Re: People shouting 'left' 'right' etc on a cylce path whilst approaching from behind

My view is you shouldn't be calling out at all, It's a misnomer to believe that calling out is merely to inform other cyclists on the road/trail that you are coming, it is in fact to tell the other cyclist to 'hold their line' so as not to veer into you. ...and what happens when the road conditions...

Re: A noob asks... what is the point of toe clips for a commute?

To all those claiming that no-one 'pulls up' I have pulled a number of cleats off the bottom of my shoes... Isn't that partly because hydraulic action from walking sucks in water that corrodes the bolts? ;) That's what happened to the ones holding my cleat blanking plates on when I stopped using th...

Re: Ever been stopped at security at the ferry port?

Stopped and searched at Portsmouth outbound. It was a 'Jobs Worth' who made us go through a scanner after making my wife and I take of our shoes. It was raining hard at the time and the floor was wet and filthy. My wife expressed her view to him and his response was.' We've stopped a lot of terrori...

Re: A noob asks... what is the point of toe clips for a commute?

The other minor benefit that I hadn’t seen mentioned after reading the first n posts... Even loose clips ensure that you keep the right bit of the foot over the pedal axle (assuming they are correctly adjusted). I use spd ‘clipless’ pedals because on a ‘bent trike I can’t fall off and really don’t w...

Re: Hand-bikes and suchlike

Yes, they do (I used to swim a lot) but in fly and breaststroke a lot of the power comes from the torso - one of the reasons fly is actually faster than crawl over short distances - massive muscle contribution. The offset when pedalling makes sense - you can’t generate all that much power with the c...

Re: Hand-bikes and suchlike

You don’t offset hand cranks - the strength comes as much from the core as the arms, no good trying to twist the torso.

I’m sure you could have a two wheeled one, but I think balance would be an issue overall- the amount of body movement needed is likely to be quite difficult to counter.

Re: E cars and the change to the urban landscape

Yes it will change the landscape - but such terraces will be the last places to change. You’ll have car parks for charging... You might even have a few electric points on the kerbside - with the car registering who it is when it plugs in to bill for the power (you don’t need a cable to your house, j...

Re: Utility Cycling

Ban the advertising of cars as thrusting weapons of power and aggression, driven very badly by svelte poseurs to impress others, especially others of the opposite gender. Can you suggest some wording for legislation to achieve this? See tobacco advertisements as an example. We don't see any any mor...

Re: I want one of these!!

I suppose we'll have to forgive you the clickbait... A few points: The invention, which is about the size of a skateboard, is powered by five small jet engines and fuelled by kerosene which is kept in the rider's backpack. So what's the CO 2 emissions of this thing? Should we be encouraging it? Can...

Re: E Bike - speeding?

My point was that saying that an electric bike doesn’t go as fast because one electric bike doesn’t go as fast as one non electric bike is a bit of odd statement. It’s not the electric (or otherwise) that makes that difference, it’s all the other design decisions and compromises which are made. You ...

Re: Roller brake hub

What’s wrong with a coaster brake? Brilliant little devices. For a cargo bike it's tricky to lift the bike up to reset the pedals for setting off. Is there a difference between roller and hub brakes (I thought they were the same thing)? Are roller/hub brakes any less effective than a coaster brake ...

Re: E Bike - speeding?

Taking an evils to 30+ is not significantly harder than taking a non assisted bike to 30+ For use mere mortals it will generally be gravity assisted, so the weight makes no odds. It is rather harder on mine! Not that I can do 30 mph on a non-electric, but reaching lower speeds is significantly hard...

Re: E Bike - speeding?

The reason why you can't be 'pulled' for speeding on any pedal bike is that there is no legal requirement to have an accurate speedometer on the machine. :D Not true - it’s that there is no speed limit. You can be pulled for speeding where there are bylaws imposing a speed limit on cyclists (royal ...
