Do you want to see THE WORLD'S SIMPLEST TRANSMISSION for Bicycle?Watch: UNIQUE BIKE CRANK ( 2- SPEED)

hutzbe to even call it similar to davinci, what moron put up this name...

Not a novelty, for bikes, but the problem is weight. See to ride a bike at maximum efficiency you should ideally pedal at a set speed and decrease or increase your moving speed by changing gear. EG spin your pedals at 1.5 times per second and change gear to change bike speed. This is the most efficient way to ride a bike and racing cyclists would love it. The downside is that if the thing weighs 4 kg it is too heavy for a bicycle.

There was oil leaks problems with the first bacthes, but the manufacturer seems to have replaced the problematic units, and in the new ones don't seem to have this problem anymore.Also, it is impossible to service it. It is sealed for life with an guarantee of 6 years (and from reviews it seems that it will last an lifetime for regular use)
Caroliano(November 30, 1999 at 12:00 am)
It does not seem *horribly* inefficient, and I have seen at least two long term reviews in this thing. One using it with lower gearing than advised by the manufacturer, and pushing 2 kids for more than 10.000km in the space of 1.5 years. No maintence, and the hub aparently feels as new.It was definitly over enginereed, to suport up to 5kw of potency.
Caroliano(November 30, 1999 at 12:00 am)
It is quite easy to find this information.. Anyway, the weigth is ~4KG (competing hub gears are 1~2kg); it seems to be ultra-durable, even puting 1kw of eletric power in it; it is impossible to service, sealed for life with an 6 year guarantee; the manufacturer will not disclose the efficiency, but at the same time it don't seems to be too low. Probably at the low's 80%s. That may be compensated by your legs/motor working always at it's peak eficiency, so not that of a big deal.

I mean this in the nicest way, but if you're going to be unnecessarily verbose, at least proof-read before posting, so you don't come off as some half-literate windbag trying to sound impressive while pointing out the obvious. Also, I'm not inferring anything. This isn't the right situation in which to use the phrase "If you're going to infer..." If you think back to the coffeeshop/party/tvshow where you heard someone say that, you'll see that that situation was QUITE different from this one.

@PRIMEx420I mean this in the nicest of ways, but if you're going to infer that there's wear, then you're inferring it's a real word system. Of course it's going to wear, everything does. If it was JUST metal on metal, it'd wear out QUIET fast in comparison.

@fordtaurus1996 the real question is, how much does that thing weigh! |
