I dig the new e-scoots. All that torque is available at a very low rpm. Cost of batteries is still the biggest barrier to success in the e-scoot arena. Until we get a breakthrough in battery chemistry, e-scoots will not be very affordable to the masses. I really like e-bicycles, because you can pedal to extend your range.    |

I would love to have one of those, you don't even need a parking space for that thing!  |

You might be able to take the folding e-scooter on the commuter trains. Store it inside when you get to work. |

I like that GENZE from Mahindra too (especially with this driver). The open top cargo area bugs me, though. I would need at least a net over that cargo area on our bouncy Houston streets.  |

The e-bikes are really easy to fix, only a few components really. Battery, controller, motor, throttle and a brake or two and you have a fully working e-bike. The only thing that bugs me is the low distance unless it is a pedal e-bike then it is a different story. I would easily get stranded on a pedal-less e-bike haha I travel about 20-50 miles a day depending on what I'm doing.
The new foldable e-bikes look like retro transformers lol.

i like the idea,,but battery life and range are issues at least for me,,,and i'd like the idea even better with some kind of solar charge arrangement like foldable panels that could be deployed for quick charging while you were at work or any time its parked in the daytime so youre always "topped up",,,i think a hybrid arrangement is best for right now,,,a very small 25-30cc engine to run a generator so it's always being charged ,,,kinda like a train locomotive

Just be careful not to scratch it cuz you can't get a paint job. |

Just be careful not to scratch it cuz you can't get a paint job. Unfortunately, solar panels have to all be in the light to work properly, any panel in shade throws off the entire system. This can be worked around with lots of extra electronics, but even then the efficiency drops by huge amounts, and the price skyrockets. This is why electric cars are not covered in panels yet. |

But what if they didn't chain together the solar panels and instead hooked them up so they would be one-way and would all independently be providing power to the battery and engine? I mean we can do it in small scale projects like for portable solar chargers so why not with vehicles? |

But what if they didn't chain together the solar panels and instead hooked them up so they would be one-way and would all independently be providing power to the battery and engine? I mean we can do it in small scale projects like for portable solar chargers so why not with vehicles? Depends on how much power you need. Hook them up in parallel, get the panel area that's facing directly at the sun in square meters x 1,000 watts x .22 efficiency ( see here for details) and you have the wattage for a sunny place like Arizona. (Deduct a percentage of the watts if panels are not directly facing the sun.) So if you had one square meter of cells, that's 220 watts in best conditions. With 10 hours of direct sun, (which won't happen unless the cells can rotate with the sun) that's around 2200 watt/hrs. per day of available power, or 2.2 KWH per square meter of cells directly facing the sun at 22% efficiency in 10 hours or .22 kwh per hour. The battery on the unit at the top of the page is 1.6 kwh. It would take a little over 7 hours to charge that bike and go another 30 miles or so. You can double check the math in case I made a goof. |

I think range and lack of charging stations make them for short commutes only. I wonder how heavy they are, most electric motorcycles are pretty heavy for the performance you get. Price and dealer service as well as aftermarket replacement parts might make them like Tesla, for the wealthy in major cities. The hybrid idea like Spandi mentions makes sense but give me at least 49 cc engine

Somewhat related: Wunderlich has added an electric front hub motor to a BMW dual purpose motorcycle for an on-demand all wheel drive system. They are not offering a kit for sale - yet. LiPo batteries mount behind the headlight. I'd post a pic, but IMG links from gizmag will not display for me. www.gizmag.com/wunderlich-electric-2wd-bmw-r1200gs/40558/ |
