Re: a bike for my wife

The white one in the picture, whichever one that is, would be slightly better for a commute to work for one reason, the full chain guard. Sounds unimportant, but not having to tie down your pants is a plus on a daily ride to work. Moustache looks good too. The others have more front gears, but the f...

I wondered how they carried the generators for the chargers in the middle of the desert. Camels.. of course. I was thinking they had used one of those 2 gallons per mile utility trucks.

Yeah, now that I see that bike, I'd want a nice pig heavy DD up there that could push out 2000w without hardly getting warm, but thats because of the load I'd put on er, and the grades I'd ride up. if its steel, I'd weld whatever I needed to put a big rear DD on it.

Re: 48V 500W vs 48V 1000W geared hub motor?

You will need to get the 48v 1000w one to cruise at 25 mph for the majority of the ride. You always start out fast, then slow down 3-4 mph by mid ride, because the battery voltage creeps down as you ride. Most 48v geared systems top out at about 27 mph leaving the garage. 25 mph generally, takes abo...

Re: Hi just to make sure!! voltages, amps and watts

Not sure I'm buying that one. Mostly not sure a half an amp difference is enough to feel, or for the motor to care about in terms of time to overheat. It may be true though, that a big controller wastes less amps into heat, than a tiny one running full out or something, causing that too small to mat...

Re: Has anyone ever switched out their thumb throttle?

Replace it with a half twist throttle is my advice. Especially for longer rides, so you can jam the grip against the throttle for a third world cruise control when you ride a long flat road.

Not knocking the other solution, if you love a thumb throttle. I just don't love em.

After that, my bmw comes alive and REALLY accelerates from 40 to 120. Its problem 0 to 40 is simply that it weighs a ton. Lighter crotch rocket...

Re: Making new E-Bike, question about power

I might be able to answer one of your questions with out hill data. A mid drive that drives the pedals chain can climb a very steep hill at very low power used, this is because you can shift down, and ride up it slow. like 5 mph Riding up it fast costs more power, obviously. A typical hub motor must...

Re: Motor/Kit recommendations

Quietest will be a direct drive motor. The smaller 500w rated ones handle 1500w with ease, and the cheaper 48v 1000w kits with those motors tend to come with 30 amps controllers, which get you into 1500w peak at start up. At max speed around 30 mph, they draw 1000w. To clarify, the motor is rated 50...

Re: Where are all the 1000w cassette motors?

The cassette is almost always too wide, making the space for the motor too tight. So the cassette motor often ends up with skinnier motors in them, which can handle less wattage. Less copper, less magnet, less power. It sure can be a hassle, to convert a good 9 speed to 7. But once you realize that ...

Re: Help a guy have fun again on a bike

Go with a rear hub motor, with internal planetary gears. A direct drive will be heavier than you'd like, and won't coast as nice as a geared hub motor. 500w rated motor in the larger 48v kits is typical, and 1000w will be plenty of power. Go with something like that from Grin, or you might consider ...

Run your battery conservatively, and your 12v sections will need very little balancing.
