Which of the top tier
ignoring price
make the most powerful (torque not speed)
without sacrificing too much reliability / longevity?
john61ct said:Heavy tandem / cargo, long steep hills.
DD alone and ungeared may burn as speed gets too slow.
Thinking a second motor, geared in tandem would increase capacity, add "limp home" redundancy.
Will often be off pavement, need the bounce, likely fattish tires, 26" is a maximum total O.D. not rim size.qwerkus said:Tandem + hills + large wheels (26+) = tricky for hub motors.
Mac is on the list, and I just asked about gmacAHicks said:Surprised nobody has mentioned the MAC and GMAC geared hubs? They are just about the strongest available.

I started w/ a MXUS geared over 10 years ago I got from the long gone Amped Motors and although I don't think it lasted quite as far as yours, it was a great motor. Eventually, the left side axle bearing started to go, possibly because salt air/water where I used the bike. I could hear/feel it when the bike was leaned when turning left. I could have replaced it, but I just gave it to a kid in the neighborhood.AngryBob said:MXUS - what I choose. Nowhere near the numbers for Bafang, and, specifically for their small geared units, very, VERY few breakage reports. Six years, approx 15,000 miles, zero issues.

Want to start off without suspension, stick to low & slow.
Yes I am considering the one big custom mid drive, but no skillz nor tools right now, so looking at maybe going with multiple "plug and play" motors for a first round. Have family members I can hand down to later, so no waste.
I'm basically willing to try one "best in class" of each type, with a focus on the low speed torque, experiment with each, combine.
So this thread, geared hubs. . .
Does the Grin "gmac" slot in with generic mac on that list, or do Justin's enhancements slide it up a bit?
For me, always a focus on the low speed torque scenario, never speed.

neptronix said:Variable regen is a controller feature that works with any motor that can do regen.
The GMAC is not any more/less complex to deal with than a DD.

Which of the others offer it?
