Thanks, I'll check my connections for shorts and report back!

I've read the reports of battery problems which several Kalkhoff owners have reported recently with some concern. This morning it was my turn. My Ping LiFePO4 battery has been in the garage, but unused over the recent cold spell. The sun was shining this morning, so I gave it a top up and...

This is what I said last time it came up

In which case you've probably got your filters set already, John!

Bigger than a Powacycle! I think that had an 8Ah NiMH, and gave good range. If the system is matched to the battery it can still give good results.

Looks good! One question - where is your controller? I couldn't see it. I hope it's not in the black bag on your crossbar, as they need to be in the open air to stay cool, as they have been known to burn out! Also, what motor speed are you using and how does that translate to hill climbing...

Interesting report, but all I get on the photo site is a big red no-entry sign with lots of Russian writing! Would be interested in seeing the pictures. I too laced a Tongxin into a wheel the other week as my first wheelbuild; not as hard as I'd feared!

I'm not sure I agree with that! Just because someone once misused statistics with tragic results does not give you grounds to declare the whole science to be in default. There lies the road to dumbing down. Remember many statistical techniques were developed specifically to predict...

Just playing around with statistics a bit more (and assuming of course that the seller was not the sort of company which would return the duds to stock!) if a company sold 1500 batteries in a year, I make it that you would expect to see one customer getting a dud first time followed by a dud...

Definately buy that lottery ticket! I don't think your maths is that far our, BM. I heard that 1500 Kalkhoffs had been sold, and if there are only 6 defective batteries out of that lot, there could only be 5 chances in 15,000 of Tillson getting a failure the second time round (as he'd...

I'm afraid it's the analogy that is betamax! You could say that Wisper and Ezee use the same format (hub motor) and Panasonic bikes like Kalkhoff use the other format (crank motor) but as the electricity they need comes in a form that is compatible with either format, they can all happily...

That's an interesting idea. If you did it I think it could work and you might have invented the electric rowing bike! But you would need high gears and much lower cadence - perhaps 30-40 would be achievable - and it would be harder on the knees than cycling! The tandem would certainly be...

I'm not the expert on those folders, but given your relatively short journey in a flat area, I would have thought most bikes would do the job. Critical issue with folders is to make sure they have high enough gears to enable you to do whatever pedalling you might want to do. Urbanmover has...

Sorry to hear of others falls. I've left my bike in the garage all week and was rather missing my ride in to work, but, reading this, I think I shall wait until the frosts have gone before getting it out!

What eBay now seems to be doing is not allowing the loser to take the money out of his / her paypal account for xx days after the transaction, in case the winner turns out not to have been so lucky after all!

Keith, you know how when you buy something, eBay likes to say you have 'won' it, to make you feel good / lucky? Maybe they're applying the same logic to sellers now, calling them 'losers'? So for every bargain that someone 'wins' or as we used to call it, buys, there would then be a loser who...

Not really! He was a guy who used to work at 50 Cycles and who doubled up as a forum troll

Keith, be careful - there's a 20kg limit!

Well done, Bob, for getting to the bottom of it. I think I remember reading a post by David a while back saying that they had changed the levers to improve the brakes, so I believe you are right.

I use one of these as an improvised workstand. It's rated at 20kg weight, is fully adjustable, costs next to nothing, and takes up no floor-space! It's priceless for adjusting gears, which is what I am going to do right now...! Frank
