If you are commuting on the flat why not. If there are hills involved you are wasting your time with those cells. The only solution is to do what Tesla does and go massively parallel = big battery and lots of weight. By massively parallel I mean at least 10P. That could be 2 x 5P7S batteries...

I got mine direct from DNP. With shipping it worked out about the same price as it would have if d8veh shipped from the UK...

Yes but when it is your only option it is a life saver - my 2013 Google nexus 7 tablet has a faulty USB charging interface and can only be charged by induction now. So it is a bad idea which has some uses. :)

I found this thread which I now remember reading a couple of years ago when I was building the freewheel Mxus bike: https://endless-sphere.com/forums/viewtopic.php?f=3&t=62844 So it is possible to disassemble DNP freewheels and swap cogs around. Of course gear changing may be affected - some...

When you look at the prices of chains and cassettes as I have been recently (thinking of going to 2 x 10 instead of 3 x 8) the difference between running costs compared to performance benefit seems to be in favor of a 10 speed.

Some of us have done thousands of km sitting on one, I think if it created knee problems you would be hearing about them.

It doesn't bounce, it absorbs the shocks, the pogo stick ones bounce. It does move slightly forwards but not enough to change your riding position. They really are the best invention since the bicycle IMO...

And those stupid French spies saying there was no such thing, luckily you believed the right people... :cool:

Keeping the dishing to a minimum was my goal in getting rid of the 1.x mm or so and getting the 8 speed down from 38.9 mm to as close to 37 mm as possible. There is already a 6 mm dish with the xiongda. As there is now a sensored option for this motor there ara a couple of wheels I'd like to...

Looking at the DNP 7 speed freewheel I have here it looks like one could machine about 1.8 mm off the rear and front lock rings. I was wondering if an 8 speed 13-34 could be brought down to 37 mm stack height thus fitting one of the tiny Xiongda rear freewheel motors...

Which just goes to show how tired you are when you ride home! :)

What freewheel are you going to use on that motor? I have a DNP 11-32 7 speed here for my Mxus and after studying it I think about 1.5 mm can be machined off the stack height. I am looking at the DNP 13-34 8 speed which has a stack height of 38.6 + or - 0.3 mm which I would like to get down to...

I can understand wanting a motor/gearbox combo with a full suspension bike - keep the rear wheel as light as possible and center mass. But in a city bike? Really? Another "problem" that didn't need solving or more profit for large companies that don't make enough already...

The insulation looks pretty far gone in a couple of spots, the pros will give their opinion. My earlier bout of laughing was me visualising the scene, sorry bout that! Reminded me of a couple of moments I have had myself.

The UK is in infraction with several EU directives already I think what OG is saying is that won't get any better when you leave.

Knowing that Bafang doesn't deal directly with end users or even small re-sellers, they only talk to the big fish. If you kill someone with your bike the police might peel away the sticker to see what is underneath. If you ride responsibly nobody will even think of looking at your motor let...

Merkel can't talk or decide in the name of the EU and I wonder if she can in the name of Germany?

The Normands... :rolleyes:

French law is similar a bike has to be sold with a bell and lights. Lights have to be on from legal hour of sunset (when the bottom of the sun touches the horizon) till daybreak. Reflectors on wheels etc. etc. Bad news: a bell is of no use when someone has the headphones of their phone firmly...

Ohhh! a big kiss on the cheeks for that. Much cheaper making a 12S (50.4v) charger from a spare 42v one than having it flown in from China! Yes you said 50.2v and I said 50.4v but I think that 0.2v is within balance tolerances...
