Reports from Eurobike 2011

[Miles]

Thanks Jules!

The motorised Pinion looks interesting... but heavy...

Yes, I've spent a bit of time talking with him and looking his HTfiber frame and jackshaft drive....really interesting...

The motorised Pinion Is heavy and, with their tipical timetable, maybe a 2 yearsbefore to see any kind of production is needed....and cause the gearbox price, is around 700Euro (OEM), don't want to know the price for this...
I have a plastic version of the gearbox they give me for a frame build.....for a full susp, compared to a complete XTR, the price is not so far....but the weight...

What I found interesting during the trip about Electrics (remember that I'm a newbe for most of this world....):

Bosch System in many interpretation. (In Berlin some guys has haked it via software+some little Hardware replacements for more than 4x the power...)

Cleanmobile coaxial motor....a net design....but with big diameter and heavy...

Interesting pushertrailers also with RPM Crank pedelec sensors.

A lot of battery case models from frame incorporated through bottle-style to Hub-included.....also I've found a good source for Japan Li-Mn batteries I think...

From my side A lot of interest on our wheels....eheh, a rear 29 complete wheel with sapim spokes and a beautiful handmade Dugast tubular.....

Last Gruber is now really noiseless....

You can hear how quiet it is, on the video here (my presumption): http://www.bikeradar.com/news/article/e ... deo--31554

Nice wheel!

[Miles]

Apart from the Pinion, there's nothing that I haven't seen before..... There's certainly a lot more of the same, though.

Thanks for all the pics, Jules!

Hope Other members can Enjoy the pics too.....I know it's hard to surprise you, Miles

Have a nice time....

What's this one, Jules?

[Miles]

The Pinion certainly looks the biz...

The Pinion certainly looks the biz...

..until we find out what the $$ is

The non-motorised version, at 700 euros, isn't excessively expensive - compared to the Rohloff....

The "smart" bike, is well, smart

Expected Specs for the future pinion motorGB

Maybe from these other wiew-angle.....

[TylerDurden]

^^^ Does it fit on typical frames under the existing BB?

[panurge]

Inside the Achiever stand on a table there was this non-coaxial version of their system......
I ask for Info and they was a bit nebulous....it's the pedelc kit that yes, fit on standard BB.....also last year they have a non-coaxial pedelec system...Specs are the same I think: 250-350 (24-36v) and 40Nm torque, in around 5 Kg with chain or belt wheel....you can see that the crank/sensor is identical to the coaxial one (see achiever pics sent before)

Expected Specs for the future pinion motorGB

Thanks for that!
800W, 8 gears, 4.6kg is actually very good. Wonder if the crank arms are included in the weight.

Not, Crank arms are not included and they are 364g, the shifter is 115g, only the 24t/30t sprocket is included in the 2700/4600grams. (normal/motorised)

I'm starting to catch on to bike terminology. Cargo = bikes for fat arses.

Quite strange...

Hagen infinitely variable chain wheel.

A transmission for bicycles and the like which includes a plurality of radially displaceable sprocket members with means for controlling the radial position of these sprockets members which positioning means includes a pair of plate members having reversed, identically curved paths thereon with the sprocket members mounted at the junction of the paths with means for controlling the relative speed between the two plates whereby the paths will be shifted with respect to one another and their junction point will increase or decrease radially thus moving the sprocket radially inwardly or outwardly.

Discussed in Bicycling Science Whitt & Wilson 1974 page 147.

No doubt Miles can find a 19th Century example!

There was the "Protean" expanding chainwheel of 1894.

Or the "Paradox" by WD Wansbrough, which appeared in 1901. This could be expanded or contracted in one tooth segments, from 20t to 26t (1" chain...).

Wansbrough patent:
