    Painting my bike's rims.

    I got it down that I need to tape up the stainless steel spokes (I think they are stainless, the magnet didn't stick to em) and the axle (Or in this case my geared hub) And prime the rim, then paint it a few coats. Questions: The center of the rim is already black. I can just tape that up and...

    Could I get some ideas?

    I need to get rid of my dérailleur hanger mounted chain tensioner so I can mount the Nuvinci hub's torque arms. I am going to go with a chainstay mounted chain tensioner, problem is my chain stay is rectangular shaped! Can anyone help me out with ideas whether it be a custom bracket to mount...

    Using RC motors as E-Bike motors.

    How is it done? I thought these little RC motors were developed form high RPM? How do folks use them to power heavy E-Bikes+passengers?

    Chain driven electric motors.

    Hey dudes. I was wondering how effective chain driven electric bike motors were. Since I am using a Nuvinci hub and using a front hub motor is not exactly ideal I was thinking this might be an alternative. I am putting money away for a springtime purchase of a motor, controller, and batteries...

    I need some help figuring out gear ratios.

    For 26 X 1.9 / 47-559 / MTB tire with 175 mm cranks with 7-speed Sram 12-14-16-18-21-26-32 Cassette I used a calculator on Sheldon Brown's website and came up with this for my current setup: For 26 X 1.9 / 47-559 / MTB tire with 175 mm cranks and 12 tooth sprocket Now, I don't know much about...

    Bomber forks.

    Which model/year do you recommend for mounting a geared hub motor on? Problem is, I friggin' hate my standard gears/dérailleurs etc. etc. I am having so many issues with them, chain falling off, front dérailleur thing keeps rubbing against the chain, constant adjustment, can't shift into...

    Front Hub Motor with front shocks/disc brakes.

    I know most bikes with front disc brakes aren't comptible with front hub motors because of the space required in the dropout spacing. But I just installed my rear cargo rack and bag, and even empty the back of the bike is heavier than the front. I really want to use a front hub motor to...

    Front disc brake cable.

    So I have yet to secure the cable for my front disc brakes. The cable flops around a bit but not much, do I need to secure it? If so, should I cable tie it to the shock itself, or to the fork itself?

    Tires and hub motors from e-bikes.ca

    How much of a difference do low friction tires make versus mountain bike tires? I have yet to purchase my hub motor/controller/batteries, but for now I will be riding it to work via pedal power. Would I have an easier time if I swapped out the mountain bike tires or should I just leave em...

    Hi dudes.

    Been a while. I was in San Diego for a while, but I am back. Anyway, I have ordered bunches of stuff for my bike. I pretty much have everything before I start saving for my motor, controller, and batteries. But I have a question! I own an Iron Horse Maverick 3.0 with disc brakes. I want a cargo...

    Just got my bike.

    Most of it was already assembled expect for the handlebars, front wheel, and seat. I called up my local bike shop to ask how much it'd cost for them to look at it and make sure I assembled everything ok and they wanted $54.99. frock that noise. I'd rather fiddle with it for a few days before I...

    Do I have pretty much everthing I need?

    My bike is going to be here on Monday. I am bound and determined to learn how to build and maintain a bicycle so I decided to invest in some tools. From reading around online this is what I gathered for tools that I will need. -15&19MM Cone Wrench: $14.15 -Alan Key set # 2, 3, 4, 5, 6, and 10...

    I need some opinions.

    I was going to buy the Iron Horse Maverick 3.0 but I missed the deal on Amazon.com. So now I plan to buy the Maverick 1.5. Problem is I hear the chain is weak, and it has no disc brakes. My question is, Is it possible to swap out the V-brakes for disc breaks and swap out the chain for a more...

    I am freaking paranoid.

    How do batteries/controllers/motors work?

    Well I understand how each single component works but I ran out of space for my thread title to type 'in correlation with each other'. So how do they do it? If you have a 500W motor for instance, hooked up to a 72V/20A controller with a 72V/10Ah battery pack, does that controller draw 20A from...

    I'm looking for something specific for my batteries.

    I was originally going to go with a custom made triangle shaped case to store my batteries in. But I decided I A) Wanted something lighter, B) Something that locked onto the frame and locked the box, and C) Something I could remove to charge. I found this but it's too small to store all the...

    I have a question.

    Is there any advantage to using a LifePO4 over Lithium Polymer besides the fact that it sucks when Lithium Polymers explode?

    Do I have this straight?

    My boss is an electrician and gave me a crash course in electrical properties today. So just to make sure I have this straight I would like to propose this to you folks. I am going to buy the X-504 model. The main reason is here in Northwestern Connecticut there are tons of hills and I need the...

    BionX

    Does anyone use BionX battery packs? I've decided I don't want to build a battery system from scratch on my very first build and I am really interested in going with BionX because of the Sony Manganese Lithium batteries (Thanks Doc, lol). Anyway, I'd like to know how they stack up. As well, I...

    I need suggestions on a bike to use.

    I already have a thread made concerning my setup. But I can't get a clear answer on what type of bike I should use as the base. -X-504 rear mounted Motor -40Ah (72V) Crystalyte Controller -Li-Po 72V/20Ah battery setup I'll be mounting most if not all of the batteries in the center triangle...
