Re: Question -n Using ebike pack to top up 12V trolling battery (AGM) via MPPT solar charge controller.

Thanks for your assistance...I failed my first attempt with a 48V to 12V DC DC convertor rated at 30 amps out, used to power golf carts. It ran for a while, but failed when my Minnekota was run at 100% for several minutes against a tidal current. I suppose if I hooked up two DCDCs of this size, it m...

Question -n Using ebike pack to top up 12V trolling battery (AGM) via MPPT solar charge controller.

I would like to use my big ebike packs to top up (in real time as I am trolling) an AGM gel cell 12v Battery...Can I just run the ebike pack through an MPPT charge controller directly to the AGM pack in parallel, along with my trolling motor from the AGM pack, as I am running the motor? Assuming the...

Re: Full suspension tadpole trike pulling a bob trailer?

I have a Bob trailer that I use on my non-suspended tadpole trike for camping gear and it works very well in the forward direction, efficiency-wise. However, they do have a bad tendency to jacknife if you "back up the truck" which I imagine would be a problem for folding joints on a trike frame, pos...

Re: Four wheeled bikes

Usually too wide to fit on a bike path as well. The posts on bike paths to slow bikes down at road crossings seem to be set about 40 inches I think - that works well with my trike which is 32 inches wide, but I have to pay attention at speed, which is what the posts are for. That gives me about 4 in...

Re: KMX Trike with TDCM IGH & Phaserunner

Not sure if it helps as each trike is a bit different, but on my Performer etrike - a very similar build to yours, with batteries under the seat, and rear direct drive hub motor, I find that 1/16" toe-in is just right. Either side of that even a 1/16th affects the handling. You got it right with you...

Elegance is the reason. I don't like putting power through the drive train for good rea...
