Unboxing your new Himiway D5 2.0 is a great feeling. But turning a box of components into a fine-tuned, road-ready e-bike can get messy.
To make your assembly process easier, I've created a comprehensive roadmap based on the official owner's manual. I've included the granular, step-by-step instructions you need, so you can build with confidence.
In this guide, we're going to discuss:
- What's in the Box
- Handlebar Installation
- Front Light & Bell Installation
- Front Wheel Installation
- Front Fender Installation
- Left & Right Pedal Installation
- Charging Your Battery
- Tire Pressure Check
- Control Adjustment
- Comfort Adjustment
- Assist System Operation Guide
- Installation Verification
What's in the Box: Your Pre-Assembly Checklist
Before you start, let's do a quick inventory. Laying everything out gives you a clear picture of the project ahead and ensures nothing is missing.
Your package should include these items:
-
Essential Components
- An e-bike (D5 2.0 or D5 ST 2.0), not fully assembled；Owner's Manual；Charger；Pedals (a pair)；Headlight
-
Complimentary Accessories
- Bell；Hex wrench；15mm Wrench；Drawstring Bag；A bike-specific screw set
Pro Tip: I highly recommend removing the battery before you begin assembly. This reduces the bike's weight, making it easier to maneuver, and prevents potential damage to the battery during the process.
Handlebar Installation and Positioning
Your handlebars are your control center. Getting them installed correctly is the first major step to getting your bike ready to ride.
Here are the precise steps from the manual to get it done right:
- Remove the Stem Cap. Use a 4mm Allen key to take off the handlebar stem cap.
- Insert & Pre-Lock the Handlebars. Put the handlebar into the stem. Pre-lock it, making sure it's firmly in place with no wobbling.
- Align with Crosshairs. Adjust the handlebar to line up with the stem's crosshairs.
- Tighten the Stem Cap (X-Pattern). With a 4mm Allen key, tighten the stem cap following an X-shaped sequence (e.g., top-left, bottom-right, top-right, bottom-left). The manual recommends a torque of 12-18 Nm for the handlebar.

Front Light and Bell Installation
Let's get your visibility and safety features installed.
How to Install the Front Light
Here’s the step-by-step process:
- Remove the fixing bolts of the headlight.
- Align the screw holes of the headlight with those of the bracket on the riser, insert the bolts, adjust the irradiation angle, and then lock the bolts.
- Finally, connect the headlight power cables in the direction of the arrow by plugging them into each other.
How to Install the Bell
The bell can be easily mounted on the handlebar near one of the grips for quick access. Use the provided screw to clamp it securely in place.
D5 2.0 Front Wheel Installation
This step is critical to your safety, so take your time here. I find having a helper makes this process much smoother, but it can be done solo.
Step-by-Step Installation Guide:
- Loosen the bolts of the meter bracket, then rotate the meter so that it is below the horizontal plane of the handlebar.
- Carefully flip your bike upside down for the front wheel installation.
- Remove the spacer from the brake caliper.
- Insert the front wheel into the front fork. Seat the hub axle into the dropouts. Ensure the disc brake rotor is properly aligned and centered within the caliper.
- Tighten and secure the front cap nut with the socket wrench. The recommended torque is 30-35 Nm.
Pro Tip: If you have two people, there's no need to flip the bicycle. One person can lift the front of the bike while the other places the front wheel directly below the fork, carefully slotting the axle into the dropouts and ensuring the brake rotor inserts properly into the caliper. Then, just tighten the bolts.
Front Fender Installation
The front fender (or mudguard) keeps you clean from road spray.
How to Install the Front Fender:
- Please flip the bicycle again to stand it upright on the ground.
- Attach the fender bracket to the fork crown and tighten the screws with a 5mm Allen key. The recommended torque is 14-15 Nm.
- Use a 5mm Allen key to secure the fender stays on both sides of the fork arms. Ensure the stays are aligned parallel to the wheel axis for stable mounting.

Left & Right Pedal Installation
This seems straightforward, but it's a common place to make a mistake. The pedals are side-specific to prevent them from loosening as you ride.
Follow These Steps Carefully:
- Identify Pedals. Check the "L" or "R" sticker on the pedal axle to distinguish left and right pedals.
- Install Right Pedal. Hand-tighten the right pedal clockwise, then use a 15mm wrench to secure it.
-
Install Left Pedal. Thread the left pedal in counter-clockwise by hand, and tighten with a 15mm wrench to 35-40 Nm.

Charging Your Battery
Before you hit the road, you'll need a full charge. You can charge the battery either on or off the bike.
How to Remove the Battery:
- Find the keys located on the handlebar and remove them.
- To remove the battery, first support the lower battery casing with your palm.
- Insert the key and turn it counter-clockwise by a certain angle.
- Then, press down on the key and turn it again to detach the battery.
Charging Methods:
-
On the E-bike: Open the rubber cover on the charging port, insert Plug 1 from the charger, and then plug the charger's Plug 2 into a household socket.
-
Off the E-bike: After removing the battery, the procedure is identical.
The charger's indicator light is red during charging and turns green when fully charged or disconnected.
You can get more information about battery charging and maintanence by our guide.

Tire Pressure Check
Proper tire pressure is the foundation of a safe, efficient, and comfortable ride.
How to Check and Inflate:
- Squeeze the tire. If it compresses easily, inflate it.
- Use a pump with an AV interface.
- Inflate until the tire resists compression, but don't exceed the max pressure listed on the tire.
- Follow the tire pressure markings on the tire sidewall: 50-210 kPa (8-30 psi / 0.5-2.1 bar).

Control Adjustment
This is where you fine-tune the bike's handling to suit your riding style.
Stem Angle Adjustment:
- Use a 6mm Allen key to loosen the side-locating bolt on the handlebar stem. Do not fully remove it—just release the tension.
- Gently lift the handlebar and rotate it to the desired angle (e.g., forward for aggressive riding, upward for comfort).
- Tighten the bolt with a torque wrench to 22-25 Nm.
Handlebar Angle Adjustment:
- Use a 4mm Allen key to loosen the four stem cap screws (don't fully remove them).
- Grip the handlebar and gently pivot it upward or downward to set the desired vertical angle.
- With a 4mm Allen key, tighten the four stem cap screws in an X-pattern to a torque of 6-8 Nm.
Comfort Adjustment
The final step is to dial in the settings for a perfect, comfortable fit.
Seat Height Adjustment:
- Open the seatpost quick release lever.
- Adjust the seatpost height by sliding it up or down to a height appropriate for your leg length.
-
WARNING: Do not extend the seatpost beyond the minimum insertion marking etched onto it. Overextending it can cause it to break or come off, putting you at very high risk of serious injury or death.
Seat Angle Adjustment:
- Use a 5mm Allen wrench to loosen the seat adjustment bolt on the clamp positioned directly underneath the seat.
- Move the seat backward or forward and tilt it to adjust the angle. A position horizontal to flat ground is desirable for most riders.
- While holding the seat in position, use a 5mm Allen key to tighten the bolt securely to the recommended torque value of 8Nm.
Front Fork Adjustment:
- To lock the suspension: Turn the adjustment knob clockwise until the suspension locks up. This is ideal for smooth, paved roads.
- To soften the suspension: Turn the adjustment knob counter-clockwise to decrease compression damping.
-
To adjust preload: Turn the preload adjustment knob counter-clockwise until it stops. This is the minimum preload, or the softest setting.
Assist System Operation: Your Control Center
Once your bike is assembled, it's time to master its brain: the Himiway Assist System. Understanding the display and controls will allow you to customize your ride for power, range, and comfort.
Understanding Your Display
The display is your dashboard, providing real-time information about your ride. Here's what you're looking at:
- 01: Battery Level: Shows your remaining charge.
- 02: Speed: Your current speed.
- 03: Speed Unit: Miles per hour (mile/h) or kilometers per hour.
- 04: Speed Bar: A visual representation of your speed.
- 05: Riding Data: Shows trip distance (TRIP) or total distance (ODO).
- 06: Power Bar: Indicates how much power the motor is currently using.
- 07: Assistant Level: The current level of pedal assistance (e.g., ECO, SPORT).
- 08: Light: Shows if your headlight is on.
- 09: Error Code: Displays a code if the system detects a fault.
- 10: Turn Signal: Indicates if the left or right turn signal is active.
Basic Button Controls
Your control pad on the left handlebar is how you interact with the assist system.
Accessing the Settings Menu
To unlock the full potential of your e-bike, you'll need to enter the settings menu.
- After powering on, long press the 'M' button for 2 seconds to bring up the password interface.
- Enter the password 0510. Use the 'Plus' or 'Minus' buttons to select numbers and a short press of the 'M' button to move to the next digit.
- After entering the password, a short press of the 'M' button will grant you access to the full settings menu.
Key Settings to Customize Your Ride
Inside the settings menu, you can fine-tune your bike's performance.
Tuning Your Assist Modes (Torque & Ratio)
In the Assist Mode Setting menu, you can adjust the Assist Torque and Assist Ratio for each of the five levels (ECO+, ECO, TOUR, SPORT, TURBO). This allows you to decide how much power the motor delivers at each level, tailoring the feel of the ride to your preference, from gentle assistance to powerful acceleration.
Switching Sensors (Torque vs. Cadence)
Under Assist Mode Setting > Assist Sensor Switch, you can choose between Torque and Cadence assist modes. Torque mode provides power proportional to how hard you pedal, offering a more natural riding feel. Cadence mode provides a set amount of power as long as you are pedaling, regardless of effort.
Note: The system offers many more detailed settings. For a complete guide to every function, please get manual pdf the"HMW ASSIST SYSTEM 1.0 USER MANUAL".

Installation Verification: Your Final Safety Check
Think of this as a pre-flight checklist for your bike. It's a critical final step before your first ride.
Review this safety checklist:
- Brakes: Test both front and rear brakes for proper function. Make sure the control levers are tightly secured to the handlebars.
- Wheels and Tires: Check that all wheel spokes are tight and not broken. Ensure the rims run true and have no obvious wobbles or kinks. If riding feels imbalanced or the front wheel makes noise, it likely means the bolts were not completely tightened or didn't align horizontally.
- Cranks and Pedals: Ensure the pedals are securely tightened to the cranks and that the cranks are securely tightened and not bent.
- Battery Pack: Ensure the battery is charged before use and locked securely to the frame.
