If hub motors have a weight limit of 200lbs, is there one that can handle more? Like the german made Heinzmann hub motor ? I think large cycletrucks should be able to handle 600lbs not that they would be hauling that much weight all the time. But I haul a total combined weight of 450lbs often enough to know what I would like to be able to haul. More than 600lbs on only two wheels would be very dificult, but three wheels are legal on a “pedal powered” vehicle in the US.
What mid-drive motor would you recomend for a large slow cycletruck for steep hills?; [Euro-style but for USA]. Ya I know nothing that powerful is legal, but it will be soon because at 12mph I need to draw about 1500w to get up some of our hills.
How about the Bafang BBSHD with better micro cogs [not controlled down to 1000w with a PAS crank sensor]??
I really like my large cyclone's planetary gears, but I want to be able to recomend one that is easyer to mount.
Actually I am not sure that the better grease does not cure the problem of the tiny cogs wearing out. I am going to use the sticky transmission grease, maybe even with some PTFE in my cyclone3000 gears.
Do you know where I could get the very small cogs for the BBSHD in composit or aluminum? Or is the best thing to do is to just buy extra nylon cogs, and replace them once in a while? Which could be expensive for someone that cannot work on their own bike.
If the BBSHD (in stock form) is 1600w peak? Can the controller be programed to a higher output?
It looks like the Cyclone [Mini?] 1680w needs a better controller...? I still have not found the causes of the lurching problem that was posted on the Lunacycle's forum. Looked like “chain suck”caused by a tight link, unless it was the throttle or controller.
I like the idea of a belt drive for a single gear. But as for an internal geared hub; does any one make a realy strong three speed that can handle close enough to a 100Nm output?
My Cyclone3000 already bent one of my rear cog sprockets on my MTB cassette, so I am thinking about these and I could use the larger chain I wanted to before I discovered that I realy do need at least three gears.
Nexus-3 IGH “It seems to be able to easily take 1500W of power”?? But even better the planetary gearing in the “Sturmy Archer 3 speed IGH the gears are big and have lots of teeth”.
Is that drawing 1500watts from the battery, or the output?
