Hello. That one is not a hub motor, its a mid drive. It also does not have in integrated battery, its removable. Its has a warranty longer that one year website also mentions mentions a lifetime warranty. Meridia is also a brand of ebikes that i couldn't find too many reviews on, so i'm not sure if its any good.

I'm new to this, I have been watching some of his videos, I can see that he is very pro conversion, but I'm not too sure about it because when about conversions at my local bike shop, but they said that they don't do it because they don't believe that converting a normal bike to a ebike would be good. They sited reasons like how normal bike frames aren't designed to be an ebike, They won't be able to handle torque as well, the frame is usually less sturdy. They also mentioned that since the body of the bike is usually round, mounting the battery is going to be more difficult and its likely to loosen over time. (looks like the bike used in the step by step bafang installation guide is an exception) Additionally its not that good to install a mid drive on a traditional bike as they will only have 1 mounting point so over time they are prone to start wobbling. So overall higher maintenance and lower quality.

I'm not sure how qualified what they are saying is, but what do you think?

again, avoid premade ebikes period. forget what local bike shops say, they dont do any custom ebike work and therefore know little about it, in my experience. some guy told me 'oh thats going to change the handling on the full suspension bike, not recommended at all blah blah' . what did he know, hes never seen or worked on a custom ebike. bafang kit didnt change the handling or suspension performance at all, it made the bike a total beast without me having to huff and puff with the effort of a regular bike. that said, you DO want a strong, solid, aluminum or steel frame, not a cheap one. and overall with a mid drive kit its less maintenance and higher quality than any premade ebike, or hub motor setup.

Thanks. They do say that they have done some custom ebike work but the amount of work it takes to do properly make it not generally worth worth it. Mentioned something about it taking 10 hours of work to convert a cargo bike, but seeing how johnny nerd out takes less than 2 hours to do so on stream you are probably correct about their lack of experience. I'm probably mis representing what they say about disadvantages on converting a traditional bike but you have much more experience in this realm, your word seems stronger.

I appreciate your adivce, i think i'll be going for the conversion route. Now i need to find an appropriate bike to convert.
