The media love to exaggerate. The commentator of a recent Channel 5 program about a UK police force stated that some 5000 UK motorcylists are killed every year. In fact that is the number of injured recorded, those killed in the last year figure I saw recorded was 328, somewhat less than 5000. .

That will probably be due to the absorbtion of applied torque. Given that the force applied by the operative will be the same both sides, that on the right will all be tightening. That on the left will have some of the force soaked up by the twist in the BB spindle and lost as heat. To...

You might need to learn Japanese though! ;) .

I think this is rather theoretical. Because the left pedal force is transmitted through the length of the BB spindle, that spindle will twist very minutely*. Therefore the crank arm will travel further in distance and time to accumulate the additional torque. And it's that extra torque that...

I'd say less force at any given moment, but for a fractionally longer distance/period. See my simultaneous reply above your last post for the longer screwdriver principle. The length of the BB spindle adds torque in the same way that a longer screwdriver does. .

As Mike says, the principle is the same as that when using a longer screwdriver to apply more torque than a shorter one. This twisting force within the BB spindle is employed in the Panasonic crank units as the the torque sensing of pedal effort to control the motor power added. .

The first ever tyre specifically for electric bikes was made by Maxxis in China and fitted on many Giant Lafree e-bike models from 2001 onwards. They still make a variety of e-bike tyres but no-one in the UK seems to stock them. They are available from some suppliers through ebay though, here's...

All the best for the new location Tim. Being opposite Pearson's with their lycra clad roadies enjoying their coffees should be interesting! .

A more sensible radio program this time, on BBC Radio 4 at 8pm tonight or can be listened to later on the link below. Clive Anderson and a panel of legal experts discuss how changes to our traffic laws could reduce the numbers of motorists, cyclists and pedestrians killed or injured on the...

Yes easily, considering how many years and miles he's ridden his powerful eZee motored models. As John says, Wai Won doesn't like crank drives and he made that clear to me years ago. .

Not powerful enough for him possibly, Shimano's e-systems to date have reputedly been moderate in approach. However, it could just be his preference for hub motors, those long used to hub motors like him often find difficulty in acclimatising to torque controlled crank drive. .

Yes, it certainly could have been worse. I think the program's producers belatedly woke up to how bad it could have been and ensured the direction and contributions kept it under control. .

Agreed. In fact it's now narrowing down to even fewer guilty people acting without the banks authority to make their job of money making easier. One individual named in today's news is now being prosecuted having previously admitted being instrumental in manipulating the LIBOR rate, also...

The program is on at the moment. You'll be able to listen to it a few hours after transmission on the BBC i-player on this link .

As Kudos Dave says, your only worry with an overspeed e-bike is if you have an accident. Then if a police check shows it is illegal, you will have been riding a motor vehicle, not type approved, not registered or number plated and uninsured. If you don't have or are not qualified for a moped...

You're in Peter, riding on King Street by the Virgin Money Lounge: Map Link .

The Q licence or an equivalent may be EU wide since it relates to the Low Powered Moped class in it's latest EU guise, L1e-A. The existing moped P licence covers class L1e-B, which are the 30 mph mopeds. Both L1e-A and B are subject to new type approval legislation, it's measures being phased...

Seems most likely to be the controller, especially since you had a clicking noise from it after the fault occurred, definitely not normal on these. The eZee controller is generally one of the most reliable, but they do fail on rare occasions. I've never known or heard of the battery meter...

St Johns Cycles have two extended ranges of 14 gauge spokes. This first range in 2mm steps I've successfully used with hub motors, but unfortunately currently out of stock until October: 120 to 194 mm 180 to 314 mm .

Yes, they are compatible. Indeed the Acera rear mechanism works well even on six sprocket cassettes and Megarange rear sprockets. In general anything from 5 to 8 sprocket cassettes are compatible, it's the 9, 10, and 11 sprocket rear clusters that need different accompanying components. .
