Well this was quite helpfull ! https://www.youtube.com/watch?v=UJTMKSuVI3U So i got a better 12g wire in the last days (the other one was splitting just by giving it a little twirl...didn't feel safe; ordered some anderson powerpoles on ebay (30A), and will deal with the waterproof issue...

Help still needed please: So this will be the set up battery in backpack ---> spiral wire coming out of it ----> connection to handle bar (see picture) I'm still wondering what type of connector would be good for the connection on the handlebars, it will be expose to rain and i want to...

Sooo this other part i'm trying to do didn't turn out too well. I want to put a connectors for my power wires. So i went to a big shop in montreal and this is what i ended up putting (they didn't have anderson powerpoles) But in the end, i don't really like the feel of the connectors, and...

Yes indeed, still a pretty good commuter, aint looking for a beast...for now. But i will still put a 52-11 on this bike to reach the max of what my leg can put out (2 rings, 8 cogs)

Hi ES, First of all, great infos here, and great people answering every questions I had, so thanks a lot ! Since I'm a newb in electric in general (never put my hands in wires before but my bike mecanic skills are quite good, so that's a starter). This set up is pretty basic (french here so...

Any one came across one of these ? I would like to order one but can't seem to find it... Thanks !

ok, got news from Paul, a while ago actually, but didn't take the time to come back here to post it: em3ev website: http://em3ev.com/store/index.php?route=common/home -battery pack (BMS not ready yet, so no shipping for now, but it's matter of a few weeks): -from 36V 10Ah, up to 36V 16.5Ah...

thanks, i was under the impression that the drag was more important... so basically, it's quite a good project...not for moutain bike monsters purpose of course...but for regular joe, this is quite something...anyway, the real test will say the rest

As far as i understand electric hubs (newbie here), since this thing can regenerate battery power, does this implies that the hub is DD...meaning that if the battery drop down empty, it makes it difficult to pedal....considering this, the "only one gear thing" makes this bike kind of useless...

thanks for the ABC guys... like i said, always learning :D

I learn every day here but there's one thing i don t understand, if you could help me with this, it would be nice. I understand the concept of the Volt(V) and Amps, but I can t get to understand the "S" and "P"...serie and parallel ? how do you multiply the think and what is the point of having...

Maybe I'm too much use to it but much still need to be done there ! I'm gonna be in Amsterdam in 2 days and THAT is the way to go... ya....32k limit for ebikes...well assisted, after that you can go to the speed "you want"... but since I know someone who have a ebike that goes a 70k-80k a hour...

I've been on this website before but since every battery there was way more bigger then what i wanted i quickly closed my window..(38v20a, 50v, 75v, etc)....it's possible to ask him a specific size ??...lets say 36v12 ah, 38v10Ah...well you get the idea, small sized, not (too) heavy, can make a...
