the seller told me that last time she made 75km range and still 1 bar left so range about 90km. and she used about 600kms. I am worried about the battery because I have no idea if I could put DIY battery in Giant bike.Depends on the battery condition. You should usually assume you’ll need to replace it when making a decision, especially after 5 years. Just poking around, looks like a battery goes for around for the asking price of the bike itself.
Knowing that as the seller, I’d probably make the same decision to sell the bike cheap, rather than buy a new battery, if the existing one was getting tired.
Looking online, it looks like the battery has 3 prongs, +, -, and a wire that communicates with the charger for their smart charging feature, so less locked down than most proprietary setups, like Specialized, for instance.The fact that the battery is probably 6 years old now, and a proprietary shape that might make it tricky to replace, would deter me from buying a bike like that.
At best, that means a no-longer-available battery would need an elaborate heart transplant to bring it back when it's worn out, or an external battery would have to be strapped on somewhere. Either one is an option (as long as there's no secret electronic handshake involved), but neither is as easy as switching to a new Hailong pack or the like.Looking online, it looks like the battery has 3 prongs, +, -, and a wire that communicates with the charger for their smart charging feature, so less locked down than most proprietary setups, like Specialized, for instance.
It looked available at $700. It's a money maker for them.At best, that means a no-longer-available battery would need an elaborate heart transplant to bring it back when it's worn out, or an external battery would have to be strapped on somewhere.

Hopefully it will stay that way for Giant, or they'll stop making and selling it.It looked available at $700. It's a money maker for them.
Hefty profit for a 36V battery though.Hopefully it will stay that way for Giant, or they'll stop making and selling it.
