The power requirement to propel an average cycle with a rider weight of 70kg and an average drag coeficient @ 9mph is approx 30watts. Each pedal down stroke would thus be 30 watts as well - but technically you're measuring a turning force there so you'd be looking to measure torque, not watts...

Meh, real mean use proper measurements. One white knuckle Two white knuckle. ........ Nnnngh that's bloody tight And finally 4 bloody knuckles, someone pass me the lump hammer.

I think alot of people are missing that the op uses spectacles, so a lot of the recommended options above just aren't available to someone who needs spectacles. I use ESS ADVANCER V12 GOGGLES with the RX inserts. Specsavers glazed the inserts for me for £30. I really like them and my eyes...

Sorry - I meant the motor on the Machina is a geared motor which includes a free wheel. It's been a long day!

The hub on the Trek is direct drive, which is why it was quieter but why you also noticed some drag stopping you getting above 30mph. The hub on the KTM is geared, so a bit noisier as the motor runs at a higher rpm and you can hear the gears. It also incorporates a freewheel which makes it...

It's just a PWM restriction in the controller, like how setting my speed switch to position 1 limits my speed to 16mph.

I haven't balance charged my pack since October - that's around 100 cycles. I use a Meanwell power supply to bulk charge. http://www.pedelecs.co.uk/forum/electric-bicycles/9442-new-build-5.html#post125688

Right, so what is your chain wear tool showing then? For wear on the rings - it's hard to tell from that angle of photo but check this pic:- Big ring - worn a bit but ok for a while yet. Middle ring - very worn, needs replacing. Small ring - no wear at all.

Chainwheel teeth aren't symetrical - there should be a shallow "hook" on most of them. Any pics? What did the chain measure at when you replaced it?

Yeah - sounds like you have non ebrake levers. Put your old levers up and rig up a switch on the original rear brake (you only really need it on the rear brake - well at least if you're braking properly!). http://www.pedelecs.co.uk/forum/electric-bicycles/9442-new-build-11.html#post163831...

It doesn't matter. EU rules dictate that poducts should last a reasonable length of time when subjected to normal use. For example, my washing machine only had a years warranty but I got mine replaced after 4 years as I could demonstrate it was a reasonable expectation for it to last longer...

Have you spoken to Kudos?

It's either stolen or knackered. People don't usually sell perfectly usable batteries. The old adage applies here - if it seems too good to be true..............................................

Ouch. Then again, if you're not crashing then you aren't trying hard enough!

Bristol car-free Sunday closes roads

Well, it's not criminal - there's no debate about that. I thought we all rode ebikes here, not high horses!

Photos of the bike please. It might be a candidate for a crank drive conversion and battery in a back pack. Big hit looks like it uses through axles so hub drives wouldn't be an option.

Or the fact that when you turn left or right the basket will tip on it's side and empty all the contents over the floor.

It's only an offence not to report if there's been an injury, otherwise swapping details is enough. EDIT: Doh, beaten by d8veh! There's a good post on Bike Radar on what to do in the case of an accident:- http://www.bikeradar.com/forums/viewtopic.php?f=40052&t=12722930 Do you have any...

acf50. Don't get it on the braking surfaces though.
