I haven't been able to read the whole thread yet, but I would still like to offer something up.
I am new to eBiking. I bought my bike in April. I am Loving it, and, I am Loving my bike.
I have essentially a
Lectric clone, with a couple of upgrades. [battery, regen feature]
I had a very good experience with the dealer I purchased through.
However, a couple of months later, and some reflection, and I have to say - I regret not buying from the bigger names.
This eBike market is in its infancy, constantly evolving. A bike running today may Not have parts available once it is out of warranty.
Yet, a bigger name like Lectric is rapidly gaining a great rep for service. A few years from now, I still expect Lectric customers to
be able to get replacement parts.
If you are super handy and build stuff, maybe all of this is moot. But, if you are not that handy and/or just want a turnkey bike without hassle, you might want to seriously consider purchasing only from a big name, and if you are in the U.S., you will want that big name selling, distributing, and supporting all from the U.S.
Do research on both the manufacturer of your bike and the person selling it to you. There are Many companies out there who are essentially 1 or 2 people - simply rebadging bikes from China. Those people have very little leverage with the manufacturer when things go wrong, and they have just about no capacity, nor capital, to supply you with parts.
For what I need, if I buy another bike, it will be a Lectric. Simply because I Know they are committed to service. And they have the capital to deliver it.
Many of the eBikes on the market today are great - while they work. When things go wrong, and - things Will go wrong - you need to know that someone will help you - quickly - without losing a whole season waiting for a replacement part.
Do your homework.
