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 ...

Re: E Bike - speeding?

I think that the OP may have meant the 15mph limit for e-bikes. I think anyone who could do 30 mph on an e-bike without electric assistance would be a useful rider. I can, regularly. Used to average 17+ on my 15 mile commute (including time at lights etc) Taking an evils to 30+ is not significantly...

Re: Front wheel locked while cycling: disc brake or mudguard?

That's sounding like full on negligence now - even when the problem has been highlighted they are still saying "nothing wrong here, no-one else has complained"

Re: Trident Trike

The adventure is a decent trike, very well made and specced.

ICE are UK based. And have excellent after sales support.

£2k for a decent condition adventure doesn’t seem overpriced, so you would likely recoup most/all of that if you look after it and still decide it’s not for you.
