Re: Is REGEN, really worth it ?

Bicycles that drag are a drag, is all. John rides motorcycles, and has different priorities. Any bike with a motor is technically a motorcycle, and anything you ride on with 2 inline wheels is technically a bicycle. If you want to talk about arbitrary legal definitions then it depends on where you ...

Re: Is REGEN, really worth it ?

Lets say you have a 20 mile commute using regen in the best conditions for it to be used, what is the max voltage input 1 can expect back into the battery ? 5% - 10% max ? Are there any negative aspects to using regen , as far as wear and tear on the motor, magnets, controller, battery ? "Best cond...

Re: My Wife Sold My Bike

The day my wife gets to "allow" me to do anything is the day I say "next" after she hits the curb. I do agree with "happy wife = happy life", but it takes happy me as well, and that means doing whatever I want. The key is finding one who's perfect happy with you doing whatever you want.

Sorry, not a chance I am using ATF!! I've done that before, and the mess it made was diabolical.
It sounds like you didn't seal it properly. OTOH if it caused a motor malfunction I'd like to hear about it.

Re: 8kw Enduro Frame Build

That's definitely not the small square tubing based Enduro like sold by em3ev, which has tons of wasted space in the construction. This one looks cavernous inside...

While he said geared hubbie, don't forget he's done 10 years with lead and a crap brushed motor with many replacements. Take the full step and go with absolute reliability as an upgrade. So what if there's a 5-10lb weight penalty. Compared to his lead anchor there's still a big weight savings to enj...

Re: 8kw Enduro Frame Build

What's the brand and source for your Enduro frame? What is the weight of the frame with swingarm? It looks significantly different than the one I have in some good ways...primarily that it's a monocoque structure instead of square tubing based, and I like that for the space savings. To me tubing jus...

Re: Definitive Tests on the Heating and Cooling of Hub Motors

Part of this is due to the motor being less efficient at the lower speed ??? If you're pumping the controller's current limit into a motor, it doesn't matter at what point on the efficiency curve the motor is operating, does it? ie The copper losses are the same? If you add in the iron losses, then...

Re: Could Electric Bikes Be Killing Off America’s Car Addiction?

An electric car is not much greener than a combustion car. Unless it is half the weight and size, it is not a significative improvement. I think it's a pretty significant improvement in terms of energy and resource usage, but it's not a complete solution - just another step along the path to "bette...

Cagers and riders are mostly different animals. Hens would not fly to save their lives. I'm glad this animal changed its spots.

Re: Are ebrakes sufficient?

I've never heard of locking brake levers, so I need to look into that. Most of my ebikes require 2 cutoffs due to 2 controllers, so I do one with the rear brake handle and the other on a horn button. They're regen so I use them all the time and it's second nature in emergency braking. The switch on ...

Do a partial fill of your BPM with ATF and it will make it much more quiet as well as make it dissipate heat better. Cheap and easy.

Not 100% essential IMO.

It is an essential safety feature of any ebike, because it's there to st...
