    Q: Best way to get low voltage, high current controller?

    So I have a fast wound motor laced in a big wheel. (Big no no...) And at 48V 15A , it sucks to the point of non-use. Since what is past is past, I want to find a suitable controller for this poorly leveraged motor. (let's not get into how bad a decision this was to lace it in a big wheel or why...

    Oregon Manifest bike designs

    I saw this site for a design contest with some cool bikes. One entry is an electric bike. I picked it as my favorite before even knowing it was the electric one. The built in lock is sweet. What you guys think? Which one would you vote for? Which one would you convert...

    Cal3thousand's Norco VPS Six - HT3525

    My bike is currently in pieces for a major upgrade, so I thought I would finally take the time to write something about it and share it. Current Photo: This is my first attempt at a full suspension bike. I've only owned rigid bikes in my lifetime since real mountain bike riding was never my...

    Xtracycle Edgerunner - Mid Drive build log

    Although this is far from my first build, it is the first time I will be logging progress as I go along. Usually, I keep notes in Evernote that never make the light of day. There aren't enough cargo bikes on this site, so I thought it would be nice to have some more content up. Frame: I...

    Cargo bike film: Backers needed. That means you fellow biker

    This is a very cool project film: Less Car, More Go. A Cargo bike documentary. They just need backers to reach their 1,000 backer goal. Any amount will do, chip just a buck ($1) if you can spare. This will help a family in need, get a free cargo bike so they can make the switch to being...

    i hate you all (tongue in cheek)

    At 48V the MAC will be the funner ride. Especially if you get the right winding. I would say 8T would be great for you. If you use a real 48V, it will get you around 28 mph and get you there quickly. It jumps from the line on just 48V and pulls up hills hard. The HT/HS are really only fun (IMO)...

    Giant Stiletto Chopper Project - Throwing around ideas

    I have a Giant Stiletto "Chopper" style bike that I picked up for cheap and want to build up and sell. I'd like to make it a fairly quick turnaround and not get too complicated ( I have a tendency to do that and this bike is not for me, I need to keep that in mind). If I were to keep it, mid...

    I just lucked upon this front Phoenix Brute aka 5305 aka huge, power capable anchor Basically got it for the price of a long drive through Hollywood in traffic (I paid some pocket cash but that's literally nothing compared to the agony of that drive ). He was going to chuck it and it was...

    HT3525 Cogging observation - Xlyte axle wire cut issue

    The Story: I have a Crytalyte HT3525 that I purchased from Methods and laced into a 26" wheel. From the moment it was laced and during truing, I noticed that this motor cogged A LOT. Having no previous experience with Xlytes, I did some reading and noticed that cogging was fairly high on this...

    OneWheel: self-balancing e-skate

    OneWheel seems like a really cool idea. Anyone here seen it or heard of it? Quick thoughts: brushless DD motor Lithium battery gyroscopes for forward, brake and reverse. weighs 215 lbs :shock: Seems like it would be a really fun ride and could cover terrain that other e-skateboards...

    Show me your camera setup!

    There are some pretty good videos here on ES and then there are the not-as-nice videos as well. We are videoing our bikes, commutes, maintenance etc, but we don't discuss our shooting equipment or technique that much. I wanted to get a discussion (in depth) where we can collectively gain some...

    Are there any Mid Drive Fat Bikes?

    I've been interested in the fat bike phenomenon lately. Now a fat bike is fun on sand and snow, but not without a motor. But I also want to play around with a mid-drive setup. Would it be more or less reliable than a hub motor in snow or sand? If you laid the bike down and got sand in the...

    Damn Thieves!!! - They came back AGAIN!

    Just a rant... So, I have been getting reports from other neighbors in my building about some lurkers that have been eyeing our bikes and things in the carport area recently. I even saw a couple guys on bikes scoping out the joint and walked out to talk to them last week. Needless to say, they...

    New Wheel building Calculator

    I've been using http://leonard.io/edd/ (previously called: http://lenni.info/edd/) for calculating the spoke lengths on my wheel builds with much success. Every spoke I have needed has been perfectly calculated. But yesterday, I was on the Xtracycle Facebook page (trying to order one of the...

    Super bright, high current LEDs on the horizon

    Research at my Alma Mater has preliminarily discovered the reason for LED inefficiency at high current levels. This was holding back even brighter LED packages that will be able to replace CFLs as our most efficient lighting technology. To summarize, they found that LEDs at high current suffer...

    Help with brake light circuit needed - LEDs

    I have a couple sets of 12V led strings from car projects that I would like to use for brake lights. They are waterproof, 12V, led and can be daisy chained. Currently, the bike in question, has hydraulic e-brake levers that complete a circuit when the brake is squeezed. They are wired to the...

    MAC 7T Hall's busted, replaced x2 , removed PCB, video incl.

    BUSTED: So on the very last leg of my wife's long overdue bike build, I plugged the CA-DP wire into the Hall connector of the motor accidentally. Yes, I know the controller has a 6 pin JST and a hall should only have 5. But on this motor, a temp sensor has been installed by the factory and...

    Wife's iZip Zuma stolen yesterday

    Some asshole stole my wife's bike last night, her sole form of transport. At least they were nice enough to detach my daughter's trailer and leave that behind. :evil: Had it locked using a thick ass MasterLock, but they busted that. Just looked at the paperwork for claiming a loss against...

    [Challenge] For those near LA, I have a hill for you

    Just found this hill after watching a youtube on Hi Power Cycles. They took a 8kW 2WD up this 33.3% hill. Supposedly this is the steepest hill in the western US: http://www.walkinginla.com/2004/Feb15/EldredSt.html I've determined that I need to conquer this hill with my DH rig once it's done...

    Suspension and Noise Damping

    Last night I installed a new front fork (Rock Shox XC32TK 100mm) on my commuter bike. I paired it up with a wheel that I recently built (Alex Adventurer 700c / Shimano M529 6-bolt) and a 180mm hydraulic caliper (Tektro Auriga Comp). Things that I have noticed in the change over: The suspension...

    An often overlooked part of hub motor choice: Hub symmetry

    After dishing my first (self-laced) hub motor (MAC 7T in 26" Alex DM24) , I noticed that the tensions required to keep this hub dished properly were nearly 2:1 with higher tension on the drive side. This makes for a wheel that is not as durable as a symmetrically dished wheel. My next motor to...
