Operation Instruction

NOTICE: Do not perform any steps in the Operation section until you have read the entire manual, as it contains important safety details.

Read and understand all sections of this manual before operating the bike for the first time. Important safety warnings must be followed to prevent dangerous situations, accidents, damage to the bike, property, injury, or death.

Users must follow instructions and warnings for safety. Do not attempt to operate the bike until you have adequate knowledge of its control and operation. Damage from failing to follow instructions is not covered under warranty and could result in serious injury or death. Contact Aventon Bikes with any questions about assembly or operation.

Become accustomed to the bike's power control system before operating. The pedal assistance feature is powerful; research and understand its operation before first use. Failure to familiarize yourself and practice the power system operation can lead to damage, serious injury, or death.

Driving Range

The driving range is the distance the bike travels on a single full charge. Range values are estimates based on expected usage characteristics. Factors affecting range include elevation, speed, payload, acceleration, starts/stops, ambient temperature, tire pressure, and terrain.

It is suggested to select a lower assistance level when first using the bike to learn its behavior and routes. Adjust riding characteristics as you become familiar with range requirements and bike capabilities.

The following table provides general range estimates based on various factors. It helps owners understand factors contributing to decreased range, but Aventon Bikes makes no claims about individual user experiences.

User Maintenance and Service Instructions

Basic Bike Care

If you lack the experience, skill, or tools for maintenance, Aventon Bikes strongly recommends a certified, reputable bike mechanic for maintenance, tuning, and safety checks.

Recommended Service Intervals

Regular inspection and maintenance ensure proper function and reduce wear. Intervals are guidelines; real-world wear varies. Follow the table for recommended service.

Pre-Ride Safety Checklist

Notice: Before every ride, and after every 25-45 miles (40-72 km), follow the pre-ride safety checklist.

Tire Information

Your cables, spokes, and chain will stretch after an initial break-in period of 50-100mi (80-160km), and bolted connections can loosen. Always have a certified, reputable bike mechanic perform a tune-up on your Pace 500.3 after your initial break-in period (depending on riding conditions). Regular inspections and tune-ups are important for ensuring your bike remains safe and fun to ride.

The PACE 500.3 uses 27.5" x 2.1" rubber tires with inner tubes, designed for durability and safety. Check tires for proper inflation and condition before each use. Proper inflation, care, and timely replacement maintain operational characteristics and prevent unsafe conditions.

Aventon Bikes recommends 30-50 PSI (2.0-3.5 BAR) for the stock tires. Always stay within the manufacturer's recommended air pressure range on the tire sidewall.

[!] It is critical that proper air pressure is maintained. DO NOT underinflate or overinflate. Low pressure can lead to loss of control; overinflated tires may explode. Failure to maintain correct pressure may result in tire/wheel failure.

Inflate tires from a regulated air source with a gauge. Unregulated sources may overinflate. Tires can get flats from punctures, pinches, impact, etc. When tire wear is evident or a flat occurs, replace tires/tubes before operating the bike to prevent injury or damage.

When changing a tire or tube, ensure all air pressure is removed from the inner tube first to prevent serious injury.

Using aftermarket tires or inner tubes not provided by Aventon Bikes may void your warranty, create unsafe conditions, or damage your bike. Ensure replacement tires have sufficient reflective sidewall striping if required by law.

For tire/tube replacement procedures or inflation questions, contact Aventon Bikes Product Support: https://support.aventon.com/contact-us or call 1-866-300-3311.

Derailleur

On the right handlebar, next to the brake lever, are two levers for 8-1 gears. These are derailleur levers. Pressing them moves the chain to different gears to change your riding experience.

Trouble Shooting

Error Detection

The bike has an error detection system. If a fault occurs, an error code may display. The following are common codes. If an error code is displayed, cease operation and contact Aventon Bikes immediately.

Additional Information on Wear

Pace 500.3 components experience higher wear than non-powered bikes due to higher average speeds and weight. This wear is not a defect and not covered by warranty. Affected components include tires, brake pads/rotors, spokes, wheels, and battery.

[!] Surpassed component lifespan can cause unexpected function loss, leading to serious injury or death. Pay attention to cracks, scratches, or color/operation changes. Worn components should be replaced immediately. Consult a mechanic if unfamiliar with maintenance.
