Re: E-Bikes rules/Law

EAPC is still a PC, so no regulations which specify mechanically propelled or motorised vehicles apply. OTOH some electric bikes won't be EAPC according to the law - they are basically electric motorbikes in the eyes of the law, so need registration, insurance, VED, motorbike standard helmet... 250W...

Re: Old is new again, speedo

I had one of those on my bike as a kid - fabulous fun seeing how fast I could go across the field on my racer.... Even remember which bit of the field we used to use (most of the rest of the common route was tie path, and didn’t really lend itself to straight line speed - this bit cut off a big curv...

Re: Brightest Rear Light for Daytime Use

More important than ‘can you see these lights’ is ‘do these lights make a difference to your safety’ To make a difference they have to be the difference between being visible from somewhat less than the motorists stopping distance (since you are moving as well) and not being visible in that range. A...

Re: HPV grasshopper rear wheel offset ?

Surely a grasshopper rear wheel should be dished as normal so rim is centred between dropouts. I don't know if the GH dropouts are centred on the vehicle (or the desired rear wheel position). ICE trikes have an offset rear triangle, so that a conventional wheel is undished in use (i.e. spoke length...

Re: HPV grasshopper rear wheel offset ?

IIRC the wind cheetah has it quite substantially offset by design.

Re: HPV grasshopper rear wheel offset ?

ICE trikes are offset to make the wheel strength symmetrical.

Don't need to dish a wheel at the rear of a trike (heck, it doesn't even need to run the middle of the two front wheels )

So I'd guess that it was built centred between the flanges, not the OLN.

Re: Carrying a child's bike

The steering will hold itself straight, most of them also have a ‘lowest angle’ they’ll run at, so you could just lift the front wheel for kerbs etc.

Re: Should I convert to a Rohloff hub - costs vs benefits ?

It’s also depends on the alternatives - there are other fairly wide IGH systems for somewhat less, with maybe a few feeer gears, or slightly varied jumps, it’s not as if the rohloff is clearly bad value - it’s wonderfully engineered. I think I’d struggle to justify over, say, an 11 speed from elsewh...

Re: Is getting on a stop after your train ticket start point illegal in England?

Price per mile, with a variants for: - service class (ie first class costs more) - time of day (the miles you travel during some sane definition of peak periods, not the current 2-7 and anything up to 10am rubbish) - service speed (do express trains deserve a fare boost?) Really should be that simple.

Re: Pedals suitable for barefoot shoes ( ultra-thin soles )

Got some pyros coming in the post...
Been playing with various ideas, worst case they’ll go back on eBay...

I suspect they’ll be very good for me, slight concerns:

- theft
- expect depth of toebox
- potential wear at rear of shoe
