    Riding for free with solar charging!

    Thanks Dogman. Yeah, I bought the biggest panel that was shippable by common carrier so I wouldn't have that bottleneck of enough charging capacity. Now Kyocera only make the 140W in the same size and it's cheaper than what I paid last summer. The panel can probably provide enough juice for...

    dak664, My MPPT charge controller only cost $200 and is far superior to the PWM charger that it replaced. The MPPT charger outputs way more watt hours per day than the PWM charger did.

    MPPT stands for Maximum Power Point Tracking. It is generally thought to be the most efficient. http://www.morningstarcorp.com/en/products

    Riding for free with solar charging!

    One other thing: Originally I had a PWM type Morningstar Sunkeeper12 charge controller that was only $70 but it could not keep the deep cycle battery sufficiently charged to cover charging for my commute. I went ahead and bought the MPPT charger for $200 and it was night and day as far as being...

    Thanks! We really love the Leaf. It was the inspiration for going even more efficient with the bicycle.

    Riding for free with solar charging!

    Hey y'all, I wanted to make a quick post for anyone wanting to run their bikes on solar power only. I built my A2B Metro a few months ago with 72V power and wanted to utilize a 135W Kyocera solar panel I had for charging my R/C batteries. The setup cost me around $1000 so it wasn't cheap but...

    UltraMotor A2B Metro needs a new battery!

    I might have a primary and secondary A2B batteries available for $250 each plus shipping in a few weeks. I have ordered hobbyking lipos for 11.6ah 72V.

    The reverse function of my Losi Mini T is variable speed.

    variable regen throttle and controller for ebikes.

    One thing the throttle reminded me of was an electric R/C car I have that slows down really fast if you reverse the throttle. Could be a clue or a place to start to figure it out. Vectrix might have some sort of patent protection.

    variable regen throttle and controller for ebikes.

    I test drove a Vectrix VX-1 the other day in Austin, TX and I loved the throttle. The regen function being built into the throttle is really super cool. It was very interesting and effective to use the throttle to stop the bike. While the Vectrix was a little larger and noisier than what I was...
