Yes it does

Thanks very much. Exactly what I was looking for. With just that little bit of soldering how many more amps did this give you? Also was it very noticeable on the bike and in what situations?

Also how will I know how far I can go without killing anything? If I solder 20% and it feels good can I solder the whole thing? Bigger and bigger. Can of worms me thinks.

Sorry, what do you mean by 20% of its length? Total noob here. If I find the shunt do you mean put globs of solder 20% across its length making it much fatter on that bit? If so how big a glob should it be. Sorry for being thick.

[quote="danielrlee, post: 233090, member: 8220" Modifying the shunt will alter the power of the motor (acceleration) at the expense of range. I like this idea :-)

I will test and find out the voltage, I'll have to try and find a volt meter somewhere Yes, sorry, it is a lipo pack.

Brill, I think I understand now. I'm starting to think now that rather than spending loads of money to get higher topend the best thing to do would be to do a free mode and do something to the shunt (what ever that is lol). Is there a limit to how far I can go or is it a fixed amount or.. I dunno lol. Any guides on what to do to this shunt thingy :-)

OK cool. So if I bought a different controller and decided to stay at 36v but more amps, would this keep the topend the same but more torque? Also with a new controller would I still be able to use my display? Is it all plug and play to a new controller?

Thanks very much for your detailed reply. I'm still unsure what is actually limiting the top speed. I think I have exhausted the display controller by playing with all of the settings which didn't seem to affect the speed. I'm a total noob when it comes to these bikes lol. I do have lots of 3s lipos (2200 to 5000) laying around and a couple of 2s (1000mah). Anything I can do with these to test anything? What would I be looking for in the controller? I have heard of soldering the shunt... Or something like that, what is this and what will it do for me? Many thanks again for your help.

I've got a bafang rear hub motors rated at 36v 250w. I'm interested in this add on http://www.bmsbattery.com/111-12v Adding this to my 36v battery I will get 48v. Is this all I need to do or will I also have to change the controller which is rated to 36v. If so can you recommend one please. Also what will he the result of this mod? More power? More speed? Thanks very much.

Perfect garyten, thanks very much. From reading those instructions I got in to the speed settings of the controller but it's already set to Max 40kph but tops out at 25-27kph with no assistance after that speed. . Strange. I have adjusted the wheel size but although the speedo reads faster and slower depending on size the wheel seems to spin at the same speed, haven't confirmed this with a separate speedometer but just by eye. The speed sensor seems to be built into the hub as I cannot see anything else on the bike. Any ideas?

Just come back from a 10 mile round trip as there was a break in the weather and I got to say I love this bike lol. Awesome. Would be that little bit more awesome if I could remove the speed limit lol.

It has speed in kmh on the display. It's a geared bafang 250w rear hub motor.

How do you disconnect that? Can't see anything on the wheels

OK thanks for your reply. Pics attached. Pressing m and + together gives me the first picture, selecting y then holding m give me an option to enter a code. I have tried a couple that I have found online but none work.. Any ideas? I have tried 2007 2008 2009 Thanks very much for your help.
