Our Assembly Instructions in a Few Simple Steps
We want to get on our bikes quickly too — so here’s a handy tip: the bike icons show you which steps apply to your model.
1. Preparation
The Tools for Assembly/Adjustment – You Don't Need Much at All
 | - A pedal wrench or 15 mm open-end wrench, a 4 mm, 5 mm, 6 mm, 8 mm Allen key, a T25 Torx and a pair of scissors or a side cutter respectively.
- Recommendation: a torque tool with appropriate bits for maximum safety and protection of sensitive components.
- Buy the right tools now in your favorite shop!
|
Opening and Unboxing – The Tension Rises
 | - First open the shipping box (beware of the packaging clips).
- Next, please remove the accessory box, if included (contains e.g. pedals, manual or warranty card).
- Then you can take out the padding material and fold down the pre-perforated side panel.
|
Lifting the Bike out – The Moment of Truth
 | - Thanks to the fold-down side wall, you don't have to lift your bike very high.
- If your bike is a bit heavier, such as an e-bike, ask a friend to help you lift it.
|
Removing the Bubble Wrap – Your Bike Strips Off
 | - Now it's time to use your scissors or a side cutter.
- Carefully cut the tapes or cable ties on the stem, saddle and frame.
- Remove the protective foil.
- Attention: the handlebars are also attached to the top tube, so be especially careful with the cables and hoses.
|
2. Assembly
Handlebar Mounting – How to Keep Everything under Control
 | - First loosen the stem bolts with a 4 or 5 mm Allen key or Torx T25 key.
|
 | - Place the handlebars in the centre (oversized part) of the stem with its marks facing in the riding direction.
- Next, put on the stem face plate and tighten it so that you can still easily turn the handlebars.
- For carbon parts: check whether assembly paste has already been applied to the clamping surfaces or apply some if necessary.
|
 | - Check that the handlebars are centred.
- Helpful scales are printed on most handlebars.
- Otherwise, the oversized clamping area should stick out just as far on the left and right.
|
 | - Start tightening the stem bolts with a 4 or 5 mm Allen key or Torx T25 key.
- Tighten the (usually 4) bolts evenly in a cross pattern (bottom left & top right, bottom right & top left).
- If you do not find a "No-Gap" label, make sure there is an even gap between the face plate and the stem body.
|
Mounting the Pedals – Very Simple, with the Right Turn
 | - Please note: If pedals are included depends on the model.
- First screw the left pedal to the left crank arm.
- The crank side and the matching pedal are both marked with a dot in the same color.
|
 | - Now screw the right pedal to the right crank arm.
- The matching parts are also marked with a dot in same color.
|
Tightening the Pedals – Two Quick Steps
 | - Apply the 15 mm pedal wrench or, depending on the version, a 6 mm or 8 mm Allen key to the axles.
- Tighten with the torque recommended by the manufacturer – usually 30 Nm – in the riding direction.
|
Installing the Saddle and Post – Easy as Pie
 | - Open the seat clamp with the quick-release lever or with a 4 mm or 5 mm Allen key or T25 Torx in an anti-clockwise direction.
- Pull out the saddle to about hip height and tighten it again moderately.
- As a starting point, we pre-assemble the saddle horizontally for you.
- You can usually also adjust the saddle tilt and fore aft position using a 5 mm or 6 mm Allen key or T25 Torx on the underside.
|
Mounting the Front Wheel – Rarely Necessary, Easily Done
 | - First remove the through axle or quick release and the transport lock on the brake – please do not pull on the brake lever afterwards
|
 | - Insert the front wheel via the so-called dropouts (openings) on the underside of your fork.
- Next, fit the quick-release or thru axle through the dropouts and hub.
- Tighten the axles with quick-release levers so that the lever, which is slightly under tension, can be closed completely to the fork leg with moderate force.
- If your axle is 100% bolted, use the 6 mm Allen key and check with a torque tool.
- If you have bought an Enduro or DH bike, it may also be necessary to tighten the pinch bolts on the dropouts with a 5 mm Allen key.

3. Adjustment
Adjusting the Rotation of Road Handlebars – Comfortable & Aerodynamic
 | - Turn it up or down so that you can comfortably reach the shift/brake levers.
- Ideally you should be able to reach the bar grips with a straight back by only moving your pelvis.
- lRelaxed wrists allow for optimal blood circulation.
|
Adjusting Straight Handlebars – Control & Ergonomics
 | - Turn it up or down so that you can comfortably grip the shifters and brake levers.
- In the best case you can actuate all levers with your fingertips.
- Straight wrists (forearm and fingertips form a line) allow for optimal blood circulation.
|
Adjusting the Saddle Height – How to Sit Correctly for the Test Ride
 | - Put on the shorts or pants and shoes you want to ride with, and get on your new bike.
- Next, place your heels on the pedals.
- When turning the crank to the lowest point (6 o'clock), the legs should be fully extended.
- If this is only possible with a lateral pelvic tilting movement, the saddle must be adjusted a little lower.
- For further tips please take a look at our ergonomics topic page

Bike Assembly Before Delivery
Once you place your order at BIKE24, your bike arrives almost ready to ride. Before it leaves our shop, our mechanics handle most of the assembly: adjusting the derailleur, greasing and setting the headset, and tightening every bolt to spec. In other words, you’ll receive a bike that’s practically fully assembled. Here’s a closer look at what our team checks before shipping.
To give you a look behind the scenes, here’s what our team checks before shipping:
- Centering and truing the wheels
- Lubricating and adjusting the headset
- Adjusting brakes and shortening cables if needed
- Setting up gears and derailleur
- Adjusting the suspension (preset for an 85 kg rider)
- Checking every bolt for proper torque and fit
- Testing lights
- Wrapping bar tape on road bikes
- Updating electronic drivetrains
- Installing and leveling the saddle
Finally, we log the frame number and complete at least two independent test rides.
We then ship the bike straight to you. The last few steps are simple, so you can finish assembly quickly and without any prior experience — whether it’s a road bike, mountain bike, or another style of bike.
Electric Bike Assembly/First Charging of the E-Bike Battery
E-bikes get the same complete assembly and careful inspection as our other bikes — plus a full system check. We test the motor support levels, walk assist, lights, display, and control buttons, and install any necessary software updates before shipping.
Proper charging is key to long battery life. That’s why BIKE24 manage stored e-bikes with regular recharges, always following the manufacturer’s guidelines. Your e-bike is shipped with about 50% charge, ready to go, and of course the charger is included.
How Your Bike Is Boxed for Shipping
To keep our wide range of bikes in stock and easy to assemble, every bike ships in a specially designed, sustainable box with plenty of padding. The box’s smart dimensions allow us to pack most bikes with the wheels, saddle, and seatpost already installed. In most cases, only the handlebars are removed from the stem and securely fastened to the top tube with protective packaging.
