Hi there!! I'm in cold wet England!! Have just finished fitting the 70cc unit to my ancient Raleigh mountain bike (That was rotting away in one of my sheds!!) The whole transition went incredibly smoothly and the bike goes like a rocket. The only trouble being, that here in England we have so many stupid "nanny state" laws that, in theory, it's illegal to use it on the roads! Fortunately I live in the depths of Suffolk, in a small village where we seldom see a cop car, so I've been out enjoing myself.......albeit with one eye constantly in the mirror! Have even managed to achieve 40mph, but then I do only weigh 68Kg!! Not bad for an aged 57year old hippie!! On the downside, I constantly seem to destroy inner tubes, the last time in the dark, miles away from home & my wife away for the weekend.......what a time for two flats!! and what a time for a VERY long walk home. What I really need is a two cable brake lever. I can't get one in this country, and I did e-mail Spookytooth for a price to ship one to me, but they never replied. I think these motorised bike things are the best thing since sliced bread......I LOVE mine!! Be lovely to hear from some of you "Yanks", you seem to have so much more fun than us!!
