Buying a bike online often raises one important question: how much assembly will I need to do when it arrives?
Selected bikes at North Sports are supplied approximately 85% assembled by the manufacturer. This means the more complex parts of the bike have already been installed, while a small number of components are positioned or removed so the bike can be safely packaged for delivery.
The exact setup can vary between models, but this guide explains what you can generally expect from a partially assembled bike and what needs to be checked before your first ride.
What does 85% assembled mean?
An 85% assembled bike is substantially built before it reaches you.
Components such as the frame, drivetrain, chain, crankset, rear wheel and much of the braking and gearing system are normally already installed. Brake and gear cables will also generally have been routed and connected.
To fit securely inside its delivery box, however, some components may require final installation or adjustment.
Depending on the individual bike, this can include:
- Front wheel
- Handlebars
- Pedals
- Seat post and saddle
- Correct positioning of the front fork
- Tyre inflation
- Final brake, gear and safety checks
The exact assembly requirements vary by bike, so always follow the manufacturer instructions supplied with your particular model.
Why aren't bikes delivered completely built?
A fully assembled adult bike is a large and awkward item to transport.
Partially assembling the bike allows manufacturers to package it securely into a purpose-designed bike box, helping protect the frame and components while making transportation more practical.
Protective packaging is normally used around the frame and components to reduce movement during transit.
Once unpacked, the remaining components can then be installed and the bike prepared for use.
What will I need to do when my bike arrives?
Although individual models differ, completing a partially assembled bike will normally involve some of the following steps.
1. Carefully unpack the bike
Remove the bike and all separate components from the packaging.
Protective material and cable ties may be fitted around the frame, wheels and other components. Remove these carefully to avoid damaging the paintwork, cables or brake hoses.
Before starting assembly, check that all components and accessories are present.
2. Position the fork and handlebars
The handlebars may be removed or positioned differently for transportation, and the fork may need rotating into its correct riding position.
The handlebars will then need to be positioned correctly and securely tightened.
Take particular care to make sure the handlebars and front wheel are correctly aligned.
3. Fit the front wheel
The front wheel may need installing into the fork.
The exact method depends on the axle and braking system fitted to your bike, so follow the instructions supplied by the manufacturer.
If your bike uses disc brakes, additional care should be taken when positioning the brake rotor between the brake pads.
4. Install the seat post and adjust the saddle
Insert the seat post into the frame and set the saddle to an appropriate starting height.
Always observe the minimum insertion marking on the seat post and ensure the seat post clamp is securely tightened before riding.
The saddle height can then be fine-tuned once the rider is on the bike.
5. Fit the pedals
Pedal installation is straightforward, but it is one of the areas where particular care is required.
Bicycle pedals are normally marked L for left and R for right.
The right pedal uses a conventional thread, while the left pedal uses a reverse thread. Fitting a pedal to the wrong side or forcing the thread can damage the crank arm.
Make sure each pedal is fitted to the correct side and securely tightened.
What tools might I need?
The tools required will depend on the individual bike, but commonly used tools include:
- Metric Allen keys
- 15mm spanner or suitable pedal wrench
- Bicycle pump
- Scissors or suitable cutters for removing packaging and cable ties
- Bicycle grease for appropriate threaded components
Check the instructions provided with your bike before beginning assembly.
Do I need to adjust the gears and brakes?
Your bike's main braking and gearing components will normally already be fitted, but final safety checks should always be completed before riding.
Check that:
- Both brakes operate correctly
- Brake pads or rotors are correctly positioned
- Both wheels are securely fitted
- The handlebars and stem are securely tightened and aligned
- Pedals are fitted correctly and securely
- The seat post and saddle are secure
- Gears shift correctly
- Tyres are inflated to an appropriate pressure
- All relevant bolts and fasteners are secure
These checks are important even where a bike has been substantially assembled before delivery.
What if I don't want to assemble the bike myself?
We understand that not everybody is comfortable completing the final assembly of a new bike.
Where available, North Sports therefore offers a Fully Assembled Delivery option when ordering selected bikes.
Choose the fully assembled option on the product page and the bike will be professionally assembled and checked before being prepared for delivery.
If you are unsure which delivery option is right for you, our team can help before you order.
Which North Sports bikes does this apply to?
This delivery method is used on selected bikes from brands including:
- Claud Butler
- Dawes
- Falcon
- HOY
- Squish
Always check the Bike Assembly option displayed on the individual product page before ordering. Other bike brands and models sold by North Sports may use different delivery and assembly methods.
Should I assemble the bike myself or use a cycle mechanic?
If you're confident carrying out basic bicycle assembly and have the appropriate tools, completing the remaining setup may be something you're comfortable doing yourself.
However, correct assembly is essential for safe operation.
If you are uncertain about fitting or adjusting any component, we recommend either selecting Fully Assembled Delivery where available or asking a qualified cycle mechanic to complete and check the bike before it is ridden.
This is particularly important if you have any concerns about the brakes, steering, wheels or drivetrain.
Before your first ride
Before riding your new bike for the first time, carry out a complete safety check.
Make sure the wheels, handlebars, pedals and saddle are securely fitted, test the brakes, check the gears and ensure the tyres are correctly inflated.
For children's bikes, a responsible adult should always check the bike before the child rides it.
Your bike's manufacturer instructions should always be followed where they differ from the general guidance provided here.
