I bought 9 of them for a bike hire business. Mine had the original Impulse motor. I had motors replaced on 4 or 5 of them. I have now closed the business and sold most of my bikes.They are great bikes but I'm not sure I'd buy one now that there are a number of similar alternatives.
I currently like the Winora Radius, this uses the Yamaha motor. KTM and Reise&Muller also have similar bikes with Bosch motors.
Great site, I've been looking for a eBike forum to obtain & share information on this relatively new technology, and I'm so glad I found you have had the foresight to start this up. Keep up the great work
Thank you for adding me to your forum..... I have, I suspect some very newbie questions to ask. You've probably heard them all before so I'll trawl the previous posts first
