Remember all bikes bought from us have:
2 years warranty on the electrics including the battery
at least 12 months on any other non consumable parts.
The key thing to remember with electric bikes is that the battery needs to be charged regularly (at least every two months) even when not in use. Never leave it discharged for a prolonged period. In the winter months bring the battery indoors and charge at room temperature rather than trying to charge in a cold garage.
