The Miller SE ebike is an electric bicycle designed for urban use on flat, paved roads, offering a blend of safety, performance, and ease of maintenance. It is not intended for racing, jumps, hops, wheelies, off-road riding, or commercial use. The manufacturer, Enki Cycles, LLC, emphasizes adherence to safety guidelines and proper maintenance to ensure a long and enjoyable riding experience.
Function Description:
The Miller SE ebike is a pedal-assist electric bicycle equipped with a hub motor that provides assistance as the rider pedals. The system senses crank rotations and pedal pressure, activating the motor to propel the bike further. When pedaling stops, the motor power is cut off. The amount of motor power and corresponding top speed are determined by the selected Pedal Assist System (PAS) level. The bike features a display and an integrated 3-button keypad (Power, Mode, Up, Down) on the left handlebar grip to control the ebike power system, navigate through trip and system information, and customize the riding experience. The display shows real-time speed, distance traveled, time, average speed, maximum speed, odometer, and battery charge level. A "Walk mode" can be activated by pressing the Down button for 3 seconds, allowing the ebike to travel at a constant speed of 6km/h to assist pushing.

Usage Features:
- Handlebar Controls: The left grip houses the display and a 3-button keypad for power, mode selection, and adjusting pedal assist levels (PAS 0-5). Brake lever positioning varies by region (e.g., USA: left for front, right for rear; Europe/Australia/UK: left for front, right for rear).
- Pedal Assist (PAS): Offers 5 programmed levels of assistance, with 0 providing no assistance and 5 providing the most. Riders can increase or decrease the PAS level using the Up and Down buttons.
- Walk Mode: Activates a constant speed of 6km/h to assist pushing the bike, not for riding.
- Seat Adjustment: The seat height can be adjusted by loosening/tightening the seat post clamp. The seat angle and fore/aft position can also be adjusted by loosening/tightening the rail clamp bolts.
- Battery Charging: The battery is charged via a port on the downtube. The charger indicator light turns red during charging and green when full. It is recommended to fully cycle the battery periodically and store it at 40%-50% charge to maximize life.
- Tire Inflation: Uses a Presta valve. Recommended pressure is 50-85 PSI.
- Drive System: Features a Gates carbon belt drive system. Belt tension and wheel alignment are adjusted by manipulating floating black dropouts at the rear wheel axle.
- Brakes: Equipped with front and rear hydraulic disc brakes. Caliper positioning adjustments and removal are accessed via bolts on the calipers.
Maintenance Features:
- Pre-Ride Safety Checklist: Before each ride, check tires for inflation and wear, brakes for proper adjustment and pad condition, saddle for secure positioning, steering for alignment, belt for wear, cranks and pedals for security, frame for damage, forks for smooth operation, motor for unusual sounds/smells, and battery for charge.
- Regular Servicing: Important for optimal condition. If lacking mechanical expertise, consult a certified bicycle mechanic for brakes, drive system, and electronics.
- Cleaning: Regularly clean the ebike with a damp cloth to remove dirt and debris, avoiding high-pressure water. Lubricate joints, connections, and metallic surfaces to prevent rust and corrosion.
- Battery Care: Periodically cycle the battery from full to empty and then fully charge it. Store batteries at 40%-50% charge. Avoid extreme temperatures during operation and charging.
- Drive System Adjustment: The manual provides instructions for adjusting belt tension and wheel alignment, but advises consulting a qualified bicycle mechanic if inexperienced.
- Brake Maintenance: Regularly check brake pads, adjustment, lever pull, and hydraulic fluid condition.
- Torque Settings: A table of standard torque values (Nm) is provided for various components, including handlebar bolts, handlebar expander, handlebar stem and fork clamp bolt, saddle, seat post clamp, front wheel, and rear wheel.
- Storage: Switch off the bike when pushing. Use a reputable lock and fold the bike for security. Store in a dry location to minimize corrosion and waterlogging. Ensure any racks used for transport can support the ebike's weight.
Warnings and Important Notes:
- Risk of Injury: Always read and follow all instructions and warnings in the user manual to minimize the risk of death or serious injury.
- Adult Supervision: The Miller SE ebike is not recommended for children under 14. Adult supervision is required for riders 14 and older.
- Helmet Use: Advised to minimize brain injury risk.
- Warranty: Lifetime warranty for the frame, 90-day warranty for forks, handlebars, head stems, drive system, kickstand, and electronics. Warranty is voided by misuse, neglect, commercial use, alterations, improper assembly, wear and tear, operator error, water damage, extreme riding, stunt riding, or improper maintenance. Any modifications to electronics void all warranty claims.
- Component Failure: Extending the seat post past the minimum insertion point or the seat post clamp outside the marked range can lead to component failure and serious injury.
- Motor Cable Connection: Do not ride the ebike without the motor cables properly connected to avoid damage.
- Tire Pressure: Do not over-inflate past 85PSI or under-inflate below 50PSI to avoid tire damage and serious injury.
- Battery State: Do not leave the battery in an empty state of charge to prevent permanent damage.
- Charging: Only use the included charger. Turn off power immediately and contact support if anything unusual occurs during charging.
- Brakes: Brake levers are not equipped with motor inhibitors. For safety, switch PAS to 0 or power off if not intending to use electric propulsion.
- Pedal Installation: Pay careful attention to the angle and tightening force to avoid damaging the crank arm. Read pedal labels carefully to avoid incorrect installation.
