The Brompton bike’s ingenious design allows for a remarkably compact fold, perfect for navigating busy streets or storing in tight spaces. The folding and unfolding process, while initially intricate, becomes simple with practice.
The Brompton Fold: The Perfect Travel Companion
All Brompton bikes share the same straightforward folding mechanism. With a bit of practice, you can fold or unfold your Brompton in under 20 seconds. The folded bike is a neat, secure package that’s easy to carry or store. The design cleverly protects the chain and gears, keeping them clean and preventing any grease or grime from transferring onto your clothes or luggage. This makes Brompton bikes ideal for commuting or travel, as they can be easily taken on public transport or stored in a car, ready for your next adventure.
Unfolding Your Brompton Bike
Unfolding your Brompton is a breeze, even if it’s your first time. Let’s transform your compact Brompton into a ride-ready bike.
1. Position the Bike
- Place your folded Brompton on a flat, stable surface.
- If you have an electric model or a Brompton converted to electric with a kit, keep the battery nearby for later attachment.
2. Unfold the Left Pedal
- Identify the folding pedal on the left side of the bike. It’s cleverly designed with a toothed metal cage.
- Gently pull this cage towards you until you hear a satisfying click, indicating the pedal is securely extended.
3. Unfold the Main Frame
- Locate the main frame hinge clamp at the bike’s center. Turn its lever counterclockwise to open it.
- Now, for a bit of coordination: place your right hand on the saddle and your left hand near the hinge on the handlebar stem.
- Peer down where the chain runs between the wheels. You’ll spot a black hook securing the front wheel to the frame.
- Gently lift the handlebar stem with your left hand, raising the hook above the tube it rests on.
- With a smooth, arcing motion, swing your left hand away from you, pushing the front wheel forward. Continue until the main frame hinge closes completely.
- The front wheel should now be aligned with the rear wheel. Securely tighten the hinge clamp lever.
4. Unfold the Handlebars
- Find the handlebar hinge clamp near the front wheel. Loosen it by turning the lever counterclockwise.
- Raise the handlebars to their upright riding position.
- Ensure they’re straight and then firmly tighten the clamp to lock them in place.
5. Extend the Seatpost
- Flip the seatpost clamp lever open.
- Raise the seatpost to your preferred riding height, ensuring the saddle is aligned with the frame.
- Close and securely tighten the seatpost clamp.
- Remember, the extended seatpost acts as a secondary lock, keeping your Brompton unfolded and ready for action.
6. Secure the Rear Wheel
- Grip the handlebar with your left hand and use your right hand to swiftly lift the bike by the saddle.
- Swing the rear wheel backward until it locks into its riding position with an audible click.
- Gently press down on the saddle to ensure the suspension block is fully engaged with the main frame.
7. Attach the Battery (if applicable)
- Align the battery with the mounting bracket on the frame, ensuring the connection points match.
- Slide the battery downward onto the mount until it clicks into place.
- The battery will automatically engage once connected.
While Brompton bikes don’t have a built-in level indicator for the seatpost, you can ensure consistent saddle height after each unfold by marking the desired position with a small piece of tape or a permanent marker. This will save you time and ensure a comfortable ride every time.
Folding Your Brompton Bike
Time to pack up your trusty companion. Follow these steps to fold your Brompton neatly and efficiently, ready for easy storage or transport.
1. Remove the Battery (if applicable)
- Press and hold the release button on the battery mount.
- Carefully lift the battery away from the frame and store it safely.
2. Position the Right Pedal and Handlebars
- Turn the cranks until the right pedal is pointing downwards (at the 6 o’clock position).
- Gently turn the handlebars slightly to the left, ensuring they’re not parallel with the rear wheel.
3. Lower the Seatpost
- Open the seatpost clamp.
- Lower the seatpost all the way down until it rests on the rear frame.
- Close and tighten the seatpost clamp.
4. Fold the Handlebars
- Loosen the main frame hinge clamp by turning the lever counterclockwise about 4-6 turns.
- Open the handlebar hinge clamp.
- Carefully rotate the handlebars downward and towards the left side of the front wheel.
- Ensure they rest neatly alongside the wheel and then tighten the handlebar clamp.
5. Fold the Main Frame
- With the main frame hinge clamp still loosened, swing the front wheel backward towards the rear wheel.
- You’ll feel a locking hook engage, keeping the frame folded.
- Now, tighten the main frame hinge clamp securely.
6. Fold the Rear Wheel
- Stand on the left side of the bike.
- Locate the small black lever behind the seat clamp and press it forward.
- In one swift motion, lift the back of the bike by the saddle. The rear wheel will cleverly swing underneath the frame.
- Gently lower the bike so it rests on the ground in its folded position.
7. Secure the Folded Bike
- Check that all clamps are closed and tightened.
- The folded bike should be compact and hhold together firmly for easy carrying or storage.
