look here: http://www.bobtec.de/img/IMG_0304.jpg Motor in the bike (trike in this case), batteries in the one-wheel-Trailer or: http://www.bobtec.de/img/Extrawheel-E-Trailer_FN-Trike.jpg same Trailer, but motor (Crystalyte 406) and batts (53Volt, 16Ah !) in the trailer (wow -> with that...

hey.. what a interesting topic (for me) iam currently trying to build also an push-trailer.. first: i have bought this one: here a pictures: bought it for 45 Euro (there are a lot of this trailers at ebay) its rated: 6kg empty weight 35kg payload possible 16" wheel there are also...

@flecc: thanks for the links for the reviews.. infact, this are not the reviews i meant i made also a error when posting in this thread.. i was mixing it with the " New Tasman bike announced"-Thread however: the review i meant were in German language, testing the new Biketec Flyer-Series...

@Flecc: iam searching and searching and don´t find the review again... in this review there was the Flyer S (the sport-version of the flyers) tested and there he said, that the motor of the Flyer-F Series was bigger, heavier and more quiet the Flyer-S makes a little sing, nothing to bother about

for you maybe this would be the right thing: http://skytaxi.narod.ru/e_rolling.files/image009.jpg here a hires-Picture: http://www.go-one.us/downloads/2.png Go-One³ there are also some videos at youtube (also with electric motors) here the homepage: The go-one³ is one of the most...

hey, looks nice is this the same motor/drive like on the Flyers ? and if so, does it also measure torque or does it measure rpm for assistance level ? and: there are (at least) two kinds of flyer-motors.. the older ones from the Flyer F-SEries (quiet) and the newer ones in the new...

10 Euro --> 18cent for 1kwh from a regular powerplant 10 Euro --> 56 kWh 56kWh <-> 10.000km ====> 560Wh for 100km lets assume he is running 20km/h average -> so he can use 112W per hour average from the 560Wh for the 100km considering the efficience of the drivetrain/motor maybe 70W come...

is there any other kind of meaningfull exercise in itself ? ;) 10 Euro for 10.000km --> thats (for me) the big number which stays in the mind...

ok.. i was too fast with reading: the guy is a (former) football-player.. and i will drive through all "Euro 08 Teilnehmerstaaten".. so all countries, who will play at Euro 08 this year here in Austria (and Switzerland)

here the link i found in another velo-forum: BikeTec - Europa Tour Project bike will be a Flyer from flyer.ch interesting values: the flyer will need about the same amout of energy for 100km like showering for 3min... for the whole distance of over 10.000km there will be electricity of around...

just seen now this thread... for the promised cycle-life: this is true: tested by a hobby college with 8C and 10C continouse discharge current the cell went to about 1000Cycles with a constant loose of capacity (7% after the first 400cycles) ~ 20% after 1000cycles but the innerrestistance and...

when going through my files i found this messurment i made last year with my datalogger (loggs 10 samples/second) just want to share without any purpose i just had 1 nimh and 1 lipo with me, so i used both, looged so i can compare.. i used: LIPO a 2 year old Lithium Polymere batterie...

if you want the features Nicd give you (fast charging, high dischargecurrents, long lifetime, no firerisk like on (many) Lipos, very resistante against deep-discharge,) without some of the dissadvantages (memory effect, high selfdischarging compared to Lipos, heavy for given capacity...

just for the batteries: @flecc: what are "very heavy batteries" in your eyes ? the batts he has mounted are 36V (nominal in real is 33V) 9,2Ah weight should be around 4 - 4,5kg its one of the few bikes that use real good batteries so ;) batteries where you can expect many years of...

here in Vienna there are still running old "Waffenräder" froom WW2 before, during and after WW2 produced by PUCH they are something like cult, cheep to get, single speed here a newer one, from 1958...

yes, you are right.. if NiMh are that better for environment ? isn´t it the way, that Nimh can not be recycled but Nicd can ? i heard somewhere that the mainreason for forbidding Nicd was, that the returns of used Nicd for recycling were so low nicd throughn away --> bad thing nicd...

Nimh-technologie is not that bad as fleccs last posting sounds (discharge-currents, charging-currents) i come from another side (rc-modells).. i remember - about 5years ago ? - when the first NiMh appeared on the szene.. there was said for Sub-C-cells: up to 20A NiMh is good, but for more you...

so.. update.. got the 20" bike today.. the spring at the rear-wheel --> well, does not work very much at all.. so its more for "looking good" than anything else the front-wheel had - out of the box - a little "8" (the wheel is not straight, don´t know how you call this) its not that...

thx.. so i need a Twist-grip + mechanics for a P5 Sram gear hope to find that used in some bike-forum (want to keep the whole project cheap as possible ;) ) for batts: i think i will use 4s5p Konion... have such a pack lying here around, not used until now.. 14,8Volt (right after...
