Important Notes for Your E-Bike
Real-world range varies based on rider weight, terrain, tyre pressure, speed, wind, and riding style. The estimated figures are 25–28 miles in electric-only mode and 28–43 miles with pedal assist. Charging from empty to full takes 5–6 hours using the included original charger; third-party chargers may affect charging time and battery safety.
Your bike arrives partially assembled and requires simple setup of the handlebars, pedals, front wheel, and saddle. Basic tools are included, and you should check all bolts and tyre pressure before your first ride. Watch the assembly video here: https://www.youtube.com/watch?v=GyzoGWG2gsQ
To prolong battery life, avoid fully draining it before recharging and store it in a cool, dry place away from heat sources. If storing for extended periods, keep the battery at around 50–60% charge. Before every ride, check brakes, lights, and tyre pressure, and follow UK road regulations for e-bikes.
This e-bike is designed for dry and lightly damp conditions; avoid deep water or heavy rain to protect electrical components. Schedule a service after the first 62 miles (checking spokes, brakes, and gears), then every 310 miles or 6 months. Maximum load is 330 lbs (rider plus luggage); exceeding this may compromise frame durability and safety.
