Hi friends,
The three button control on my DPC-14 is acting a bit oddly. To get the UP button to recognize I have to push hard and in a specific location. It's still functional but I wanted to get a replacement and unfortunately Luna is no longer selling them.
It seems a waste to replace...
Range and Speed
I'm coming up on 3000 miles here and the whole experience has been just awesome. I've got quite a bit of time-on-bike and experimenting behind me and I thought I'd share some more thoughts on the range and speed I’m getting.
When I started looking at e-bikes one of the...
Thanks for the follow up with Luna. I think that pack size will fit better in the bike bag they have.
Oops, I meant 48x on both accounts. You're right I have a 48 tooth chainring.
Throttle is independent of the PAS. I did have to change this from what Luna delivered. I've got a post...
I'm not sure why the throttle would matter vs PAS -- watts into motor can be the same regardless. I read that as an indication that most people run WOT which would be like me running max PAS all the time.
Your climb is significant and much steeper than I encounter on any regular basis...
"Insanely helpful" I LOVE it. I learned so much from scouring sites where previous builders had shared their experiences. This blog was a way for me to share back and consolidate information for others. It's always great to hear when someone finds it useful.
I picked the battery pack...
Compare Commute Times and Speed
Two of my main motivations for building my e-bike were to stay cool on my commute into work and to increase the speed. I work in an office and even with just 5 miles I would get warm on the way in. I've got a big fan in my changing room and a small USB fan I...
The Weighting Game
I'm just getting around to posting some pictures of how much the components weigh.
This is the total of what I removed from the bike.
Pedals included in above photo because I replaced them.

PAS Behavior
I wanted to publish some numbers on how my Pedal Assist settings propel the bike with no effort. I went out a few weeks ago and collected some readings. Here was the set up:
I used my middle gear, #5, 48x21 gearing, outside tire diameter is 27.5 inches
Speed limit settings...
Chainline Before&After
I had read a lot about people having trouble with chainline and chain drops. Maybe I was mixing BBSHD and BBS02 threads, or maybe most of the issues were with fat bikes, I guess I'm not sure, but the chainline with my BBS02 on my bike with a 68mm bottom bracket is...
Controller Programming
I'm glad I bought the programming cable. I could see early on that wanted to modify the settings from what was delivered. My priorities were to:
Control the wattage entering the motor to protect it from burnout.
Tweak the power at each PAS level to my liking...
Max PAS torture test
Minnesota posted a pretty nice day today and one of the questions I had is…just how fast can I go and how far can my bike take me at that speed? Time for a torture test.
Here are a few details:
I did this test out in the country on the side of county highways where...
Ride Report
After a month or so of commuting here are my observations (other than this bike is freakin' awesome). :)
Quiet. The motor is almost silent. I rarely even hear it.
Power. I've got it configured to max out at about 750 watts peak (52v*15a) and I find it plenty powerful. At...
My Delivered Luna Controller Programming
I finally hooked up my controller to the computer and thought I'd share the delivered settings from Luna. What I found is different than others have posted as recently as October 2016. From reading up a bit I'm going to need to tweak these a bit to...
