City Electric Bike Assembly Guide

Welcome to Your City Electric Bike Assembly Guide

Congratulations on your new city electric bike! This step-by-step guide will help you safely assemble your bike at home. City e-bikes are designed for comfort and ease of use, and assembly is straightforward when you follow these instructions.

Tools You'll Need

• 15mm wrench or adjustable wrench
• 4mm, 5mm, and 6mm Allen keys (hex wrenches)
• Phillips head screwdriver
• Tire pump with pressure gauge
• Bike grease (optional but recommended)

Before You Start

Important: Carefully unpack all components and verify you have all parts listed in your packing list. Keep all packaging materials until assembly is complete.

Step 1: Attach the Front Wheel

1. Remove the front wheel from packaging and inspect the tire
2. Remove the protective spacer from the front fork
3. Slide the wheel axle into the fork dropouts
4. If your bike has disc brakes, ensure the rotor aligns with the brake caliper
5. Tighten the quick-release lever or axle nuts securely
6. Spin the wheel to ensure it rotates freely

Step 2: Install the Handlebars

1. Remove the stem cap and loosen the stem bolts
2. Insert the handlebars into the stem
3. Align the handlebars perpendicular to the front wheel
4. Tighten the stem bolts evenly in a cross pattern
5. Adjust handlebar angle for comfortable upright riding position
6. Ensure handlebars are secure but not overtightened

Step 3: Attach the Pedals

1. Identify left and right pedals (marked with "L" and "R")
2. Apply a small amount of grease to the pedal threads
3. Right pedal: Thread clockwise into the right crank arm
4. Left pedal: Thread counter-clockwise into the left crank arm
5. Tighten securely with a 15mm wrench

Step 4: Install the Seat and Seatpost

1. Insert the seatpost into the seat tube
2. Adjust to a height where your leg is slightly bent when the pedal is at the lowest position
3. Ensure the minimum insertion line is not visible
4. Align the seat with the frame
5. Tighten the seatpost clamp securely
6. Adjust seat angle for comfort (typically level or slightly nose-down)

Step 5: Check and Inflate Tires

1. Check that tires are properly seated on the rims
2. Locate the recommended PSI range on the tire sidewall
3. City bike tires typically require 40-65 PSI
4. Inflate to the middle of the recommended range for best comfort and performance
5. Check both valve stems are secure

Step 6: Battery Installation and Charging

1. Locate the battery compartment (usually on the frame or rear rack)
2. Insert the battery and ensure it clicks securely into place
3. Check that the battery key locks properly
4. Charge the battery fully before your first ride (typically 4-6 hours)
5. Familiarize yourself with the battery removal process

Step 7: Display and Controls Setup

1. Ensure the display unit is securely mounted on the handlebars
2. Check that all cables are properly connected
3. Turn on the display and verify it powers up
4. Familiarize yourself with the control buttons and settings
5. Test the pedal assist levels and throttle (if equipped)

Step 8: Brake Adjustment and Safety Check

1. Squeeze both brake levers to ensure they engage properly
2. Check that brake pads are not rubbing when wheels spin
3. Adjust brake lever reach if needed for comfortable hand position
4. Test that brakes stop the wheels completely
5. Ensure brake cables are properly secured

Step 9: Lights and Accessories

1. Install front and rear lights if not pre-installed
2. Connect lights to the battery system (if integrated)
3. Test that all lights function properly
4. Attach any included accessories (fenders, rack, kickstand)

Step 10: Final Safety Inspection

Before your first ride, check the following:

• All bolts and quick-releases are tight
• Wheels spin freely without wobbling
• Brakes engage smoothly and stop the wheels
• Handlebars are secure and aligned
• Seat is at proper height and secure
• Pedals are tight and rotate smoothly
• Battery is charged and securely locked
• Display powers on and functions correctly
• Lights work properly
• Chain is properly lubricated

First Ride Tips

• Start in a low pedal assist level to get familiar with the power
• Practice braking in a safe area – e-bikes are heavier than regular bikes
• Get comfortable with the throttle (if equipped) before using in traffic
• Adjust seat height if needed after your first short ride

Break-In Period

After your first few rides, recheck all bolts and connections. Cables may stretch and components may settle, requiring minor adjustments. This is completely normal.

Battery Care Tips

• Charge the battery after each ride to maintain optimal performance
• Store the battery indoors in moderate temperatures
• Don't let the battery fully discharge regularly
• Remove the battery if storing the bike for extended periods
