Ok guys, I just got hired by a company that sells foldable e-bikes. During my initial salary negotiations, I was offered one of their e-bikes in return for testing it out to work one day and after a couple of weeks present my overall experience with the bike to my boss and the executive vice president. Obviously, I didn't turn down a free e-bike. The only problem is that I have no experience with e-bikes and I haven't owned a bike since I was in my early teens - I am now close to 30 and starting to regret taking the bike

Could anyone tell me what the standards of a current e-bike are?
This one offers a battery life of +15 hours in charge, combined with a 250W 24V brushless (not sure what that means) hub motor. Is that good? As far as I've heard, local retailers are doing quite well selling the thing but it doesn't really help me understanding what I am looking for. Other specifications included an LCD screen to measure speed and I was told it's wires and connector are water resistant. My goal is to know as much as I possibly can before that presentation.

Here's my experience so far:

I tried it around the block the other day, it felt strange in a good way to say the least. People were totally checking me out, probably because the bike has this sleek finish but also because they could see that I looked uncertain riding it It has some kind of pedal assist system so I don't really need to pedal that much at all. That was cool but I found myself wanting to pedal more. Is that something e-bikes have in general? Is it suppose to be silent by the way?

Listen guys, any info at all is appreciated my presentation is in 2 weeks but I just wanna try to be proactive so I don't make a fool out of myself. Oh, the bike is called "Db0 3.0" maybe some of you own/sell or have heard about it?
