Re: Build

Both those things take more finesse and coordination than you have in your feet. When I rode a motorcycle for daily transportation, I wouldn't touch the rear brake at all for days at a time. Would you have left hand rear brake, right hand front brake, right hand throttle on your emoto, Chalo? I gue...

Then if there new rider that ride on a left back brake if they get a gas Dirtbike then it would take more getting used too. Exactly, now why is the rear brake on th...

Yes, no because I ride well, so far. What does any of those questions have to do with a foot brake?
Can you explain why manufacturers such as Zero should keep foot brakes on Electric Motos?

Re: Dirt bike build

I'll never understand what motorcyclist like about foot brakes on ebikes, left hand dexterity > right foot I take it you do not ride motorcycles?

Re: 3DE - 3D Printed Carbon Wrapped e-bike frame

Super cool! Any chance you could print most of it in "vase mode" aka single perimeter, and then go for carbon lasagna? Perhaps fiber glass could be a place to experiment!

Hey Chris, it would be really cool if you posted the dxf and/or stls online with some instructions. Some of us have limited fabrication tools and just want to motorize the ...

Re: Super fast charge

You of course **can** charge from a 100% Full pack to an "empty" one but then if they are the same Ah capacity, bith are now at 50%. You need to (MUST for safety) limit the current transfered when initially paralleling them. Both problems can be solved with a quality DC-DC **charger**, bu...

Re: Super fast charge

The batteries can't be swapped, I guess my question is, can a battery be used as a charger. I know there are faster chargers. The question lies in using my second battery as a charger.

Super fast charge

Hey guys, I have a 12s battery identical to the one in my bike. Would it be smart to have some sort of current limit in the bms and just plug in my bike to the external battery when I get home? The external batt would be permanently connected to my charger. How would you guys go about implementing t...
