What is the cadence of the motor where it's sweet spot is? That is the question you should be asking first. That is why I posted a link to a cadence calculator. From personal experience that one is spot on if your exact tyre size is in the list. The GSM is ever so slightly under my preferred...

No. About 16 wide spaced ones is enough to cover just about any terrain. Use this http://www.bikecalc.com/speed_at_cadence to calculate what you need depending on your terrain. My own personal ideal setup for a 28" wheel bike (Number Two for example) would be the Sunrace 8 speed 11-40 with...

Maybe your PAS disk is broken?

You can add a double chainring to the Yamaha so Mont Ventoux should not be a problem.

With the KT controllers there seems to be a difference in start up speed between 8 and 12 magnet disks. It may be completely subjective but I find the 12 magnet disk gives a smoother, quicker feel to start up.

:rolleyes:

Braking a bike tire regularly from over 60 km/h yes, they are built for a little bit less and with soft sticky rubber to improve adhesion especially in the cold and wet.

Ah! Death and taxes... The Trump tax cut is a wonderful example of what is going on in the world. Tax cuts for everyone... earning more than $100k. Corporate rate down to 20% yet small business rate stays at 25%. There is your social justice clearly printed out, the less well off are on this...

I just cut the cable gain and put the end protection back on, 2 minute job.

You may disagree but my comment on claimed range for given power was not negative, it was realistic. If you want negative comments about hydrogen cell EVs I do have a heap of those on stock. The fact is that you can only "instantly recharge" the hydrogen, not the battery. Mail runs don't work...

They are only selling to the post office for the moment.

So at 35 km/h you are still a bicycle and at 45 km/h you are a moped. This would sign the death of the s-pedelec. OK so in France it is already dead... :(

It was tongue in cheek. I don't provoke people with dangerous weapons in their hands!

They have been arrested for rebellion against the state ( organising and holding the referendum). Woosh is correct, the PP refused to even talk about modifying the constitution, all the other parties to the left of them are for a brush up of the constitution. Had the PP said OK lets modify the...

This thing is as heavy as a tank, the weight was published in the local newspaper and from memory was 28 kg(?). Add in the bags full of mail you are going to need more than 5.4 Ah of hydrogen + 5.4 Ah of buffer battery to get any range. We all know what it is like riding with a battery just...

A golf robot that shoots par would make a great POTUS... :D

If you run out of hydrogen and run the 150 W buffer battery down to flat you are going to have to recharge the buffer battery back up to a certain level before taking off again. At 2 Amps it will take some time to charge back up presuming they are using standard 18650 cells in the buffer battery.
