In fairness most of the £1000+ bikes do have good quality cycle parts and compare in quality terms to mid range conventional cycles, and some of the excess cost is used to provide back up and spare parts availability, something that is usually non existent at the lower end of the market. My own...

As with any product the cost has little to do with the true value and everything to do with what people will pay. Until there is more serious competition at the higher end prices will remain high. As Maggie used to say "The market will decide".

Apart from any concerns about linearity I wouldn't fancy using a pot because of concerns about reliability. Only the highest quality industrial spec. rotary pots would be suitable in a wet dusty environment, and such pots usually require a high operating force. A slide potentiometer would be...

I wouldn't worry Paul, Sustrans has an enviable reputation for doing what it says it will, one only needs to look at how quickly the National Cycle Network has grown to see that. The lottery money will be released over a 5 year period though, and while work will start next month many will have...

Very unlikely as the the manufacturers will almost certainly have changed the gearing to compensate for the smaller wheel size.

I love the third picture, with the soldier (or should it be model) sheltering behind the bike, presumably from a hail of AK47 fire.:rolleyes: :D

Different bikes, or more specifically different batteries do require different chargers. I'm not familiar with that particular bike but the size of the battery does suggest it's a lead-acid (SLA) type, this type being the least fussy and therefore the most suitable for use with a generic SLA...

All seat posts on all bikes have a minimum insertion distance into the seat tube, if this is not adhered to then there is a risk of frame failure. The problem can also occur where the user has fitted a longer seat post to maintain the minimum insertion distance or the seat post diameter is...

I can't think why it's got brake lights and indicators as it is clearly can't be used on the road as a legal pedelec.

Me too Steven, living at the other side of the park. Although it has to be said that it's not at all bad at present, at least for the able bodied. Some of the brdges earmarked for improvement are a pain, especially for the disabled, hopefully the muddy bit at your end will finaly get a proper...

Great news. Well done Frank for spotting it.

Why not use the seat post to conceal the rocket and build a delay into the firing circuit.... to give the thief time to mount :D

I do a similar thing Stuart, I try to lock the bike in such a way that a thief needs to move the bike to gain access to the lock, hopefully triggering the movement alarm in the process. I don't think any number of locks and alarms are OTT, almost every day I hear first hand accounts of...

Good idea John, the tape could be electrified as well, but with a lower "warning" voltage:D

I thought of using the bike frame as the earth since an unsuspecting thief would be likely to touch the frame and lock together. Of course the the whole idea was only proposed in jest as in reality the bicycle owner would be prosecuted for hurting the poor little blighter who was only trying to...

Don't forget that on the continent they don't usually class bikes as being for use specifically by any one sex, the two frame types are simply different frame styles, each equally usable by either sex. The quoted frame sizes on all types are the measurement from the bottom bracket to the top of...

Try this. Its not an alarm as such but if wired directly to the lock it should prove an effective deterrent

It annoys me that suppliers continue to insist that only a small percentage of users have problems with lithium batteries when quite clearly almost everyone experiences a life that is a fraction of what is claimed (but not guaranteed:( ) Maybe only a small percentage complain, but if this forum...

I really meant every week :D

Some time ago I bought a fairly expensive Kryptonite D lock, with a sold secure rating, only to later discover it could be opened with a ballpoint pen. I think these stories illustrate that no single lock can be regarded as completely secure, the best approach being to use a selection of...
