    new eZip motor

    It goes on and on. Curtis, you are weak on technical, so please listen to the advice they give. Yeah, sure. You can probably run your bike on just the batteries and a switch. You will burn out many switches in a hurry, they are not for high current. That would require a starter solenoid...

    The King of Mid-Drive Batteries

    So, a fire can be avoided with very careful monitoring. A fire in the neighborhood of my crotch. It does not sound like a kingly ride to me.

    Which rear-geared-drive for bike that has 8 rear speeds?

    We know they are not as tough as Shimano, that's understood. But a great many folks use them on their bikes with adequate results. It's a compromise, because Shimano does not make 8 or 9 speed freewheels, nor 11T cogs, which we would rather have but can't. For a high powered bike, I would of...

    Which rear-geared-drive for bike that has 8 rear speeds?

    If you want to keep your cassette, use any hub motor with a freehub. Freehub motors are not as common as freewheel motors, and they cost a lot more. Alternatively, you can use an 8 speed freewheel and the more common freewheel hubs. You find them on Amazon or eBay for about $35. Because...

    Speedo freakout while pedaling with PAS

    Disconnect the PAS or speedometer input from your controller. They are somehow connected, and you need only one or the other, no?

    20" vs 26" bike wheel, what's best?

    I notice all the homeless types here seem to cruise around on mountain bikes. Maybe they will get new used ones for XMAS. My fav is the guy with a kiddie trailer for his dog. They go everywhere, and the dog seems to like life on the road. Hope they are warm this year... It's a tough life.

    20" vs 26" bike wheel, what's best?

    It sounded odd to me. It was Rick the owner, too. Maybe they just want to sell me a whole bike if a part breaks, huh? No matter, I just tore into a junker and got what I needed. I'm new at this, but it's fun to put stuff back on the road, err, trail. I can see why Freehubs are sturdier...

    California: AB-1096 to classify an "electric bicycle"

    Shimano and SRAM have wireless communication already from shift levers to derailleurs. Who would notice a stealthy thumb throttle that was wireless? Make it appear to operate a mechanical bell and few could tell.

    20" vs 26" bike wheel, what's best?

    Today I changed a solid 10mm axle that was bent. I guess the good news is it did not break. But it was bent so bad the bearings were binding. I thought it was the brakes dragging, but no, bent axle. This was on a full suspension mountain bike that I suppose did its fair share of potholes and...

    20" vs 26" bike wheel, what's best?

    Really? I have to disagree. Chalo is totally correct. He makes these blunt pronouncements, but he's been correct every time. Voice of Experience. "..20 inch wheels have a much harsher ride, more rolling resistance, less traction, and accelerated wear characteristics compared to 26 inch...

    Charge phone off hall sensor power?

    Hook the thermal switch to your ignition switch input on the controller. That should turn off the controller on overheating.

    Charge phone off hall sensor power?

    New chargers don't have a 60hz transformer, so no short. They rectify the AC, then convert the DC to some lower voltage using 100khz magnetics in a tiny converter. Typically rectified AC is 168v peak, but a DC-DC converter may work OK on lower voltage, like 48v DC. Some will have undervoltage...

    How to adapt motor to chain drive? Suggestions welcome!

    You are wasting your efforts. This motor needs to run very fast to develop much power and to turn its fan for cooling, like 2400 RPM. It will burn up quickly when used on a bike, at 60 RPM, unless you reduce the RPM by 25:1 using gears, and even then it may not last long. You need a motor...

    Charge phone off hall sensor power?

    Probably not a great idea, there is probably not enough current. You could easily screw up the operation of the motor if you overload the sensor supply. There are very cheap converters on ebay that will hack your battery voltage of up to 60v down to 5V...

    Old unknown Ebike - Restoration/Upgrade

    About your problem getting the new BB to fit the existing bike BB threads, there are some cases where the chinese changed the thread to metric from inch. They went to 1mm thread pitch, about 25.4 threads per inch, and made the BB cups to match. As long as you use a similar thread, all is well...

    Cyclone kit suddenly failed? Throttle or controller..?

    You could have wiring or connection problems, that is more likely, double check them all. But let's assume it's a bad FET. FETs are not easy to fully test on a DMM, and you are unlikely to have a more advanced semiconductor tester. You can make simple tests for shorts and opens. You need...

    500w, Dayton 24V DC Gear Motor MY1020 setup

    electric fence module used for anti-theft device.

    Use a tazer for the charge, and connect to either the grips or put two contacts on the saddle. Brings new meaning to the term electric bike.

    new eZip motor

    The Stealth Bomber bike, probably the most powerful commercial bike, uses a 72v 20Ah lithium phosphate battery. A replacement battery costs about $2300. It is not likely that one ten times larger would be physically practical, not to mention it would cost more than many cars.

    Is there room for a new electric bicycle company in the US?

    Actually, their Itunes revenue is the flywheel that keeps apple alive. For hardware products they depend on new gadgets, but the market is saturated. I suppose apple loyalists with flock to buy the latest upgrade, but China is making a lot of $100 clones now, how long will it last? Their...

    Secure triangle battery pack

    A determined thief can steal anything. There is a Dawes bike frame for sale on my local Craig's List right now. Nice frame. The owner chained the complete bike outside overnight. By morning, the wheels, brakes, shifters, forks were stolen; the frame was bare except for the chain. Take the...

    Battery performance dropped off in 2013 Stealth Bomber

    I don't even know the chemistry or construction of your battery, so I looked online. "72 volt / 20 ah / 1440 wh Lithium Phosphate" Right away, we see this is a custom battery for your $10,000 bike. You are unlikely to find a standard cheap battery to replace it. It is possible to examine...

    Factory Longtail Cargobikes (17 so far)

    Seen on Craigslist, said to be a Virtue Cargo Bicycle. I have no idea who really makes it but there is a Virtue Cycle company in San Diego, though this is not in their catalog. The forward weight does not affect steering, since it is mounted to the frame. But how do you get on the seat? I...
