This document is the owner's manual for the Yotobike Leopard-Fat Tires Electric Mountain Bike. It provides details on the product's operation, maintenance, and helpful tips for owners to ensure safe use, reduce damage, and prevent accidents.
Function Description
The Yotobike Leopard is an electric mountain bike designed for various riding conditions, including off-road. It features pedal-assist modes, a throttle-only mode, and a pedal-only mode, offering flexibility in how the rider chooses to operate the bike. The pedal-assist system engages the motor to aid pedaling, with five adjustable levels (1-5) to suit different preferences and riding intensities. The throttle-only mode allows the rider to propel the bike without pedaling, similar to a motorcycle or scooter, and can reach speeds of up to 25 miles per hour. The pedal-only mode functions like a traditional bicycle, without motor assistance, useful for intensive resistance training or when the battery is depleted. The bike is equipped with a C900E-USB display that provides various functions and indicators, including electric quantity, backlight, speed, power output, riding mileage (Trip and ODO), ride time, and riding mode selection (POWER, NORMAL, ECO).

Usage Features
- Assembly: The manual provides detailed instructions for assembling the bike, including handlebar installation, front wheel installation, headlight installation, pedal installation, and seat adjustment. It emphasizes removing the battery during assembly to reduce weight and prevent damage.
- Safety Precautions: Users are advised to read the manual thoroughly, understand all safety notes and warnings, and follow a safety checklist before and during rides. Important safety points include wearing an approved helmet, being aware of sudden acceleration in pedal assist mode, ensuring the front wheel quick-release lever is securely closed, and exercising caution during off-road riding.
- Display and Settings: The C900E-USB display allows users to monitor electric quantity, speed, power, and mileage. It also enables selection of riding modes (POWER, NORMAL, ECO) and adjustment of various settings such as backlight brightness, speed limit, wheel size, units (KM/H or MPH), and assist levels (3, 5, 6, or 9). The display also shows error codes for troubleshooting.
- Battery Charging: The manual outlines procedures for both on-bike and off-bike charging. It recommends checking the battery power indicator, inserting the charger's DC plug into the battery charging socket, and then connecting the power plug to the power socket. Users are warned against pulling the brake lever without the red pad or brake disc inserted to prevent damage to the hydraulic brake caliper.
- Riding Modes:
- Pedal-assist: Engages the motor to assist pedaling, with five levels of assistance. Higher levels (L4/5) are for faster riding with minimum effort, while lower levels (L1/2) are suitable for leisurely exercise or stress relief.
- Throttle-only: Allows the bike to be propelled solely by the motor, reaching speeds up to 25 mph.
- Pedal-only: Functions as a regular bike without motor assistance, ideal for resistance training or when the battery is depleted.
- Riding Limitations: To prevent overheating or damage to the mid-motor, riders should avoid hills steeper than 15% grade, use pedals to assist the motor when climbing or accelerating, and avoid sudden starts and stops, preferring moderate acceleration.
- Parking & Transport: Users are advised to turn off power and lights, remove the key, and secure the battery when parking. The bike is water-resistant (PX4), but parking outdoors in cold or inclement weather for extended periods is not recommended. For transport on a rack, removing the battery is suggested to reduce weight.
- Carrying Loads: The bike has a total payload capacity of 70 lbs. Tips for safe cargo operation include loading cargo as low as possible, securing loads properly, planning routes considering cargo weight, and practicing with cargo in a safe area. It also advises applying the rear brake first, followed by the front, to avoid loss of control, especially with cargo. The kickstand is not designed to hold the bike upright with cargo alone.
Maintenance Features
- Safety Checklist: A comprehensive checklist covers brakes (function, pad wear, cable lubrication, lever security), wheels and tires (inflation, wear, true rims, spoke tightness, balance), chain (oiling, cleanliness), cranks and pedals (tightness, straightness), derailleurs (adjustment, function, cable lubrication), motor drive (smooth spinning, secure cables, secure axle bolts), and battery pack (charge, damage, security).
