The range of your Whizz e-bike is the distance the bike will travel on a single full charge of the onboard battery pack. The range values are estimates based on expected usage characteristics. Some factors that may affect the range include changes in elevation, speed, payload, and acceleration, number of starts and stops and ambient air temperatures. Tire pressure and terrain are also important variables to consider.
To extend the range and battery life, please follow several rules:
When the input and output plugs of the charger are connected properly, and the battery is not fully charged, the red charging indicator light should illuminate, showing that the battery is charging. The time that the battery takes to fully charge the battery is dependent on various factors including distance traveled, riding characteristics, terrain, payload, and battery age.
If your battery does not seem to be charging properly or it takes longer to charge than expected, immediately contact our support team for further guidance.
To ensure safe riding conditions you must ensure your bike is properly maintained. You should follow these basic guidelines and visit our service center on a regular basis to ensure your bike is safe for use.
1. Properly maintain batteries by keeping them fully charged when not in use.
2. Never immerse the bike or its parts under water as the electrical system can be damaged.
3. Periodically check wiring and connectors to ensure there is no damage and the connectors are secure.
4. Clean, wipe the frame with a damp cloth soaked in a mild non-corrosive detergent mixture. Dry with a cloth.
5. Store the e-bike under shelter; avoid leaving it in the rain or exposed to corrosive materials. If exposed to rain, dry your bicycle afterwards and apply anti-rust treatment to chain and other unpainted steel surfaces.
6. Riding on the beach or in coastal areas exposes your bicycle to salt which is very corrosive. Wash your bicycle
frequently and wipe or spray all unpainted parts with anti-rust treatment. Damage from corrosion is not covered under subscription fee so special care should be given to avoid penalties for damage caused by the use in coastal areas or areas with salty air or water.
Please follow these basic parking, storage, and transportation tips.
