    Surly E•D•LHT - Touring eBike Build with BBSHD!

    Nice job on the EDLHT! Still liking it? Any change in your range/battery capacity yet? I was curious about the insurance you mentioned - what provider did you use? Thanks

    GRIN baserunner with "shark" pack that has no controller case like EM3EV's?

    That's a good point, thanks -- I think the best place is probably on the top of the downtube near the headtube. There might be just enough space beyond the front of the battery pack if I mount the battery pack on the bottom tube right at the junction with the seattube. The bracket doesn't seem...

    GRIN baserunner with "shark" pack that has no controller case like EM3EV's?

    Thanks Amberwolf. After a lot of sleuthing, I found out it's designed to fit on the front fork caliper brake bolt, to mount the controller just above the front fender, below the downtube. Kind of a funny place. It's designed for a specific conversion of Brompton bikes as shown below. So, that...

    GRIN baserunner with "shark" pack that has no controller case like EM3EV's?

    Grin sent me photos of a bracket they'll have available eventually. I'm not sure what it attaches to or how. I've asked them but they're pretty busy.

    GRIN baserunner with "shark" pack that has no controller case like EM3EV's?

    Ok thanks - very helpful amberwolf, my order hasn't shipped yet so I just emailed GRIN to see if they'll let me pay the difference for the phaserunner.

    GRIN baserunner with "shark" pack that has no controller case like EM3EV's?

    Thank you both! I didn't even realize those plastic controller cases were a thing -- ebikes have really picked up since I built my first one 15 years ago, interesting that there's now those kinds of accessories. I'll look into finding a small one.

    GRIN baserunner with "shark" pack that has no controller case like EM3EV's?

    Thanks Amberwolf. I'm going to be running a 8T GMAC off a L10 baserunner in a 26" wheel on a KHS pro soft-tail bike, with a EM3EV super shark 17AH 52V pack. Notably I will also be running a CA3. I have a big full triangle on the frame for the battery with room to spare, so I guess I can just...

    GRIN baserunner with "shark" pack that has no controller case like EM3EV's?

    Thanks - I'm curious where people are putting the baserunner when it's not in the battery housing. A phaserunner is designed to attach to something like the seat-tube, but it looks like the baserunner would just kind of hang out... I don't want it flopping around so any tips for housing it would...

    em3ev Super Shark Wake up Battery?

    Where's the photo? I want to ride there!

    GRIN baserunner with "shark" pack that has no controller case like EM3EV's?

    I searched but didn't find quite what I was looking for. Has anyone used a GRIN baserunner with a shark-style battery pack that has no controller case in the slider? I'm wondering if the phaserunner would be preferable in such a configuration, as the baserunner seems like it wouldn't integrate...

    minimizing required maintenance - tips with or alternatives to mountain bike suspension systems?

    Thanks for the feedback! Glad to hear that my experience (and preferences) probably aren't typical. Good points, I just mean speed and time in the saddle as being the unusual parts of ebiking vs mountain biking. The lowers somehow got damaged, but I never crashed... before the pandemic I...

    minimizing required maintenance - tips with or alternatives to mountain bike suspension systems?

    I'm interested in a new build. I rode a KHS softtail with a 9C fed 2k watts for years, but gave up out of frustration from constant maintenance issues, mostly non-ebike mechanical things. For me I've hated constantly replacing disc brake pads, this has been discussed a lot and seems like you can...

    Controller upgrade candidates for a 9C hub?

    Thanks, edited post to reflect Washington, DC location.

    Controller upgrade candidates for a 9C hub?

    I am running a 20amp controller with a 9C-type hub in a 26 inch wheel, using a 50V 12AH battery with samsung 25R cells (so I can give it more amps if I want). It feels very sluggish, so I think a more powerful controller will help. I have extremely beefy torque arms, but want something...

    FalconEV 19" triangle bag.

    Old thread, I know, but FYI I have both the falcon EV bag and the em3ev bag, and the EM3EV bag is smaller by quite a bit. I prefer the EM3EV bag, but probably just due to its bigger size. The velcro straps also seem more flexible. The straps on the EM3EV bag might be able to hold as much...

    I should've read this forum before I bought my battery from sun-

    Actually, I did extensive diagnostics, I just didn't type it out on the forum.

    will a front wheel drive be safe on a carbon fiber bike?

    I agree with the folks above. A light carbon road bike makes a not very good e-bike. In building and riding a couple different ebikes over the years, it didn't take me long to view disc brakes as one of the most important features, for one thing. A suspension front fork is also right up there...

    My experience with Sun-thing28

    Dnmun, what would you have advised, beyond what I've already described trying. I'm trying to be fair and open minded and respect your opinion. Thanks

    My experience with Sun-thing28

    Dnmun, your assumptions are spectacular. Naturally, extended time left on the charger was my first approach, of many, including various discharge cycles. This is not my first battery. I've been nursing LiFePo4 packs for years and years.

    My experience with Sun-thing28

    Hi Dnmun. Thanks in large part to help you have given me in the past (and I thank you for that) I know my way around a battery pack. Your implication is that I should be happy to do surgery on a brand new item (which I actually did do) and spend more time taking pictures, typing measurements...

    My experience with Sun-thing28

    Background on me -- Been a member for several years. I have two ebikes. I used 2 ping batteries until they both finally died. I fixed each multiple times, getting replacement cell groups from Ping and hacking up the packs and reassembling. When I had had enough of that, I bought a 48V 20AH...

    Retiring my first LiFePo4 pack

    Thanks Dnmun. Do you rebuild your packs from these cells using your own connectors/compression? Probably no way to reuse the ping architecture huh... I'm considering just mailing them to you and shelling out for a new battery from somewhere.

    Retiring my first LiFePo4 pack

    I have 2 48v 15AH ping packs. They lasted me 2 and 4 years respectively, but maybe only 150 to 250 cycles on each. I'm sure I didn't discharge them too quickly or too deeply either. Each has a couple bad cell groups but plenty of good groups between the 2 packs to reassemble into a single...

    Sunthing battery 48V 15Ah

    Hi Overtonmath - would you mind giving us an update on your battery? Are you continuing to get about 700wh out of it?
