Hi Im new to electric bikes (lung problems at the age of 71 stopped me riding my normal bike) so I bought myself a Powacycle Windsor. I like this bike very much apart for the fact it keeps cutting out at the most inoportune moments. Did I buy wrong or is this normal? I have cleaned the battery teminals in the battery case and on the bike all to no avail. I'm ignorant about electronics so if anyone can help I'll be forever in your debt. The dealer I bought the bike from is 70+ miles from home so a return visit is not on. I live in Bucks and made a spur of the moment buy so hope I will not regret it. I must say I enjoy this site enormously and wish you all well. Thanks Gangang
