards instead.
