The following text containing a comprehensive description will provide you with information on all aspects and details (including installation, setting up and general use of the display) regarding the use of our display.
- Page 3 Factors influencing the electric bicycle range 1. Rolling resistance of the tyres. Leader Fox e-bikes are fittet with tyres with low rolling resistance and increased resistance to puncture. It is also important that the tyres are inflated properly. Therefor, if the tyres of your electric bicycle are underinflated, the range will decrease.
- Page 4 Battery Riding safety: While riding, pay only as much attention to the bicycle settings and display as not to jeopardize your safety. Before riding, check that wheels have been securely fitted in the frame and fork, since their incorrect installation can cause serious injury. When riding the electric bicycle, you should be fully familiar with its behaviour and control, otherwise it could result in serious injury.
- Page 5 Description Battery charging and maintenance: Charge the battery in a dry enviroment to avoid short-circuit damage. Charge the battery to at least 60% of the capacity once every 3 months even when the bicycle is not used. Do not cover the battery or the charger. Do not leave the battery constantly connected to the power source.
- Page 6 If you feel your total battery capacity has dropped, it could be caused by charging or operation in suboptimal climatic conditions. Carry out 3 full charging cycles. Fully discharge the battery while riding and then charge to its full capacity at room temperature. If the charge indicator shows that the battery is discharged, there is still a minimum voltage level in it which protects it against damage but is not enough to power the electric bicycle.
