The motor is 8-Fun BPM

I think you have a good idea but the program logic is not very logical.
You can't build a virtual bike from components that people input to the screen alone, the result won't match reality unless you have intime knowledge of what each component is caapable of and how it influences other components. For example, you calculated power = battery voltage * controller Amps. Power varies greatly with speed, wind direction and speed, local gradient etc. A mid position crank drive gives different torque and power values depending on the front/rear transmission ratio and bike speed, much more complicated calculation than a hub motor.
You should start by building a database by asking people to input their trip data, which bike, from, to, speed, wind direction, wind speed, biker's fitness, weight etc and their time. From that, you can work out the + and - points and how efficient each system is. You can look up the manufacturers' website for its component list.
Then when somebody asks for advice, you pull out of the database the nearest matches.
Thanx for interesting idea, but you are wrong, power formula you have mentioned is only maximum output power, but program calculates load and output powers of motor by using much advanced formulas, while wind direction,gradiend etc. Is taken into account.. results of ebikeselector are similar to other simulator like ebike.ca simulator or epacsim,i do comparsions regulary.. Differences in results are mostly very small..

anyone can tell you that maximum output power is not battery voltage * controller Amps and the BPM is capable of a lot more than 8km/h.

Yes, They may be bugs because its beta version.. I have already mentioned bug with middle drive motors in previous post, anyway thank you for feedback..

I clicked on the link given in the first post and immediately got a response saying

App Not Set Up: The developers of this app have not set it up properly for Facebook Login.

I am using Firefox on a MAC.

I can however close this box and continue!
This is because app is connected with facebook plugin because of "sharing results" feature, so facebook opens popup login window in some browsers which don`t block popup windows. I will try to fix this, thanks for info.

Hi Trex,
Last time i couldn`t post adequate reply because i was in time pressure because of my studies, also my computer was broken.. So i`am sorry if my reply seemed strict (or rude), it wasn`t ment this way.. Plese can you post some sources related to your explanation of max. output power? Because on most of sources i have found, Peak Power (ok,i use term max.power) of ebike is described as volts*amps.. For example here: http://www.atob.org.uk/electric-bikes/electric-bike-technical-guide/ , but i can post many other sources . About bug with BPM, i couldn`t check it last time (because of broken computer). There is a bug which resets gearing to 1/5 on middle-drive motors , so gearing needs to be refreshed to 1/1 by hand. Speed 8 is a adequate speed for 1/5 gearing (checked on Epacsim simulator), with 1/1 gearing ebike will be much faster.. I have mostly tested App on DD and geared Hubs, so Middle drive needs to be polished , but bug with gearing is a typical "betaversion" bug, so it doesn`t mean all program and it`s calculations is wrong.. So just be fair, please..

Hi,
New update of app is online. Mostly bug fixes like adding compatibility with IE (ie9 and newer) but also some improvements like Adding simple middle drive simulation (yes middle sim didn`t work as middle sim in previous beta, thanks for feedback).. you can se full list of changes here:http://www.ebikeselector.com/blog.html
Thanks for your visit or possible new feedback!

Hi,
i have posted a new version of app - http://www.ebikeselector.com/. This time i was more focused on bug fixing, but there are some improvements too
I would really appreciate your feedback or comments!.


Improvements:
  • Added 2 wheel drive (also called 2WD ) motor simulation - 2WD can be selected in "Motor position" component in Advanced Selector. Currently two identical motors are supported, but this may be improved in future versions.
  • New conflict type "tool". This conflict type ( marked with "tool" icon) appears if some components is not possible to put together because of some technical aspect (size, compatibility). For example some wheelsize does`t fit into some frame types, or if user pick rear battery but doesn`t have any rack selected..
  • Center of gravity conflicts - In the previous version this conflicts type appeared when some combination components was detected, for example Lead Acid Battery and rear hub. Now it works with results of CG calculations, so it really takes into account weight and position of components.
  • New Physics status icon. This Small icon with "bulb" informs if ebike physic is ready or not. list of components needed for activating ebike physics appears after "onmouse" action on icon. Icon will change color to green, when physics is ready.
  • Country restriction improvements - Speed Restrictions - if country restriction include speed limit, speed is restricted directly into physic calculations (in previous versions there was only information provided by ,conflicts, window). This restriction is marked with "shield icon" placed on speedometer.
  • Country restriction - added new countries - Australia, China, Canada.
  • Component selection- After selecting component in Interactive Image, equivalent component is selected in component list.

Bug fixes:
  • Lot of bugs fixed, so many that i`ll not list them all. This time i have put more attention into testing the app, so i hope that you shouldn`t expect some fatal bugs.. Of course it`s still beta, so some minor bugs present (i have about 60 bugs in my buglist).

Went all the way through this thing and all it did was tell me to take a test ride, wow, would never have thought of that myself, shame there was no mention of WHAT BIKE TO TEST RIDE. Complete waste of time.

Eddie, you haven`t specify too much details about results that program gave you. So just short notice.. You will find advice to make a test ride in any good detailed ebike guide, also every expert will give you similar advice at the end of his recommendation.. Thats because there are many ebike variants, so first you have to know WHAT you want and then you should make test ride. (because it would be little bit complicated to test all ebike types without reading any information before)

Program didn't give me any results, just told me to take a test ride.

Is there any point in carrying on with this?
New bikes are coming to the market on a regular basis.
New batteries and motors are being developed.
To me, it all seems pointless to have a program to find the best bike.
Most people either read the available literature and make their own minds up, or buy what ever the local bike shop has to offer, reasoning that repairs will be simple and local.

Mike, i understand what you mean. On other hand, many people want to be informed before they will buy their ebike, and this program is one way they can choose.. Of course there are many guides, forums and other sources and it`s up anyone which way they choose. personally I have spend weeks of reading various sources before i have bought my ebike.. Some sources are great and comprehensive ,but sometimes there is only partial info, so i had to write notices with summary from various pages a forums.. At the end i had more than 20 pages of various notices and comments i had to organize, then i made decision.. Reason of making this app was to give you quick idea about ebike, maybe not comprehensive, but with all basic options and possibilities, then you can find more detailed info in other sources.. Only short comment, Ebikeselector is not only program for finding the best ebike. This is only part of program functionality. Program is also ebike guide, ebike configurator and ebike physics simulator.

Hi,
New update is online, you can check it out at http://www.ebikeselector.com
Feedback would be appreciated!
Milan, Ebikeselector admin


Improvements:
  • More ebike setups as result can be displayed - This is important improvement. Ebikeseletor now displays ebike setups not only made from "best rated" components, but it will also display lower rated (but still good or usable) components.

    Currently three setups are available, first setup is usually most relevant. Setups can be changed by clicking on "rotate" button. After onmouse action on this button you can see graph that shows ratio of best/good/usable/blocked components.
  • Detailed information about component rating - onmouse action on rating icons (
    ) reveals tooltip with detailed information about component rating in Question selection. This info is different in Final/preview mode. In Preview mode you can see basic component rating chart (how components are rated in relation to selected question). In Final mode you can see a list of winner rating components from all selected questions. This information should give you detailed information how components are rated and allows you to understand how Ebikeselector rating system works.
  • Conflicts in easy selector improved - conflicts now appears in small popup boxes. This will make conflict solving easier, no need to skip to "conflict page" and then back to the question.
  • change way how to work with PHYSICS SETTINGS in easy selector - Physic setting can be now accessible from any page in Easy Selector so it allows you to quick access to physic settings.
  • Easy selector - add presets and LOAD function - In previous version this function was available in Advanced selector only.
  • Rename and adjusting of Preview / complete switch button - In advanced selector, button was moved to the right menu. This was more logical, because switch is not connected to "questions", but it can be also used generally for switch on ebike physics. Preview / complete was changed to Preview / Final - shorter name was needed to better fit redesigned button.
  • Easy selector GUI redesigned and improved Improved intro help popups, this steps should let users to better orient in easy selector. Added "bulb " icon that informs about physics state. (in previous version this icon was only in Advanced selector)
  • Advanced Selector - Question Selection hidden by default Some users was confused from dual functionality of Advanced Selector, where is possible to use Question selection and component configurator together. I hope that without question selection it should be little bit easier to orient at start of using program. Question selection can still be used, after unfolding menu.
  • Amazon product link removed - i had to focus on bug fixes and polishing of important features, so i have to temporary removed this feature. Maybe it will be added back in future updates..
Main bug fixes:
  • Fixed throttle middle drive - decreasing Throttle didn`t work properly when middle drive motor was selected. fixed now.
  • Share results fixed - Sharing ebikeselector results by using of generated link should be fully functional now. Use Share result function (Advanced selector main GUI or at bottom of summarize page)
