Not long ago one of our members reported exactly this kind of accident, although in his case it was a moment's inattention that led to him and his e-bike going into the canal. The bike didn't work after drying out and we never heard what happened to it. .

They have a few fans now, but are far from popularity yet being only a tiny minority of bike sales. I don't know what your idea is, but do some extensive checking first. There have been a very large number of solutions for belt drive ratio changing, and many of them patented. I'd be surprised...

That 's correct in UK law now, since April 6th 2015 in fact. .

Yes, the downhill can be far worse. And not just bikes, climbing a snow covered or icy hill with a good 4 x 4 can be childs play, but coming back down even very cautiously can be scary since there's nothing like the same control. .

That's one of the worst aspects, the terrible effect on family and friends. Some of the young women killed this year and last were EU working immigrants, their families living elsewhere in Europe and needing to come over here after the tragic death of their daughters. .

The best bit of commonsense on this issue came from the EU parliament early last year. Having considered the issue, they proposed a removal of all power limits, leaving legal control as being just the maximum assist speed while leaving the power required to designers. Sadly the EU Commission...

Buses and coaches have also figured among the HGV deaths over the years, so they don't protect as one might expect. That's why I disregard suggestions for side fences on trucks, since any long wheelbase vehicle needs a few inches of central clearance to cope with traffic calming humps and...

I've found it difficult to enough information on this, all too often there's partial and somtimes misleading information. I wish I'd kept the collection of scattered details I'd managed to assemble previously so that I could have repeated them. However, the reduction in male deaths is very...

I've looked previously with no success Mike, but there is the odd comment that suggests there is a small degree of national element in this problem. But it is mainly a London problem for two reasons. First the huge growth in London cycling commuting following the introduction of the congestion...

I agree, I dislike any rear sprocket under about 13 teeth, preferring to have a larger chainring. My currrent bike has a 60 tooth chainring so no need for tiny rear sprockets, 14 tooth my smallest. .

That's one of the suggestions that I've had to reply to previously on the basis of impracticality. The involved HGVs are the construction site trucks, usually 3 or 4 axle 20 or 30 tonners. When entering sites they often have to cover very uneven ground and this rules out both low forward cabs...

Pointless. .

Which is why the EN15194 specified power tests are only for complete pedelecs, not just motors. .

I didn't take notice of her name Mike and didn't recognise her, I was just a bit annoyed at her comment. So I just looked up the Liberal MPs now and found she isn't one! perhaps I misheard, or possibly she was an ex MP. I'll see what I can find out, if anything. .

In a sense the law is possibly being met, since there's a choice of how to test. One method inherently has room to get higher powers to pass, which is what I meant by "making due allowance". I think we are adopting EN15194 which includes that testing method. The national element comes into...

The law says it's the maximum. I don't agree with the conjectures that the higher figure is a short term rating, the issue is not that simple. Many of these "legal" hub motors are capable of running continuously without harm at well over the 250 watts rating. And I'm sure they can do that for...

Stop press. At last tonight's BBC TV London News has highlighted this issue of female cyclist vulnerability. Sadly it took six female deaths this year to make them wake up Not all good news though. They quoted some irrelevant figures. They had on a female Liberal MP from an outer...

If that was the case Michael, oriteroom has answered it. The number of men getting killed this way has been reducing over the years, at a time when all London cycle commuting has been continuously increasing. Here's my own observations from living, cycling and driving in London. Several years...

BMZ use 18650s in these Kalkhoff batteries, I posted a photo of their internal construction above. Here's what they say about their 11 and 15Ah batteries for example, copied and pasted: 50 Cells | Type 18650: 10 Cells serial à 3,6V x 10 = 36 V 5 Cells parallel à 2,25 Ah x 5 = 11,25 Ah 5...

This check is the battery capacity (Ah), as opposed to the charge content that's indicated by the short press. Your five LEDs lit indicates it has the full capacity a new battery should have. .
