3. Setup and Assembly
The HITWAY BK7 electric bike comes largely pre-assembled. Final assembly typically involves attaching the front wheel, handlebars, pedals, seat, and making minor adjustments.
3.1 Unboxing and Initial Inspection
Carefully remove the bike and all components from the packaging. Inspect for any visible damage during transit. Keep all packaging materials until assembly is complete and you are satisfied with the product.
3.2 Component Assembly
- Front Wheel Installation: Attach the front wheel, ensuring the disc brake rotor aligns correctly with the caliper. Secure the quick-release skewer or axle nuts firmly.
- Handlebar Attachment: Insert the handlebar stem into the fork tube and tighten the stem bolts. Ensure the handlebars are straight and secure.
- Pedal Installation: Identify the left (L) and right (R) pedals. The left pedal tightens counter-clockwise, and the right pedal tightens clockwise. Thread them carefully into the crank arms and tighten securely with a wrench.
- Seat Post and Saddle: Insert the seat post into the frame and adjust the saddle height to a comfortable riding position. Tighten the quick-release lever or bolt.
- Battery Installation: The 48V/7.5Ah lithium battery is integrated into the frame. Ensure it is securely locked in place.

4.3 Riding Modes
The HITWAY BK7 offers three distinct riding modes:
- Electric Mode: Provides full motor power without pedaling. Ideal for effortless cruising.

- Manual (ManPower) Mode: The bike operates like a traditional bicycle, with no motor assistance.
4.4 Gear Shifting
The bike is equipped with a 21-speed Shimano transmission system. Use the shifters on the handlebars to change gears according to terrain and desired speed. Shift smoothly to avoid strain on the drivetrain.
