Hot rodding e-bikes

I think it was John Allen (author of the excellent Street Smarts booklet) who pointed out that until now, there's been at least a rough correlation between a rider's average speed and his skill on the bike. E-bikes destroy that correlation. "Chipped" ones will be worse. I'd suggest these are Darwin Awards candidates, except that such people careening on a e-bike could kill innocent bystanders as well. |

Or cause innocent bicyclists to crash trying to avoid those darn e-bikes. I've seen that happen a number of times on rail-trails around here which is another reason I avoid those rail-trails a lot of times. Some e-bike users seem to think that any off road path or trail is there for them to speed along at the top speed of their e-bike. They seem to EVER consider that maybe someone else is using the trail from the opposite direction. Cheers |

I had been riding my motorcycle and lost something I had strapped to the bike. (I can't now recall what it was.) Anyway, I took the motorcycle back out and rode the same streets and country roads at low speed, maybe 29 - 25 mph, to look for the lost item. And I remember thinking "This is really pleasant." At low speed, there was very little noise from wind or from the engine. I had much more time to look all around and appreciate my surroundings. It felt like there was less risk of crashing. It was quite relaxing. But ever since, with rare exceptions, when riding a motorcycle I've chosen the highest speeds the law would allow. -- - Frank Krygowski |

Why shouldn't e-cyclists do the same :-? -- cheers, John B. |

There's a divide somewhere, for sure. 250W should be enough for most cyclists "who could just use a little help". Even for a cyclist who weighs up to a 100kg, 350W should easily allow a top speed of 25kph on the flat, and plenty of oomph for hills. 500W and even more so 750W just aren't necessary except maybe for dedicated cargo bikes but they could also make better use of available, better gearing choices.

Seems it's easy to modify an e-bike to travel up to about 45 kph. http://cphpost.dk/news/souped-up-ele...tial-accident- waiting-to-happen-authority-says.html Unskilled newbies blasting through traffic at 30 mph? Sure! What could go wrong? Given the amount of plastic in modern cars, it might redress the bicyclist/motorist injury ratios. A 250 watt motor is max legal here,but its possible to buy a 1,000 watt overseas and ship it in. All it requires is wheel buldng skills and deep pockets for the battery. OTOH, we can all hope self immolation is a feature of such activities. |

Perhaps just an exercise program is cheaper than a souped-up e-bike :-) -- cheers, John B. |
