    My Gravity Hybrid E-Bike

    Another bike build for me as I continue to search for E-bike "perfection", or at least my idea of it. It started with the notion that I would build a multi-purpose bike using a 29'er disc frame and the Bafang mid-drive. I picked up the bare frame off of craigslist. It can handle some of the...

    My Electra Townie/Bafang BPM Cruiser E-Bike

    Another E-Bike rises from the ashes. Ok not literally...but this bike did start out as a much neglected Electra Townie that I picked up for $50. The original front suspension fork was completely rusted and seized, the wheels were junk, the saddle was junk, it was missing many small parts...well...

    My Nashbar Flatbar E-Bike

    I really like my Jeep Comanche "trekking" E-Bike ( http://endless-sphere.com/forums/viewtopic.php?f=6&t=34102 ) but I found I was using more battery power than I have on some past bikes over the same routes. That limits my assisted range. I didn't want to mess with a good thing so I decided to...

    This is my second effort at building a comfortable commuter e-bike, my first is detailed here; http://endless-sphere.com/forums/viewtopic.php?f=6&t=38759 The Schwinn turned out well enough but it was a tad small for me. I sold the Schwinn after converting it back to original condition then...

    EBay seller claims to have hub motor w/Nuvinci type gearing

    http://www.ebay.com/itm/ws/eBayISAPI.dll?ViewItem&item=270980422365&ssPageName=ADME:X:RTQ:US:1123 It sure looks like my Bafang BPM so I wrote him disputing his claims and he wrote back; Has 8FUN (Bafang) developed a new motor with variable gearing??? -R

    My Schwinn Protocol 1.0 DS E-Bike

    My first three builds have all been refinements of the same basic idea, a 700C/29er with a small front geared motor. I like the present rendition of this formula quite a bit (http://endless-sphere.com/forums/viewtopic.php?f=6&t=34102) but I got the bug to build something different for the fun of...

    My Redline D440 – The 69’er Experiment

    (or "96'er", whatever your preference ) Last fall in search of a bit more comfort I replaced my Raleigh 700C hybrid ebike with a rigid fork with a Jeep Comanche with a steel suspension fork. Wouldn’t you know it though the very day after buying the Jeep I found a nearly new Redline D440 1x8 for...

    My Jeep Comanche E-Bike

    This is my third ebike build and like the previous two follows the same basic formula; a 700C/29er frame with a small geared front motor. My first bike (http://endless-sphere.com/forums/viewtopic.php?f=6&t=8579) simply rode too stiffly on rough rodes and trails, the second...

    High no-load current with MAC (Puma) motor

    Was wondering if anyone has had a problem with unduly high current with a MAC motor? I bought a 500W MAC about a year ago from Cell_man but only just dusted it off to check it out. I have the bare motor set in the dropouts of a bike and hooked up each of the 3 controllers I have, one at a time...

    Anyone have a charger adjustable to the 50.0 to 50.4V range?

    Has anyone checked the voltage range of their "36V" lithium battery charger? I'm most interested in the 4-5A aluminum case models sold by ecitypower/bmsbattery, evassemble and optional from Ping but any widely available charger would be ok as long as it's reasonably priced and adjustable. Can...

    Why oh why did my power consumption skyrocket?

    I used to ride my E-bike and use a fairly low amount of power then I got a 48V LiFePO4 battery and my power use went up 46%. I was already using 48V by running my 36V/6Ah Fatpacks in series with a 12V/9Ah SLA so I didn't jump up in voltage. I always pedal with good effort so I can't understand...

    What is your AVERAGE trip speed?

    I know there are a lot of folks on this board with fast ebikes but how does that fast top speed translate into the average speed for a trip of say 10, 20 or 30 miles? Do folks with fast ebikes get to where they’re going that much faster or are they on the brakes so often their average...

    Last of the snow melts in WI heatwave

    Yes I got back from a ride today and snapped this picture of the last bit of dirty snow in the parking lot melting in 80 degree (27C) temps. That's quite warm for this time of year in Wisconsin and there were lots of people out riding their bikes even in the middle of a week day. -R
