I was hoping some of you more tech savvy people may be able to help. My wisper 806 torque I think 2016 model has died! I am not a regular user but a few weeks ago took it out for a spin. When I switched on the power absolutely nothing. I reseated the battery a few times but still nothing. After an hour of fiddling I went back home disappointed. Yesterday I tried again this time it did power up and after a 5 mile ride stopped and had break. Switched of the power but when I returned nothing, really frustrated and after several attempts had to cycle back on raw leg power which in my condition wasn't good. The battery has been very well looked after and about just over 2 years old. Always charged and kept in dry conditions. I have checked the wiring as far as I am able but still nothing. I thought their are only 3 main components excluding the motor. The battery, the controller, and wiring.I have removed the battery many times and refitted and its holding its charge so unless a fault has internally developed Im not sure. I have only had this bike 4 months and I have contacted wisper but was wondering if you guys might have few ideas. So downhearted very few pleasures left in life and its very dear to me. anything please?
