So far it's gone another 401 miles without motor problems, though yesterday (or sometime recently) I managed to spin the axle 90 degrees in the torque washers, gouging a line in the axle:

Crossposted from Fusin's original thread about the motor:

It's been performing well for another 652 miles+, on top of the 511 previous to moving it to Delta Tripper. So nearly 1200 miles on it without breaking it (yet).

Only problem is the frame wasn't good enough to hold against the torque washers, unlike the bike frame, which was fine with it. It ripped out the inner dropout (left side of motor) and carved the flats of the axle on the other side where the torque washer was (which didn't move in the dropouts, but hte axle i s alot softer than the torque washers---that is a big failing; the axle should always be harder than whatever holds it, so that it doens't have to be replaced when such a failure occurs, only the holding item does).


There is another issue, but since Fusin won't sell me the tool to open the motor, and there's no dealer here who *could* get the tool and do it, I can't tell what's causing it for sure.

There is a new noise in the mtoro the last 3 weeks or so, which sounds like it's coming apart and tearing itself up--but it does nto happen all the time, and it is just a very disturbing noise for now. At first I thought it was something rattling in the rim, but now AFAICT it's soimething in the freehub/cassette mechanism; perhaps a pawl or bearing has come loose in it and is rattling around in that part of the mtoor.

I do not presently have it on a bike that I can check to see if this mechanism still works as it should; I don't even have a cassette on it, to save a bit of weight on the trike since it's a right wheel where no chain could reach that side anyway.

Whatever it is, it apparently cant' get into the rest of the motor, or it would have already gotten into the planetaries or the rotor/stator interface and really damaged something. But if it is indeed part of the freehub mechanism, it is strange that it would fail when it has almost never even been used for pedalling, and only a few hundred miles on it in freewheeling mode.


Anyway, until I can get the motor apart (have to make a tool for it I guess) then we won't know the actual noise source.

Crosspostedf rom the Delta Tripper thread, regarding the Fusin wheel:

texaspyro wrote:How many SPERM (spokes per mile) does this thing get?
Actually, I have yet to break a spoke or wheel on this thing. [ed: regarding the Delta Tripper as a whole, not the Fusin wheel] Mostly I think it's because it's not yet constructed in a way that allows a load as heavy as I have put on CrazyBike2, and because it has two rear wheels to distribute what loads I have put on it.

There *is* more impact strain on the wheels because the frame doesnt' flex like CB2s' (being much shorter than CB2), and there is way wya more sideloading on the wheels, so I am surprised that nothing's broken yet.

I *have* broken off the *entire* wheel and part of the frame, but that wasnt' loading, but instead motor torque at the axle combined with insufficient nut tightness and too thin a dropout/frame, and only torque washers rather than arms. The fix of more than tripling (probably quadrupling) the original frame thickess where it ripped the axle thru the dropout has so far worked fine, along with wrenches for torque arms. It's survived 377 miles since then without issue (but it was about 461 miles to break off in the first place...).


Total mileage now is 838 miles, and after my work commute today will be 843 on the trike, and about 1350 miles on the Fusin motor wheel itself, which hasn't broken any more spokes since tensioning them all as properly as I could (which they weren't from the factory).


I think I mentioned the almost-small-orange-sized rock I hit with the Fusin wheel, which didn't apparently damage anything, though I expected the wheel to come apart from it.

The post above was the day before the housefire; the motor (and Delta Tripper) continued to see use after that, until I disassembled DT to make the SB Cruiser:

Then this motor sat unused, until now, when it's been fitted to the new trike here:

The post above has some info about a noise problem it has, and opening it up (finally), though I havent' quite gotten the cover off yet.

I figured it out, and got it opened up,

so here's the insides:

And teh noise was the outboard freehub bearing, or rather, what was left of it
