I don't wish to hijack this thread, but perhaps someone could answer a related question on amps and watts, still new at all this.
I'm trying to decide between 36v and 48v 500 watt motors - mid-drive or hub, but primarily hub for a Specialized Roll, but unclear of what the difference in volts makes for speed or power.
I'm also curious about the comment upthread about just two motor sizes for bafang hubs. Their watts rating is based on volts then, for several combinations - 36/350/500 and 48/500/750/1000?
I didn't realize the higher watt motor was actually larger as well, for either hub drive or mid-drive. The 1000watt must be with 52v then and a controller to provide enough amps.
Wifey surely doesn't need or want 28mph, but 15-18 would probly be great, and some help with hills. I was thinking mid-drive, but now moving to the hub concept, they're cheaper and she can just coast along with a throttle - that's her riding style. We're old, she's no speed demon, and my motorcycle days are over. LOL Casual paved path riders here.
