Re: opinions about this 500watt model & hill performance

unless your wife is under 100 pounds, i wouldn't expect a 500w geared hub motor to survive climbing a 16% hill. 8fun is Bafang's western name brand. Bafang make a good motor, and if you modified the controller for more power, it might actually make it up the hill. but i doubt the motor would survive...

Re: First E-bike Conversion advice

Skip those 350w motors. They aren't robust enough to survive off road. a 500w Bafang or MAC is what you need. And if cost is an issue, the direct drive hubs are still a good option. Heavy, but bullet proof with only 1 moving part. They make a great motor to get started out with. They have some advan...

Re: New DIY project (Stealth Bomber-ish clone), advice on parts - starting with wheels/tires

Looks like a good combo so far. Ive been curious how those Ranger 3.0 work out. Since you're building up the bike, you probably should go for a wider rim. for a 3" tire, I'd want a 45mm rim (39mm inside width). 32 hole for the front will be easy to find. for the rear, you're going to have a fun sear...

Re: brushless Dc motor controllers

A motor's speed is based on the voltage supplied. And the speed is basically linear. If 10 volts gives you 10mph, 20 volts will give you 20mph. 100 volts will give you 100mph.... as long as you also have enough amps to cover the wattage needed to go that speed. If you take the battery voltage you ha...

Re: planning new ebike build - several questions

looks like you've picked a good overkill motor for what you want to do. combining that with a ~52v, 40A controller will give you 2kw of power, a bit more power than a moped in a vehicle that weighs 100lbs less. It should give you all the performance you need. An 18FET controller is what I use on my ...

All of those 1st gen motors are crazy quiet and smooth. They have that slant groove stator that eats some efficiency in trade for silkiness.

Re: Run motor with insufficient amp batteries damaging?

If the BMS does it's job, it will shut down the battery at any draw over 100 amps. But it's designed as a safety device, not a means of current control, and i wouldn't rely on it. You should be relying on a controller, not the BMS to handle the current draw.

Cromotor is going to be the most powerful at 135mm. But "most powerful", "fastest", and "best" aren't the same thing.
