Re: Wind and Solar vs Coal, Gasoline, Nuclear

.?? Heavily dependent ?? You may want to check your sources. France, like most European countries, works with its neighbours to balance demand across the European grid. It certainly imports power from Germany, (and others ), but it is a net EXPORTER of power to all its neighbours ! As often with am...

Re: Wind and Solar vs Coal, Gasoline, Nuclear

We can see on average year after year how wind/solar states ultimately emit as much as 10 times more co2 than nuclear-based France. If we were comparing these co2 stats as if they were two different cars then the "wind/solar renewables car" would be considered a bad extreme polluting joke,... In re...

Re: Wind and Solar vs Coal, Gasoline, Nuclear

Population will shrink again after 2050, maybe a bit sooner. Difficult predict over long times. 80% of world population will live in large cities by than. In large cities not every person needs a car. 1 car for 5 persons should do it easily. Maybe we find solutions for even less car ownership, this...

Re: Hub motor industry dying?

Only politicians can call ‘speed’ a 500w bike. When laws are stupid, riders don’t need to be. In most places anyway, the police does apply the traffic rules and don’t care about the power of a bike. My "250W" speed Pedelec are good enough for 50km/h+ if they are unlimited. I limit them to 45km/h wh...

Re: SURVEY: Your watts at various speeds

The Milan numbers are very cool. Sadly a legal 45km/h version is not available. Direct drive with regen would be preferable imho to use regenerative braking and for less noise inside this hull and for the option to move backwards using the motor drive. But a DD limited to 25km/h with motor drag abov...

Re: Hub motor industry dying?

Not sure if this is getting too OT, but S-Pedelec is not really an interesting category in Europe. Sure you can ride a little faster, but since it's considered a lightweight motor vehicle it basically means you cannot use any of the bicycle advantages, ie. bike lanes. You are stuck with the stench ...

As for how will we produce 5 billion EVs? I don't know - the world doesn't need 5 billion vehicles. The world needs less than a billion vehicles, but these should all be electric as they consume fewer non-abundant resources than ICE. There are 788 cars for 1000 people in the US and 488 cars for eve...

I can't say anything about the quality. Would't expect much at less than 1000 Euro. But 12.5kg _is_ light. The 20 cell battery (10s2p) should be good enough to ride enough km for short commutes.

Re: 18% regeneration?

The regen quote on CA3 is measured different from industry standards. The "quote" in CA3 is not Energy regen/ Energy consumed as usual, but Energy regen / (Energy consumed- Energy regen) So in industry standard if you consume 100Wh but gain 50Wh from regen your regen quote would be 50% On the CA3 th...

Re: Do you prefer freewheel or cassettte for your hub motor?

Sunrace also makes a 11t geared 9 speed freewheel but it costs a pretty penny and will not fit within standard 135mm drops. The Sunrace MFEX9-9AU 9x 11-32 freewheel is expensive and together with smaller motors like the Bionx fits nicely into 135mm dropouts. The problem is that a strong rider on a ...
