Should have pointed out that the current battery will be up for sale shortly and the hub will be run on LiPo,lots of LiPo...This hub motor isnt going to be used up big hills but mainly for trips to various pubs around the dale where a BBS is not suitable as I may be too drunk to change gear efficiently.You need to bear in mind how much current your battery can give. I think it's already pressed to its limit, so soldering the shunt in your Dillenger controller might not be a good idea.
Torque also increases when you over-volt, but this pushes the efficiency curve up to higher speeds too, i.e. not so efficient when going slowly up hills, so you can get over-heating.
Overall, it would be much better to change to a geared motor.
If the first thing I read upon finding this site was the replies to your posting(obviously not connected to your excellent first post) then I would never of returned.Further to KudosDave's post, there's an extract of the main state differences in American e-bike law in this post of mine

Kinninvie....please do try a BPM motored hub drive bike,you may be pleasantly surprised as to the low speed torque that these motors offer,I am trying to use this motor on every Kudos bike,whether it is a commuter bike or mountain climber. It is the most cost effective legal means of providing the right amount of hill climbing power at the speed most of us require it.They should copy the Yanks and set the limit at 750 Watts.
My 250 Watt Cyclamatic Power Plus (I think the plus means plus we just lied about the power) wont pull me up any of the hills around here even with me pedalling as hard as I can!
Mind you my Kilowatt Dillenger wont pull me up the steepest ones here either.
As for the 250 Watt scoooter,it wont even pull me on the level iof the winds blowing the wrong way.
It's fudge wording. In practice it means a manufacture has put a 250w lable on the motor.The Ebike regs upped to 250w in UK, 15.5mph, to harmonise with EU, the law comes into force on 6 April 2015, here it is: http://www.legislation.gov.uk/uksi/2015/24/regulation/2/made
Interesting definition of “maximum continuous rated power” at note 3 at the bottom. Can't quite get my head around what it means.
Unlikely, that regulation incorporates the 2002/24/EC Type Approval Regulation as part of keeping things current*. In that document section 1, subsection 1.h. exempts pedelecs meeting the EU pedelec law from being motor vehicles and all the rest is about two and three wheel motor vehicles.triumph of common sense. Will we have to comply with all of EU reg 168/2013? it's a 77 page PDF.
Actually it's been pointed out by some here including me I must confess, that with clarity the law might start to be enforced. As it is it's a minefield that the police would rather not get into. Particularly since a police force which was keen to prosecute under the current law was stopped and effectively told that it wasn't in the public interest. But now if Dibble sees someone moving right along with little apparent effort on something that looks like it was a prop from Star Wars he might just do something about it.Fortunately, all the tests for assessing the maximum continuous rated power are to stop people from overrating their motors, which can result in a fire. There doesn't seem to be anything to stop them underrating them.
We can all ride our bikes now (in a few months) without worrying about insurance claims and private prosecutions. The only problem is that all those holier than thous that have been riding illegal 250w bikes will now get back on their high horses and lambast those that choose to push the limits further.
So all those posters who were bleating about my dongle in a recent thread are breaking the same rules themselves.Y I'. thinking more about those with 250w bikes who release the speed limit. We've had a lot of hypocritical preachers on here that tell them that they're a blight on society for doing such illegal acts, while they themselves were riding illegal bikes. Since I pointed that out to them, they seem to have shut up, but I guess now they'll all be at it again.
My guess is that the old 200 watt law was not enforced because anybody convicted under it would appeal to Europe claiming that their bike met European Law and it was all the fault of HMG dragging their feet.
AND
Just why did they?
