    Balance plug connections for 12S with Htperion 1420

    When charging a 12s 3p Lipo battery pack on the 1420i charger you have the two sets of three 6s balance leads that are paralleled together. So when plugging in the two 6s plugs into the charger, How do you know which plug goes in which charger port, or does it not matter? Thanks

    How to Solar Charge an Electric Bicycle

    I just went off grid moving to Hawaii. I needed to upgrade the existing system here on the property I bought, really rebuild it, and If you can do your own install you will save a lot of the expense and with the federal tax credit of 30% off every thing I bought I am happy with it. One thing I...

    I think this depends on your technical abilities as to if you went to MIT it wouldn't matter if it is your first build, weather or not it is feasible is another story (can be done but a motor on the end of a telescoping fork, is from a design stand point its really incorrect because the torque...

    Need help picking a motor for first e-bike.

    Hey fellow New yorker, well I moved out of the city a year ago after 45 years, now on the Big Island, Well after reading your post the key thing for me in designing your build in what you wrote is: You defiantly want to go as light as possible. Aluminum frame is fine. I would go with a...

    cannondale adventure 4

    I would say IMO Yes, the motor will be putting some stress on your telescoping fork. How much depends on how much torque is applied to the axle, and this is determined by how much power your motor has and at what rate you apply it at to over come loads and how large those loads are. In a...

    Manufacturing in USA will be cheaper than China by 2015

    I just don't think that in 2015 It is going to be so expensive to ship a container of bicycles here from china that it will be cheaper to mass produce them here. (unless there is WW III) And I would bet that in 2015 all the foreign hub motor companies will still be making their products where...

    Manufacturing in USA will be cheaper than China by 2015

    Yeah I'm sure all the peasant and child labor will see their salaries grow at this rate. This article is nonsense, Global manufacturing trends that have been forming for the last 30 years aren't going to change much by 2015. You want to build bikes in the US you will be serving a smaller...

    Use motorcycle parts or bicycle?

    Most motorcycle transmissions are built into the engine casing , their not separate units you could bolt on a bike. I would play around with a Nuvinci .
