Re: Electric car charging to kill off segregated cycle lanes

When you think about cross rail, they could have used the East to West tunnel simply for bikes and it would have had a greater capacity by far than the trains and at a hugely lower cost. Is this correct? A figure of 14000 people per hour is sometimes quoted as being the number of people who can be ...

Is it worth having a flexible steel fork on a recumbent?

I have decided to try superman handlebars rather than tiller on my Metabike. The stem for the superman bars requires a much longer section of steerer to clamp onto, so it looks like I am going to need to get new forks. Is it worth having flexible steel forks on a recumbent? I feel that the bumps are...

Re: Electric car charging to kill off segregated cycle lanes

My understanding is that there are considerable doubts over whether using vehicle batteries to support the grid makes economic sense. Vehicle batteries only have a limited number of charge cycles, so if they are used to supply electricity to the grid then it shortens the batteries' life. It may be b...

Re: Getting into the recumbent cycling

Hello Quicksilver

Perhaps if you switch to clip-in pedals and cycling shoes, you will be able to comfortably spin a bit faster. If you know that your feet are securely attached to the pedals, you can relax more and focus on spinning.

Re: Electric car charging to kill off segregated cycle lanes

It seems to me that there are three questions being discussed here: 1. Are electric cars any good? 2. Are segregated cycle paths any good? 3. Will electric car charging points interfere with cycle paths? I think electric cars probably do have some role to play in the future, but I think they are als...

Don't forget the latent heat of vapourisation!

If the water boils, it absorbs 2260000J/kg!

Re: Front platform rack

Perhaps you could get the brake boss rack and use jubilee clips to attach the brake mounting points to the fork legs?

It's probably not what you are after, but I have the Steco head tube rack and I like it.

Re: Why isn't there a cycles on trains campaigns from Cycling UK?

I sometimes take my SWB recumbent on the train. It fits OK in a standard bike space. A LWB recumbent would be a different matter - it would be classed as a tandem in my view. I think that a maximum length should be defined for a "standard bicycle", and anything longer than this is classed ...

Re: Why isn't there a cycles on trains campaigns from Cycling UK?

Vorpal asked: What are cycle spaces, and where do Tandem and Trailer go? I think it would be good if a standard bicycle were defined. If the standard bicycle doesn't fit easily in all the cycle spaces, they are not cycle spaces. The standard bicycle should be large - I suggest the largest-framed men...

Re: Shimano 12-speed

I think perhaps these cassettes with very large sprockets and lots of gears could be useful for recumbents, although I am sure this is the last thing the designers had on their minds! I have a few reasons for thinking this: -Recumbents benefit from having low gears, but using very small chainrings t...

I'm in Loughborough.

There is also a guy who goes to the same Pilates class as me who sometimes rides a recumbent.

Re: Pashley type bikes

I have ridden a Dutch roadster ... they don't go up hills ... I think that riding in different positions uses muscles in different ways. Therefore, if someone who is used to a fairly aggressive riding position tries riding in a very upright position, they may be lacking in power because they are no...

Re: Shifters for hamster bars

I think it's good that your shifters have an indicator showing which gear you are in. Mine don't, and I find this a nuisance. It's easy to shift to the small chainring when coming to a stop, but not realising that the rear derailiuer is in a very small gear. It's then a pain trying to get moving aga...

Re: Why isn't there a cycles on trains campaigns from Cycling UK?

I suspect it might help towards such a policy if we cyclists were clearer about quite what we wanted. Yes, this is a good point. I can't speak for everyone, but I'll set out below what I would like to see. I've divided this up according to the type of rail route: commuter routes, fast inter-city se...
