BAFANG BBSHD 1000W Vs hub 3000w - questions.

[Fuzzynuts]

Hello guys.

I'm about to buy the BBSHD 1000w motor for a project that could take up to a few months to be able to afford all the parts.
The deal I've come across is on aliexpress (im not sure if linking to aliexpress is allowed but will link anyway)
the battery says its a 52v 20Ah battery. Here is the link
I also understand this should see me at speeds of around 28-33mph with the default bfang controller maxed out.
According to e bike battery calculator Im looking at a range of 48-52 miles with minimal peddling.

I've also seen an after market mod called "phase runner" that can be used to really beef up the 1000w motor but im unsure as to what improvments this will bring and if a bigger battery would be needed.

Im thinking a 52v/40Ah Rr even 50Ah would actually be the better idea for a battery - but would the phase runner/1000w bfang handle a bigger battery like that even jumping to say 72v/40Ah?

Essentially I'm looking to get the most out of the BFANG 1000w in theory and this is the info i came up with.

Outside of that - a 3000w hub motor I've seen some guys clocking in at 48mph - With a 60v/24.5Ah battery, but they said they wish they got a a larger capacity battery. Imalso aware anything above a 3000w hub on a mountain bike frame is not advised, as there is not enough weight pushing the bike down for stopping traction.

For ease of buidling the BFANG has this area won IMO and its much easier to repair a rear flat.

thanks.

So much depends on how you want the bike to perform and how and where you intend to ride. A 1000w mid-drive may make it easier to change tires, but it will surely wear out chains, chainrings and cassettes faster. And I'm not at all sure it will be easier to build. A rear hub motor installation is darned simple. The mid-drive will give you more flexibility and probably be more efficient if you ride on hills a lot - especially steep ones. If your goal is speed, the 3000w motor would be better. If your goal is reliability, get a 1000w direct drive hub motor.

The battery range seems about right assuming the capacity is what is claimed. I travel at moderate speeds (20-25 mph) and even in a hilly area, I consume around 16wh/mile (on a StokeMonkey mid-drive averaging about 100 watts of pedal output). That said, I'm generally skeptical about unbranded Chinese batteries. It may work out fine, but I'd go in eyes wide open and assuming the capacity may not be quite as advertised and the battery cells may not last as long or perform as well as a name brand Panasonic, Samsung or LG cell. As with motors choosing battery capacity depends a lot on your intended use.

There should be lots of discussions about this on various threads. Perhaps you've had a chance to read some while waiting for a response to your post.

Hey man, i went with the bfang with a 52v 25Ah battery - haillong.
52v 24.5AH 50A - samsung cells.

I do tend to mix in some hills - but id say less than a qaurter of my entire ride will be hills,im aware you have to take a spare chain out with you just incase, i was told anything other 1000w on a mid drive needs a few mods, but ill be happy with a flat speed of about 33-37 on stock controller, and some grunt up hills. If you jump to a 72v battery you have to look at better quality chains and puncture proofing the tires.

Realistically you won't bust a chain badly enough to need a whole new chain, you can just repair it completely legitimately with a masterlink
