hi.. the Frame is an old mountainbike, not suspension, steel-fork http://www.kraeuterbutter.at/Bilder2/sonstiges/Mountainbike/Bild02.JPG the axel: yes it is flat, so not completley round why is that from interest ? for the Ring: its not the typical standard "circlip/retainer/snap...

so you mean this is the motor i have.. can you say how these Suzhou Bafang - motor compares to other brands ? i choose it because: 1.) cheap price 2.) Austrian seller 3.) a geard hub-motor, with small size and light weight 4.) free spinning most important for me: 3.) and 4.) so...

ok.. this is how i THINK it has to be wired: considering this plan:

oh: meanwhile i think THIS must be the right direction to mount the rings.. the manual says: "Aufgrund des kurzen Achsradius von nur 4 mm wirken enorme Kräfte von bis zu 10.000 N in Form eines Hebels auf die Gabelaufnahme, daher ist die Montage des geschmiedeten Sicherheitsringes...

hi.. sorry for the late answer, had no time so far... i bought it here: www.specialbikes.at - Tandems - Elektrofahrrad / Umbausatz not Germany, but Austria (were i live) they offer 2 versions: a 180Watt version and a 250Watt Version whats the difference ? both kits have the same...

nevertheless: compared to the weight of a real roadbike still heavy... :( there are no "cool" electric bikes around... even in the high-price sequment (Swiss Flyer, Swizzbee,...) they look not the way that young people would attract. they have the image of "retiree-bikes" and most of them look...

so: another problem: i was send TWO "conversion"-Switches.. but no pedelec-sensor.. have to call the guy... (conversion-switch: its able to drive as an pedelec, or - offroad - in e-bike mode with the hand-throttle alone without pedaling)

and the plan how you have to connect everything... puhh... the strange thing: the connectors do not fit.. there is a connector on the motor with 8 pins (ok, 3 motorwires and 5 sensor i would guess) but on the controller there are 3 seperate wires for the motor (i guess) and...

the controller-unit: if somebody can read this ?!? what does it say ? and how to mount the wheel to the bike: i have no idea if this it he right order to mount it ?!? the ring in the middel is a MUST to be installed, otherwise the fork can break, ....

first the Motor-unit: also it is new it has some cratches and the isolation which holds all wires going into the motor is also damaged a little bit however: it says from the seller at ebay: 180Watt (at 24V) but he told me you can use it up to 50Volt (the controllerunit allows this) then...

hi.. again (after the sparc :rolleyes: ... which still does not run in a bike sofar because one part is missing :mad: ) i have bought an conversion set from ebay.. this time i paid a little bit more (~200 Euro inkl. shipping) for a complete set (except the batteries, will use LiFepo i have...

hey.. was yesterday in a bikeshop: my bottle were the 20cells 18650 fit in, is a 500ml bottle there were also 750ml and from looking at them i bet, that even 30cells fit into this.. so: 36V and 3300mah (or 4800mah when i use the Konion1600cells) with 36V and 4800mah i guess range should be...

i use one of my chargers i already have for rc-modellflying...

hi faphillips: as you i have also two of this BOSCH 36V packs.. different to you, i have the 1100mAh-cells, you have the 1300mAh-cells but the size is 100% identically (18650 standard-cell-size), they also use the same plastic-housing from BOSCH however: i have dismanteled the...

no idea about the law... for the idea: sounds to be a great experiment... at least: without battery this bike would not be fun to drive in my opinion.. on a normal bike you can get eff. of 95% when hitting a hill you shift down and still have an efficience in the 95% region but on...

of course this is not "useful" its an experiment as it says on the video... a experiement is very seldomly useful ;) but it shows prinzips

i was just amazed that it works even on very slow speeds.. so the looses seems to much less i would have thought because otherwise the rear wheel wouldn´t turn

how does it ? here a video not showing it excactly but nevertheless of some kind: YouTube - Eje electrico . 2 Hub motor working as geneartor and motor.

when you have an accident with an moped faster than 65km/h (because it was tuned) (thats the tolerance-limit in austria) and you are the cause for the accident, then - it sounds very distasteful - hope that the child/person you hit dies ! a female classmate from my mother had an accident...

as said: on a serious accident.. you drive through a town, 30mph with your pimped-up-electric-non-legal motor a child comes out between two cars, you have to dodge and because of that cause a serious accident (somebody is SERIOUSLY hurt or even dies) than they will very closley look on...
