A few more brushed controller links. Fortunatly they can be pretty cheap as they're commonly available for scooters. - providing you can live with throttle only that is. Electric Scooter Speed Controllers from ElectricScooterParts.com Electric Scooter Parts Page #1

YouTube - Making Custom battery Packs Battery Pack Building: end-to-end soldering Easy once you get the hang of it. Use lots of old nonrecharable batteries to practice on first :D I've just discvoered the illegal lead ebay stuff too:) , much easier to use. though i've used the...

Its a very pretty bike, no doubt about it.

You sounded quite succinct to me, the wonders of a good editing team;) . Thankfully they edited down my 10 minute of gibberish into something reasonably sensible. I'm particularly glad they didn't include my ramblings on the middle east which in retrospect made no sense at all:eek:

I got there a bit late, I was with Steve (the guy with KMX trike). Was a bit dissapointed the rally was cancelled as it would have been fun, would have also liked to meet more people and thier bikes (not sure who I met and who I didn't as our internet ID were not so easily visable :D) but...

my nimh chargers flash very fast when the chargers doesn't get a thermistor reading. Might be worth checking all connections to see if anything's loose/dirty.

Hi and welcome. Sounds like an interesting project. I have a 30mph 1500 watt peak ebike/electric moped but I just modified the a standard electric bike kit to get the extra power. I imagine the drive train will be the trickiest part. You get fit dual freewheel sprockets for bikes but...

I'd agree with that generally but for the purposes of pure pedanticism I should point out the 24 volt brushless currie has pretty much identical peak and continous power as the 36 volt powabyke ;)

I've heard that if your order under £18 you don't get charged postage or VAT, not 100% sure how true that is but its held for me so far.

Hi there Tintaglia, Your pack might still have some life in it yet. My experience of nicad is that they can last a very long time but are sometimes prone to failure. Such as cell reversal or sudden increased self discharge. It could be you have 1 or 2 bad cellls in a good pack. If your...

I'd be happy to respect a 20 mph general speed limit even if it doesn't apply to my bike. I'd much rather have specific speed limits regulating ebikes in specific areas (such as bike lanes in city centres/ and mixed use pedestrian areas) than a general speed limit for ebikes such as the 15...

Hi Dirk A couple of you might want to think about are. The ezee has a 22 mph boost button. nominally for off road purposes, as far as i can tell the whispter does not. Whatthe battery warranty is on either bike. Both claim various cycle lifes. The cycle life claim is pretty...

Wow, nice find. On their site they have a category called 'kit'. but how could you fit it to a normal bike? The other things thats puzzeling is would a normal derailer take 750 watts let alone 2 KW :confused:

That explains it. You can't get more speed without more volts. The exception is where the speed is limited by the controller such as on bikes like the torq.

Thanks Flecc, I'll check that out.

Interesting Stuff Flecc, Would I be correct to Sum up as: comfortable, well designed base bike + correctly optimised motor + good range of gears = Very efficient long range electric bike? You put my 'more amps plus more volts' philosophy to shame :D

Interestingly, I've heard it was for this reason that Toyota specifically limited the state of charge on the their nimh battery pack to between 30-70%. I think they had good data showing that the pack doesn't age in these conditions. As far as I know they been proved right, at least compared...

500 cycles at 80% (dod) is a normal rating for lithium batteries. 33% capacity loss in the first year definatley isn't. I've not seen any data on this kind of lithium chemistry(maganese). The only information is the reports from you and Flecc on this forum and also a brief mention on the...

Hi Peter, No techical barriers, only legal ones! My bike will do 23 miles in an hour ;) (http://www.pedelecs.co.uk/forum/electric-bicycles/53-show-us-your-bike.html#post311) Sorry to hear about your battery experience sounds really unfair. I don't see why ezee don't offer at least a 1...

Hi Steven, To sustain 20 mph over 23 miles your going to need a big battery. Ian suggestion to drop your speed will make things less expensive. You might want to look at the crystalyte and Puma kits and lithium batteries from Team hybrid (teamhybrid.co.uk hand cycles | Home page [tel: 00...
