Re: Freewheeling motor and coaster brake?

Yea I have been trying to convert my phantom to a regular bike. Nightmare. I have a 16t ss sproket and it is just a half link too long. Going to try changing the crank sproket to a 40t or something maybe. Have a look at this tool: http://eehouse.org/fixin/fixmeup.php It will allow you to figure out...

Re: Why never see metal cast around wound stators?

Wouldn't encapsulating a stator with electrically conductive metal squander a huge amount of energy to induction?

Really, you want to encapsulate it with diamond. Excellent thermal conductivity but electrically insulative. Let us know how it goes.

Re: Freewheeling motor and coaster brake?

The Prodeco Phantom bike has vertical dropouts, which makes it incompatible with a coaster brake. Since your question is interesting, I'm going to address it with the assumption that you'd be willing to switch to a suitable frame with horizontal dropouts. It would be tricky to get enough wrap around...

Re: Good for the environment? Maybe not so much

At least someone who buys a scooter is less likely to have a monster pickup truck though. Someone who uses a scooter instead of a car is one thing.

Re: Single shaft spoked hub motor for fatbike/trike wheel - Does it exist?

Choosing fat tires doesn't diminish your motor options, but stub axle wheels do. Maybe some of the trike guys on the forum know of single sided motors I'm not aware of.

Re: 12 turn Hub-motor vs Mid-drive for hill climbing ??

The difference between the two kinds of motor for hill climbing is that you can configure a hub motor for a certain steepness and load, but you can potentially set up a mid-drive for any steepness and load.

Re: 110V AC e-bike

If it's cheap or free, why not? You could even run your bike in circles on a really long extension cord. Note that the duty cycle of even a professional grade drill is much less than that of a traction motor. So you might wear the gearmotor out quickly. No big deal if it's cheap or free, and you did...

But in case I have a single gear spur arrangement, how difficult will it be to change ratios later? The distance between gear centers will vary with ratio, and it's difficult or impossible to change without remanufacturing parts. Chains are easy. They're tolerant of imprecision and wear, and they r...

Re: Schwinn cruiser a BBSHD candidate ?

That's a one-piece crank, which uses a larger diameter bottom bracket shell than the BBSHD is designed to fit into. Luna Cycle sells eccentric cups that allow BBSHD and BBS02 drives to be attached to that kind of shell.

Looks like it would be tough to get anything in between the covers and the motor housing to attempt to pry them off, particularly if there was any sealant of any sort used to keep water out. Cheap chef's knife from the thrift store (or one you're tired of looking at, that isn't worth resharpening)....

I think that requiring that every vehicle be a hybrid has been the logical thing to do for a decade, at least. But it has been fought by auto, and oil interests.
