Hi Ive had a Viking ego 24 for 3 months and the wiring has come out of the controller and all power gone. tesco say they will full refund. But what now? I was thinking i'd go for something a bit lighter with less weight on the back. Has anyone got/had a woosh zephyr? thats about my limit for price . i got the viking instead of the £400 hopper as they'd ran out still for £400 but i dont know whether its best to just fix it or try something else. Any advice would be fab thanks! or a recommendation of a folding elcetric bike for less than £600? thanks
