It sounds like you are running 48V 12Ah lead battery right now. If you went over to a 48 volt 15 amp hour Ping you would see a drastic improvement over what you have right now. You might get close to double your range with a lot less weight and the voltage won't sag on you as much when the...

Also keep in mind that the BMS draws power from only part of the battery. If I let my battery sit for a week or two without being used the third light in from the end won't light when it is charged. I have to leave it on the charger for 6-8 hours to get it back up to voltage and get the light to...

I'm in Philadelphia and bought the exact same battery you are getting earlier this year. It took about three weeks to get here. It now has a little over 1200 miles on it and works great! Still hitting 30 mph and getting over 20 miles out of it at full throttle.

What kind of brakes are on this bike?

If you have to replace a connector check out http://www.wirecare.com/deutsch-connectors-main.asp They are some of the best that I have found at a decent price.

Rockwool is pretty cheap and should do the trick.

Yeah, two motors sounds like fun but I have to show some restraint. I don't think my wife can get too mad at me seeming how the price of the frame is less than her monthly car payment and insurance. And since I already have a good battery and some extra parts laying around the rest of the build...

I've been wanting one for a while and couldn't pass up on the price, I grabed the last v3.0 frame. Should be a fun build, I'm thinking about a front wheel motor to help keep some weight off the rear.

You can buy the kit with out the batteries and pick up some lead acid batteries from a retailer like batteries plus. The batteries they use are nothing special and you should be able to pick them up pretty cheap. As far as keeping your batteries warm you can mount them in a bag with some...

Can you explain where you are measuring the battery voltage at when you say it drops to 12 volt with the controller connected.

Very interesting. Is this going to be a pure electric bike? Are you going to relocate the bottom bracket?

Looks like your having some good fun. One recomendation I have is that the front suspension has to be in between the handlebars and wheel. It looks as if your handlebars are still going to be connected solid to the front wheel via the forks. Please be carefull with your material choices, good...

Sounds like a bad CA. Take it out of the circuit and give it a try.

Try turning your bike upside down or putting it in a stand to get the rear wheel off of the ground. Once the rear wheel is free to rotate try spinning it by hand and see if you get any noise, if not try spinning it through the pedals. You should be able to get pretty close to hear where the...

I have a 48 volt 15 ah ping battery that I keep in an Ortlieb trunk bag on a tubas rack. From my research Tubas has the highest load rating of any rack I could find, which is important with a battery that heavy plus other stuff I carry in my panniers. The 15 ah battery fits in the Ortlieb trunk...
