G060 Bafang Hub Motor voltage question

[Goose Bikes]

Hey All,

I’m looking for more speed, can it be done?

I currently have a 48v battery and I want to increase the voltage. I know largely the controller is what won’t be able to handle it (I’m unsure of exactly what controller I currently have). The display for the bike is a sw900 display, for more information. If that’s the case, does anyone know any controllers that work with the G060 model that can handle 52/60/72v?

Can it handle a 72v too with the right controller?

Currently maxing out at 28mph and I’m hoping to max out closer to 35/40mph as it’s more safe to keep up with traffic than being always slightly slower. All help is welcome. I’m fairly new to the e-bike world so my knowledge is quite limited. With that in mind, a simpler option may be most suitable for my situation. Thanks!

You can get more speed, but you'll cook your motor quickly if you're shooting for even 35mph.
This is a G60, comparing 48V and 72V, both using a 20A controller. It gets to 32mph, but it's running too hot (over 100C isn't good).

Upping the controller current to 40A gets you to 35mph, but now you can cook an egg on the motor. Those speeds aren't safe though on an ebike anyway and without proper gear.

Would I be able to run a 52v battery on the bike instead and have the motor and existing controller be okay? Even if I could reach 50km/hr (31ish mph) that would suffice for my situation. I think with a 52v battery that would be doable as I can get 28-30mph already on the bike. I'm debating getting a new battery regardless as the range on my current battery isn't great, especially with voltage sag. Thanks for your help

Is the bike in question a RadRunner or similar with 4x20" tires? If so, the following video should be helpful...

If you change system B in the simulator to a 60v battery, and same 20A controller, you hit 31mph with no “overheating” (but running hot). 52V will barely get you 1.5 mph at most. You can change the voltage with the custom battery option to a fully charged 52V or 60V battery if you want to model that.
