I bought a Wisper 905se 18 months ago did 1500 miles and have loved it, ultra reliable and easy to maintain, about a month ago I bought a Carrera Crossfuse and have done 100 miles on it, I was very impressed with the Bosch Activeline plus motor and the quality of the bike. Now comes the dilemma 10 days ago I suffered a heart attack and had to have 4 stents, back home now and slowly recovering (bless the NHS) obviously I cant ride at the moment and it is going to be a slowish recovery. Would I be better keeping the Wisper where I can ghost pedal and also use a full throttle or the Carrera which is slightly lighter and more nimble but requires more pressure on the pedals?
