Can you get us a few more pics of the crank area? And were you looking at something like the Cyclone motors or a BBS?

I can't quite tell from the photo which SA hub you have. SA has a pretty tough monster hub that I think was developed for rental bikes. The older design...

The Bafang mid drives each have their own unique chain ring mount and don't even interchange with each other. You can get what are called BCD adapter...

If your project is still that far out keep an eye out for used stuff. Pretty good chance you can find a pair of 24v packs in the next year, maybe even...

I like their comparison chart. Looks like that marketing department didn't even run it past an engineer, even the one that drove the train they rode...

With a trike you have a lot more mounting options than typical bicycles. I would be looking at used 'scooter packs'. There always seems to be tons...

Do you already have the Eclipse? If no then maybe a BCD adapter and use standard chain rings? That way you could go bigger than a 48t if you wanted...

17ah seems reasonable based on what you said. The smaller 12-14's could be a little thin for 40 miles. I have made 40 miles on my 13.5 but nothing...

Good to hear you are running. Magic sucks. Not good for the confidence. I would rather find the smoking gun so to speak.

Make sure to look at your new chain to see if its got a direction and an up and down. Some do and work a lot better if you put them on correctly. ...

Never heard of them till you mentioned em. Not a lot of details on their website perhaps because all are sold out? or maybe I just can't find any specs...

[73Eldo]

It didn't come with one or there wasn't an option to buy one from the same place as the rest of the parts? Typically if a system is set up for assist...

Looks like it may be alright. 73mm bb which is good. Doesn't look like some oddball thread. Looks like its the style where the bearings stick out...

[73Eldo]

With that size the BBS02 should still be an option. IF going HD then get the narrow one of the 3 options.

[73Eldo]

You could likely get more range from less size and it would look a lot better if you went with some sort of 18650 pack. If you are fine with that top...

I didn't click on the link but what I have heard from others is over the last several years a typical cost per bike to ship one from China to USA per...

[73Eldo]

Sure it could be done. Questions to answer would it be worth it and would that change the legalities of where you could operate? An electric bike can...

6 hour ride or 6 hour build? If its a t6 hour ride where is the report? 6 hour build that's pretty decent for someone that hasn't done one and real...

[73Eldo]

If its a steady load I'm not sure why it would drop near the end. It doesn't seem like there are too many use cases that would act like that so seems...

Its too late at night for my brain to try and process your drawing. Since you need a new pack anyway how about building up a dual 24v system? I...
