Did my first test with the 15s 60V battery and what a difference - top speed on level road went from 15 to 25 MPH, hope to test on a hill later today.

Decided on the Magic Pie3 hub motor and purchased off eBay http://www.ebay.com/itm/261548446563?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT, it arrived in a couple days and fit right into the Kona frame with no modifications. The 10mm flat on the motor match the 10mm dropouts so I...

made_in_the_alps very nice looking bike! I am on hold waiting for components, still haven't received my batteries which must be on the slow boat from Poland:) I ordered a cheap spot welder from China and received it in 3 days so now I just need the batteries to start on the pack. I have...

Mine also had Garbanzo Stinky decals over a crappy repaint - must have also been a Killington bike as I am only a couple hours from there.

Thanks for the info, 2000 peak watts is about what I figured, I have decided to change to a 5P 16S 60V pack so I can minimize the current draw through the controller, here is a picture of the new layout with the BMS: This should also allow me to pre-assemble and test all the 5P packs separately...

I don't plan on finishing the frame - I like the bare aluminum look and going over it with some Scotch Brite leaves a nice finish.Thanks for the tip on the Marzocchi, I already bought the seals (03 Super T Pro) but I do need some washers for the upper seals - I will check into their motorcycle...

markw - mine is a L (16"), triangle is definitely tight which is why I swapped to an air spring to get a little more space. izeman - you are correct about the travel, I made a cardboard template of the box and cycled the pivot through its range of motion to make sure I still have clearance: My...

Kepler - great build, thanks for sharing I hope to do something similar to your battery pack design on my build. Anything you would've done differently in hindsight?

Reassembled frame and replaced spring damper with Fox air shock which adds a little more room for the battery. I could not get a heavy enough spring for the old spring damper to handle my weight and the additional e-bike components, the air shock will allow the rate to be adjusted to match the...

Starting my 2nd E bike build, 1st since discovering this forum 2 months ago. My first build was an electric trike for my Masters thesis about 8 years ago (https://zeept.wordpress.com/), it is amazing how much has changed in the field since then! My trike has sat dormant in the basement since...
