Re: High wattage hub motor for 150mm drop out required

As for me, i need to find a guy in Toronto who knows how to lace moped/motor rims to e-hubs. It's not difficult to learn lacing; the hardest part to actually do is truing and if you don't need to use rim brakes then lateral (axial) truing is less important (making it easier as radial truing is what...

Re: Mac motor washer position outside dropouts

The lead is already terminated so I cant reposition them. Terminated in what connectors? Many of them are small enough to fit inside the nuts/washers, either directly or by splitting the phase connectors apart, or removing the contacts from the shell(s). Whether it will matter depends on the should...

Re: Batteries in a series and parallel question

Nobody offers anything that fits mine either, hence the SB Cruiser trike (and CrazyBike2 before it). There's a bunch of members here that have done completely custom stuff, and lots of members that have customized "regular" bike setups to better suit their needs. So lots of examples to look at to he...

Re: My solar-assisted custom tricycle FOLLIES

Yeah, it's in the front fork: https://endless-sphere.com/forums/download/file.php?id=223579 The clamp looks good, but it doesn't take much movement (rocking) to make a thunk. It's also possible but unlikely that the axle on one side is cracked thru and so it's rocking on that side--this would probab...

Re: ? Gross Brake = 3000w Brushless Hub motor

My basic question is whether or not a stock Zapino with a 3000W brushless hub motor meets the CA DMV / AB2173 legal definition of a motorized bicycle. The motor rating is irrelevant, because it does not determine how much power the bike has. (unless the law specifically calls out the motor rating i...

I like the idea of what you want to do, but I think you've got a steep learning curve ahead of you. ;) And I get the feeling your design team is obsessed with hexagonal shapes. :?

Re: The SB Cruiser: Amberwolf&Dogman's 2WD CargoTrike&DogCarrier

So far it's been nice and stiff after the repair. Since it's been colder for longer at night, the battery performance is a little degraded--acceleration from a stop to 20MPh at full charge had been almost down to 3 seconds back in October when a night in the low 70s or high 60s F was cold; now halfw...

Re: Freewheel Maintenance

And here in Phoenix, the extremely fine flinty(?) dust tends to grind things away if you lubricate them with anything that gets sticky--I've had better luck with zero lubrication than with just about any dry or wet lube or grease on anything I can't seal against dust.

Re: Surface resistivity & volume resistivity?

Ah--when I clicked the link, a blank page opened, no article, so I didn't see that.

Either way, you still have to know which unit they're actually using, but you could "assume" it's mm since the other unit on the same line is mm. :/

Re: Question about hobby charger amperage fluctuation

Are you running the charger in "balance" mode? Or in "charge" mode? At least in the RC charger I have here, the former does exactly that--maintains balance of the cells while charging. THe latter just bulk charges and stop charge if any cell exceeds the limit for the cell type I've chosen. Also, hav...

Re: Surface resistivity & volume resistivity?

You'd need to find out from the manufacturer what unit of measurement they intended to (but did not) put there. Given their other measurement on the same line is in mm, then it's likely the unit is metric, and probably mm, but you'd have to ask. If none of their data sheets use a unit there, then th...

Very exciting to have received the front direct drive hub motor for 60 to 96V! First time ever I might try running a higher voltage motor on a lower battery supply.

Re: v-brake front fork mounting points?

If you're going to use the brake bosses as pivot points (or have other pivots along the same axis), you have to use smaller diameter motors and in place of the brake arms, or else it won't be on the rim, it'll be on the tire at an angle to the wheel some distance from the fork.

Re: BMS problem

Hook the volt meter to the lowest of the cells, and watch it's voltage when you connect hte load to the BMS. I'd guess that on connection, the capacitance in the load (amplifier) is drawing so much current that the voltage of the cell(s) drops below the BMS's cutoff point, -or- the BMS has a current...

Re: Super capacitors to save battery life?

FWIW, I'd skip the caps; not enough benefit for the extra volume and weight. First, I'd parallel your existing packs so the load on each one is only half of what it would normally see, so it's voltage sag would be that much less as well. This should also get you more total range out of them, because...
