You got me. Didn't think about this issue. :mrgreen: Thats not so a bad idea, we thought about that too. But we only considered upgrading the battery Pack if one ride, for example of a commuter, would take more than 10-20km (6-12miles). But a fully integrated system (PSU+charger+BMS, even if...

THAT... I realized too, just after posting this thread :lol: But anyway, what if we change our opinion and decide to design the whole drive+batt in one piece? (That is still not so clear! Maybe we switch to an all-in-one detachable design after all) Then a device like this would be nice...

Like some of you guys know already, we are a group of students who want (as an economical+engineering project which might be put into reality later) to compile and construct a small, lightweight and easy-to-use drive system. Because of that ist should be attractive to people who hesitated or...

We have also decided different tasks for everybody untill next week: 2 people make marketing, law, cost accounting... 1 battery technology 1 motors (myshelf) 1 construction schemes, drafts 1 sensors and power output adjusting Then next week we will collect, compare and fuse what everybody...

So guys, today we held our meeting, discussing the advantages and disadvantages of the most ideas and we came to a conclusion. We decided to design a mix between go-ped and Kepler's drive...

I wouldn't say that, your post was a very constructive comment. Your answer was logic, you revealed (the not so obvious) weaknesses of the idea, explained their consequences and also made a suggestion which took the good features of both ideas into one reasonable sounding solution. There are...

Just to sum it up: Here all "just-bolt-on" kits I've collected so far. (1) a drive similar to Kepler's (2) something similar, just attached to the seat stay (3) something smaller, like Hidden Power Something like go-ped (I know, the lever ratio and the resulting force is too much, but this...

Nice one, jag! That idea is not bad after all! But we don't have to build it; and we are not going to build it. (Don't know how many times more I have to say this :lol: ) - but I will build it later (as a private person) - I will begin shortly after the completion of this theoretical project.

Wow, another new idea of a variation! And also sounds very reasonable - at least for me. Never thought that there were so many possibilities. @bandaro: Sorry, I cant comment to the viability of your idea, because I have no experience whatsoever yet... I just wanted to say: Isn't it great how...

Oh... thanks for the info you two. @amberwolf Wow, yes, that looks more like it :D

@bandaro: you didn't read my text properly, I said the grey parts (including the battery, motor and conroller) wouldn't move (spin) with the wheel. lol, that looks a little bit like "Tim Taylor"-style ^_^ @miles: Yeah, quite similar: the M.I.T as executing institution, the same idea behind...

Here is one possible way like I ment it: the grey parts are fixed on a plate (I didn't drew the plate, you have to imagine it is there; and all parts are glued onto it or something like that) ant the plate is fixed with the shaft. the red parts can spin.

Ah, now i just saw that jdcburg was faster with the posting :P But I didn't understand all of his words so I'm not sure if my draft hits exactly his explaination... maybe I have to re-read it a few times, that helps in most cases ;-) EDIT: Nah, still don't get what he means with that...

Would be somebody like me ^_^ Your idea has this advantage at least over a normal BB-drive. To my suggestion for the "active+geared derailleur": It was just a fast draft - I drew the drive sprocket too far to the right side of the sheet and too high, I think it is possible to lengthen the...

Hi amberwolf. Thanks for your friendly input the other day. Hopefully I can return the favour: I didn't understand everything you guys spoke of (my technical bicycle vocabulary needs a bit of a polish), but I think I came up with an idea which can save you all the trouble of a lateral-movment...
