OT My third electric bike
Took so long to make.
This might be the easiest to build electric bike there is, versus power and reliability. https://www.flickr.com/photos/27532210@N04/ Front 18" wheel direct drive, using DeWalt's DCD961 brushless drill. The fork is standard, so it can be put on any small bicycle frame. Functionally not much different than a hub motor, but there are probably significant differences in performance (what exactly, I do not know). The speed switch is intact, so I can play around with that. It is meant to be on the lowest speed setting, should be fast enough. This design has been tested, but the prior version was not nearly as efficient. Then, it drove a chain that drove the rear wheel. All that is unnecessary given a drift trike front wheel with a pedal hub (without the pedals) and a low-geared cordless drill at no more than about 450 RPM (no load). The drill kit cost about $280. Depending on your application, extra batteries might be required. The drift trike front wheel (an adult "Big Wheel") costs about $150-$200. Seems overpriced, but oh well. Difficult to find many replacement parts for drift trikes. Seems they enjoy it in Australia. Mad Max on a Big Wheel. |

Oh yeah, the (lack of) work involved...
Could not be easier. Use a rotary tool to slice off the end of a 1/2 inch drive socket. Cut to wide pieces of aluminum flat bar and drill holes through them. Stick them to the bicycle fork. Then just connect a speed controller from the bicycle's handlebars to the drill trigger. A cheap Shimano Revo shifter works great for throttle control, after opening it up and removing the internal latches. The drill trigger is depressed by simply anchoring a bicycle cable noodle to the trigger and the drill handle. When the cable is pulled, it pulls the trigger towards the drill handle. I will post a pic or two of that when it is stuck on there. Not sure whether I will put the fork plus wheel on my current 20 inch BMX bike, or whether to make an ultralight vehicle out of another aluminum bicycle frame. |

For that price you can buy 2 wheels with hub motors that will fit standard forks - and not have the fuggly and heavy drill-motor hanging off the side - and it will actually RUN. When you say it has been tested, how does it handle 200 lbs on a 5% grade? How fast does it go? (and how far?) And you can NOT coast with it. Totally useless setup in my opinion. (and I ride an electric bike and have built one - neither of which uses a hub motor) |

The only one I ever got up close to had basically a unicycle wheek - - a "Fixie" adult big-wheel - The rest of my critique stands. |

It is also almost invisible when driving down the road and has a range of about 15 miles. on a frame mounted lead acid battery pack. |

Put it on my BMX bike. It goes ZOOM.
Similar to the second bike experience, but more efficient and much simpler. A 20 inch drift trike wheel will probably work fine. -- I wrote: Took so long to make.
