I have a battery assist bike and love it. The 'assist' bit only works when you are pedalling but acts just like someone giving you a very gentle push. You get the exercise but it is not so 'knackering' so can go further - or at least as far as the battery allows !! (about 20 miles with my bike).

bought myself a little water bracket/pump and have sent off for a BIG bum saddle
n biscuits and oxygen!
