Not sure how efficient the charger is, probably reasonably so. A 500wh battery is 1/2 hwh,. Typical domestic cost is around 15p per kwh (unit), maybe a bit less; that gives 7.5p per charge. 15ah 36v battery would be 150wh, around 8.5p.

That is a much more active forum than this one.

In the more expensive ranges, Cube Touring and Raleigh Motus. Lower price look at Woosh (for full bike of for conversion kits) or Juicy.

I don't know how good Luna support is, but you may find you may get a quicker answer if you post on Pedelecs.

There are several people on that forum with much more detailed technical knowledge than most posters here (including me).

Did it work and then stop working, or has it never worked properly?

Good comment on the Crosspath near the end of thread https://www.pedelecs.co.uk/forum/thread ... e-7.33486/

And don't forget the CTC discount for Halfords.

Look on Pedelecs and post there; a wider audience than here. https://www.pedelecs.co.uk/forum/forums ... -i-buy.40/

Cube have a very good reputation, and so does the Crossfuse. Avoid the Crossfire from what I have seen on Pedelecs (but it wasn't on your list anyway).

Also worth looking at Woosh, for example http://wooshbikes.co.uk/?krieger. That will come in well below your budget, even with the biggest battery. One issue is you can't easily try one unless you are near Southend, or sometimes they can manage for you to try somebody else's more locally. One thing ...

Woosh has already been suggested above for hub kits ... I will second that. They also do mid drive. http://wooshbikes.co.uk/cart/#/category ... rsion-kits I haven't tried their mid-drive, but they are certainly very helpful and will give advice by email or phone.

Possibly not at hill climbing speed.

Unless the very fit user is able to provide 750w up the hills to keep the speed up and the motor working at its best? But maybe then she wouldn't want the motor anyway.

What sort of speed do you normally tour at unassisted? We've never been that sporty; mainly 5 mile extended shopping trips or 20 mile half-day trips rather than tours. Many years ago (age 30-40) I could keep up 18mph on the flat but 15 was more usual. Later (age 50-60) 12 became more my norm, and n...

Our tandem is a fairly basic Viking, not particularly light but sensible components on the whole, and I guess we come in at around 24 stone, 150kg. The Woosh kit we used was the front XF07 with the 13Ah battery. This was partly because of what was available for 700c wheels at the time we bought. Als...

Weight can also make a big difference on downhill speeds; smaller people's air resistance does not reduce as much as their weight does. If you get a tandem you will find that you both keep very much the same speed all the time, and faster than either bike alone downhill (especially if you don't have...

I would like something with a battery that could easily be removed and charged up over a lunch time break in a pub. Most batteries take quite a long time to charge (3-4 hours), so either a long lunch or just a partial charge. There are faster chargers but they can reduce battery life. Cytronex http...
