Re: Charging AAA batteries on housephone handset

Update. Sorry doomsters ( :D ), but after nearly another 3 years I'm still using this charging regime, the old Kaifeng 550 mAh batteries still holding charge well and now at least 10 years old. Ref the cost of mains recharging. I've always fancied buying a plug-in mains ammeter, especially one which...

Re: Continuing cycling in older age - what is the secret if any?

As stated above, cycling is excellent exercise but other activities are important, eg for bone density issues. My general rule is: never drive if I can reasonably cycle, and never cycle if I can reasonably walk. Most of my local trips up to two miles are on foot (minor shopping, appointments etc). L...

Some manufacturers seem to be abandoning this feature. Not many of us bottle-users left, I suppose.

Re: 2 chainring versus 3 chainring crank

+1 for triple. I've spoken to so many newbies who get persuaded to buy high-geared doubles ("...nobody uses triples any more, sir"), then get thoroughly demoralised when they do the walk of shame up a not-very-steep hill. And the simple answer to the difficulty in fine-tuning a triple to a...

Alpine lake tour suggestions

Planning a trip for next year taking 4 not-so-fit middle aged cyclists. Some are nervous in traffic. We've previously done a Danube bike cruise which was perfect (no real hills, mostly traffic-free) and are contemplating a similarly unchallenging tour. A moving-on circular tour around a large pictur...

Re: Tent run over at campsite

https://www.bbc.co.uk/news/uk-wales-49411705 Driver charged. Some injuries, one serious. I have a "thing" about camping with motor vehicles in the same area, and try to use sites where they are segregated from lightweight campers. Years ago I spent a very uneasy night at a poorly-regulated...

Naive battery question

Recently had to buy a replacement battery for wife's ebike (£400 :shock: ). I calculate that when fully charged it contains around 400 watts, and weighs around 5kg. I just weighed an old car lead-acid battery at 13kg. When fully charged it holds around 480 watts. The battery costs around £40 new. Th...

Re: Canti straddle wire - is it special?

Many thanks for the advice. The original cantis are obviously cheap (maker's name has long ago rubbed off) but work well. A standard MTB brake nipple sits nicely in the yoke, I'll go ahead using standard brake wire and keep a cautious eye on potential fraying points.

Canti straddle wire - is it special?

Is there any reason why I can't use ordinary brake cable to replace a frayed straddle wire in an old MTB? The wires look and feel like the same gauge, but presumably the straddle wire suffers more powerful forces?

Re: A red rag to the motoring lobby

The "indicating only when necessary" thing seems to be from police driver training techniques which were continued in the Institute of Advanced Motorists (whose examiners were all police driving trainers.) It's one of the things that's easy to test so it became accepted as good driving. I...

Re: E-bikes and 737 Max

Good point, these things can happen.
However I reckon that if my wife's street-legal 250 watt e-bike suddenly went berserk the rider's natural reaction to slam on both brakes would soon overcome the unruly motor!

Re: Risks of buying old alloy-framed road bikes ( 15 years+ )

You could find a bargain, but there are risks. At worst a catastrophic fork failure.
Have you considered an entry-level new bike? https://www.decathlon.co.uk/rc100-road- ... 77732.html ...this at £250 should at least give the assurance that it's not going to collapse!

Must I buy from Halfords?

Looking to buy a spare battery (36v, 11.6ah) for my wife's Carrera Crossfire in order to do an extended tour. The only supplier appears to be Halfords, £400 (although I assume my CUK discount will get that down to £360). Does anyone know of a cheaper source? Maybe an alternative make of battery whic...
