I am in the process of installing my second Kollmorgen motor on a Currie system. The first one went well on an older Currie but this newest one is different....
... I certainly understand it. However, winding choices only take one so far, and most bikes do not accept radically different rim sizes. ... I just checked it...
... I agree that electric motors, particularly brushless motors, have relatively wide power and efficiency curves. I understand there are official charts of...
... That's my quote - or else someone else charges their batteries the same way that I do. :) I have been using lithium polymer 1000-2000mAh 3 cell packs...
I could imagine 40mile range with a fairing at 30mph on 10ah on a full recumbent-no pedalling(they probably get much more?).But from some of the mile/ah...
Hi Todd Instead of moving the box you can use a switch/relay that Steve Head has been using for a long time successfully.Me and a few others will be using the...
... Hmmm, I would have to build prototypes to see really, but I don't think they would have to be much heavier than any other trike. BUT weight is a red ...
... tim mentioned this problem on his Currie and used washers, another solution would be to use shim stock to get spacing with better thermal contact; I did...
I have always found it wise to replace Tamiya connectors on any electric device that I have used. They start to get hot at 15 amps! Anderson, Deans, Astro Zero...
... Doc is right. Tamiya connectors were designed for toy RC cars that draw 10A or so and they are not suitable for ebikes at all IMO. Anderson connectors are...
Okay so it is a crappy mounting but I uploaded a few pics so you can see what is needed for the circuit. To use your Struthers and Dunn relay it is best to...
I am likely reading this wrong, but I'd think If I was challenged to a race down a hill and I had knowledge such as where to brake to avoid being smeared by a...

But Officer I cannot figure out how you were able to determine I am operating an E-Bike? joshua goldberg evsolutions@... www.evsolutions.net ... From:...
Oh.. and the reason i quoted my test results without pedaling is that it gives a point of reference compared to quoting a range with mostly pedal power.....
... Dan, I do not have any experience with hub motors for bikes but the one hub motor I did try on a full size scooter was not very impresive. I road an E-Max...
Yes, 16" drive wheel. I don't think there is anything special about my 406-409 or controller. I think my performance is what you should expect in any similar...
... I don't recommend that anybody use lithium batteries on e-bikes, although lithium batteries work fine if you know what you are doing and are careful...
... I think so. These hub motors are amazing when you run them in their "sweet spot" (to use and expression I've seen a lot around here lately). Really, at...
... Hmmmm. Either that is an exaggeration, it just SEEMED slow because the E-max is so smooth, or there was something wrong with the E-max. The E-max Sport...
Thanks for the info. It might be possible for me to stick with tamiya since at 48v I'm hoping to mostly stay below 10A on my 408. But I'd like to wire with...
The new batteries powering the Dewalt power tools are available for testing from A123. Has anyone reviewed the specifications for the batteries being offered...
I work for United Nations in Malawi where most people live in small villages connected by dirt roads and bicycles are the biggest investment most families ever...
I commute 33 km each way to work on a EZ-3AL trike, it's the older aluminum model with three 20 inch wheels. Last year I added a Crystalyte 408/412 hub motor...
Thanks Rick for pics and the heads-up on the resistors -sounds heaps better than a converter/voltage tap.Looks like quite a bit of work hooking all those...
Thanks for that Bocabikeguy -it good to know performance and specs of different bike setups as compared to MTB's and such. Do you make much use of the dual...
