    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?

    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?

    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...

    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...

    Would you please help me diagnose my 48V 15AH Ping V2.5?

    Hi guys, my Ping isn't working. It's seen 200 or so cycles. I reluctantly removed the outer layers of the Ping, opened it up, but I don't see any problems. I'm not sure what to do next. I bought the Ping for plug-and-play, so I'm brand new to this, but I'd appreciate any advice you can give...

    neoprene a good material to protect battery?

    I am thinking about picking this up http://www.amazon.com/Sponge-Neoprene-Adhesive-Thick-Wide/dp/B001G8E114 and gluing it to my ping battery pack to protect it This is expensive, but I want the best material, and I think coroplast isn't durable or soft enough. Is there anything better? Thanks!

    (quick throttle wiring question - no voltmeter to test)

    I did a search (several, actually), but couldn't find info on which wires are which for this throttle: http://www.dapan.com/en/UploadFile/s_2009719174541.jpg The wire colors are yellow, green, blue, and red. I got a controller from ampedbikes that has a throttle connection with red, black...

    Fan in my ping charger died - how to fix?

    Hi guys, Well, the fan in my ping charger finally died. I was fearing this, given how many other people it happened to. I'm not super savvy with electronics, and I was wondering if anybody would be willing to help me, and the rest of the community who surely also will experience this problem...

    some questions for a new build

    keep getting flats at base of tube valve stem!

    Last time this happened, I assumed I just didn't quite align the tube with the rim, and it pulled the valve stem at a weird angle and caused a tear. But I'm sure the last time I made the alignment 100% perfect. I keep getting little tears at the base of the tube stem valve anyway, and it's...

    extra cable length, what to do with it?

    Hi guys, my bike is a mess of cables... power, phase, brake shut-offs, lights, etc. It's really conspicuous. Right now I'm wrapping them around the top tube, but it looks horrible. Does everyone here just cut them down to size and rewire everything? I'd be worried, as I count 12 separate...

    Need to disguise a 9C front wheel

    Hi guys, I absolutely love my 9C front hub, but I need to disguise it. I live in NYC, and twice in the same weekend, cops noticed it, and one harassed me about it and almost confiscated my bike (ping battery and all! :shock: ). I don't really want to go to a smaller hub because I know how...

    best audio system options?

    Hi guys, I want my ebike to bring the party. I want bass. And I want it all powered off my 48v lipo (probably through a 12v dc-dc converter). This looks a little cheap, but I am looking in this direction...

    Will this camera charger work with this LED headlight?

    I want to use my 48V ping to power this 7.4v headlight: http://cgi.ebay.com/MagicShine-LED-Bike-Light-LIGHTHEAD-ONLY_W0QQitemZ270477601195QQcmdZViewItemQQptZCycling_Parts_Accessories?hash=item3ef9b8a9ab Here's the charger (used as a dc-dc converter) I think I'll need to step down 48v to 7.4...

    Which topeak MTX bag will fit a ping?

    I'd like to buy the smallest Topeak MTX bag that will fit either a 20AH 36V or 48V ping battery (V 2.5). Does anyone have both an MTX bag and a ping? I read online that the topeak has an internal divider... it seems like that could get in the way. Is it removable? Thanks! Nate

    Not enough stopping power with cantilevers - try V-brakes?

    Hi everyone, thanks so much for your help so far in getting my bike up and running. I have a trek 820 mountain bike with an amped bikes front hub kit. I am not getting enough stopping power, and I was wondering if it would be worth it to try to convert to a V-brake on the front. If I do this...

    Bad wheel wobble on a new install, as if out of true...

    I've just installed my front ampedbikes kit to my 1997 Trek Mountain Track 820 mountain bike. For some reason, the wheel wobbles significantly as it spins, and I can't quite figure out why. I've tried pushing the wheel firmly into the top of the drop outs, but the same thing is happening. The...
