Yes, the problem was that they temporarily closed the Patent Office because the government officials running it couldn't think of any more inventions that could be registered. All the employees were given redundancy notices, but finally, they had to cancel them when more applications came in. That's caused a big backlog.Which pretty much confirms my post #11 about waiting on the Gravity Cancelling device patent flecc!
Had a look at the Nano conversion and note that the battery used is the same Bosch one as used by ARCC innovations in their e-assist conversion of the Brompton. Odd that the range of the Nano is so much shorter (16-18 miles) as opposed to the approx 30 miles quoted by ARCC. In reality I find the range of my Moulton to be around 26 miles.
I'm not sure if the original Nano Brompton small battery was the same, but David Henshaw got 41 miles in his test!
Looking at the image on his website it appears to be the Bosch 4AH battery...the same as mine. I'm 12 stone and on a moderately hilly course I can manage around 26 miles using the lowest level of assist so I have to agree with the post above that this achievement of 41 miles is in the realm of those mpg's given by motor manufacturers. Using a higher assist level dramatically decreases the range of course but then there's always so many factors involved in quoting mileages achieved.
Why wait? I have been very happy with my sparticle converted brompton, it has done over 5000 miles now and we take it all over the country in the car
