Hi all. I got my first electric bike about 5 months ago. I got myself a wisper city works 905Ise, and I think its great. I used the forum when I was choosing my bike, but now I could do with some help and advice please. My throttle has stopped working for no apparent reason, and I really miss it when Im doing a hill start. I would really appreciate any advice as to what it could be and how to fix it. Thanks Di
