I too bought one of the Cyclamatic Power Pro e-bikes this week. I've been aware of e-bikes for a while but thought I'd wait some years until the technology advances enough to make them affordable to someone on a limited budget like me. But when I saw the price of these bikes I thought I might as well take a bit of a gamble.
It arrived with the front tire inflated but the back one as flat as a pancake, which was a bit worrying. The seller said I should just go ahead and pump it up, and if it does go back down then to take it to the local bike shop and they'd refund the cost of replacing the tube. I'm hopeless enough with normal bike tires, and I've heard that the back wheel is especially difficult to do on this bike(?).
My first impressions are positive. It's certainly more powerful than I was expecting. I took it on a route that would usually leave me barely able to walk if tackled with my normal bike, but with the Cyclamatic it took much less time and a fraction of the effort. The only thing I'm still learning is how to use the right gears with in assist mode, but I'll figure that out soon enough. What I especially like about the experience is that it allows you to set your own pace, so you can still get a decent amount of exercise without exhausting yourself. It's also a lot of fun!
On the negative side - as others have said on this forum - who knows what will happen in a week, a month or more, or how difficult it will be to replace the battery or anything else come to that. Ah well, we'll see.
