I have had a Pro Connect since last July.
Yes I had to wait for it because it was advertised months before it arrived in this country but it was worth the wait. My previous ebike was the 'classic ebike' the Giant Lafree Twist ST, and the Pro Connect is better in many ways i.e. great looks, much better easy maintenance brakes, less weight, range better.
The ride does need to be improved by adding a sprung seat post which is easy enough to do and makes a much better ride.
I changed the rear sprocket to a 16T which means my legs don't have to go like the clappers when going at speed down a hill.
I had one of the dodgy batteries but 50 Cycles replaced it immediately and they have been quick to reply to my emails about the occassional question I had about the bike.
The only gripe I have now is the latest price. I was considering getting a second bike as a back-up but may have to rethink unless they put a special offer on with a good discount
