    Cargobike project. Very long john from chromo tubing

    AW, you're thinking of a turnbuckle. Turnbuckles allow for proper cable tensioning, and in a well-designed system you can achieve zero play with them. Cable control systems have been used as aircraft primary flight control systems since the very beginning of aviation because they are...

    Broke a 6-32 tap off in an aluminum heat sink, ideas?

    If you have access to nitric acid you can remove it chemically in a few hours as per the attachment.

    Wilderness Energy Misunderstanding

    I've never been a fan of Chinese-made consumer products, in fact I'll scrutinize a label in a store in hopes of finding a U.S.-made alternative. Having said that though, I do have to give the Chinese credit for making great strides in quality control in the 10 years since you bought that bike...

    Smoked Motor on the "Strong" ebike from department store

    Those square black "rods" are the brushes. They're made out of graphite that's similar to the lead in a pencil. The springs ensure that the brushes are held firmly against the commutator for good electrical contact. As long as you didn't toast the windings, you should be able to replace the...

    Christopher, Is yours laced into a 26" wheel?

    MXUS 3000 Hub Motor - V1 V2 V3

    TeslaNV, You wrote previously that MXUS would ship motors with small spoke holes, will the June shipment that you're expecting have the smaller spoke holes? I'm pretty much sold on this motor, and I concede to the argument that the small diameter moto wheels are superior, but I'd really prefer...

    2WD Semi-Recumbent Recycled-Parts Cargo eBike: "CrazyBike2"

    AW, I can tell you with all certainty that they see you. In the last 14 years, I've transported around 6 to 8 bicyclists to trauma centers after they were struck by a car, and all of them were adults. When these wonderful Arizona motorists see a kid on a bike they seem to exercise extreme...

    Not an ebike...but look at this tall frame craziness!

    There's a guy who doesn't buy a brand new bike with each new passing fad... That geometry looks bizarre, but I can see how it would be needed to accommodate someone of his height. He'll probably have that bike until the day he dies.

    KIT I BOUGHT ON EBAY DOESN'T WORK!!!!

    Given that he posted at midnight, perhaps it was a PUI. If so, and if he's read these replies, he could always abandon that user ID, create another, and ask for help again with a fresh approach.

    KIT I BOUGHT ON EBAY DOESN'T WORK!!!!

    Anything can be fixed, but you have to go about it in the right way. First, you should take advantage of the wealth of information already covered here in previous threads, simply by searching the forum for references to the same type hardware that you're having problems with. Chances are...

    The SB Cruiser : Amberwolf's 2WD Heavy Cargo Trike & Dog Carrier

    AW, Have you thought about peening the opening with a hefty hammer to tighten up the clearance? It would not only tighten up the clearance, but it would work-harden the mild steel and make it more resistant to being stripped by the torque on the axle flats.

    Help requested identifying "ampedbikes" hub motor...

    So, after stripping the electrics from the Sino-Schwinn girls bike, I found a suitable frame on Craigslist to serve as a testbed. IMG_0790 by Rick T., on Flickr This vintage, steel-frame Specialized Rockhopper was only $50.00. IMG_0797 by Rick T., on Flickr The dropouts and tabbed washers...

    The SB Cruiser : Amberwolf's 2WD Heavy Cargo Trike & Dog Carrier

    The day after Kody died I was startled to hear Norah howling like a wolf on the back patio. She held a long, sustained note that sounded exactly like the call of a wolf that you would hear on a nature program. Of course she stopped doing it as soon as I had my video camera in hand, and she's...

    The SB Cruiser : Amberwolf's 2WD Heavy Cargo Trike & Dog Carrier

    AW, Great to hear that Tiny is showing some improvement. It took me a week to read all the way through your thread about the house fire, but a thread such as that needs to be read in its entirety. I don't even know what to say, I feel the same way about my dogs that you do about yours. I...

    How to get 12v from 48v battery to run accessories?

    Although a resistor might be more efficient that an over-sized golf cart converter, it certainly won't be more efficient than a small DC to DC converter. That resistor is going to drop 3X the voltage that your led bulbs will use, and waste that energy as heat. A small, low-current switch is...

    Help requested identifying "ampedbikes" hub motor...

    Thanks for the information guys, it pointed me in the right direction to search the forums. I've concluded that a 48v battery paired with a 25 amp (limiting) controller should be a reasonable configuration. Given that the motor is wound more for speed than torque, plus my commute is hilly and...

    Thanks for the info DDK, I'll research the 9c to get some idea of this motor's capabilities.

    Help requested identifying "ampedbikes" hub motor...

    Greetings to all, I've had an interest in electric bikes for several years, but procrastinated on acquiring anything until the last few weeks, when two deals came along on Craigslist that seemed to offer a lot of value for the money. The first was a pristine 24v EVG e-bike for $50. It lacked...
