"when u build it, they will come" ;) im a former application developer, i wont promise too much cause it makes me sick (no joke, burned out a few years ago, get depressive and had to quit my job to save my soul), i promised myself to not dive into coding too deep again, but im willing to do...

actually im unfortunatly out of funds, otherwise i would have bought it. its only a few hours away, so transportation is manageable. if its still there till end of next month and i can afford it, i ll get it.

rc controllers are known in general to blew up when used in e-bikes. the castle creations seems to last longer and they have a flat replacement fee. afaik almost every turnigy esc used in this forum is blown quite quick. a slipper clutch may help to prevent it from blewing too fast. also u...

its not categorical valid for hole europe but especially for the netherlands, bikes are part of their culture and lifestyle. its absolutely flat and its a small country, its all compressed, there are no long distances in the netherlands. i know the design looks familiar, first i tought on this...

the thread opener is located in the netherlands, a country where cyclin is mainstream, suv drivers are the minority there and they are all aware of low and fast vehicles like recumbents, there are a lot of them, propably more than anywhere else in the world. so i think drivin there with this...

financially is not ur problem, technically i think there were some developments in the last 20 years. what about a rc setup, lot of lipo or lifepo, add an differential ... . i think theres a lot of room for improvements. whats the reason for cornering problems? where were the batteries located...

ive never seen this thing before, looks awesome. for 250 euro dont ask, buy. if it turns out it doesnt fit ur needs than sell it maybe with profit. how does it work? rear tires driven? is there a differential or is only one side powered? what about the handlebar? do u put ur legs above or is it...

i totally agree with u. what i want to mention is, that there is the possibility for faster, more powerful ebikes in europe. called s-pedelec, its restricted to 1000w max, 25 km/h without and 45 km/h with pedalling. but ur not able to build one by yourself except u have ur personal lawyer, a...

exactly thats the point. but im sure they will release a higher power version for s-pedelec when they find reliable partners. the problem with s-pedelecs is that u have to have certification for every single part that its save for 45 km/h use + certification that the whole bike assembly is save...

if its a standard metric thread u can figure out the pitch according to diameter with this chart http://www.gewinde-normen.de/en/iso-coarse-thread.html

when u have a close look at the pictures its quite easy to backtrack :wink: manufacturer: http://yiyun.cn/Product_Detail.asp?ID=109 dealers: http://www.tncscooters.com/YK43B.php http://cgi.ebay.com.sg/NEW-24-60-Volt-Controller-Model-YK43B-/330424800950?pt=LH_DefaultDomain_0

u dont know anything about particle physics right? ever heard of heisenberg? on a subatomar level its always "or". dont take me to serious, im just kiddin. im an atheist believing in the laws of thermodynamic. but keep on doin ur missionary work, maybe im wrong. :D

u cant add that, its an 123mm axle inside a 72mm tube. final width would be axlelength - 2 x crankwidth at bottom + 2 x offset. i cant remember where it was but i ve seen cranks bended with heat to a greater offset, dont know whats the influence on integrity with that. i wont try it under heavy...

in the video he mentioned the max rated power is about 3.somewhat kW. i think the 1.2 kW is for travelling speed (30-50 kph according to their website) edit: thanks for the link http://www.clean-mobile.com/drivetrain/ thats an explanation for the 6.3 kg. edit2: thats not the drivetrain they...

i agree its way overprized but the intention for building this bike was "whats possible?" not "how much?" thats typical for F1 related companys, they dont have to think about budget. this way many innovations found their way to market during the years, like ABS, traction control and so on. from...
